PROPELLER SHAFT ASSEMBLY INSPECTION

PROCEDURE


  1. INSPECT FLEXIBLE COUPLING


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

    2. A000RGR

      Inspect the flexible coupling centering bushings.

      Tech Tips

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

  2. INSPECT PROPELLER INTERMEDIATE SHAFT ASSEMBLY


    1. A000RR7

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

      Maximum runout
      0.8 mm (0.0314 in.)

      Note

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

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

  3. INSPECT PROPELLER SHAFT ASSEMBLY


    1. A000QKT

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

      Maximum runout
      0.8 mm (0.0314 in.)

      Note

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

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

  4. INSPECT UNIVERSAL JOINT SPIDER ASSEMBLY


    1. A000MUY

      Check that the spider bearing rotates smoothly.

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

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

  5. INSPECT NO. 1 CENTER SUPPORT BEARING ASSEMBLY


    1. A000SNS

      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.
