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 on whom the sell parts and support to.
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.
