motor pulley, one (1) of the tension bolts will need to be tightened. If the
belt is riding against the inside lip of the motor pulley, one (1) of the
tension bolts will need to be loosened. Each time an adjustment is made,
the flywheel needs to be spun to allow the belt to seat.
15. Once aligned the timing belt should appear taut. Tighten the bolts and
nuts at the base of the motor. The timing belt should have approximately
3/8” travel when pushed down and then pulled up on. If this is too tight,
loosen motor and back tension off the tension bolt closest to the front
roller and add an equal amount to the other tension bolt. Spin the flywheel
to allow the belt to seat and retighten motor bolts and nuts. If the timing
belt is too loose, add tension to the tension bolt closest to the front roller
and reduce tension by an equal amount on the other tension bolt. Spin
the flywheel to allow the belt to seat and retighten the motor. Repeat this
procedure until the tension is correct.
16. Verify speed sensor alignment. When the flywheel is rotated, the magnet
(P1599) in the flywheel should pass the center of the speed sensor
(P1522). The speed sensor can be adjusted by moving the slotted
bracket (A1598) forward or backward until the magnet passes the center
of the speed sensor. This adjustment requires a 7/16” socket and
extension to loosen and tighten the bolt holding the speed sensor bracket
in place.
I. Timing Belt Replacement
1. Elevate treadmill to 15% incline and turn off power to the unit.
2. Using a Philips screwdriver, remove the motor hood (P1252).
3. Use a 5/16” Allen wrench to turn each rear roller tension bolt,
counterclockwise, 6-10 full turns to release running belt pressure.
4. Remove the left, front roller bolt using a 9/16” wrench or socket.
5. Loosen the right, front roller bolt far enough to disengage bolt threads from
the roller threads.
