The list above is for reference. It is crucial to verify the OEM part number or idler dimensions.
Working on track undercarriages is extremely dangerous. Use extreme caution when releasing and tensioning tracks. Track tension (grease) must be released before service. The machine must be securely supported on certified stands. Never rely solely on the machine's own hydraulics.
The idler wheel is a fundamental undercarriage component. It has two roles: guiding the track chain onto the frame, and working with the spring and tensioner cylinder to maintain correct track tension. A failed idler will lead to de-tracking and accelerated wear of the entire undercarriage.

The idler wheel (this part, JRA0214) is smooth and sits at the front of the undercarriage, used to guide and tension the track. The sprocket (drive wheel) has teeth, sits at the rear, and is connected to the final drive (travel motor) to propel the track.
2. What does "short guides" mean?This refers to the height/length of the center flanges that guide the track chain. Depending on the track frame and chain type used, some machines require short guides and others require long guides. This model is the short guide version.
3. Does this idler come with the yoke/tensioner assembly?No. This product is the idler wheel itself, which is a maintenance-free, sealed unit with internal bearings. It is designed to be mounted onto your machine's existing tensioner yoke.
