INSPECT OF OUTPUT SHAFT ASSEMBLY
1. MEASURE EACH GEAR THRUST CLEARANCE
(a) Using a feeler garge, measure the thrust clearance of
1 st gear and 3rd gear.
(b) Using a dial indicator, measure the thrust clearance
of 2nd gear.
1st gear
Standard clearance:
Maximum clearance:
2nd and 3rd gear
Standard clearance:
Maximum clearance:
0.10 - 0.45 mm
(0.0039 - 0.0177 in.)
0.50 mm (0.0197in.)
0.10 - 0.25 mm
(0.0039 - 0.0098 in.)
0.30 mm (0.0118in.)
2. CHECK OIL CLEARANCE OF EACH GEAR
Using a dial indicator, measure the oil clearance between
the gear and shaft with the needle roller bearing installed.
1st gear
Standard clearance:
Maximum clearance:
2nd and 3rd gear
Standard clearance:
Maximum clearance:
0.020 - 0.073 mm
(0.0008 - 0.0029 in.)
0.16 mm (0.0063 in.)
0.015 - 0.068 mm
(0.0006 - 0.0027 in.)
0.16 mm (0.0063 in.)
If the clearance exceeds the limit, replace the gear, nee-
dle roller bearing or shaft.
3. INSPECT OUTPUT SHAFT
(a) Using a micrometer, measure the output shaft flange
thickness.
Minimum thickness: 4.70 mm (0.1850 in.)
(b) Using a micrometer, measure the outer diameter of
the output shaft journal.
Minimum diameter:
A 1 st gear 38.860 mm (1.5299 in.)
B 2nd gear 46.860 mm (1.8449 in.)
C 3rd gear 37.860 mm (1.4905 in.)
