Clean the accessory drive parts with clean fuel oil and dry them with compressed air. Examine the gear teeth
of the drive shaft, drive coupling, drive hub or drive plate for wear. If worn excessively, replace them with new
parts.
Inspect the ball bearing used to support the accessory drive shaft shown in Fig. 6. Wash the bearing in clean
fuel oil and dry it with compressed air. Shielded bearings must not be washed; dirt may be washed in and the
cleaning fluid could not be entirely removed
