NOTE: The OWC mechanical diode is also the coast clutch pressure plate.

NOTE: Gas applications use a unique mechanical diode from diesel applications.

Inspect the OWC for cracks and damaged splines. When installed correctly the internal splined portion of the OWC should rotate counterclockwise and lock when rotated clockwise. If any damage is found or if it does not rotate in the correct direction, install a new OWC.

NOTE: Inspect all separator and friction plates for damage. If any damage is found to any of the plates install new friction and separator plates.

NOTE: When installing the one-way clutch (OWC) (mechanical diode) the words "this side up" should be visible.

Check the stack-up clearance.
- Using a feeler gauge, measure the stack-up clearance in three places, 120 degrees apart, between the snap ring and the coast clutch pressure plate.
- If the clearance is not within specification, install the correct coast clutch pressure plate retainer snap ring and recheck the clearance.
