Yanmar Parts

These single flange idler assemblies are made to original specifications and produced with high-quality double lip seals to lock dirt and debris out and lock the lubrication in for long-lasting service for your machine.

If your track is coming off the guide frequently then your tension idler has probably worn to the point where it cannot tension the track properly. Replacing your tension idler will solve that problem assuming your tensioner itself is still good. The idler comes complete as pictured. If you have any questions please give us a call.
