The Bomag 05715791 Valve Seat is a genuine OEM component designed for Bomag BW 75 ADL and BW 75 AD walk-behind rollers and 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 delivers the exact dimensional tolerances and material grade your engine demands. Whether you are rebuilding a cylinder head or replacing a worn seat, this OEM part ensures a proper seal and restores correct valve operation across all covered machine models.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact hardness and surface-finish specifications, ensuring consistent valve-to-seat contact and gas-tight combustion chamber sealing
- Direct Drop-In Replacement — matches the original press-fit dimensions so this valve seat installs into the cylinder head without rework or machining adjustments
- Broad Bomag Coverage — fits BW 75 AD and BW 75 ADL walk-behind rollers as well as BW 650 T, BW 850 T, BW 850 TR, BW 1050 T, and BW 85 T trench compactors, making it a versatile stock item for mixed fleets
- Sustained Engine Compression — a correctly seated valve maintains proper compression and combustion efficiency; a worn or damaged seat leads to compression loss, hard starting, and reduced machine output
- Verified Part Number Fitment — ordering by Bomag part number 05715791 eliminates guesswork and confirms you receive the correct seat geometry for your specific engine application
A valve seat is the precision-machined ring pressed into the cylinder head against which the intake or exhaust valve closes to form a gas-tight seal. It controls how well combustion gases are contained in the cylinder and plays a direct role in engine compression, power output, and fuel efficiency. When a valve seat wears, erodes, or becomes pitted, the valve can no longer seal completely — allowing combustion gases to escape, which causes a loss of compression, rough running, increased fuel consumption, and ultimately engine damage if left unaddressed. Replacing this seat with a correctly dimensioned OEM part restores the sealing surface and brings the engine back to proper operating condition.
