a vise using leather or wood on each side to prevent

damage to the cylinder,

7. Stake the retainer securely in place by staking the

cylinder metal over both edges of the retainer ends

using a suitable staking tool at right angles to the

top of the retainer and from the cast metal of the

cylinder over the retainer at each corner.

PUSHING, TOWING AND LIFTING

Pushing

NOTE:
Towing car to start is not recommended

due to the possibility of the disabled car ac-

celerating into tow car.

AUTOMATIC TRANSMISSION

Do not attempt to start the engine by pushing the car.

Should the battery become discharged, it will be neces-

sary to use an auxiliary battery with jumper cables to

start the engine.

CAUTION: To prevent damage to electrical

system, never connect booster batteries in ex-
cess of 12 volts and connect positive to positive

and negative to negative.

Manual Transmission

When a push start is necessary turn off all electrical

loads such as heater, radio, and if possible, lights, turn

on the key, depress the clutch, and place the shift lever

in high gear. Release the clutch when your speed reaches

10 to 15 miles per hour.

TOWING

The car may be towed safely on its rear wheels with

the (selector lever in "N" (Neutral) position at speeds

of 35 miles per hour or less under most conditions.

However, the drive shaft must be disconnected or the

car towed on its front wheels if 1) Tow speeds in excess

of 35 MPH are necessary, 2) Car must be towed for ex-

tended distances (over 50 miles) or, 3) Transmission is

not operating properly. If car is towed on its front

wheels, the steering wheel should be secured to maintain

a straight ahead position.

at sealing area.

(Tool J-971 may be used as support.)

Without Cover
Removal

1.
With crankshaft pulley and nub or torsional damper

removed, pry old seal out of cover from the front

with a large screw driver, being careful not to dam-

age the seal surface on the cover.

2.
Install new seal so that open end of seal is toward the

inside of cover and drive it into position with Tool

J-8340 (fig. 13L).

CAMSHAFT

Measuring Lobe Lift

NOTE: Procedure is similar to that used for

checking valve timing.. If improper valve

operation is indicated, measure the lift of each

push rod in consecutive order and record the

readings.

1.
Remove valve mechanism as outlined.

2.
Position indicator with ball socket adapter on push

rod (fig. 14L).

3.
Rotate the crankshaft slowly in the direction of rota-

tion until the lifter is on the heel of the cam lobe.

At this point, the push rod will be in its lowest

position.

4.
Set dial indicator on zero, then rotate the crankshaft

slowly, or attach an auxiliary starter switch and

"bump" the engine over, until the push rod is in the

fully raised position.

CAUTION: The primary distributor lead must

be disconnected from the negative post on the

coil and the ignition switch must be in the ON

position. Failure to do this will result in a

damaged grounding circuit in the ignition switch.

5.
Compare the total lift recorded from the dial indica-

tor with specifications.

6. Continue to rotate the crankshaft until the indicator

reads zero. This will be a check on the accuracy of

the original indicator reading.

7.
If camshaft readings for all lobes are within specifi-

cations, remove dial indicator assembly.

8. Install and adjust valve mechanism as outlined.

Removal

1.
Remove valve lifters as outlined,

2.
Remove crankcase front cover as outlined.

3.
Remove radiator as outlined in Section 13.

4.
Remove grille as outlined in Section 13.

5.
Remove fuel pump as outlined in Section 6M.

6. Align timing gear marks then remove the two cam-

shaft thrust plate bolts by working through holes in

4.
Set dial indicator on zero, then rotate the damper

slowly, or attach an auxiliary starter switch and

"bump" the engine over, until the push rod is in the

fully raised position.

CAUTION: The primary distributor lead must

be disconnected from the negative post on the

coil and the ignition switch must be in the on

position. Failure to do this will result in a dam-

aged grounding circuit in the ignition switch.

5.

tor with specifications.

reads zero. This will be a check on the accuracy of

the original indicator reading.

7.
If camshaft readings for all lobes are within specifi-

cations, remove dial indicator assembly.

8. Install and adjust valve mechanism as outlined.

Removal

1.
Remove valve lifters as outlined.

2.
Remove crankshaft front cover as outlined.

3.
Remove grille as outlined in Section 13.

4.
Remove fuel pump push rod as outlined * in Sec-

tion 6M.

5.
Complete camshaft removal as follows:

CAUTION: All camshaft journals are the same

diameter and care must be used in removing

camshaft to avoid damage to bearings.

Remove camshaft sprocket to camshaft bolts then

remove sprocket and timing chain together. Sprocket

is a light fit on camshaft. If sprocket does not come

off easily a light blow on the lower edge of the

sprocket (with a plastic mallet) should dislodge the

sprocket.

Install two 5/16" - 18 x 4" bolts in camshaft bolt

holes then remove camshaft (fig. 27V).

1.
Lubricate camshaft journals with engine oil and in-

stall camshaft.

2.
Install timing chain on camshaft sprocket. Hold the

sprocket vertical with the chain hanging down, and

orient to align marks on camshaft and crankshaft

sprockets. Refer to Figure 20V.

3.
Align dowel in camshaft with dowel in hole in cam-

shaft sprocket then install sprocket on camshaft.

Refer to Figure 25V.

4.
Draw the camshaft sprocket onto camshaft using the

mounting bolts. Torque to specifications.

5.
Lubricate timing chain with engine oil.

6. Install fuel pump push rod as outlined in Section 6M.

7.
Install grille as outlined in Section 13.

8. Install crankcase front cover as outlined.

FLYWHEEL

Removal

With transmission and/or clutch housing and clutch

removed from engine, remove the flywheel.

Installation

1.
Clean the mating surfaces of flywheel and crankshaft

to make certain there are no burrs.

2.
Install flywheel on crankshaft and position to align

dowel hole of crankshaft flange and flywheel (fig.

28V).

NOTE: On Automatic Transmission equipped

engines, the flywheel must be installed with the

flange collar to transmission side (fig. 33V).

ENGINE MOUNTS

Engine mounts (fig. 34V) are the nonr adjustable type

and seldom require service. Broken or deteriorated

mounts should be replaced immediately, because of the

added strain placed on other mounts and drive line

components.

Front Mount Replacement

1.
Remove nut, washer and engine mount through-bolt.

2.
Raise engine to release weight from mount.

3.
Remove mount from engine.
