CAT Idlers

DuraTrack idlers for CAT 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 CAT models including 259B3, 301.5, 304 Next Gen, 307, 311C U, 313 GC Next Gen, 315 Next Gen, 318C DAH, 320D and 322D. See also: CAT track adjusters, CAT sprockets.

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. Track adjusters carry a 12 month warranty when purchased and fitted with a new idler, and 6 months when fitted without one.

Order before 4:30pm for next working day UK delivery on stocked assemblies. 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. Send the machine model and serial number to the team, or browse all idlers and the wider DuraTrack undercarriage range.
