The Bomag 05617009 Coupling is a genuine OEM component designed for the BW 120 AD tandem roller. Sourced directly from Bomag, this coupling delivers the exact tolerances and material specifications required for proper drivetrain or hydraulic function on the BW 120 AD. As a genuine OEM part, it matches the original component in every dimension, ensuring a correct installation without guesswork. If you're restoring full performance to your BW 120 AD tandem roller, this is the correct replacement coupling for the job.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional specifications, ensuring the coupling transmits torque or connects fluid lines exactly as the original design intended
- Direct Replacement Fit — engineered to align and seat identically to the original coupling on the BW 120 AD, allowing straightforward installation with standard tooling
- Confirmed BW 120 AD Fitment — verified for BW 120 AD tandem rollers, so you can order with confidence knowing this is the correct part for your machine
- Restored Power Transfer — a worn or damaged coupling can cause slippage, vibration, or loss of drive; replacing it with this genuine component restores smooth, uninterrupted power transmission
- Long-Term Durability — built from OEM-grade materials selected to withstand the operational stresses of continuous compaction work, supporting the service life Bomag designed into the BW 120 AD
A coupling connects two rotating shafts or drivetrain components, transferring torque from one side to the other while accommodating minor misalignment and absorbing shock loads. On a tandem roller like the BW 120 AD, couplings are critical to maintaining consistent drum drive and smooth machine operation across varying compaction surfaces. When a coupling wears, cracks, or fails, the result is vibration, loss of power to the drum, and potential damage to connected components — making timely replacement essential to keeping the machine productive and preventing more costly repairs downstream.
