Bomag 05740288 Spring Washer

The Bomag 05740288 Spring Washer is a genuine OEM component designed for Bomag BW-series tandem rollers and the BMP 8500 trench compactor. Sourced directly from Bomag, this spring washer delivers an exact match to the original specification, ensuring correct installation without guesswork. Compatible models include the BW 80 AD-2, BW 80 ADS, BW 90 AD-2, BW 90 AC-2, BW 100 ADM-2, BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW 131 ACW-2, BW 131 AD-2, BW 131 ACW-3, BW 131 AD-3, BW 170 AP AM, BW 174 AP, BW 174 ACP, BW 174 ACP-AM, BW 174 AP-AM, BW 174 AP-4 AM, BW 174 AP-4, and the BMP 8500. Choosing a genuine OEM part means this spring washer meets the same dimensional and material standards as the component it replaces, keeping fastened assemblies secure under operational load and vibration.

Key Features

• Genuine OEM Tension Retention — manufactured to Bomag's original material and dimensional standards, maintaining consistent clamping force under the continuous vibration loads typical of tandem roller and trench compactor operation
• Direct Drop-In Replacement — matches the original part number 05740288 exactly, fitting the same fastener positions without any modification to surrounding hardware
• Broad BW-Series and BMP Coverage — confirmed fitment across BW 80, BW 90, BW 100, BW 120, BW 125, BW 131, and BW 174 tandem rollers, as well as the BMP 8500 trench compactor
• Vibration-Resistant Clamping — a correctly functioning spring washer prevents fastener loosening caused by machine vibration; a worn or missing washer can allow critical bolted joints to back off during operation
• Fastener System Integrity — using the correct OEM spring washer maintains proper preload across bolted assemblies, helping to protect surrounding components from the wear and movement that loose fasteners cause

A spring washer is a hardened, slightly conical or wave-formed ring placed beneath a nut or bolt head to apply continuous tension against the fastened joint. Its purpose is to resist the loosening effect of vibration — a significant concern on compaction equipment where the entire machine is subject to sustained dynamic loads. When a spring washer wears flat, fractures, or is omitted, the fastener it secures can gradually back off, leading to joint movement, component wear, and potential hardware loss. Replacing a fatigued spring washer with a correct OEM part restores the clamping integrity of the assembly and protects the components it holds in place.
