General Description
The 1956 bodies, while basically the same as in 1955, incorporate many changes and additions in service information. These changes and additions have been included in this manual where appropriate.
The Chevrolet body has been completely redesigned to give greater strength and rigidity to the body. Fabrication and manufacturing processes have undergone radical changes to insure body shell alignment and dimensional control.
The cowl and dash now includes a shroud-length panel forming an enclosure, called a plenum chamber, which is utilized for the cowl intake ventilation system. In addition, this panel gives double wall strength to the cowl upper and side panels. The framework for the plenum chamber and the windshield pillars is formed by a heavy gauge one piece pillar facing. This facing wraps around the door opening section of the windshield and hinge pillar. A flared section at the upper and lower pillar joint is reinforced by a heavy gauge angle brace from the plenum chamber.
The column framed by the cowl side panels and the pillar facing is solidly supported by a heavy gauge reinforcement welded to base of the pillar and floor. Another heavy gauge brace is welded under the floor between the frame side members. Outrigger brackets, formed from "U" channels, are attached to the base of this 'box structure to form a body frame cross member eliminating the need for chassis frame second cross member.
The rear quarter inner panel from the door opening to the deck lid opening, including the deep drawn wheelhouse, is of one piece construction. The inner wall of the panel is ribbed at the rear and welded to the outer panel at the rear compartment opening. There is no welding seam at the formed wheel opening and by bringing the side walls of the rear end in line with the frame, resistance has been added to stresses on the body shell.
The gravel shield is integral with the lower end panel and the
package shelf is integral with the upper end panel to provide additional
resistance to torsional stress. Torque rod hinges which give full-travel
counter balancing of the rear compartment lid, rotary door locks and
rubber cushioned body mountings are a few of the many design changes in
the 1956 Chevrolet body.
Body Lubrication
Movable parts of the body are lubricated at the factory insuring proper operation. Those body parts which have frequent use, such as door locks etc., should be lubricated twice a year. Other body parts should be lubricated when access is available.
The following parts should be lubricated twice a year.
Wipe off all lubrication points before applying new lubricant. Remove all excess lubricant to prevent staining of trim parts.

Service Operations and Adjustments
WINDSHIELD WIPER ASSEMBLY
The windshield wiper assembly consists of a motor, auxiliary drive and two transmissions. The standard motor is vacuum operated and the optional motor is electrically powered. Both motors are interchangeable. The transmission incorporates spring loaded pulleys which provide for adjustment of the wiper cable tension. The wiper motor auxiliary drive incorporates two drums to which transmission drive cables are attached. The wiper motor and auxiliary drive assembly is installed to engine side of the dash panel. The motor and auxiliary assembly may be removed as a unit or the motor may be removed separately.
Transmission Cable Adjustment
The windshield wiper transmission drive cables are tensioned by spring loaded pulleys. The end of the transmission shaft is pushed in to unlock the pulleys. To tension cables push in on transmission shaft end if blade has been removed or on the base of the wiper arm if the blade is installed (Fig. 1).
To release cable tension for removal of components push in on transmission shaft end and have helper on the inside, pull on cables to obtain desired slack then release pressure on transmission shaft. NOTE: Wiper blade snap or over-travel is indicative of loose transmission drive cables.

Windshield Wiper Control
Removal and Installation
A single electric-type wiper motor powers both wiper blades on some models. Motor is mounted under center of dash panel as shown in Fig. 2.
Wiper is controlled by knob on dash panel. Turning knob clockwise selects either "Low" or "High" speed operation of wipers.
If wipers fail to operate (engine ignition switch must be "On"), turn control knob off (counterclockwise). Free wiper blades straight out from windshield glass only. Blades may be stuck or frozen to windshield.
CAUTION: Do not attempt to move blades by hand through their normal path of operation as damage to mechanism will result.
The electrical circuit to wiper motor may also be checked. Wiring connection must be kept securely tight.
Motor Replacement
1. Disconnect wiring at terminal front of cowl then follow instructions from "Wiper Motor, Replace."
IMPORTANT: Be especially careful when removing electric
windshield wiper assemblies for any reason not to lose the mounting
shims used between the unit and the dash panel. If the wiper is
reinstalled without using these shims, a binding condition results at
the wiper motor drive resulting in either sluggish operation or complete
stoppage of the unit.

