Drive Belt Replacement - Precor TRM10/GEN06 Service Manual

Drive Belt 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. Improper tensioning of 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 Loosen, but do not remove the take up roller mounting bolts. These
bolts are being loosened to remove the tension on the running belt.
4 Walk the drive belt off the motor pulley.
5 Remove both drive roller mounting bolts evenly, releasing the tension.
Remove the drive roller from the treadmill using the drive belt as a
handle.
6 Place the new drive belt on the drive roller and use the drive belt as
a handle to slide the drive roller through the 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.
9 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.
10 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.
