Replacement right crank assembly fits certain BowFlex Max Trainer models and serial#s.

The included hardware is a nut, large washer, bolt and small washer. The nut and large washer go on the shaft that fits through the square hole in the crank arm.

The bolt and small washer work for the leg assembly connection to the crank arm.
If included, the shoulder washer fits where the connector arm and pivot arm join together.
