Drive Roller Replacement

This procedure is to be used to replace a drive roller while maintaining the drive belt's original
tensioning and the running belt's original tension and tracking settings. Two running belt
gauges, Precor part number 20007-101, are required.
Over tensioning the belt will lead to premature running belt wear, premature driver roller
bearing failure and premature take up roller bearing failure.
1. Remove the end caps and belt guards from the rear of treadmill to expose the take up roller
mounting bolts.
Remove the treadmill's motor cover.
2. Loosen, but do not remove the take up roller mounting bolts. The bolts are being loosened to
remove tension from the running belt.
