The Bomag 05901834 Outer Disc is a genuine OEM component designed for a wide range of Bomag single drum rollers and tandem rollers, including the BW 177, BW 179, BW 145, and BW 174 series. Sourced directly from Bomag, this outer disc matches the original part in every dimension and material specification, ensuring a drop-in replacement with no adaptation needed. Whether you are servicing a BW 177 DH-5, a BW 179 PDH-4, a BW 145 PDH-5, or a BW 154 AD-4 tandem roller, part number 05901834 is the correct OEM choice for restoring full disc function.
Key Features
- Genuine OEM Disc Integrity — manufactured to Bomag's exact material and dimensional tolerances, preserving the friction and wear characteristics the original disc assembly was engineered to deliver
- Direct-Fit Replacement — matches the original mounting profile and thickness so this outer disc seats correctly within the disc pack without shimming or rework
- Broad Bomag Roller Coverage — fits BW 177, BW 179, and BW 145 single drum rollers across multiple generation variants (-3, -4, -5, -40, -50), as well as BW 141, BW 151, BW 154, and BW 174 tandem rollers, including AM and PL configurations
- Disc Pack Performance — a correctly fitted outer disc maintains proper clamping force and heat dissipation across the disc assembly, preventing slippage, premature wear, and drivetrain stress that a worn disc would otherwise cause
- Braking and Drive Safety — the outer disc is a load-bearing element in the wet disc brake or drive coupling system; replacing a worn disc with a genuine OEM part helps ensure the roller responds predictably under load and on grade
The outer disc is a friction and clamping component housed within a multi-disc assembly — typically part of a wet brake or drum drive system on compaction rollers. It works in conjunction with inner discs and pressure plates to transfer torque or apply braking force through controlled surface contact. When an outer disc wears thin, becomes glazed, or warps from heat, the assembly loses clamping efficiency, which can result in slipping, reduced braking response, or uneven torque delivery to the drum. Replacing the disc promptly with a genuine OEM part restores the assembly to its designed operating capacity and protects the surrounding components from accelerated wear.
