shaft with drive tang on lower end of distributor

drive shaft.

OIL SEAL (REAR MAIN)

Replacement

The rear main bearing oil seal can be replaced (both

halves) without removal of the crankshaft.
Fig.
12V - Removing Torstonal Damper

NOTE:
Always replace the upper and lower

seal as a unit.. Install with the lip facing toward

the front of the engine.

With the oil pan and oil pump removed, remove the

rear main bearing cap.

Remove oil seal from the groove by prying from the

bottom with a small screw driver (fig. 10V).

Lubricate the lip of a new seal with engine oil. Keep

oil off the parting line surface as this is treated with

glue. Insert seal in cap and roll it into place with

finger and thumb, using light pressure so seal tangs

at parting line do not cut bead on back of seal.

To remove the upper half of the seal, use a small

hammer to tap a brass pin punch on one end of seal

until it protrudes far enough to be removed with

pliers (fig. 11V).

NOTE:
Always wipe crankshaft surface clean

before installing a new seal.

turning crankshaft, until seal is rolled into place.

(Similar to installing a main bearing.) Be careful

that seal tangs at parting line do not cut bead on back

of seal.

Measuring Lobe Lift

NOTE: Procedure is similar to that used for

checking valve timing. If improper valve opera-

tion 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. 26V).

3.
Rotate the crankshaft damper slowly in the direction

of rotation 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 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.
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 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).
