The Bomag 05729366 Piston is a genuine OEM piston designed for Bomag recyclers/stabilizers and refuse/landfill compactors, including the MPH 122-2, MPH 125, BC 772 RB-2, BC 672 RB-2, BC 772 RS-2, BC 972 RB-2, BC 1172 RB-2, BC 772 EB-2, and BC 672 EB-2. Sourced directly from Bomag, this piston meets the same specifications as the original component it replaces, ensuring correct fitment and function across all compatible machines. When engine or hydraulic performance begins to suffer, replacing the worn piston with part number 05729366 restores proper compression and keeps these heavy-duty machines working at full capacity.
Key Features
- Genuine OEM Compression Integrity — manufactured to Bomag's original dimensional and material tolerances, delivering consistent ring seal and bore compatibility that aftermarket substitutes may not match
- Direct-Fit Replacement — this piston installs into the original bore without modification, preserving correct stroke geometry and clearances
- Broad Machine Coverage — confirmed fitment across Bomag MPH 122-2 and MPH 125 recyclers/stabilizers, BC 672 RB-2, BC 772 RB-2, BC 772 RS-2, BC 972 RB-2, and BC 1172 RB-2 refuse/landfill compactors, and BC 672 EB-2 and BC 772 EB-2 soil compactors
- Restored Compression and Power Output — a correctly seated piston maintains the combustion seal needed for full engine power; a worn or cracked piston causes blow-by, oil consumption, and loss of working force
- Long-Term Durability Under Heavy Load — built to handle the high-cycle demands of large compaction and stabilization equipment operating continuously in demanding site conditions
A piston is a core reciprocating component inside the engine cylinder, converting the force of combustion into the crankshaft rotation that drives the machine. It must maintain a tight seal against the cylinder wall to preserve compression; if the piston wears, cracks, or scores, combustion gases escape past the rings, leading to reduced power, increased oil consumption, and eventual engine failure. Replacing a damaged piston promptly with a genuine OEM part like the Bomag 05729366 is the most direct way to restore full engine performance and protect the surrounding components from secondary damage.
