Disassembling the lower case
1. Remove the needle bearing from the
lower case.
NOTE:
• Since the diameter of the passage in the
lower case and the diameter of the special
service tool

are both 40 mm (1.57 in),
the special service tool may not fit into the
lower case. In that case, use a special ser-
vice tool with a smaller diameter.
• Be sure to remove the reverse gear before
removing the needle bearing.
2. Remove the retainer and shim(s).
3. Remove the needle bearing from the
retainer.

teeth and dogs of the reverse gear.
Replace the pinion or reverse gear if

Checking the bearing
1. Check the bearings. Replace the bear-
ings if pitted or if there is rumbling.
Checking the drive shaft
1. Check the drive shaft. Replace the drive
shaft if bent or worn.

the drive shaft if above specification.
