The Bomag 05717933 Valve Seat Ring is a genuine OEM component designed for a wide range of Bomag pavers, single drum rollers, tandem rollers, pneumatic tyred rollers, and cold milling machines. Sourced directly from Bomag, this valve seat ring matches the original specification for a drop-in installation with no guesswork on fit or compatibility. Confirmed fitment spans models including the BF 691 C, BF 800 C S500, BF 800 P S500, BW 226 DH-4, BW 219 D-5, BW 219 DH-5, BW 226 PDH-5, BW 202 AD-4, BW 203 AD-4, BW 190 AD-4, BW 27 RH, BW 28 RH, BM 500/15, and BM 600/15, among others. When a valve seat ring wears or fails, engine compression suffers immediately — replacing it with an authentic Bomag part restores proper sealing and keeps your equipment running at full capacity.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact hardness and dimensional tolerances for consistent valve-to-seat contact and full compression retention
- Direct Engine Installation — matches the original press-fit diameter and seat geometry for straightforward installation into the cylinder head without additional machining
- Broad Equipment Coverage — fits Bomag pavers including the BF 691 C and BF 800 C S600, single drum rollers including the BW 226 PDH-5 and BW 219 D-4, tandem rollers including the BW 203 AD-4 and BW 205 AD 4, pneumatic tyred rollers including the BW 27 RH and BW 28 RH, and cold milling machines including the BM 500/15 and BM 600/15
- Compression and Combustion Performance — a worn valve seat ring causes loss of combustion seal, resulting in misfires, power loss, and excessive fuel consumption; this part restores the tight seal the engine depends on
- Authentic Bomag Part — carries genuine OEM verification under part number 05717933, eliminating fitment uncertainty and ensuring this part meets the same standards as what left the factory
The valve seat ring is a hardened insert pressed into the cylinder head that provides the precision sealing surface against which the engine's intake or exhaust valve closes on every combustion cycle. It withstands extreme heat and repeated mechanical impact to maintain an airtight seal that is essential for correct compression and efficient combustion. When a valve seat ring becomes worn, pitted, or damaged, the valve can no longer seal completely, leading to compression loss, rough running, increased exhaust emissions, and — if left unaddressed — accelerated valve and cylinder head damage.
