The Bomag 05546337 Control Piston is a genuine OEM component designed for Bomag BC-series refuse/landfill compactors and soil compactors, covering a wide range of models including the BC 671 RB, BC 771 RB, BC 772 RS, BC 462 EB, BC 472 RB, BC 473 RB-4, and many more generation variants. Sourced directly from Bomag, this control piston matches the original part in every critical dimension, ensuring it seats and operates exactly as the factory intended. It is a direct replacement for part number 05546337 across the full lineup of compatible BC-series machines, eliminating guesswork and fitment uncertainty at the time of service.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact tolerances for hydraulic control circuits, ensuring consistent spool travel, pressure response, and flow regulation in demanding compaction applications.
- Drop-In Replacement — machined to the original bore and port dimensions so this piston installs directly into the existing valve or cylinder housing without rework or resealing of unrelated components.
- Broad BC-Series Coverage — fits Bomag refuse/landfill compactors including the BC 671 RB, BC 771 RB, BC 772 RB, BC 772 RS, BC 572 RB-2, BC 473 RB-4, BC 473 RS-4, and BC 672 RB-4, as well as soil compactors including the BC 462 EB, BC 772 EB-2, BC 672 EB-2, and BC 473 EB-4.
- Consistent Hydraulic Control — a correctly functioning control piston maintains accurate directional and pressure control within the hydraulic system; a worn or damaged piston causes sluggish response, pressure loss, or unintended drift that compromises compaction output.
- Verified Bomag Part Number — ordering by OEM part number 05546337 confirms you are receiving the correct component for your machine generation, from RB and RS refuse compactors to EB soil compactors across multiple production series.
The control piston is a precision-machined hydraulic component that regulates the direction and volume of fluid flow within a hydraulic valve or actuator assembly. On heavy BC-series compactors, it plays a central role in managing drive, steering, or implement control circuits — maintaining the operator's ability to direct machine movement and compaction force accurately. When a control piston wears, corrodes, or fails, the result is typically erratic hydraulic behavior, loss of responsiveness, or internal leakage that forces unplanned downtime and risks further damage to surrounding hydraulic components.
