The Bomag 31780207 V-Belt is a genuine OEM replacement designed for Bomag BW-series tandem rollers and single drum rollers, including the BW 184 AD, BW 184 AD-2 AM, BW 180 AD, BW 213 D-3, BW 213 PDH-3, BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 178 D-3, and C 850 C single drum rollers. Sourced directly from Bomag, this V-Belt meets the same dimensional and material standards as the belt installed at the factory. Confirmed fitment across multiple BW-series variants and the C 850 C makes part number 31780207 a dependable choice when your roller is due for a drive belt service.
Key Features
- Genuine OEM Belt Construction — manufactured to Bomag's exact cross-section profile and tensile cord specification, so power transfer to the drum or auxiliary drive is consistent throughout the belt's service life
- Drop-In Replacement — matches the original routing and pulley engagement on all listed models, allowing straightforward installation without improvising fit
- Broad BW-Series and C 850 C Coverage — confirmed for BW 184 AD and BW 184 AD-2 AM tandem rollers, BW 180 AD tandem rollers, and BW 213 D-3, BW 213 PDH-3, BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 178 D-3, and C 850 C single drum rollers
- Sustained Drive Efficiency — a properly tensioned, correctly sized V-Belt maintains full drive output to the compaction system; a worn or stretched belt causes slippage, heat buildup, and loss of drum speed
- Verified Part Number Integrity — ordering by Bomag part number 31780207 eliminates the guesswork of cross-referencing aftermarket belt codes that may not match your machine's pulley geometry
A V-Belt transmits rotational power from the engine's drive pulley to one or more driven components — on compaction rollers this typically includes the vibratory system, hydraulic pump, or auxiliary drive. The belt must maintain the correct tension and profile contact to transfer torque without slipping. When a V-Belt stretches, cracks, or frays, the machine loses drive efficiency, components run erratically, and in some cases the vibratory drum stops performing altogether. Replacing the belt at the first sign of wear keeps the drivetrain operating as intended and protects the pulleys and bearings from the additional stress that a slipping belt creates.
