What Does a Track Adjuster Grease Valve Do?
The track adjuster grease valve sits on the adjuster cylinder next to the idler. Pumping grease through it with a grease gun pushes the idler out and tightens the track; loosening the valve slowly releases grease and slackens the track. If the valve leaks, the track loses tension and wear increases.
Signs the Valve Needs Replacing
- Track losing tension: a track that sags again soon after adjusting.
- Grease leaking at the valve: grease around the valve or adjuster means the valve is not sealing.
- Track will not tighten or loosen: a damaged valve may not take grease or release it.
These symptoms overlap with worn pumps, dirty oil and clogged filters, so check the basics and measure pressure before replacing the valve.
How to Order and Install the EX-C25009 Grease Valve
- Confirm your machine model, engine model and the part number on your existing valve before ordering.
- Send a photo of the nameplate or the old valve if you are not sure; LIONKITS will confirm fitment for you.
- Release grease only by loosening the valve slowly, about one turn, and never remove the valve or the grease fitting completely: the grease inside is under very high pressure.
- Stand clear of the valve while loosening it and wear eye protection.
- Tighten the valve to the torque in the service manual once the track sag is correct, then move the machine back and forth and recheck the sag.
