You may have to purchase the belt from a Precor dealer in you area, if you don't have one then call Precor directly @ 1-800-347-4404 and they will help you. Most of these part have not hit the secondary market yet and Precor pretty much call the shots.

You use the two bolts that hold the step up pulley in place. The step up pulley is the pulley assembly that is closes to the back of the unit. The step up pulley slides into two grooves in the frame, then there is a bolt on each side that run down the groove into the step up pulley. These bolts are the bolts that adjust the tension for the skinny belt. You may need to loosen the other belt first then tighten the skinny then retighten the belt you replaced.

There is a place on line to get some of these, it is. www.treadmilldoctor.com/Products-Services2/precor-treadmill-belt.
The manual can be found at. fitness.manualsonline.com/ex/thread/view/idThread/2141832
This place has manuals and user manulas along with support and some partswww.shopwiki.com/Precor+EFX+5.171 I believe this unit has a 10 yr warranty with it and the part in question may be covered by them. There is also a 1 year part warrant for other parts, I just don't know what parts they are covering for the 10 yr.

How to repair a 546 efx precor

Assuming the buttons are working, the numbers change on the display, and the incline works, it may be the lower circuit board or the generator. If it is a very old unit, it may be the electromagnet or the data cable that connects the two circuit boards.

Whenever I use our eliptical precor efx, as soon as the elevation starts it says error 45

Precor Error 45, Lift Moving in Wrong Direction Probable Cause 1. Lift motor hysteresis.
2. Lower PCA is bad.
Corrective Action 1. The error would usually occur when the lift was already in motion (usually downward) when a lift command in the opposite direction (upward) was made. Some lift motors used in production exhibited a very long turnaround time and the lift motor would still be moving in the original commanded direction while the control system was trying to move the lift in the opposite commanded direction. If the error continues to re-occur, replace the lift motor.
2. It is a rare condition, however if the lift moves in the opposite direction commanded, replace the lower PCA.
