Cooling Fan Pulley Tensioner Kit 6662997

Great product except for my application the main bolt, its' shoulder was a hair short, causing the Tensioner to back out as it moved. I installed a washer (included) on the back side which corrected that.

This is a perfect match for the part I needed installed easily quick delivery delivery

Working good

Terrible quality spring broke I 1 hour of running

No problem fit great a lot cheaper than the dealer

Part worked great on my bobcat 863 with the duetz oil cooled engine !

I can’t comment on longevity but I was able to get my skid steer loader running again using the new tensioner. I bought a 41” fan belt and got this thing installed within 15 minutes. I did not use the accessories, only the pully arm, spring, pully and bolts.

Units shoulder bolt was to short to reach thru arm assy. Had to add spacer to make up the different' s.Shoulder bolt threads had to be dressed to make fit 3/8- 16 threaded hole.Arm assy. doesn't have a bushing installed, shoulder bolt rides on alum arm.Had to install my own bushing.If I was not a machinist I would have sent back.4 stars as there was just enough material to get me back up and running.would not buy again
