Sourced directly from Bomag, this valve seat ring meets the original design and material specifications for your machine's engine. This part is the correct, catalog-verified replacement identified by part number 05729193, giving you confidence that you are ordering exactly what your roller requires. Compatible across both single drum and tandem roller configurations in the BW lineup, it covers an extensive range of generation-4 and generation-5 variants.
Key Features
- Genuine OEM Material Grade — manufactured to Bomag's original hardness and thermal-resistance specifications for valve seat rings, ensuring proper sealing under sustained engine operating temperatures
- Direct Engine Replacement — machined to the exact bore and seat geometry of the original, allowing installation into the cylinder head without rework or resizing
- Broad BW-Series Coverage — fits an extensive range of Bomag single drum rollers and tandem rollers including the BW 124 DH-4, BW 145 D-5, BW 177 DH-4, BW 179 PDH-4, BW 161 AD-4, BW 154 AD-4 AM, BW 151 AC-4, BW 141 AD-4, and additional variants across the BW 124, BW 145, BW 177, and BW 179 families
- Consistent Compression Sealing — a correctly seated valve seat ring maintains the combustion seal between the valve face and cylinder head, preserving compression ratio and engine output; a worn or cracked seat causes compression loss, rough running, and accelerated valve wear
- Catalog-Verified Part Number — part number 05729193 is cross-referenced directly against Bomag's OEM parts catalog, so fitment to your specific machine variant is confirmed before the part ships
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 is engineered from heat-resistant alloy to withstand the repeated mechanical impact and thermal cycling of normal engine operation. When a valve seat ring wears, cracks, or recedes, the valve can no longer form a gas-tight seal, leading to loss of compression, increased fuel consumption, overheating, and eventual engine damage — making timely replacement critical to keeping your roller productive on the job.
