Procedure 6.16 - Take Up Roller Replacement
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. 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 or rear guard from the rear of the treadmill to expose the take up roller
mounting bolts. Remove the treadmill motor cover.
2. Remove the deck trim from both sides.
3. Walk the drive belt off the drive roller and motor pulleys.
4. Loosen, but do not remove the drive roller mounting bolts. Release the tension evenly on both
sides. These bolts are being loosened to remove the tension on the running belt.
5. If applicable, remove the rear roller guards located in the front of the take up roller.
6. Remove the take up roller mounting bolts by releasing the tension evenly on both sides. Then lift
and slide the take up roller out.
7. Slide the new take up roller through the running belt and into place. Hand tighten both take
up roller mounting bolts a few turns only.
8. Make sure the running belt is in the center of the deck, the spacing should be the same on each
side of the running belt to the edge of the running deck.
9. Start tightening the left and right side drive roller mounting bolts. Move back and forth between
the left and right side mounting bolts so the bolts will tension evenly which will reduce the stress
on the threads of the bolts. The left side drive roller shaft will tighten flush to the front frame
