Frequently Asked Questions

What does an engine belt tensioner do on a John Deere forestry machine?

The belt tensioner maintains proper tension on the serpentine and accessory drive belts so the belt does not slip or wear prematurely. A worn or weak tensioner can cause belt squeal, uneven wear, and loss of drive to accessories. Broken Tractor carries belt tensioners, idler rollers, and fan support brackets for John Deere forestry machines.

How do I know if the RE505265 idler roller fits my John Deere forestry machine?

The RE505265 idler roller fits a range of John Deere forestry models including the 1710D, 1711D, 1910E, 753JH, 803MH, 853JH, 853MH, 859MH, 903JH, 903MH, 909JH, 909KH, 909MH, and 953MH. Because fitment can depend on engine and serial range, confirm by matching the part number to your machine before ordering. Our parts team can help verify the correct unit.

What is included with the John Deere fan support bracket RE503664?

The RE503664 is an engine fan support bracket that comes with the hub. It fits several John Deere forestry models including the 653G, 1010D, 1070D, 1110D, 1410D, 1490, and 1490D. Confirm fitment by engine and serial range before ordering.

Should I replace or repair a worn belt tensioner on a John Deere skidder?

A worn tensioner is usually replaced rather than repaired, since the spring and pulley bearing wear as a unit and cause belt slip when they weaken. Broken Tractor offers new and quality aftermarket belt tensioners that fit John Deere forestry skidders and forwarders such as the 530B, 560D, 1270D, and 1470D. Match the part number or confirm fitment before ordering.
