PIN IDLER (Bobcat BC7100963)

A worn idler pin can cause uneven track tension and accelerated undercarriage wear. This aftermarket replacement part references Bobcat as the OE maker and cross-references part number BC7100963. The pin serves as a pivot point for the idler wheel, allowing it to rotate freely as the track moves. When the pin surface becomes scored or corroded, the idler may bind, leading to track misalignment or premature bushing failure. In heavy dozing or grading work, a seized idler pin forces the track to drag rather than roll smoothly. Verify the serial number or application, then call (562) 693-7748. The part is listed as a hardware pin in the catalog.
