Upper (Drive) Pulley - Bowflex Max Trainer M6 Service Manual

Upper (Drive) Pulley

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.
NOTE: It is OK if the threads in the
flange are damaged. The new
hardware includes nuts to securely
hold pulley in place.

the cause of the
