This part fits a wide range of Bomag single drum rollers — including the BW 142 D-2, BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 177 D-3, BW 177 DH-3, BW 178 D-3, and C 825 C — as well as the MPH 121 recycler/stabilizer. Ordering by part number 05586037 ensures you receive the correct washer for your specific machine without guesswork.
Key Features
- Genuine OEM Spring Tension Integrity — manufactured to Bomag's original load and deflection specifications, ensuring the washer delivers consistent clamping force and spring-back behavior throughout its service life
- Direct-Fit Replacement — matches the original bore, outside diameter, and thickness of the factory-installed washer for a straightforward swap with no rework or shimming
- Broad Single Drum Roller Coverage — confirmed fitment across BW 142 D-2, BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 177 D-3, BW 177 DH-3, BW 178 D-3, BW177D-3, BW177 DH 3, BW145D 3, BW145PDH 3, and C 825 C single drum rollers, plus the MPH 121 recycler/stabilizer
- Fastener Joint Reliability — a properly functioning spring washer maintains bolt preload under vibration and thermal cycling; a worn or flattened washer allows joints to loosen, leading to fretting, misalignment, and accelerated wear on surrounding components
- Verified Part Number Traceability — carrying Bomag part number 05586037, this component is fully traceable through Bomag's OEM supply chain for accurate reordering and service documentation
A spring washer is a hardened, curved or wave-form washer installed beneath a bolt head or nut to maintain clamping load in assemblies subject to vibration and dynamic loading. On heavy compaction equipment like single drum rollers, fasteners are exposed to constant vibration cycles that can gradually back out a standard flat washer arrangement — the spring washer's stored elastic energy counteracts this by continuously pressing against the mating surfaces. When a spring washer loses its temper, flattens, or fractures, bolt preload drops, joints work loose, and components that depend on secure fastening — including drive, frame, and drum assemblies — become prone to wear, noise, and eventual failure.
