10-Rib Idler Pulley lying around?
 

Looking for one....with bearing installed ideally. Diameter unimportant.

Thanks!

There not that expensive, just look at the Dayco catalog and pic which will work
example :
17MM ID = 89108 $16.00 and is plastic , or 89117 is steel $60.00 (could be cheaper at other places
