The Bomag 05723388 Piston Ring Set is a genuine OEM component designed for BW 65 HS and BW 65 S walk-behind light rollers, BW 75 E walk-behind light rollers, and BW 35 and BW 35 W trench compactors. Sourced directly from Bomag, this piston ring set delivers an exact match to the original engine specification, ensuring a correct seal between the piston and cylinder bore. Confirm part number 05723388 against your machine's serial plate before ordering to ensure full compatibility.
Key Features
- OEM Sealing Precision — Each ring in this set is manufactured to Bomag's original compression and oil-control tolerances, maintaining proper cylinder pressure and minimizing oil consumption throughout the engine's service life.
- Direct Engine Replacement — This piston ring set installs into the existing cylinder bore without machining or modification, matching the original ring groove dimensions and end-gap specifications of the host engine.
- Broad Model Coverage — Fits BW 65 HS, BW 65 S, and BW 75 E walk-behind light rollers, as well as BW 35 and BW 35 W trench compactors, making it a versatile service part across multiple Bomag machine families.
- Restored Compression Performance — Worn or broken rings cause loss of cylinder compression, increased oil burn, and hard starting; replacing them with this OEM set restores the engine's power output and throttle response.
- Genuine Bomag Quality — As a genuine OEM part, the part meets the same material and heat-treatment standards as the rings originally installed at the factory, supporting a durable and consistent rebuild.
Piston rings form the dynamic seal between the piston and the cylinder wall inside the engine, controlling compression pressure and regulating how much oil reaches the combustion chamber. A healthy set of rings allows the engine to build full compression on every stroke, delivering the power needed to drive the compaction drum or vibratory mechanism effectively. When rings wear, crack, or lose tension, compression drops, oil consumption rises, and the engine may smoke, lose power, or become difficult to start — all signs that a ring set replacement is overdue.
