Thought I would chime in on this ancient biblical thread as I too, am having the same problem
Its a 2013 Supercharged ROUSH Off Road with 56,000 miles....Ive done about 1500 of those since I purchased it so I have no real history on the truck
Belt keeps jumping off
Seeing as all the information is a few years old (from what Ive read on posts from this forum) I was wondering if there has been any more advancements on the THUMPER belt tensioner (
www.thumpracing.com ....and can some one tell me if there is any more updates on a replacement serpentine belt for a Supercharged 2013 Roush Raptor?
From what I have read on here, is that O'Rieleys stock a belt (Part# K061251 Gates Century Series Micro-V - V-Ribbed Belt)
UPC: 770075355106
Number Of Ribs: 6
Width (In): 0.807 Inch
Outside Circumference (In): 125.660 Inch
Gates Century Series Micro-V K061251 - V-Ribbed Belt | O'Reilly Auto Parts
A factory ROUSH belt is 3200mm long where as the Gates belt is a little smaller however everyone says they fit but need some love
So my question is, has anyone got an update on replacement belts (non ROUSH) and do we have any more reviews on the THUMPER idler as Im thinking of ordering a gates belt today to try it out
Thanks in Advance
Matt
