How do I know if my carrier roller is worn out?

Expert_Answer

Common signs of a worn carrier roller are noise, heat, oil leakage, and excessive play. If the roller feels rough when rotated by hand, spins unevenly, or has noticeable side-to-side movement, the internal bearing or bushing may be worn. You may also see a flat spot on the tread, uneven wear on the track chain, or the track sagging more than normal between the idler and sprocket. In severe cases, the roller can seize, which accelerates wear on the track and undercarriage. Inspect the seals for damage and check for oil loss if it is an oil-filled roller. If you are unsure, compare it to a new roller or have the undercarriage measured. VANROCK supplies carrier rollers and other undercarriage parts for 54+ machinery brands.
