The Bomag 05720378 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 original engineering specifications for these machines, giving you confidence that it will seat, seal, and perform exactly as the factory intended. This piston fits all four reversible vibratory plate models listed above, making it a straightforward service solution when an engine rebuild or top-end repair is on the schedule.
Key Features
- Genuine OEM Precision — manufactured to Bomag's original dimensional tolerances for correct ring groove depth, skirt profile, and bore clearance — critical details for a piston operating under high compression cycling
- Direct Engine Swap — this piston installs as a drop-in replacement with no machining or adaptation, matching the original bore diameter and pin dimensions of the host engine
- Broad Reversible Plate Coverage — fits the BPR 65/70 D, BPR 75/60 D-3, BPR 75/60 HD-3, and BPR 70/70 D, covering the full range of these heavy-duty diesel reversible vibratory plates
- Compression Integrity Restored — a worn or scored piston causes misfires, power loss, and excessive oil consumption; replacing it with part number 05720378 restores full compression and engine output
- Fuel System Safety — correct piston fit prevents combustion blowby into the crankcase, reducing the risk of oil contamination and uncontrolled pressure buildup in the engine
The piston is the reciprocating heart of the engine, converting combustion pressure into the mechanical force that ultimately drives the plate's exciter shaft and vibratory compaction output. When a piston wears, cracks, or loses its ring seal, combustion gases bypass into the crankcase, oil burns off, and the engine loses the power needed to maintain proper compaction force. Replacing a failed piston promptly keeps the engine running at rated output and prevents secondary damage to cylinder walls, rings, and bearings.
