Countershaft Assembly Clearance Inspection

NOTE: If replacement is required, always replace the synchro sleeve and hub as a set.
  1. Measure the clearance between 2nd gear (A) and the countershaft (B) with a dial indicator.
    • If the clearance is more than the service limit, go to step 2.
    • If the clearance is within the service limit, go to step  3.

    Standard: 0.04-0.17 mm {0.002-0.007 in.) 

    Service Limit: 0.3 mm (0.012 in.)

  2. Measure the thickness of 2nd gear.
    • 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 sleeve.

    Standard: 32.88-32.96 mm (1.294-1.298 in.) 

    Service Limit: 32.76 mm (1.290 in.)

  3. Measure the clearance between 1st gear (A) and the distance collar (B). with a dial indicator.
    • If the clearance is more than the service limit, go to step 4.
    • If the clearance is within the service limit, go to step  6.

    Standard: 

    2000-2003 models: 0.04-0.22 mm (0.002-0.009 in.) 

    2004-2008 models: 0.04-0.17 mm (0.002-0.007 in.) 

    Service Limit: 0.3 mm (0.012 in.)

  4. Measure distance (1) on the distance collar.
    • If distance (1) is not within the standard, replace the distance collar.
    • If distance (1) is within the standard, go to step 5.

    Standard: 28.03-28.08 mm (1.104-1.106 in.)

  5. Measure the thickness of 1st gear.
    • If the thickness is less than the service limit, replace 1st gear.
    • If the thickness is within the service limit, replace the 1st/2nd synchro hub and sleeve.

    Standard: 

    2000-2003 models: 31.18-31.26 mm (1.228-1.231 in.) 

    2004-2008 models: 27.88-27.96 mm (1.098-1.101 in.)

  6. Measure the clearance between reverse gear (A) and the distance collar (B) with a dial indicator. If the clearance is more than the service limit, go to step 7.

    Standard: 0.04-0.22 mm (0.002-0.009 in.) 

    Service Limit: 0.3 mm (0.012 in.)

  7. Measure distance (2) on the distance collar.
    • If distance (2) is not within the standard, replace the distance collar.
    • If distance (2) is within the standard, go to step 8.

    Standard: 25.53-25.58 mm (1.005-1.007 in.)

  8. Measure the thickness of reverse gear.
    • If the thickness is less than the service limit, replace reverse gear.
    • If the thickness is within the service limit, replace the reverse synchro hub and sleeve.

    Standard: 26.38-26.46 mm (1.039-1.042 in.)
