105-8739 1058739 Plastic Bushing

Seat: Designed to work with Caterpillar's proprietary Sealed and Lubricated Track system. This system forces grease between the pin and bushing, reducing internal wear and "pin bushing rotation."

Wear Limit: A critical parameter is the allowable wear before the entire track chain must be rebuilt or replaced. As the bushing wears, its ID increases. Caterpillar provides a specific "wear gauge" measurement. When the bushing ID has worn by a certain amount (e.g., several millimeters), it is considered at its end-of-life to prevent catastrophic failure of the track chain.

This 105-8739 bushing is used for cat machine.
