Cummins Hub Spline Coupling Drive Gear
The BEPCO 200398 Cummins Hub Spline Coupling Drive Gear, sold by Wofford Truck Parts, is an OEM-style spline coupling hub used in Cummins air compressor and accessory drive systems. It transfers engine torque through a precision splined interface, keeping the compressor spinning at the correct speed without slip, vibration, or chatter. Replacing a worn hub helps restore tight spline engagement, reduces drivetrain noise, and protects the compressor input from premature damage. Ideal for heavy-duty fleets, it supports consistent air build and dependable brake performance.

Specifications
The BEPCO 200398 Cummins Hub Spline Coupling Drive Gear is a critical link between Cummins accessory drives and air compressor input assemblies. Over time, heat cycling and torque pulses can wear spline teeth, causing looseness, vibration, or reduced compressor efficiency. Part 200398 replaces the coupling hub to reestablish accurate spline fit and stable torque transfer, helping prevent premature compressor or drive damage. Cummins identifies this hub as a primary fit for M11-family compressor drives, and parts catalogs show its use across multiple Cummins heavy-duty engine platforms. Sold by Wofford Truck Parts, it’s an OEM-pattern service solution for dependable air-system operation.
