Reliable Quality

These double flanged idlers 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. Our parts come backed up by a factory warranty so you can buy them online with confidence.

Usually when your track starts sagging machine operators may think the track is just stretched out. So then just go buy a new track, right? WRONG! MAKE SURE YOU CHECK ALL UNDERCARRIAGE PARTS!! It's very likely that the sprocket and idler are worn out which is preventing proper tensioning. Not replacing these parts will shorten the life of the track. If you have questions about your idler, give us a call and we will be more than happy to help out.

Cat 249D Rubber Track Fitment FAQ

The tracks on a Cat 249D are available in 13-inch wide 320x86x49 and 16-inch wide 400x86x49.

Rubber tracks on Cat 249D track loaders can last months or years depending on several factors. If you replace all of the worn undercarriage parts at the same time you install your rubber tracks then the lifespan will be increased up to 20% compared to installing tracks on worn sprockets. If your Cat track loader operator is carefully making decisions on the job site and limiting high-speed travel while avoiding curbs and debris, that will significantly increase the lifespan of your rubber tracks.
