136-2393 Carrier Roller — Cat Excavator 307B

This carrier roller supports the upper portion of the track chain, reducing friction and wear as the track moves. Manufactured to meet stringent OEM standards, it provides smooth rotation and consistent support, unlike a worn roller with a damaged bearing or flat spot. Operators may experience increased vibration, unusual noises from the undercarriage, or accelerated track wear when this roller fails.

Failure Symptoms

The first indication of a failing carrier roller is often an audible noise, such as grinding or rumbling, coming from the undercarriage. If left unaddressed, the damaged bearing can seize or the roller may develop a flat spot, causing increased vibration and accelerated wear on the track chain. Continued operation risks damage to the track links and other undercarriage components.

Installation Tip

Clean the mounting surface and hardware thoroughly before installing the new roller to ensure a secure fit. Avoid overtightening the mounting bolts, which can strip threads or damage the roller housing.

Service Note

Inspect track chains, idlers, and final drives for wear when replacing carrier rollers.
