Komatsu Track Adjusters

DuraTrack track adjusters for Komatsu excavators, listed by machine model

The track adjuster, also called the track tensioner or recoil spring assembly, sits in the undercarriage frame between the bulkhead and the idler and keeps the track correctly tensioned. DuraTrack track adjusters are listed for Komatsu models including PC100-6, PC118MR-8, PC130-8, PC138US-11, PC160LC-8, PC180LC-7, PC200-8, PC210LC-11, PC220-8 and PC228USLC-8.

Each assembly combines a grease-filled tensioning piston that sets the tension when grease is pumped through the nipple, a spring pack that absorbs impact as the track meets obstacles, and a yoke that bolts to the idler side arms. All DuraTrack track adjusters are manufactured to OEM specification and inspected throughout manufacture to ensure correct fitment and performance.

Track adjusters carry a 12 month warranty when purchased and fitted with a new idler, and 6 months when fitted without one, because a worn idler can cause a new adjuster to fail prematurely. It is also far easier to replace the adjuster while the idler is being changed.

Order before 4:30pm for next working day UK delivery on stocked assemblies. A track that looks far too tight can mean the spring rod has broken; loss of tension points to failed piston seals.
