The Bomag 05728027 Cylinder and Piston is a genuine OEM assembly designed for BP and BPR series vibratory plates and the BW 71 E-2 walk-behind roller. Sourced directly from Bomag, this component delivers an exact match to the original specification — no guesswork on dimensions or tolerancing. Confirmed fitment covers the BP 18/45 D-2 and BP 25/48 D vibratory plates, the BPR30/38 and BPR 25/45 D-3 reversible vibratory plates, and the BW 71 E-2 walk-behind roller. Ordering by part number 05728027 ensures you receive the correct assembly for your machine.
Key Features
- OEM-Matched Bore and Stroke Dimensions — manufactured to the exact cylinder bore and piston clearance of the original, ensuring proper compression and engine output on every compaction cycle
- Direct-Fit Assembly — this cylinder and piston unit installs into the original engine block without machining or adaptation, retaining all factory mounting points and porting alignment
- Broad Vibratory Plate and Roller Coverage — fits the BP 18/45 D-2, BP 25/48 D, BPR30/38, BPR 25/45 D-3, and BW 71 E-2, covering both forward and reversible plate families as well as a walk-behind roller
- Restored Compression and Power Delivery — a worn cylinder or piston causes loss of compression, hard starting, and reduced centrifugal force output; replacing this assembly brings engine performance back to operating spec
- Genuine Bomag OEM Part — supplied as an authentic Bomag replacement, backed by verified part number 05728027 for full catalog traceability
The cylinder and piston form the core of the engine's power stroke — the piston compresses the air-fuel mixture inside the cylinder, and the resulting combustion drives the crankshaft that powers the machine's vibration mechanism. When the cylinder bore wears or the piston rings lose their seal, compression drops, leading to difficult starting, poor throttle response, and reduced compaction force. Replacing this assembly with a correctly sized OEM unit restores the engine's ability to generate consistent power and keeps the compactor operating at its rated output.
