M/T Shift Forks Clearance Inspection

NOTE: The synchro sleeve and synchro hub should be replaced as a set.

1.Measure the clearance between each shift fork (A) and its matching synchro sleeve (B). If the clearance exceeds the service limit, go to 2.

Standard: 0.35-0.65 mm (0.014-0.026 in.) 
Service Limit: 1.0 mm (0.039 in.) 

 

2.Measure the thickness of the shift fork 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: 7.4-7.6 mm (0.29-0.30 in.) 

 

3.Measure the clearance between the shift fork (A) and the shift arm (B). If the clearance exceeds the service limit, go to 4.

Standard: 0.2-0.5 mm (0.008-0.020 in.) 
Service Limit: 0.60 mm (0.023 in.) 

 

4.Measure the width of the shift arm.

  • 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: 16.9-17.0 mm (0.665-0.669 in.)
