The Bomag 05903123 Oil Cooler is a genuine OEM component designed for BC 972 RB, BC 1172 RB, BC 972 RB-2, and BC 1172 RB-2 refuse and landfill compactors. Sourced directly from Bomag, this oil cooler meets the exact design and material specifications of the original unit installed at the factory. This part installs directly in place of the factory component, restoring proper thermal regulation to the hydraulic or engine oil circuit with no guesswork on fitment. Operators running any of these BC-series refuse compactors can order with confidence knowing part number 05903123 is the correct, verified replacement.
Key Features
- OEM Thermal Performance — engineered to maintain the precise heat-dissipation capacity required by high-demand refuse compactor hydraulic and engine systems, ensuring oil temperatures stay within the operating range Bomag specifies for these machines
- Direct-Fit Replacement — matches the original mounting configuration, port sizing, and core dimensions of the factory oil cooler for a straightforward swap on BC 972 RB, BC 1172 RB, BC 972 RB-2, and BC 1172 RB-2 compactors
- Broad BC-Series Coverage — a single part number 05903123 covers four refuse and landfill compactor variants: BC 972 RB, BC 1172 RB, BC 972 RB-2, and BC 1172 RB-2
- Protects Critical Drive Components — a properly functioning oil cooler prevents overheating that can accelerate wear on hydraulic pumps, motors, and engine bearings, extending the service life of your compactor's drivetrain
- Genuine Bomag OEM Part — supplied as an authorized Bomag replacement, this component carries the same part traceability and quality assurance as the unit your machine shipped with
An oil cooler regulates the temperature of engine oil or hydraulic fluid by transferring excess heat to the ambient air or coolant circuit before the oil returns to the system. In heavy refuse and landfill compactors like the BC 972 RB and BC 1172 RB, these machines work under sustained high loads — compacting dense waste material for extended cycles — which generates significant heat in the hydraulic system. When the oil cooler degrades or fails, oil temperatures climb beyond safe limits, accelerating seal wear, reducing hydraulic efficiency, and risking damage to pumps and valves. Replacing a worn or leaking oil cooler promptly with the correct OEM part keeps the hydraulic system operating within its designed temperature range and protects downstream components from heat-related failure.
