The Bomag 31781559 V-Belt is a genuine OEM component designed for BC 771 RB and BC 771 RS refuse and landfill compactors. Sourced directly from Bomag, this V-Belt meets the original equipment specification for a drop-in replacement with no guesswork on sizing or compatibility. It is the correct belt for both the BC 771 RB and BC 771 RS, ensuring proper power transmission across the drivetrain or auxiliary systems on these machines. When you need to restore full operating capacity on your compactor, this is the part to reach for.
Key Features
- OEM-Spec Belt Construction — manufactured to Bomag's original cross-section, length, and tension profile, so the belt seats correctly in its pulleys and delivers the same load capacity as the belt that left the factory
- Direct Replacement for BC 771 RB and BC 771 RS — matched to part number 31781559 and validated against both BC 771 RB and BC 771 RS refuse and landfill compactors for a straight swap
- Verified Fitment on BC 771-Series Refuse Compactors — covers the BC 771 RB and BC 771 RS, giving operators of either machine a single confirmed OEM solution
- Sustained Power Transfer — a correctly tensioned V-Belt keeps driven components running at the right speed and torque; a worn or cracked belt slips under load, reduces output, and can cause sudden component failure on the job
- Genuine Bomag Part — supplied as genuine OEM, backed by Bomag's parts program and traceable to part number 31781559 for accurate ordering and service records
A V-Belt transmits rotational power from the engine or a drive pulley to one or more driven components — such as a hydraulic pump, alternator, or cooling fan — by gripping the angled sides of mating sheaves. On heavy refuse and landfill compactors like the BC 771 RB and BC 771 RS, these belts operate under sustained load and heat cycles, causing gradual stretching, glazing, or cracking over time. A belt that has lost its profile or elasticity will slip under peak demand, starving driven systems of power and accelerating wear on both the belt and its pulleys. Replacing it on schedule with an OEM-spec belt restores correct tension, maintains full system output, and protects the components that depend on it.
