DISASSEMBLY

PROCEDURE

1. INSPECT COUNTERSHAFT REVERSE GEAR THRUST CLEARANCE

(a) Using a dial indicator, measure the countershaft reverse gear thrust clearance.

Standard clearance:

0.150 to 0.300 mm (0.0060 to 0.0118 in.)

If the clearance is outside the specification, replace the countershaft reverse gear, reverse gear bearing inner race or No. 4 transmission clutch hub.

HINT:

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

2. INSPECT COUNTERSHAFT REVERSE GEAR RADIAL CLEARANCE

(a) Using a dial indicator, measure the countershaft reverse gear radial clearance.

Standard clearance:

0.015 to 0.065 mm (0.0006 to 0.0026 in.)

If the clearance is outside the specification, replace the countershaft reverse gear, reverse gear bearing inner race or needle roller bearing.

HINT:

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

3. INSPECT COUNTERSHAFT 1ST SPEED GEAR THRUST CLEARANCE

(a) Using a dial indicator, measure the countershaft 1st speed gear thrust clearance.

Standard clearance:

0.150 to 0.480 mm (0.0060 to 0.0188 in.)

If the clearance is outside the specification, replace the countershaft 1st speed gear, clutch hub or counter gear.

HINT:

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

4. INSPECT COUNTERSHAFT 1ST SPEED GEAR RADIAL CLEARANCE

(a) Using a dial indicator, measure the countershaft 1st speed gear 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 countershaft 1st speed gear, 1st gear needle roller bearing or shaft.

HINT:

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

5. INSPECT COUNTERSHAFT 2ND SPEED GEAR THRUST CLEARANCE

(a) Using a dial indicator, measure the countershaft 2nd speed gear thrust clearance.

Standard clearance:

0.150 to 0.480 mm (0.0060 to 0.0188 in.)

If the clearance is outside the specification, replace the countershaft 2nd speed gear, clutch hub or counter gear.

HINT:

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

6. INSPECT COUNTERSHAFT 2ND SPEED GEAR RADIAL CLEARANCE

(a) Using a dial indicator, measure the countershaft 2nd speed gear 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 countershaft 2nd speed gear, 2nd gear needle roller bearing or shaft.

HINT:

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

7. REMOVE REAR COUNTER GEAR BEARING SNAP RING

(a) Using a snap ring expander, remove the rear counter gear bearing snap ring from the counter gear.

8. REMOVE REAR COUNTER GEAR BEARING OR ROLLER

(a) Using SST, remove the rear counter gear bearing or roller (inner races) from the counter gear.
