The Bomag 65040120 Washer is a genuine OEM washer designed for BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5 tandem rollers. Sourced directly from Bomag, this washer delivers the exact dimensions and material grade specified for these machines, ensuring a correct, secure fit without rework or modification. Confirmed compatible with the BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5 tandem rollers, this component is the straight OEM swap for worn or damaged hardware in the assembly it serves.
Key Features
- OEM-Spec Material and Dimensions — Manufactured to Bomag's exact thickness, bore, and hardness specifications, so the washer seats and distributes load the way the original design requires.
- Direct Hardware Replacement — Matches the original fastener assembly hole pattern and seating surface, dropping in without adjustment or shimming.
- Confirmed Tandem Roller Fitment — Verified for the BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5 tandem rollers, covering the key models in this compaction lineup.
- Proper Load Distribution — A correctly sized washer prevents fastener pull-through and surface damage; an undersized or worn washer can allow joint movement that leads to loosening and accelerated wear on surrounding components.
- Genuine Bomag Part — Supplied as an authentic OEM component, backed by Bomag's part number 65040120 for straightforward ordering and inventory management.
A washer functions as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. By spreading clamping force over a wider area, it protects the mating surface from indentation, prevents fastener loosening under vibration, and maintains joint integrity over time. On tandem rollers like the BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5, which generate continuous vibration during operation, using a washer that matches the original specification is essential; an incorrect or worn washer can allow fasteners to work loose, compromising the stability of the assembly and leading to more extensive repairs.
