The Bomag 05540987 Adapter is a genuine OEM component designed for Bomag BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 120 AD 4, and BW 125 AD-4 tandem rollers. Sourced directly from Bomag, this adapter carries the same specifications as the part that left the factory floor, so you can be confident it connects and seats exactly as intended. If you're servicing or rebuilding a BW 100- or BW 120-series tandem roller, verifying part number 05540987 against your machine's parts manual is the surest way to confirm you have the right component before wrenching.
Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Bomag's exact interface tolerances, ensuring the adapter mates flush with mating components without shimming or rework
- Direct Drop-In Replacement — matches the original mounting pattern and thread specification of the outgoing adapter, so installation follows the standard service procedure
- Broad BW-Series Tandem Roller Coverage — fits the BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 120 AD 4, and BW 125 AD-4 tandem rollers, covering multiple drive and drum configurations within the family
- Maintains Drivetrain or System Integrity — a correctly fitted adapter preserves proper alignment and load transfer between connected assemblies, protecting downstream components from premature wear
- Traceable Part Number — order and store this component by part number 05540987 to simplify inventory management and future reorders
An adapter serves as the mechanical interface between two assemblies or components that must be joined, aligned, or converted to a compatible connection point. On tandem rollers like the BW 100 and BW 120 series, adapters are used throughout the drivetrain, hydraulic circuit, and drum assembly to ensure that forces, fluid, or motion are transferred cleanly from one component to the next. When an adapter becomes worn, cracked, or stripped, it can introduce misalignment, fluid leakage, or load imbalance that accelerates wear on surrounding parts — making timely replacement essential to keeping the roller performing at spec.
