Shift Fork Clearance - Inspect
1st/2nd, 3rd/4th, 5th/6th
Reverse
1.
Measure the clearance between each shift fork (A) and its matching synchro sleeve (B). If the clearance exceeds the service limit, go to step 2.
Standard:
0.35?0.65 mm
(0.014?0.025 in)
Service Limit:
0.65 mm (0.025 in)
2.
Measure the thickness of the shift fork fingers.
If the thickness is not within the standard, replace the shift fork.
If the thickness is within the standard, replace the synchro sleeve and the synchro hub as a set.
If one arm of the shift fork shows more wear than others, the fork may be bent and needs to be replaced.
1st/2nd, 3rd/4th, 5th/6th
Standard:
7.4?7.6 mm (0.291?0.299 in)
Reverse
Standard:
6.2?6.4 mm (0.244?0.252 in)
3.
Measure the clearance between each shift fork (A) and the shift piece (B). If the clearance exceeds the service limit, go to step 4.
Standard:
0.2?0.6 mm (0.008?0.024 in)
Service Limit:
0.6 mm (0.024 in)
4.
Measure the width of the shift piece.
If the width is not within the standard, replace the shift piece.
If the width is within the standard, replace the shift fork or the reverse shift piece.
Standard:
12.8?13.0 mm (0.504?0.512 in)
