The Bomag 05715792 Valve Seat is a genuine OEM component designed for BW 75 ADL and BW 75 AD walk-behind light rollers, as well as BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T trench compactors. Sourced directly from Bomag, this valve seat matches the original part in material, geometry, and sealing performance — ensuring a drop-in fit without rework. If your engine is showing signs of compression loss, rough running, or reduced power, a worn valve seat is often the root cause, and this genuine OEM replacement restores the seal to as-built condition.
Key Features
- Genuine OEM Sealing Integrity — machined to the exact hardness and dimensional tolerances required for consistent valve-to-seat contact and sustained compression in Bomag engines
- Direct Engine Fitment — engineered to seat flush in the cylinder head without additional machining or shimming, preserving correct valve clearance and combustion chamber geometry
- Broad Bomag Coverage — fits BW 75 ADL and BW 75 AD walk-behind light rollers and BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T trench compactors
- Compression Restoration — a correctly seated valve prevents combustion gas blow-by, restoring full cylinder pressure and protecting against accelerated valve, guide, and piston wear
- Fuel System Safety — a properly sealed valve seat is critical to maintaining correct combustion temperatures; a failed seat can lead to valve burning, misfires, and uncontrolled fuel waste
The valve seat is a precision ring pressed into the cylinder head that provides the hardened mating surface against which the engine valve closes on every combustion cycle. It forms a gas-tight seal that holds cylinder pressure during compression and combustion, directly determining how much power the engine can produce. When a valve seat wears, pits, or recedes, the seal deteriorates — resulting in compression loss, hard starting, increased fuel consumption, and eventual valve damage. Replacing a worn seat with a genuine Bomag part returns the engine to proper operating specification and prevents more costly cylinder head repairs down the line.
