The Bomag 31780015 Tensioning Pulley is a genuine OEM component designed for BC 771 RB and BC 771 RS refuse and landfill compactors. Sourced directly from Bomag, this tensioning pulley is built to the exact specifications required by these heavy-duty machines. It installs directly in place of the original, delivering a correct and consistent fit on both the BC 771 RB and BC 771 RS without guesswork or modification.
Key Features
- Genuine OEM Construction — manufactured to Bomag's own engineering standards, ensuring the correct load rating, rotational geometry, and belt-contact profile for sustained drive system performance on refuse and landfill compactors
- Direct OEM Replacement — engineered to match the original mounting configuration on the BC 771 RB and BC 771 RS, so the pulley seats and aligns correctly upon installation
- Confirmed Fitment — verified for the BC 771 RB and BC 771 RS refuse and landfill compactors; cross-reference part number 31780015 before ordering to confirm compatibility
- Drive Belt Integrity — a properly functioning tensioning pulley maintains consistent belt tension, preventing slippage, uneven wear, and premature belt failure that can interrupt compactor operation
- Long-Term Durability — OEM-grade materials resist the heat, vibration, and load cycles that are characteristic of continuous landfill and refuse compaction work
A tensioning pulley keeps the drive belt under the correct amount of tension throughout the operating cycle. Without adequate tension, belts can slip or jump, causing loss of drive to auxiliary or primary systems and accelerating wear on both the belt and surrounding components. When the tensioning pulley wears or seizes, belt tension becomes erratic, which can result in overheating, component damage, or an unexpected shutdown — keeping this component in serviceable condition is essential to keeping the BC 771 RB and BC 771 RS compactors running productively on the landfill.
