OUTPUT SHAFT INSPECTION

PROCEDURE

1. INSPECT 1ST GEAR THRUST CLEARANCE

   
   

   1. 

      Using a dial indicator, measure the 1st gear thrust clearance.

      Standard clearance
      0.20 to 0.38 mm (0.00788 to 0.0149 in.)

      Maximum clearance
      0.38 mm (0.0149 in.)

      If the clearance is more than the maximum, replace the No. 1 transmission clutch hub, 1st gear bush or 1st gear. Replace the part or parts determined to be the most likely cause of the problem.

2. INSPECT 2ND GEAR THRUST CLEARANCE

   
   

   1. 

      Using a dial indicator, measure the 2nd gear thrust clearance.

      Standard clearance
      0.15 to 0.33 mm (0.00591 to 0.0129 in.)

      Maximum clearance
      0.33 mm (0.0129 in.)

      If the clearance is more than the maximum, replace the inner 2nd gear bearing race, No. 1 transmission clutch hub, 2nd gear or 3rd driven gear. Replace the part or parts determined to be the most likely cause of the problem.

3. INSPECT 1ST GEAR RADIAL CLEARANCE

   
   

   1. 

      Using a dial indicator, measure the 1st gear radial clearance.

      Standard clearance

      Maximum clearance
      0.045 mm (0.00177 in.)

      If the clearance is more than the maximum, replace the 1st gear, 1st gear needle roller bearing or output shaft. Replace the part or parts determined to be the most likely cause of the problem.

4. INSPECT 2ND GEAR RADIAL CLEARANCE

   
   

   1. 

      Using a dial indicator, measure the 2nd gear radial clearance.

      Maximum clearance
      0.045 mm (0.00177 in.)

      If the clearance is more than the maximum, replace the 2nd gear, 2nd gear needle roller bearing or output shaft. Replace the part or parts determined to be the most likely cause of the problem.
