Is your 760 not tracking well?  Do the belts seem to have a mind of their own?  If so this replacement idler wheel might be the part to make your machine track like new again.

The 707EX comes complete with bearings and a hardened shaft. 

The 707EX idler wheel is covered with a urethane coating that has been shown to last 30% longer than standard aluminum wheels.  The urethane also reduces friction making the idlers run cooler.
