Common Maintenance Parts for JCB & CAT 5-Ton Class

To keep your swing system operating smoothly, maintain these related items:

Q&A Section

Q1: Is this motor a direct fit for the CAT 305C and 305D models?

A: The PCR-5B-30A is widely used across the CAT 305 platform. However, always verify the specific "FGP" code and shaft spline count, as variations exist between different sub-series (C, D, E, etc.).

Q2: What is the most common sign that this motor needs replacement?

A: "Swing drift"—where the cabin continues to move after the operator centers the joystick—is the most common sign. This usually indicates worn internal brake discs or leaking relief valves.

Q3: Does the motor come with the reduction gearbox (swing drive)?

A: Typically, part number PCR-5B-30A-FGP-9537A refers to the hydraulic motor section. Some suppliers offer it as a complete assembly with the gearbox, so it is important to confirm before purchase.
