Mainshaft Assembly Clearance Inspection

13-25  

NOTE:

  • If replacement is required, always replace the synchro sleeve and hub as a set.

  1. Support the bearing inner race with a socket (A), and push down on the mainshaft (B).

    Standard:

0.06 - 0.16 mm

(0.002 - 0.006 in.)

Service Limit:

0.25 mm (0.010 in.)

  1. Measure the clearance between 2nd (C) and 3rd (D) gears with a feeler gauge (E).
  • If the clearance is more than the service limit, go to step 3.
  • If the clearance is within the service limit, go to step 4.

  1. Measure the thickness of 3rd gear.
  • If the thickness of 3rd gear is less than the service limit, replace 3rd gear with a new one.
  • If the thickness of 3rd gear is within the service limit, replace the 3rd/4th synchro hub with a new one.

Standard:

23.92 - 23.97 mm

(0.981 - 0.944 in.)

Service Limit:

23.80 mm (0.937 in.)

  1. Measure the clearance between 4th gear (A) and the distance collar (B) with a dial indicator (C). If the clearance is more than the service limit, go to step 5.

    Standard:

0.06 - 0.16 mm

(0.002 - 0.006 in.)

Service Limit:

0.25 mm (0.010 in.)

  1. Measure distance (1) on the distance collar.

  • If distance (1) is not within the standard, replace the distance collar with a new one.
  • If distance (1) is within the standard, go to step 6.

Standard:

24.03 - 24.08 mm

(0.946 - 0.947 in.)