Cowl Assembly
The 1956 Chevrolet incorporates a ventilating system with an air intake louver panel located on top of the cowl. The air entering the cowl top ventilator louver panel flows through a duct which guides the air into the body through an opening at each cowl side duct panel. The flow of air into the body is regulated by a valve in each cowl side opening; each valve is adjusted by the use of a cable and control knob. Water entering the inlet louver panel into the duct flows down the cowl side duct panel into a drain gutter which directs the water out of the body.

Door Lock
The front and rear door locks are the rotary bolt type lock and incorporate the new inter-lock feature consisting of a notch in the striker into which the rotary bolt housing extension engages. With the inter-lock feature it is very important that the lock extension engages properly in striker notch and that, where necessary, the correct striker emergency spacers are used to obtain proper engagement.
NOTE: Before installing door lock, apply a ribbon of caulking compound across the face of the lock frame approximately 3/4" above the rotary bolt housing as shown at "1" (see Fig. 11).
These service operations may be used for door locks on all models. However, in addition to the following operations, it is necessary to remove the door window and glass run channel, to remove the door lock from sport coupes and convertibles.
Operation
A rotary bolt type door lock is used on all models. Figure 29 and figure 30 show the door lock construction and striker with the names of component parts. When the door is being closed, the lock bolt rotates as it comes in contact with the striker, until it becomes firmly engaged with the teeth at the lower end of the striker. When the door is completely closed, the locking cam, shown in the illustration, is firmly locked by the detent lever (Fig. 29).
To open the door, the locking cam is released so that the bolt can rotate. This action is obtained by the operation of the push button or remote control handle.
Locking of the door by key or by the lock rod is accomplished in the lock in the following manner.

Front and rear door lock strikers incorporate the new inter-lock feature consisting of a notch in the striker into which the lock bolt housing extension engages. With the inter-lock feature it is very important that the lock extension engages properly in the striker notch and that, where necessary, the correct striker emergency spacers are used to obtain proper engagement.
Removal and Installation
IMPORTANT: Whenever a door has been removed and installed, or realigned, the door SHOULD NOT be closed completely until a visual check is made to determine if the lock extension will engage in the striker notch. Where required, door lock striker emergency spacers should be installed so that door can be closed and an accurate check made to determine emergency spacer requirements.

Inner Panel Sealing
Some of the front door inner panel weatherseals have been changed for 1956 styles. These changes are covered below. Whenever work is performed on a door where any of the door inner panel weatherseals have been disturbed, the area must be resealed before the door trim assembly is reinstalled.
Figure 12 shows door inner panel openings which are sealed to prevent water leakage and possible damage to the door trim assembly.
Front Door Adjustment
IMPORTANT: After performing any door adjustments on a convertible or four door sedan style the door ventilator and window should be checked for proper alignment with the side roof rail weatherstrip and adjusted where required. In addition, when performing adjustment on any style do not close the door completely without making a visual check to see that the door lock extension engages in the striker notch as specified.
Door adjustment is provided at the hinges through the use of cage nuts and anchor plates. When checking a door for misalignment, remove the door lock striker and allow the door to hang free on its hinges, then check the spacing at the sides and top of the door. After determining the type of correction needed, correct in the following manner:
Up or Down and In or Out
Up or Down and Fore or Aft
Should the door clearance at the body hinge and windshield pillars be parallel and fall within 1/16" to 3/16" clearances and the door at the center or lock pillar be tilted (close at the top, wide at the bottom or vice-versa) it is indicative of another type of correction, namely body shimming. In most cases, where adjustment of the doors cannot correct a door alignment problem, body shimming will be the answer. Figure 38 shows the location of all body mounting points and where shims may be added or removed to correct body alignment faults. In addition figure 39 gives the dimensional clearances of the doors at the pillars.
Door Lock Striker
The door lock striker provides an additional adjusting point, where the lock pillar side of the door may be moved in or out to conform to the general body contour.
Adjustment
Adjustment of the door lock striker plate is provided by floating anchor plates in retaining cages behind the body lock pillar or the center pillar facings. Serrations of the striker plates and anchor plates provide retention to hold the striker plates in the desired position.
To adjust the striker plate, the attaching screws should be loosened sufficiently to allow the striker plate to be moved by hand to the desired location. Scribing the position of the striker plate on the pillar, prior to loosening the attaching screws, will clearly indicate the amount the striker plate has been moved. Hammering or blocking the striker plate should never be attempted as damage to the serrations may result in the loss of proper tension. Hammering or blocking of the striker plate may also result in closing the lock bolt groove which will affect the lock operation because of a bind condition which develops at the lock bolt roller.

