The Bomag 31781829 Cylinder Head Gasket is a genuine OEM component designed for BC 771 RB and BC 771 RS refuse and landfill compactors. As a direct Bomag OEM part, this cylinder head gasket is manufactured to the same specifications as the original, ensuring a proper seal between the engine block and cylinder head. This gasket is the correct fitment for BC 771 RB and BC 771 RS machines, giving operators confidence they are installing the right part the first time.
Key Features
- OEM-Grade Sealing Materials — Manufactured by Bomag to original material and compression specifications, delivering the multi-layer sealing integrity required for a heavy-duty compactor engine.
- Direct Replacement Fit — Engineered to match the original cylinder head gasket geometry, seating correctly on installation without rework or adaptation.
- Confirmed Compactor Fitment — Verified for BC 771 RB and BC 771 RS refuse and landfill compactors under part number 31781829.
- Engine Combustion Integrity — A sound cylinder head gasket maintains proper compression and keeps coolant and oil passages separated, allowing the engine to deliver full power under the demanding loads of landfill compaction work.
- Fuel and Coolant Leak Prevention — A failed or worn head gasket allows combustion gases, coolant, and oil to mix or escape — replacing it promptly with a genuine OEM part prevents engine damage and costly repairs.
The cylinder head gasket sits between the engine block and the cylinder head, forming a critical seal that contains combustion pressure while keeping engine oil and coolant in their separate passages. On heavy refuse and landfill compactors like the BC 771 RB and BC 771 RS, the engine operates under sustained high load, placing significant stress on this gasket over time. A worn or blown cylinder head gasket typically causes loss of compression, overheating, white exhaust smoke, or coolant contamination of the engine oil — any of which will take a machine out of service if not addressed.
