The Bomag 05728022 Cylinder and Piston is a genuine OEM component designed for the BMP 851 trench compactor. Sourced directly from Bomag, this cylinder and piston assembly matches the original equipment specification — ensuring a correct, no-compromise fit in your machine. If your BMP 851 is losing compaction force or showing signs of internal wear, replacing this assembly with the authentic OEM part restores the unit to its original operating condition.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original tolerances for the cylinder bore and piston dimensions, preserving the compression characteristics the BMP 851 was engineered to deliver
- Direct-Fit Replacement — matches the original mounting configuration and interface dimensions of the BMP 851, allowing straightforward installation without modification
- Confirmed BMP 851 Fitment — verified for the BMP 851 trench compactor; always cross-reference part number 05728022 against your machine's serial number before ordering
- Restored Compaction Output — a worn cylinder or piston reduces impact energy and compaction effectiveness; this assembly brings the vibratory drive system back to full rated output
- Long-Term Internal Integrity — OEM-grade material and surface finish on the cylinder wall resist accelerated wear, helping maintain consistent performance across the service interval
The cylinder and piston assembly is the heart of the vibratory drive system in a trench compactor, converting engine power into the rapid reciprocating impacts that compact soil in trenches and confined areas. The piston moves within the cylinder under hydraulic or mechanical force, generating the percussive energy that gives the machine its compaction capability. When the cylinder bore wears or the piston loses its sealing integrity, impact force drops noticeably — leaving soil insufficiently compacted and the machine working harder than it should. Replacing a worn assembly promptly with part number 05728022 restores full compaction performance and prevents secondary damage to surrounding components.
