CASE POROSITY-REPAIR

Transmission leaks caused by aluminum case porosity

have been successfully repaired with the transmission in

the vehicle by using the following procedure.

1.
Road test and bring the transmission to operating

temperature.

2.
Raise the car and, with the engine running, locate the

source of the oil leak. Check for leaks in all operat-

ing positions.

NOTE:
The use of a mirror will be helpful in

finding leaks.

3.
Shut off engine and thoroughly clean area with a sol-

vent and air dry.

4.
Using the instruction of the manufacturer, mix a suf-

ficient amount of epoxy cement, part #1360016, to

make the repair.

5. While the transmission is still hot, apply the epoxy

to the area, making certain that the area is fully

covered.
6. Allow epoxy cement to dry for three hours and re-

test for leaks, as outlined in Steps 1 and 2.

OIL PRESSURE CHECK

With Car Stationary

Transmission oil pressure gauge and engine tachome-

ter should be connected and the oil pressures should

check as follows:

1.

GENERAL DESCRIPTION

All Sedan models (fig. 1) use a 24 gallon capacity

(approx.) fuel tank mounted between the frame rails

behind the rear axle. The fuel tanks are held in place

by two straps attached individually to the underbody at

each end. The strap? hinge at the forward end and secure

the tank at the rear with a nut and bolt. Anti-squeak

material is cemented to the tank at the strap locations.
A vent line from the forward-right side of tank extends

over a clip on the upper portion of wheelhouse.

The station wagon fuel tank has a 24 gallon capacity

(approx.). The tank is located at the back of the left rear

quarter wheelhouse area. The front of the tank is en-

closed with a protective shield (fig. 1).

Draining Tank

The absence of a drain plug in the gas tanks makes it

necessary to siphon fuel from the tank when draining is

needed. The following procedure is recommended.

1.
Obtain approximately 10 feet of 3/8" I.D. hose and

cut a flat-type slit 18" from one end. Make this cut

on the hose in the direction "toward the shorter end

(See Figure 2).

2.
Insert a small pipe nipple (slightly larger O.D. than

the hose I.D.) into the opposite end of hose.

3.
Insert the nipple end of the siphon hose into the fuel

tank filler neck with the natural curl of the hose

pointing down. Insert until the hose is heard to strike

bottom of the tank.

4.
With the opposite end of the hose in a suitable con-

taner insert an air hose in downward direction in the

flap-type slit and trigger the flow of fuel.

CAUTION: Always drain gasoline from com-

plete fuel system including carburetor, fuel

pump and all fuel lines and fuel tank if the vehi-

cle is to be stored for any appreciable length of

time. This precaution will prevent accumulation

of gum formation and resultant poor engine

performance.

vehicle. The fuel lines should be occasionally inspected

for leaks, kinks or dents. If evidence of dirt is found in

the carburetor or fuel pumto and disassembly, the lines

should be disconnected
and
blown out. Check the fuel tank

strainer for damage or omission. Note position of fuel

line clips for convertible models.
FUEL TANK VENT LINE

Sedan modei fuel tanks are vented to the atmosphere

at the top right- forward edge of. the tank. The vent line

is connected by a rubber hose with two clamps one at the

tank and the other at the vent pipe which is secured to

the underbody A rubber grommet around the vent pipe

acts as a seal to prevent gasoline fumes from entering

the.passenger compartment.

IMPORTANT: It is important to note that the

sedan gas tank cap is non-vented. It is neces-

sary to be assured that the vent line is free from

dirt, etc., and open at all times. If gasoline

fumes are detected, the rubber grommet should

be checked.

Station wagon models use a vented, anti-surge type gas

tank.
