This cylindrical heavy-duty machinery component operates in areas subjected to high pressure and frictional forces within track systems.
Bearing the part number 21M-27-11240, this track final drive pin is compatible with the PC400-7, PC450-8, PC450-7, PC400-8, PC600-6, and PC650-6 excavator series. During maintenance and replacement operations, inspecting worn pin housings while disassembling the final drive group and renewing them along with bushings when necessary directly increases the service life of the newly installed component.
Have you checked the excavator's serial number and final drive reduction configuration while using the component coded 21M2711240 on your compatible machine series?
