A genuine idler wheel (tensioner), a key component of the tracked undercarriage. Its function is to work with the tensioner cylinder to maintain correct track tension and to guide the track along the undercarriage frame. Made from high-quality cast steel, it provides maximum resistance to abrasion and mechanical damage, ensuring long and trouble-free operation.

The list above is for reference. We recommend verifying the part number on your machine before purchasing.
An idler wheel failure is an ideal time to inspect the entire undercarriage. Check the condition of the track rollers, sprockets, and the track itself. Remember to regularly clean the undercarriage of mud and rocks and to maintain correct track tension, which significantly extends the life of all components.
The idler wheel is one of the most important elements of the undercarriage. Its failure leads to a loss of correct track tension, which can result in the track coming off, accelerated wear, and in extreme cases, immobilization of the machine and damage to the undercarriage frame.
Replace the idler wheel if you notice:

If the idler wheel has no play and turns smoothly, the problem is most likely with the tensioner cylinder (grease ram) or its valve (grease nipple). There may be an internal grease leak, preventing the cylinder from holding pressure.
2. What is the main cause of tracks breaking or wearing out quickly?Besides operating on rocky ground, one of the most common causes is a worn idler wheel. Its worn or "sharp" running surface acts like a knife, cutting and destroying the track's internal steel cords, leading to its premature failure.
3. Can I replace just the bearings in the old wheel?This is not recommended. Idler wheels are supplied as a complete, sealed unit. Additionally, it's not just the bearing that wears, but also the running surface of the wheel. Replacing it with a new, complete unit is the most reliable solution.
4. What causes the most damage to idler wheels?The most common causes of premature wear are: operating with an overly tight track, high-speed travel over long distances (especially in reverse), and working in very abrasive terrain (sand, rocks).
