NOTE: To replace crankshaft bearings,
use the Arctic Bearing Puller Kit (pin
0144-080) to remove the bearings. To install a
bearing, squirt oil into the bearing; then using a
propane torch, heat the inner race of the bear·
ing (until slight smoke is noted coming from the
bearing) and slide it onto the crankshaft mak-
ing sure the dowel-pin hole in the outer race is
properly positioned and will align with its hole
in the crankcase.
