Bomag 08642170 Spring Washer

The Bomag 08642170 Spring Washer is a genuine OEM component designed for a broad range of Bomag single drum rollers, tandem rollers, pneumatic tyred rollers, walk-behind rollers, refuse and landfill compactors, recyclers/stabilizers, and pavers. As a direct OEM replacement sourced through Bomag's authorized parts network, this spring washer carries the same specifications as the original hardware installed at the factory. Confirmed fitment spans dozens of Bomag models, including BW 213 D-4, BW 216 DH-4, BW 226 DH-4, BC 772 RB, BC 972 RB, BF 691 C, MPH 122, and many more — making part number 08642170 one of the most widely applicable fastener components in the Bomag lineup.

Key Features

• OEM Spring Tension Integrity — Manufactured to the original Bomag specification, this spring washer delivers the correct clamp load and deflection characteristics needed to keep fastened assemblies secure under vibration and dynamic loading.
• Drop-In Hardware Replacement — Dimensionally identical to the original, this washer seats and torques to spec without rework, fitting standard fastener assemblies across the supported machine families.
• Exceptionally Wide Model Coverage — A single part number 08642170 serves single drum rollers including BW 213 D-4 and BW 226 DH-4, tandem rollers including BW 202 AD-4 and BW 164 AD, pneumatic tyred rollers, walk-behind rollers, BC-series refuse and landfill compactors, MPH-series recyclers/stabilizers, and the BF 691 C paver.
• Vibration-Resistant Locking Action — The spring washer's controlled flex prevents fastener loosening caused by continuous machine vibration — a critical function on compaction equipment and heavy rollers operating in demanding conditions.
• Genuine Bomag OEM Quality — Supplied as an authentic Bomag part, this component meets the same material hardness and surface treatment standards as the hardware originally assembled into each supported machine.

A spring washer is a split or wave-form hardened washer placed beneath a nut or bolt head to resist loosening caused by vibration, thermal cycling, and dynamic loads. As the fastener is tightened, the washer flexes and stores tension, continuously pressing against both the fastener and the mating surface to maintain clamp force. On heavy compaction equipment like rollers and landfill compactors — machines that generate and absorb continuous vibration — spring washers play an essential role in keeping structural and mechanical assemblies from working loose over time. A missing, flattened, or fatigued spring washer can allow fasteners to back out, leading to loosened covers, brackets, or rotating components and creating the potential for accelerated wear or unexpected failures in the surrounding assembly.
