INSPECTION OF REAR OUTPUT SHAFT ASSEMBLY
1.
INSPECT REAR OUTPUT SHAFT
Using a micrometer, measure the outer diameter of the
rear output shaft journal surface.
Minimum diameter:
Part A 27.98 mm (1.1016 in.)
B 36.98 mm (1.4559 in.)
2.
CHECK OIL CLEARANCE OF DRIVE SPROCKET
Using a dial indicator, measure the oil clearance between
the sprocket and shaft with the needle roller bearing
installed.
Standard clearance: 0.010 − 0.055 mm
(0.0004 − 0.0022 in.)
Maximum clearance: 0.055 mm (0.0022 in.)
If the clearance exceeds the limit, replace the drive
sprocket, rear output shaft or needle roller bearing.
3.
MEASURE CLEARANCE OF FRONT DRIVE SHAFT
FORK AND HUB SLEEVE
Using a feeler gauge, measure the clearance between the
front drive shaft fork and hub sleeve.
Maximum clearance: 1.0 mm (0.039 in.)
If the clearance exceeds the limit, replace the shift fork or
hub sleeve.
4.
MEASURE CLEARANCE OF HIGH AND LOW SHIFT
FORK AND HUB SLEEVE
Using a feeler gauge, measure the clearance between
the high and low shift fork and hub sleeve.
Maximum clearance: 1.0 mm (0.039 in.)
If the clearance exceeds the limit, replace the shift fork
or hub sleeve.
