The Bomag 05720377 Piston is a genuine OEM piston designed for BPR 65/70 D, BPR 75/60 D-3, BPR 75/60 HD-3, and BPR 70/70 D reversible vibratory plates. Sourced directly from Bomag, this piston meets the exact dimensional and material specifications of the original component. It installs directly into the engine assembly of compatible machines, ensuring a proper fit with no guesswork on tolerances or sizing. If your reversible plate is losing compression or showing signs of engine wear, this is the correct OEM replacement to restore full operating performance.
Key Features
- OEM Compression Integrity — manufactured to Bomag's exact bore diameter and ring-groove specifications, maintaining the compression ratio the engine was designed to deliver
- Direct Engine Replacement — engineered as a drop-in fit for the original piston bore, preserving correct clearances and alignment within the cylinder assembly
- Confirmed Fitment — compatible with BPR 65/70 D, BPR 75/60 D-3, BPR 75/60 HD-3, and BPR 70/70 D reversible vibratory plates
- Sustained Compaction Output — a properly seated piston maintains the power stroke needed to drive consistent vibratory force through the plate, keeping compaction performance where it needs to be
- Genuine Bomag OEM Part — part number 05720377 is an authentic Bomag component, not a generic substitute, so material grade and heat treatment match the original exactly
The piston is a core reciprocating component inside the engine, converting combustion pressure into the crankshaft motion that ultimately powers the exciter mechanism of the vibratory plate. When a piston wears, scores, or loses its ring seal, the engine loses compression, resulting in hard starting, reduced power output, and increased fuel consumption. Replacing a worn piston with a correctly specified OEM part restores proper cylinder sealing and ensures the engine delivers the torque needed to maintain full compaction force across the plate.
