FIGURE 61. FRONT BEARING INSTALLATION
Before installing the front bearing, use the Locktite
Bearing Mount furnished in the bearing kit. Use the
towelette in the package to clean the outside of the
bearing and the bearing bore in the block.
After allowing three to four minutes for drying, apply
the Locktite Bearing Mount from the small tube to the
mating surfaces of the bearing and bearing bore.
Install the bearing flush with the block using the
combination driver just used for the rear bearing.
Wipe off any^excess, Locktite around the bearing.
Allow at least one hour for hardening at room
temperature.
Lubricate the front main bearing lightly with oil and
insert the crankshaft. With the rear bearing plate
gasket in place and the rear plate bearing lubricated,
slide the thrust washer (grooves toward crankshaft)
and plate over the end of the crankshaft. Line up the
notches of the thrust washer with the lock pins before
tightening the end plate or the lock pins will be
damaged.
A light film of oil on the thrust washer may hold it in place while
installing the crankshaft.
CRANKSHAFT
ENDPLAY
After the rear bearing end plate has been tightened
using the torque recommended in Assembly Torques
and Special Tools, check the crankshaft endplay as
shown in Figure 62. If there is too much endplay (see
Dimensions and Clearances for minimum and max-
imum endplay), remove the rear bearing end plate
and add a shim (Figure 60) between the thrust washer
and plate. Reinstall the end plate making sure the
thrust washer and shim notches line up with the lock
pins.
Torque and recheck endplay of the crankshaft.

ed contact with skin can be harmful. Be sure
