The swing machinery pinion gear shaft with part number 208-26-52242 (or 2082652242) is compatible with PC400-6, PC400-7, PC400-8, PC450-6, PC450-7, PC450-8, and PC550-8 heavy equipment models.
As an essential component of the swing system, this pinion gear and shaft assembly ensures high torque transmission and mechanical synchronization within the machinery structure. Proper engagement of gear profiles is critical for excavator swing reduction groups operating in harsh field conditions.
During part replacement, tolerances of the swing gear assembly and bearing housings on the existing chassis should be checked prior to installation. It is recommended to verify your machine serial number and the 208-26-52242 reference code on your swing machinery housing before placing an order.
