The Bomag 05728143 Cylinder and Piston is a genuine OEM component designed for Bomag vibratory plates, including BPR 25/40 D reversible vibratory plates, BP 15/45 D-2, BP 15/45, and BP 18/45 D-2 vibratory plates, as well as BPR30 /38, BPR 30/38 D-2, and BPR 30/38 D-3 reversible vibratory plates. Sourced directly from Bomag, this assembly carries the exact OEM specifications your machine was built around, ensuring a seamless drop-in installation with no guesswork on fit or clearances. If your compaction output has dropped, the machine is losing power, or there is visible wear or scoring in the cylinder bore, replacing this assembly restores full compression and gets your plate back to peak performance on the jobsite.
Key Features
- Genuine OEM Compression Integrity — machined to Bomag's exact bore diameter and piston ring tolerances, maintaining the compression ratios the engine was designed to deliver
- Direct-Fit Assembly — supplied as a matched cylinder and piston unit with OEM mounting dimensions, fitting the engine bay of supported Bomag vibratory plates without modification to mounts, ports, or fastener patterns
- Broad Vibratory Plate Coverage — fits the BPR 25/40 D, BPR30 /38, BPR 30/38 D-2, and BPR 30/38 D-3 reversible vibratory plates, as well as the BP 15/45 D-2, BP 15/45, and BP 18/45 D-2 forward vibratory plates
- Restored Engine Power Output — a worn cylinder or piston causes lost compression, hard starting, excessive fuel consumption, and reduced centrifugal force; this assembly corrects all of these by returning the engine to its rated compression
- Matched Piston-to-Bore Clearance — supplied as an OEM-matched pair, eliminating the risk of clearance mismatches that lead to blow-by, oil consumption, or premature wear that can occur when components are sourced separately
The cylinder and piston form the core of the engine's combustion chamber. The piston travels up and down inside the cylinder bore, compressing the air-fuel mixture so combustion can generate the power that drives the vibratory mechanism of the plate. When the cylinder bore becomes scored or the piston rings lose their seal, compression drops sharply — the engine struggles to start, runs rough, and cannot deliver the centrifugal force needed for effective soil or aggregate compaction. Replacing the cylinder and piston as a matched assembly restores the combustion seal, bringing engine output and compaction performance back to where it needs to be.
