Begin by inspecting around the machine for any hardware that may have fallen out of the machine. Next remove the rear shroud, and inspect the upper, or drive, pulley. A flashlight may be needed. Note the pulley screws, which can be seen protruding from the back of the pulley. By manipulating the foot pedals the pulley will rotate, allowing the ability to check all four screws.

* Note whether all four screws are in place.

* Note whether all screws stick out about the same distance.

* Check that the belt is in place, and is not visibly damaged.

* Attempt to wiggle the pulley towards and away from the mast.

* Observe whether the pulley wobbles as it rotates.

After inspection, proceed with the troubleshooting steps in order.

Crank Puller: A Crank Puller is required to replace the drive pulley.

Has the Upper Pulley already been replaced recently?

NO YES Contact Customer Care for Advanced Troubleshooting Is the drive belt in place around the pulley?

YES NO Replace the Drive Belt and install the Drive Pulley Kit.
