This is the aftermarket replacement tension idler for the following Volvo mini excavators:
- Volvo EC 55
- Volvo MX 55
- Volvo MX55A
This is the larger idler wheel on the opposite end of the undercarriage from the sprocket. This is the part that pushes out as you grease up the tensioner to expand and tension the rubber track.
Always maintain your rubber track to the proper tension and evaluate your idler wear to prevent de-tracking. Use the blue arrow in the image to reference the installation location.
