Bomag 05729373 Piston

The Bomag 05729373 Piston is a genuine OEM component designed for Bomag BM 2000/60 and BM 2000/60-2 cold milling machines, BC-series refuse/landfill compactors and soil compactors, and MPH 122-2 and MPH 125 recycler/stabilizers. Sourced directly from Bomag, this piston meets the exact specifications required for these demanding heavy-equipment applications. Confirmed fitment includes the BC 672 RB-2, BC 772 RB-2, BC 972 RB-2, BC 1172 RB-2, BC 772 RS-2, BC 672 EB-2, and BC 772 EB-2. When your machine calls for part number 05729373, this is the correct, factory-authorized component to install.

Key Features

• Genuine OEM Dimensional Accuracy — manufactured to Bomag's exact bore diameter, ring groove depth, and crown profile tolerances, ensuring correct compression and seal performance in heavy-duty hydraulic and engine applications
• Direct Drop-In Replacement — machined to match the original piston geometry so this component seats and functions correctly without reworking bores or mating components
• Broad Heavy-Equipment Coverage — fits BM 2000/60 and BM 2000/60-2 cold milling machines, BC 672 RB-2, BC 772 RB-2, BC 772 RS-2, BC 972 RB-2, BC 1172 RB-2 refuse/landfill compactors, BC 672 EB-2 and BC 772 EB-2 soil compactors, and MPH 122-2 and MPH 125 recycler/stabilizers
• Sustained Power Output — a correctly fitted piston maintains proper compression or hydraulic force, keeping the machine operating at rated power; a worn or failed piston leads to loss of pressure, reduced output, and accelerated wear on cylinder walls and seals
• Fuel System Integrity — in engine applications, an OEM-spec piston preserves the correct combustion chamber volume, supporting proper fuel metering and preventing excessive emissions or fuel consumption caused by piston slap or blow-by

A piston transfers force within a cylinder — either converting combustion pressure into mechanical motion in an engine, or transmitting hydraulic fluid pressure in a hydraulic system. It must maintain a tight, consistent seal against the cylinder wall to prevent blow-by or pressure loss. When a piston wears, cracks, or develops scoring, the result is lost compression or hydraulic pressure, sluggish machine response, increased fluid or fuel consumption, and potential damage to surrounding components. Replacing a failed piston with a genuine OEM part like the Bomag 05729373 restores the original pressure ratings and protects the integrity of the entire cylinder assembly.
