What Does This Track Cylinder / Piston / Rod Nut / Flange Do?

The track adjuster cylinder uses grease or hydraulic pressure to tension the track chain via the front idler, maintaining the correct sag for safe operation. The piston, rod nut, and flanges are the internal and external sealing and retention components of the cylinder assembly.

Possible Track Cylinder / Piston / Rod Nut / Flange Problem Symptoms

If your machine is showing any of the following, a faulty track cylinder / piston / rod nut / flange may be the cause:

  • Track sagging excessively and slipping off the sprocket or idler under load
  • Track too tight, causing accelerated wear on the undercarriage components
  • Grease leaking from the track adjuster cylinder or valve body
  • Track tension not holding after adjustment — releasing slowly over a short operating period
