Disassembly of Input Shaft Assembly

1. INSPECT 3RD AND 4TH GEAR THRUST CLEARANCE
Using a feeler gauge, measure the thrust clearance.

Standard clearance:
3rd gear 0.10 - 0.35 mm (0.0039 - 0.0138 in.)
4th gear 0.10 - 0.55 mm (0.0039 - 0.0217 in.)

Maximum clearance:
3rd gear 0.40 mm (0.0157 in.)
4th gear 0.60 mm (0.0236 in.)




2. INSPECT 3RD AND 4TH GEAR RADIAL CLEARANCE
Using dial indicator, measure the radial clearance between the gear and shaft.

Standard clearance: 0.015 - 0.058 mm (0.0006 - 0.0023 in.)
Maximum clearance: 0.070 mm (0.0028 in.)

If the clearance exceeds the maximum, replace the gear, needle roller bearing or shaft.