Weatherstrips
The front door weatherstrip is a one piece mechanically retained type with external clips formed from a wire insert extending through the length of the weatherstrip. The weatherstrip is secured to the door by snapping the weatherstrip clips into holes around the perimeter of the door. At locations "A" and "B," indicated in Fig. 13, a tab, which is an integral part of the weatherstrip, is secured to the door pillar. Along the cove area of the door the weatherstrip is cemented in place, and at location "C," a clip inserted into the weatherstrip is secured to the hinge pillar. After the weatherstrip is installed, sealer is applied through the inner panel access holes to the weatherstrip attaching clips along the bottom of the door.
A front door hinge pillar auxiliary weatherstrip is provided to direct any water in the cove area of the hinge pillar into a drainage hole in the hinge pillar. The auxiliary weatherstrip is cemented to the door hinge pillar and has two snap-on clips at the lower portion of the weatherstrip.

Description
The windows and front seat adjuster are operated by individual
12-volt reversible motors. Each motor incorporates an internal thermal
circuit breaker to prevent overloading. All other components of the
window and seat adjuster circuit are protected by an additional circuit
breaker which is in the power feed circuit.
Operation
The operation of the reversible motor is controlled by two motor
feeds running from the control switch to the motor. The motor is
grounded through its attachment to the body. By actuating the toggle
control switch in one direction a clockwise motor shaft rotation is
obtained, by moving the switch control in the opposite direction a
counterclockwise shaft rotation is obtained. On window installations the
motor drives the pinion gear which is meshed to rack portion of the
regulator sector providing an up and down movement of the regulator lift
arm. On seat installations, the armature shaft of the motor has a worm
cut in it. This worm drives another worm to provide the adjuster
movement.

Hydro-Lectric System
A newly designed hydraulic package unit has been incorporated in the Convertible bodies. The new unit consists of a 12-volt reversible type motor, a rotor-type pump with a non-adjustable pressure relief valve, two hydraulic lift cylinders, and an upper and lower hydraulic hose assembly. The new unit can easily be distinguished from the gear-type unit by the design of the fluid reservoir, and the hydraulic hose connections at the sides of the pump. It is important to note that the folding top cannot be operated manually on bodies having the new rotor-type pump.
Figure 93 shows the new unit installed in the body directly behind the rear seat back. Figure 94 shows an exploded view of the motor and pump assembly. The parts indicated by letters may be identified in the description.

