The Bomag 05012684 Coupling Hub is a genuine OEM replacement designed for BW 124 and BW 145 series single drum rollers, including the C815D. Sourced directly from Bomag, this coupling hub matches the original component specification, ensuring a direct, drop-in installation with no guesswork. This part covers a broad range of BW 124 and BW 145 variants — including DH, PDH, and D configurations across multiple generation suffixes — making it a dependable choice when servicing these machines in the field.
Key Features
- Genuine OEM Torque Transfer Integrity — manufactured to Bomag's original coupling geometry and material spec, maintaining the precise torque transmission characteristics this drivetrain connection demands
- Direct-Fit Replacement — engineered to match the original mounting interface on BW 124 and BW 145 series single drum rollers, including DH, PDH, and D drive variants, as well as the C815D
- Broad Series Coverage — fits BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 145 DH 40, BW 145 PDH 40, and the C815D single drum roller
- Protects Drivetrain Components — a correctly seated coupling hub absorbs and transmits rotational force without slack or misalignment; a worn or failed hub can cause vibration, drive loss, and accelerated wear on connected drivetrain parts
- Verified Part Number Fitment — order with confidence using Bomag part number 05012684, cross-referenced against the fitment list for the models above
The coupling hub is a critical drivetrain component that connects rotating shafts or assemblies, transmitting torque between the power source and the driven system. It acts as the mechanical bridge that keeps rotational force flowing smoothly and consistently through the driveline. When a coupling hub wears, cracks, or becomes loose, the result is often vibration, power loss, or erratic machine behavior — and left unaddressed, a failed hub can cause cascading damage to adjacent drivetrain components. Replacing it promptly with a correctly specified part restores smooth power delivery and protects the surrounding assembly.
