CRANKSHAFT REPLACE/REPAIR
0139 00
REMOVAL
1. Remove tie-rods (1) (through bolts) from crankcase (2).
NOTE
For ease of disassembly, tie-rods are pushed through the crankcase
from the right side of the crankcase except for the lower tie-rod
nearest the flywheel end of the crankcase (number 7 main bearing).
This tie-rod must be pushed through from the left side due to
interference of the starter driven gear shaft.
a. Remove thirteen cotter pins (3) and thirteen slotted nuts (4) from right side of crankcase.
Have helper hold slotted nuts on opposite side of crankcase as necessary to keep tie-rods
from turning while removing nuts. Discard cotter pins.
b. Remove six washer-plates (5) from right side of crankcase.
