Disassembly

1. INSPECT 4TH GEAR THRUST CLEARANCE

(a) Using a feeler gauge, measure the 4th gear thrust clearance.

Standard clearance:

0.1 to 0.55 mm (0.0039 to 0.0217 in.) Maximum clearance: 0.55 mm (0.0217 in.)

If the clearance exceeds the maximum, replace transmission clutch hub No. 2, the 4th gear or input shaft rear radial ball bearing.

2. INSPECT 3RD GEAR THRUST CLEARANCE

(a) Using a dial gauge, measure the 3rd gear thrust clearance.

Standard clearance:

0.1 to 0.35 mm (0.0039 to 0.0138 in.) Maximum clearance: 0.35 mm (0.0138 in.)

If the clearance exceeds the maximum, replace transmission clutch hub No. 2, the 3rd gear or input shaft.

3. INSPECT 4TH GEAR RADIAL CLEARANCE

(a) Using a dial indicator, measure the 4th gear radial clearance between the gear and shaft. Standard clearance:

0.009 to 0.050 mm (0.0004 to 0.0020 in.) Maximum clearance:

0.050 mm (0.0020 in.) If the clearance exceeds the maximum, replace the 4th gear, 4th gear needle roller bearing or input shaft.

4. INSPECT 3RD GEAR RADIAL CLEARANCE

(a) Using a dial gauge, measure the 3rd gear radial clearance between the gear and shaft. Standard clearance: KOYO made bearing:

0.015 to 0.058 mm (0.0006 to 0.0023 in.) NSK made bearing: 0.015 to 0.056 mm (0.0006 to 0.0022 in.) Maximum clearance: KOYO made:

0.058 mm (0.0023 in.) NSK made: 0.056 mm (0.0022 in.) If the clearance exceeds the maximum, replace the 3rd gear, 3rd gear needle roller bearing or input shaft.
