M/T Shift Forks Clearance Inspection
NOTE: The synchro sleeve and synchro hub should be replaced as a set.
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 (0.014−0.026 in.)
Service Limit:
1.0 mm (0.04 in.)
Measure the thickness of the shift fork (A) fingers.
If the thickness of the shift fork finger is not within the standard, replace the shift fork with a new one.
If the thickness of the shift fork finger is within the standard, replace the synchro sleeve with a new one.
Standard:
1st/2nd, 3rd/4th shift forks:
7.4−7.6 mm (0.29−0.30 in.)
5th shift fork:
6.7−6.9 mm (0.26−0.27 in.)
Measure the clearance between the shift forks (A) and the shift arm (B). If the clearance exceeds the service limit, go to
Step 4
.
Standard:
0.2−0.5 mm (0.008−0.020 in.)
Service Limit:
0.62 mm (0.024 in.)
Measure the width of the shift arm (A).
If the width of the shift arm is not within the standard, replace the shift arm with a new one.
If the width of the shift arm is within the standard, replace the shift fork or shift piece with a new one.
Standard:
12.9−13.0 mm (0.508−0.512 in.)