(When Replacing Gear-Type Pump With Rotor-Type Pump)
NOTE: Component parts of the gear-type unit are available for service as they have been in the past; however, the complete gear-type motor and pump assembly is not available for service. Therefore, if a complete gear-type motor and pump assembly is being replaced, it is necessary to install the new rotor-type motor and pump assembly with special service adaptor hoses.
Disassembly of Reservoir Tube From Motor and Pump Assembly
Assembly of Reservoir Tube to Motor and Pump Assembly
Operation of the Folding Top
The principles of top operation with the rotor type pump are the same as those of the unit with the gear-type pump. When the control knob is pushed forward, the battery feed wire is connected to the red motor lead and the motor and pump assembly operate to force the hydraulic fluid through the hoses to the lower ends of the double-acting cylinders.
The fluid forces the piston rods in the cylinders upward, thus raising the top. The fluid in the top of the cylinders returns to the pump for recirculation to the bottom of the cylinders. When the control knob is pulled rearward, the feed wire is connected to the dark green motor lead and the motor and pump assembly operate in a reversed direction to force the hydraulic fluid through the hoses to the top of the cylinders. The fluid forces the piston rods in the cylinders downward, thus lowering the top. The fluid in the bottom of the cylinders returns to the pump for recirculation to the top of the cylinders.
Pump Assembly
The rotor-type pump assembly is designed to deliver a maximum pressure in the range of 240 psi. to 280 psi. The pressure relief valve opens when the fluid pressure reaches the range of 240 psi. to 280 psi. The information following outlines in detail the pump action when the motor is actuated.
Raising the Top
See Fig. 98.
When the red motor lead is energized, the motor drive shaft turns the rotors clockwise as indicated by the large arrow. The action of the pump rotors forces the fluid under pressure to the bottom of each cylinder forcing the piston upward. This action causes the fluid above the piston in each cylinder to be forced into the pump, which recirculates the fluid to the bottom of the cylinders. The additional fluid required to fill the cylinder due to piston rod displacement is drawn from the reservoir as indicated.
Lowering the Top
See Fig. 99
When the green motor lead is energized, the motor drive shaft turns the rotors counterclockwise as indicated by the large arrow. The action of the pump rotors forces the fluid under pres. sure to the top of each cylinder. This action causes the fluid below the piston in each cylinder to be forced into the pump which recirculates the fluid to the top of each cylinder. The surplus hydraulic fluid due to piston rod displacement flows into the reservoir as shown.
Fluid Control Valve
The fluid control valve consists of a rocker arm installed in the pump cover plate, and two steel balls. Fig. 100 shows the top surface of the pump cover plate. The dotted lines indicate the cavities on the bottom side of the cover plate. The cavities are designed to permit fluid flow between pump rotors and the reservoir.
Figs. 101 and 102 illustrate the operation of the fluid control valve.
Pressure Relief Valve
The pressure relief valve consists of two springs and steel balls assembled in the pump end plate assembly. Fig. 100 shows the location of the pressure relief valve openings in the cover plate. Figs. 103 and 104 show the pressure relief valve balls and springs. The pressure relief valve operates as follows: When the pump is not operating or is operating and is delivering a pressure below the range of 240 psi. to 280 psi., the relief valve balls are seated as shown in Fig. 103. When the pump is operating to raise the top and the fluid pressure reaches the range of 240 psi. to 280 psi., the relief valve ball at the pressure side of the pump unseats, as shown at Fig. 104, and the hydraulic fluid flows into the reservoir thereby preventing the pump from delivering a pressure of more than the range between 240 psi. to 280 psi. The same action takes place at the opposite side of the pump when the pump is operating to lower the top.
Checking Procedures
The mechanical and electrical checking procedures for checking the Hydro-Lectric System, which incorporates the rotor-type pump assembly, remain the same as 1955. The hydraulic checking procedure is outlined below.
Hydraulic Check Procedure
Failures in the hydraulic system can be caused by lack of hydraulic fluid, leaks in hydraulic system, obstructions or kinks in hydraulic or faulty operation of a cylinder or pump. A pressure gauge can be used to check the pressure of the pump. See "Checking the Pressure of the Pump
Checking Hydraulic Fluid Level in Reservoir
Checking Operation of Lift Cylinders
Checking the Pressure of the Pump
Failure of the Hydro-Lectric system where the cause is not readily evident, should be checked in the following sequence: Mechanical, Electrical and Hydraulic systems.
Mechanical Check
If top action is slow, check for mechanical bind.
Electrical Check
Battery
Folding Top Switch
Switch to Motor Lead Wires
Motor Unit
Check the operation of the motor by connecting first one lead of motor via a jumper wire directly to the positive post of the battery; if the motor operates check the other motor lead in the same manner. If motor operates, but will not operate when hooked into the wiring harness, check back over the wiring harness for shorts. A sluggish operating motor when hooked into wiring harness could be indicative of low voltage at the motor resulting from poor connection, poor motor ground or a short.
Hydraulic Checks
Hydraulic system failure can be caused by lack of fluid in the system, leaks, obstruction or kinks in lines, faulty lift cylinders or pump. Troubles in the hydraulic system can be readily located with a pressure gauge. Pressure should read between 240 psi and 280 psi when pressure relief valve opens.

