The PC210LC-10 Excavator Track Adjuster Assembly is an important undercarriage component designed to maintain proper track tension and support stable crawler operation. Installed between the front idler and track-frame system, the track adjuster works with the recoil spring mechanism to absorb shock loads and maintain appropriate tension as the excavator operates on uneven or demanding terrain.

Komatsu specifications for the PC210LC-10 confirm the use of hydraulic track adjusters on each side of the undercarriage. Aftermarket parts references identify 20Y-30-42270, 206-30-00090, and 206-30-00091 as compatible track-adjuster or recoil-spring assembly references for PC210LC-10 applications.

A properly functioning track adjuster helps maintain consistent track tension, reducing excessive track movement and helping protect other undercarriage components such as the front idler, track chain and rollers. It is therefore an important replacement component when the existing adjuster is damaged, leaking, seized, or unable to maintain correct track tension.
