Disassembly

1. INSPECT 1ST GEAR THRUST CLEARANCE

(a) Using a feeler gauge, measure the 1st gear thrust clearance.

Standard clearance:

0.10 to 0.40 mm (0.0039 to 0.0157 in.) Maximum clearance: 0.40 mm (0.0157 in.)

If the clearance exceeds the maximum, replace the 1st gear thrust washer, 1st gear or transmission clutch hub No. 1.

2. INSPECT 2ND GEAR THRUST CLEARANCE

(a) Using a dial gauge, measure the 2nd gear thrust clearance.

Standard clearance:

0.10 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. 1, 2nd gear or 3rd driven gear.

3. INSPECT 1ST GEAR RADIAL CLEARANCE

(a) Using a dial gauge, measure the 1st 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 1st gear or 1st gear needle roller bearing.

4. INSPECT 2ND GEAR RADIAL CLEARANCE

(a) Using a dial gauge, measure the 2nd gear radial clearance between the gear and shaft. Standard clearance: KOYO made:

0.015 to 0.058 mm (0.0006 to 0.0023 in.) NSK made: 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 2nd gear or 2nd gear needle roller bearing.