Adjustment of Pump Pressure
Lift Cylinders
Lock cylinders are furnished for service uncoded, this necessitates the coding of all replacement lock cylinders.
The side bar type lock (Fig. 115) is used for the ignition, door and trunk lid on passenger cars. Glove compartment locks are wafer tumbler single bitted type having 4 tumblers on passenger cars. These locks are all coded the same allowing a usage of one key for all locks on the vehicle. To protect owners, automobile lock manufacturers stamp the lock number on the lock core, shaft, etc., where they will not show until the lock is removed.
To obtain the code number remove the door lock, the key number may be obtained from the lock core, shaft, etc., which will be the same on all of the other locks.
In addition, when a lock cylinder requires replacement the lock code number may be obtained either from the key, if available, or from the old lock cylinder which is being replaced.
Once the code number of the lock is obtained, look up this number in a key cutting book. There are two types of code booklets in general use, one which lists the cutting code by letter C, N, B and Y. Numbers or letters are always recorded from the head of the key to the end. Numbers may be transposed to letters to numbers as follows:
Code Book-Numbers Code Book-Letters
1 C
2 N
3 B
4 Y
All side bar locks furnished to the field by the Parts Department are uncoded, that is, they are furnished without tumblers, springs or spring retainers; these parts are serviced separately. The tumblers come in four different depths indicated by colors "C" for copper, "N" for nickel, "B" for black and "Y" for yellow. The side bar locks have six tumbler positions, and in looking up the cutting code, the following may be used as an example. After key code number is determined, either from key or from number stamped on lock cylinder refer to your code book and record the key cutting information as follows.

