PROCEDURE
INSPECT FLEXIBLE COUPLING
Check the front and rear flexible couplings for cracks or damage.
Inspect the flexible coupling centering bushings.
Tech Tips
If a bushing is damaged, replace the propeller with center bearing shaft assembly.
INSPECT PROPELLER SHAFT ASSEMBLY
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.
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.
