Case compact track loaders use the same undercarriage parts on the majority of their models from the CT420 through the TV450. Here is the aftermarket replacement front idler for Case compact track loaders listed below. This tension idler fits models from the earliest generation as well as many current models, however, CNH did release a larger diameter idler in 2015 so your existing idler may be two inches larger in diameter than this idler. This is a larger roller at the furthest point forward on the undercarriage. We stock the bottom rollers, sprockets, and the rear idler, but this is the larger front idler roller and it is not interchangeable in the rear position. The idler wheel bolts to the tensioner at the front of the track frame. Replacing a worn-out front tension idler is critical to preventing detracking.
This idler assembly is fully assembled and is designed to reuse your existing factory bolts for easy installation into your yoke. We carry the complete replacement undercarriage for these Case track loaders.
