PROPELLER SHAFT ASSEMBLY INSPECTION

PROCEDURE

1. INSPECT FLEXIBLE COUPLING

   
   

   1. 

      Check the front and rear flexible couplings for cracks or damage.

   2. Inspect the flexible coupling centering bushings.

      Tech Tips

      If a bushing is damaged, replace the propeller shaft with center bearing assembly.

2. INSPECT PROPELLER INTERMEDIATE SHAFT ASSEMBLY

   
   

   1. 

      Using a dial indicator, measure the runout of the propeller intermediate shaft assembly.

      Maximum Runout
      0.8 mm (0.0315 in.)

      Note

      The dial indicator must be set at a right angle to the center of the propeller intermediate shaft assembly.

      If the shaft runout exceeds the maximum, replace the propeller shaft with center bearing assembly.

3. INSPECT PROPELLER SHAFT ASSEMBLY

   
   

   1. 

      Using a dial indicator, measure the runout of the propeller shaft assembly.

      Maximum Runout
      0.8 mm (0.0315 in.)

      Note

      The dial indicator must be set at a right angle to the center of the propeller shaft assembly.

      If the shaft runout exceeds the maximum, replace the propeller shaft with center bearing assembly.

4. INSPECT UNIVERSAL JOINT SPIDER ASSEMBLY

   
   

   1. 

      Check that the spider bearing rotates smoothly.

   2. Check that there is no play in the spider bearing.

      If necessary, replace the propeller shaft with center bearing assembly.

5. INSPECT NO. 1 CENTER SUPPORT BEARING ASSEMBLY

   
   

   1. 

      Turn the center support bearing by hand in the rotating direction.

   2. Check that the center support bearing turns smoothly, and check that the seals are not cracked or damaged.

      If the center support bearing is damaged or worn, or does not turn smoothly, replace it.
