    • Use a 7/16" socket and socket wrench to remove the center pulley bolt.

    • The bolt can be heavily thread-locked in place, and the bolt head can shear off easily. To prevent breakage, use a torch and heat the bolt for two minutes to weaken the thread-lock.

    • Your pulley may be loose enough to remove by hand. If not, follow this step to use the gear puller to remove the pulley.

    • Attach a gear puller to the pulley.

    • If your gear puller's center pin is too thick for the pulley, use a 1/2" socket as a buffer.

    • Crank on the gear puller with a wrench to remove the pulley.

    • Re-assembly tips:

    • Lubricate the axle and key with machine oil.

    • Set the square key in the pulley first, then align the pulley onto the axle. This makes it slightly easier to hammer the pulley in place.

    • Hammer the pulley in place with a rubber mallet.

    • Before you tighten the set screws, make sure that the drive pulley's belt path aligns with the idler pulley.
