PROPELLER SHAFT ASSEMBLY INSPECTION

PROCEDURE


  1. INSPECT FLEXIBLE COUPLING


    1. B000NZ2

      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 with center bearing shaft assembly.

  2. INSPECT PROPELLER SHAFT ASSEMBLY


    1. B000NVR

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

      Maximum Runout
      0.5 mm (0.0196 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. B000OOI

      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.
