Track Adjuster – Maintenance & Installation Precautions

2026-04-03

Park on level ground and lower the attachment (blade/Bucket) to the ground before starting any work.
Relieve track tension completely by slowly loosening the grease valve (grease-type) or releasing hydraulic pressure (hydraulic-type) – never stand in front of the valve.
Use proper lifting equipment – track adjusters are heavy; use a hoist or jack with adequate capacity.

Mark alignment of the adjuster components before disassembly to aid correct reassembly.
Inspect for:
- Bent or scored cylinder rod.
- Worn seals, cracks, or corrosion.
- Damaged grease fitting or relief valve.
Replace seals as a set – never reuse old seals after disassembly.

Clean all parts thoroughly before assembly – dirt will destroy new seals immediately.
Lubricate seals and threads with clean hydraulic oil or recommended grease to prevent damage during assembly.
Align the adjuster correctly with the track frame and IDLER bracket – misalignment will cause premature failure.
Tighten mounting Bolts to manufacturer’s torque specification – use a torque wrench.
Bleed air from a hydraulic-type adjuster according to the service manual.

Pressurize slowly – for grease-type, pump grease gradually and stop immediately if abnormal resistance is felt.
Check for leaks – operate the track slowly and inspect around seals and fittings.
Adjust track sag to factory specification (too tight → wear/damage; too loose → derailing).
Re-torque bolts after initial operation (heat/vibration can loosen them).

Capture and dispose of old grease/hydraulic oil properly – do not release into soil or water.
Worn seals and scrap parts – follow local regulations for disposal.
