Precor C954 Serivce Manual page 63

Place the drive belt on the new drive roller and use as a handle to slide the drive roller through the
6.
running belt and into place. Hand tighten both drive roller mounting bolts.
7. 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.
8. 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
bracket. Using a measuring tape, measure the distance from the front of the left side drive roller
shaft to the front of the frame cross beam and make note of that measurement. Tighten the right
side drive roller bolt until it measures the same distance as the left side drive roller, shaft to frame.
This will ensure that the drive roller is parallel and square to the front of the frame.
