3. Put the lockwasher (382) onto the shaft (122).
4. Thread the locknut (136) onto the shaft (122) and tighten it until it is snug.
5. Bend the tangs of the lockwasher into the slots of the locknut.
6. Put the bearing-retaining ring (361A) onto the shaft (122).
Make sure that the flat side of the ring is towards the bearing.
7. Coat the inner surfaces of the bearings with lubricant.

return groove. Failure to do so may result in oil-flow obstruction.
Make sure that the shaft rotates freely.
f) Install the outboard labyrinth oil-seal (332A) into the bearing housing (134).
Place the drain slots of the oil seal at the bottom position (6 o’clock).
Make sure that the edges of the keyway are free from burrs. To protect the O-ring, cover the
keyway lengthwise with a piece of electrical tape before you install the oil seal.
