Bomag 32010043 Spring Washer

The Bomag 32010043 Spring Washer is a genuine OEM component designed for Bomag single drum rollers across the BW 145, BW 177, BW 179, BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, BW 220, BW 226 series, and select C-series single drum rollers including the C 825 C and C 850 C. As a direct OEM replacement sourced from Bomag, this spring washer matches the original specification exactly — no guesswork on fit or function. Verified compatibility spans -3, -4, -5, and -40 generation variants, covering a broad range of machines in active fleet use across North America and beyond.

Key Features

• Genuine OEM Construction — manufactured to Bomag's original material hardness and spring-rate specification, ensuring consistent clamping force and resistance to fatigue that a worn or incorrect washer cannot deliver
• Direct-Fit Replacement — part number 32010043 matches the original dimensional profile, seating flush in the same fastener stack without shimming or modification
• Broad Single Drum Roller Coverage — fits Bomag BW 145, BW 177, BW 179, BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, BW 220, BW 226, C 825 C, and C 850 C single drum rollers across multiple generation variants
• Fastener Integrity Under Vibration — a correctly functioning spring washer maintains bolt preload through the high-vibration operating cycles that define single drum roller work; a failed or flattened washer allows fasteners to loosen, leading to accelerated wear and potential structural damage
• Multi-Generation Fleet Compatibility — covers -3, -4, -4i, -5, and -40 generation machines, making this a single part number that services a wide cross-section of an aging or mixed BW-series fleet

A spring washer is a deceptively simple but load-critical fastener component. It sits beneath a bolt or nut head and uses its slightly dished or helical profile to apply continuous tension against the fastener, counteracting the loosening effect of vibration and thermal cycling. On single drum soil compactors like the Bomag BW series, where the entire machine is engineered to generate and transmit high compaction forces, every fastened joint is exposed to relentless vibratory stress. When a spring washer flattens, cracks, or corrodes beyond its elastic range, it loses the ability to maintain clamp load — bolts work loose, mating surfaces shift, and what begins as a minor hardware issue can escalate into damaged housings, misaligned assemblies, or unsafe operation. Replacing a fatigued spring washer with the correct OEM part, such as the Bomag 32010043, restores the fastener joint to its designed preload and keeps critical assemblies secure through demanding compaction work.
