Replacing The Drive Roller - Precor TRM10/GEN06 Service Manual

Replacing the Drive Roller

Note: Two running belt gauges, Precor part number 20007-101, are required. It is
important that this procedure be followed to maintain correct drive belt and running
belt tension. Improper tensioning of the belt will lead to premature running belt wear,
premature driver roller bearing failure and premature take up roller bearing failure.
Drive Roller Removal
1 Remove the end caps from the rear of treadmill to expose the take up
roller mounting bolts. Remove the treadmill's motor cover.
2 Remove the deck trim from both sides.
3 Loosen, but do not remove the take up roller mounting bolts. The bolts
are being loosened to remove tension from the running belt.
4 Slowly rotate the drive motor flywheel while pressing the drive belt
off of the motor pulley.
5 Remove both drive roller mounting bolts releasing the tension evenly
on both sides. Remove the drive roller from the treadmill using the
drive belt as a handle.
