   INSPECT FLEXIBLE COUPLING

   
   
   1. 

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

   2. Inspect the flexible coupling centering bushings.

      Tip:

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

   INSPECT PROPELLER SHAFT ASSEMBLY

   
   
   1. 

      Using a dial indicator, measure the runout of the propeller with center bearing shaft assembly (front side).

      Maximum Runout
      0.4 mm (0.0157 in.)

      Note:
      

      • The dial indicator must be set at a right angle to the center of the propeller with center bearing shaft assembly (front side).

      • Make sure the V block does not interfere with the balance piece.

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

   2. 

      Using a dial indicator, measure the runout of the propeller with center bearing shaft assembly (rear side).

      Maximum Runout
      0.6 mm (0.0236 in.)

      Note:
      

      • The dial indicator must be set at a right angle to the center of the propeller with center bearing shaft assembly (rear side).

      • Make sure the V block does not interfere with the balance piece.

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