The numbers or letters (depending on code book) which are written above the cutting or tumbler position indicate the different color tumblers which are to be dropped into each tumbler slot of the lock: "C"-copper, "N"-nickel, "B"- black, "Y"-yellow.
NOTE: If code book used lists the key cutting code numerically, the numbers must be transposed to letters as previously stated in order to select proper color tumblers for installation into the lock.
In cases where a code book is not available, the diagram as shown in figure 116 may be used to determine the tumblers required to assemble an uncoded lock cylinder.
After the letters (C-N-B-Y) have been determined and written above the cutting positions the lock cylinder should be assembled as follows:
Lock Cylinder Assembly
This section contains general directions for the proper care of the interior trim of the car and the convertible top. Several types of cloth material are or have been used in the Chevrolet; Nylons, Gabardines, Broadcloths, Pile fabrics. They are distinguished in part by flat woven yarns as in the broadcloths and pile surfaces, upright fibers densely woven at right angles to the base of the fabric.
General Instructions
Dirt and dust particles should be removed every few weeks, or more often if car upholstery is subject to constant hard driving. This can be done with a whisk broom, carpet beater or vacuum cleaner.
It is essential that stains be removed from upholstery as soon as possible. If they are allowed to remain on the fabric for some time, they often become oxidized and removal is difficult, if not impossible.
There are two basic types of popular cleaners available to car owners: (1) Volatile Cleaners, colorless liquids, generally having carbon-tetra-chloride or naphtha as a base. (2) Alkaline Cleaners which have a soap base.
The Volatile Cleaners are recommended since they have great solvent powers for grease, oil and road grime. Alkaline Cleaners generally remove stains satisfactorily but at possible risk to the removal of the color from the fabric.
Cleaning Pile Fabric
Soap and water may be used in cleaning pile fabrics, providing the instructions which follow are adhered to closely. A neutral non-alkaline soap should be used with lukewarm water. The suds should be frothy, not watery. They should be applied in moderate quantities with a clamp cloth, sponge, or soft brush. Rub with the pile, not against it. Soapsuds should be removed with a clean, damp cloth or sponge. Then wipe the surface several times with a dry cloth. While still damp, brush lightly with a whisk broom or brush of medium stiffness. Permit air to circulate freely over the wet upholstery. When dry, brush again, against the pile.
The surface of pile fabrics can also be freshened by steaming. Spread a damp cloth over the surface and touch a hot flatiron to it lightly. While still damp, the upholstery should be brushed lightly with a whisk broom or brush of medium stiffness. When thoroughly dry, the material should again be brushed. Brush against the pile.
Cleaning Broadcloths, Nylons and Gabardines
Soap and water, regardless of the basic type of soap, is not recommended for cleaning flat cloths, particularly broadcloths.
Safety Precautions for Cleaning Fabrics
Cleaning Genuine Leathers and Imitation Leather
Care of genuine leather and imitation leather is a relatively simple but important matter. If dirt accumulates on the surface, this generates into a hard grit which under pressure will cut the finish and cause the leather to crock or bleed color. The surface should be gone over occasionally with a dry cloth and if dirt should accumulate, the following cleaning instructions should be used:
Lukewarm water and a neutral soap should be used and a thick suds worked up on a piece of cheesecloth and applied to the surface.
The operation should be repeated, using only a damp cloth and no soap.
The leather should then be wiped dry with a soft cloth. Polishes and cleaners used for body finishes, volatile and other clear cleaners, naphtha, furniture polishes, oils, varnishes or household cleansing and bleaching agents should never be used.
Cleaning Convertible Top Materials
The top materials are easily cleaned and kept attractive if the proper methods of cleaning and care, are exercised. Generally, soilage can be removed with art gum or crude rubber. If dirt is embedded in the fabric, the top should be thoroughly brushed with a whisk broom. In this brushing a minimum of pressure should be applied to those areas of the assembly which cover the metal bows of the top structure, since heavy abrasion will disturb the surface of the material appreciably, causing an unsightly appearance.
After brushing, the top should be washed thoroughly with a neutral soap suds and lukewarm water. A cloth or brush with soft bristles should be used. Generous quantities of clear water should then be applied over the surface to remove any soap which might remain. Volatile and other clear cleaners, naphtha, gasoline or household cleaning and bleaching agents should never be used.
After cleaning, always be sure that the top is thoroughly dry before folding it down. Folding the top while still wet or damp may cause mildew and unsightly wrinkles.
This precaution should also be taken by the owner in service. After rainfall, the top should be allowed to dry out thoroughly before being collapsed because, in addition to causing mildew and wrinkles, the top material will possibly shrink, after such abuse, to a degree that it may be impossible to return the top structure to its normal upright position.
Cleaning Carpet Floor Coverings
To clean carpet floor coverings, they should first be brushed thoroughly. If soil remains, a volatile type cleaner is recommended. The cleaning operation should be repeated for heavily embedded stains.
Extreme care should be taken by the owner to make certain that the carpets are not "soaked" with the cleaner. This may cause deterioration of the rubber compound backing construction of some carpets.
Neutral soap and water may also be used, at the risk of color removal, but the owner is cautioned to make certain that the carpets are thoroughly dry before closing all window and door openings to prevent possible mildew of the carpet.
