inside the radiator channel. Lift the radiator up
and out of the channel.
19. Remove the two front engine mounting bolt nuts.
20. Drain engine oil.
21. Disconnect the rear end of the propeller shaft at
the rear axle companion flange, lower shaft and
pul1 rearward out of transmission. Remove
transmission.
22. Remove the nuts from the clutch throwout lever
release rod.
23. Attach motor lift bracket and raise engine up and

CRANKSHAFT REMOVAL
1. Remove the flywheel housing dust cover.
2. Remove the clutch. See "Clutch Removal", and
remove the flywheel.
3. Remove the oil pan.
4. Remove the vibration dampener cap screw,
lock, and remove the vibration dampener. Us-
ing Puller J-5371, Figure 14. See "Vibration
Dampener Removal".
FIGURE 14
Do not hammer on dampener to remove.
5. Remove gear case cover.
6. Remove camshaft gear and timing chain.
7. Using Puller J-471, remove the crankshaft gear
(Figure 15).
8. Remove connecting rod palnuts, attaching nuts
and remove connecting rod caps. Be sure caps
are installed on connecting rods
9. Remove front and rear main bearing caps using
Bearing Puller J-2955.
NOTE: The No.2 and No.3 main bearing caps
can be reversed in error, therefore place punch
marks on caps and cylinder block to insure
that caps are returned to their original posi-
tion.
10. Remove No. 2 and No. 3 main bearing caps.
11. Lift out the crankshaft.
12. Remove the connecting rod and piston assemblies
from the cylinder block and carefully place them
on the work bench and cover them with a clean

13. Use clean rags in bores of cylinder to catch any
foreign material during replacement of crank-
shaft.
FIGURE 15
Before installing the crankshaft a n d bearings,
the crankshaft should be checked for wear, out of
round and taper. The limit on out of round and
taper of main bearing journals should be no greater
than .001". Check with micrometers horizontally
and vertically.
The recommended main bearing clearance is
.0005" to .0015". Proper clearance can be checked
by either the plastigage or shim methods.
To check clearance with shim stock, remove
one bearing cap at a time. Install a pie ce of brass
shim stock, .002" thick by 1/2" wide by 1" in
length c r o s s w i se in the bearing. Oil the shim
stock freely to avoid bearing or journal damage.
Tighten the bearing cap bolts to a torque of 75 to
80 foot pounds. A considerable drag indicates
