This part is compatible across a wide range of Bomag tandem roller models, including the BW 80 AD-2, BW 90 AD-2, BW 100 AD-4, BW 120 AD-5, BW 131 AD-5, BW 138 AD-5, and many more, as well as the BMP 8500 and BMP 8500 Kubota trench compactors. When it comes time to service your machine, using part number 05740079 ensures the correct fit and consistent performance every time.
Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to Bomag's original load and deflection specifications, so this spring washer delivers the correct clamping force and elastic recovery that the fastener joint demands.
- Drop-In Replacement — Matches the original profile, inner diameter, and thickness exactly, seating correctly without modification on BW-series tandem rollers and BMP 8500 trench compactors.
- Broad Tandem Roller Coverage — Fits an extensive range of Bomag tandem rollers, including the BW 80 AD-2, BW 90 AD-5, BW 100 AC-5, BW 115 AD-3, BW 120 AC-4, BW 125 AD-4, BW 131 AD-3, BW 135 AD-5, BW 138 AC-5, BW 100 SCC-5, and additional models across the BW series, plus the BMP 8500 and BMP 8500 Kubota.
- Fastener Joint Protection — A properly functioning spring washer absorbs vibration and maintains bolt preload under the high-frequency operating conditions typical of compaction equipment, preventing fastener loosening over time.
A spring washer is a small but critical hardware component used throughout compaction equipment to maintain consistent clamping force in bolted connections. In high-vibration environments like tandem rollers and trench compactors, standard flat washers can allow fasteners to gradually back out, leading to loose assemblies, accelerated wear, and potential mechanical failure. The spring washer's dished or wave profile compresses under load and continuously pushes back against the fastener, keeping the joint tight even as the machine vibrates during operation. Replacing a worn or damaged spring washer with a genuine OEM part like the part restores the correct preload to the connection and helps protect surrounding components from the consequences of a loose fastener.
