To replace a pulley:
1. Remove the jam nut using a 9/16” socket or wrench.
2. Use a two-legged wheel puller to pull the old pulley/bearing assembly forward and off the
shaft.
3. Clean the shaft and check that it is smooth. If it has any significant scratches, carefully work
them out with an abrasive pad or emery cloth.
4. Apply a thin layer of petroleum jelly to the shaft.
5. Slide the new pulley assembly onto the shaft. Gently tap with a soft mallet if necessary. DO
NOT HAMMER.
6. Replace the nut and tighten until there is no endplay, but not so tight as to bind the bearing.
After replacing a pulley, verify that it spins freely and does not wobble.
