John Deere Idlers

DuraTrack idlers for John Deere excavators, compact track loaders and forestry machines, listed by machine model

The idler sits at the front of the track frame, guides the track links and, together with the track adjuster, keeps the chain at the correct tension. DuraTrack idler assemblies are listed for John Deere models including 17 ZTS, 27C ZTS, 50 ZTS, 75D, 120D, 160D LC, 210LCN, 290D, 319E and 330C.

Each DuraTrack idler is a cast assembly supplied complete with a heavy-duty seal group, shaft and brackets, manufactured to OEM specification in ISO 9001 approved facilities. The machine model and serial number identify the assembly, and the markings on the side of the old idler confirm the match.

Change the track adjuster at the same time where it is worn. A worn idler can cause a new track adjuster to fail prematurely, and the adjuster is far easier to replace while the idler is off. A track adjuster installed with a new idler carries a 12-month warranty; we confirm the term when we quote.

Held in US stock. Order by 4:00pm CT for same-day shipping on stocked assemblies. All DuraTrack components carry a minimum 12-month warranty as standard. Wide track shoes and digging over the sprockets both accelerate idler tread and flange wear, so have the idler measured against new dimensions before it is changed.
