DISASSEMBLY

PROCEDURE

1. INSPECT 3RD GEAR THRUST CLEARANCE

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

Standard clearance:

0.200 to 0.490 mm (0.0079 to 0.0192 in.)

If the clearance is outside the specification, replace the 3rd gear, thrust washer, clutch hub or shaft.

HINT:

Replace the part or parts determined to be the most likely cause of the problem.

2. INSPECT 3RD GEAR RADIAL CLEARANCE

(a) Using a dial indicator, measure the 3rd gear radial clearance.

Standard clearance:

0.0150 to 0.065 mm (0.0006 to 0.0025 in.)

If the clearance is outside the specification, replace the 3rd gear, 3rd gear needle roller bearing or shaft.

HINT:

Replace the part or parts determined to be the most likely cause of the problem.

3. INSPECT 6TH GEAR SUB-ASSEMBLY THRUST CLEARANCE

(a) Using a feeler gauge, measure the 6th gear sub-assembly thrust clearance.

Standard clearance:

0.150 to 0.580 mm (0.0059 to 0.0228 in.)

If the clearance is outside the specification, replace the 6th gear sub-assembly, thrust washer, clutch hub or shaft.

HINT:

Replace the part or parts determined to be the most likely cause of the problem.

4. INSPECT 6TH GEAR SUB-ASSEMBLY RADIAL CLEARANCE

(a) Using a dial indicator, measure the 6th gear sub-assembly radial clearance.

Standard clearance:

0.015 to 0.067 mm (0.0006 to 0.0026 in.)

If the clearance is outside the specification, replace the 6th gear sub-assembly, 6th gear needle roller bearing or shaft.

HINT:

Replace the part or parts determined to be the most likely cause of the problem.

5. INSPECT 5TH GEAR THRUST CLEARANCE

(a) Using a feeler gauge, measure the 5th gear thrust clearance.

Standard clearance:

0.150 to 0.410 mm (0.0059 to 0.0161 in.)

If the clearance is outside the specification, replace the 6th gear sub-assembly, 6th gear needle roller bearing or shaft.

HINT:

Replace the part or parts determined to be the most likely cause of the problem.

6. INSPECT 5TH GEAR RADIAL CLEARANCE

(a) Using a dial indicator, measure the 5th gear radial clearance.

Standard clearance:

0.013 to 0.054 mm (0.0006 to 0.0021 in.)

If the clearance is outside the specification, replace the 5th gear, thrust washer, clutch hub or shaft.

HINT:

Replace the part or parts determined to be the most likely cause of the problem.

7. REMOVE NO. 2 CLUTCH HUB SETTING SHAFT SNAP RING
