The Bomag 80040116 Oscillating Articulating Joint Assembly is a genuine OEM component designed for BW 80 AD-2, BW 80 ADS, BW 90 AC-2, and BW 90 AD-2 tandem rollers. Sourced directly from Bomag, this assembly delivers the exact fit and dimensional accuracy required to maintain the steering and oscillation function of your machine. If you are sourcing by part number 80040116, this is the correct OEM-verified replacement for your Bomag tandem roller.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original engineering tolerances, ensuring the joint pivots and articulates with the same load capacity and range of motion as the original assembly
- Direct Replacement Fit — engineered to install into the articulation point of the frame without modification, restoring the mechanical connection between front and rear drum sections
- Confirmed Tandem Roller Fitment — compatible with BW 80 AD-2, BW 80 ADS, BW 90 AC-2, and BW 90 AD-2 tandem rollers, covering multiple variants across the BW 80 and BW 90 series
- Steering Integrity Restored — a worn or damaged articulating joint causes imprecise steering response and uneven drum tracking; replacing it with part number 80040116 brings steering feel and compaction accuracy back to spec
- Oscillation Function Preserved — the oscillating design allows each drum to follow uneven ground independently, and this assembly maintains that capability to protect asphalt surface quality during compaction passes
The oscillating articulating joint assembly connects the front and rear frames of a tandem roller, serving two critical functions: it allows the machine to steer by pivoting at the articulation point, and it permits each drum to oscillate independently so both drums maintain consistent ground contact on uneven or crowned surfaces. When this joint wears, becomes loose, or fails, operators will notice sloppy steering, vibration through the frame, and inconsistent drum pressure — all of which compromise compaction quality and can accelerate wear on surrounding components. Replacing a failed assembly promptly keeps the machine operating with the control and surface-finish performance that tandem roller work demands.
