Countershaft Assembly Clearance Inspection

WARNING: This page is about a different variant/trim than selected.

NOTE: Before inspection, make sure the special bolt is tightened to the specified torque (see COUNTERSHAFT REASSEMBLY ).

Measure the clearance between 1st gear (A) and the countershaft reverse gear (B) with a dial indicator (C).
- If the clearance exceeds the service limit, go to step 2.
- If the clearance is within the service limit, go to step 4.
Standard: 0.04- 0.17 mm (0.0016- 0.0067 in)

Service Limit: 0.28 mm (0.0110 in)

Measure the length of the countershaft reverse gear as shown.
- If the length is not within the standard, replace the countershaft reverse gear.
- If the length is within the standard, go to step 3.
Standard: 23.03- 23.08 mm (0.9067- 0.9087 in)

Measure the thickness of 1st gear.
- If the thickness is less than the service limit, replace 1st gear.
- If the thickness within the service limit, replace the 1st/2nd synchro hub and the 1st/2nd synchro sleeve as a set.
Standard: 22.91- 22.99 mm (0.9020- 0.9051 in)

Service Limit: 22.86 mm (0.9000 in)

Measure the clearance between 2nd gear (A) and 3rd gear (B) with a feeler gauge (C). If the clearance exceeds the service limit, go to step 5.
Standard: 0.04- 0.17 mm (0.002- 0.006 in)

Service Limit: 0.28 mm (0.011 in)

Measure the length of the 2nd gear distance collar.
- If the length is not within the standard, replace the 2nd gear distance collar.
- If the length is within the standard, go to step 6.
Standard: 23.03- 23.08 mm (0.9067- 0.9087 in)

Measure the thickness of 2nd gear as shown.
- If the thickness is less than the service limit, replace 2nd gear.
- If the thickness is within the service limit, replace the 1st/2nd synchro hub and the 1st/2nd synchro sleeve as a set.
Standard: 22.91- 22.99 mm (0.9020- 0.9051 in)

Service Limit: 22.86 mm (0.9000 in)
