Replacing The Take-Up Roller; Procedure - Precor Energy Series Service Manual

Replacing the Take-Up Roller

This procedure is to be used to replace a Take-up roller while maintaining the running belt's
original tension and tracking settings. Two running belt gauges, Precor part number 20007-101,
are required. It is important that this procedure be followed to maintain correct running belt
tension. When tension is removed from the running belt, the belt requires 24 hours for it to "relax".
If tension is removed from the belt and then re-tensioned without following this procedure or
allowing a 24 hour relaxation period, the running belt may be over tensioned. Over tensioning the
belt will lead to premature running belt wear, premature driver roller bearing failure and premature
Take-up roller bearing failure.

Procedure

1. Place two running belt gauges on each side of the running belt, being sure that the gauges are
not across a belt seam. Set the gauges to the 3% mark as shown in the Illustration below.
2. Once set the belt gauges cannot be disturbed or moved, doing so will invalidate the tension
settings and necessitate a 24 hour relaxation period before the running belt can be re-
tensioned.
3. Remove the end caps from the rear of treadmill to expose the Take-up roller mounting bolts.
4. Remove the left and right Take-up roller mounting bolts. The belt gauge readings will decrease
as the Take-up roller mounting bolts are removed. Remove the Take-up roller from the
treadmill.
5. Slide the replacement Take-up roller into the running belt and set it in its mounting position.
6. Hand start both Take-up roller mounting bolts.
7. Alternate tightening the two Take-up roller mounting bolts, in order to tighten both ends evenly,
until both running belt gauges again read exactly 3%.
8. When both gauges again read 3% the belt is at its original tension. It will now be necessary to
