E: INSPECTION
Disassembled parts should be washed with clean-
ing solvent first, then inspected carefully.
1) Bearing
Replace the bearings in the following cases.
• When the bearing balls, outer races and inner
races are broken or rusty.
• When the bearing is worn.
• When the bearings fail to turn smoothly or emit
noise in rotation after gear oil lubrication.
• The ball bearing on the rear side of the drive pin-
ion shaft should be checked for smooth rotation be-
fore the drive pinion shaft assembly is
disassembled. In this case, because a preload is
working on the bearing, its rotation feels like it is
slightly dragging unlike other bearings.
• When bearing has other defects.
2) Bushing (each gear)
Replace the bushing in following cases.
• When the sliding surface is damaged or abnor-
mally worn.
• When the inner wall is abnormally worn.
3) Gear
Replace gears in the following cases.
• Replace the gear with new part if its tooth surfac-
es are broken, damaged or excessively worn.
• Correct or replace if the cone that contacts the
baulk ring is rough or damaged.
• Correct or replace if the inner surface or end face
is damaged.
