The Bomag 05903006 Oil Cooler is a genuine OEM component designed for BW 172 D-2 and BW 142 D-2 single drum rollers. Sourced directly from Bomag, this oil cooler delivers an exact fit with no guesswork on compatibility. It is the correct replacement for operators running either the BW 172 D-2 or BW 142 D-2 single drum roller and needing to restore proper thermal management to the machine's hydraulic or engine oil circuit.
Key Features
- Genuine OEM Thermal Tolerance — built to Bomag's original heat-dissipation specifications, ensuring the cooler handles the thermal load demands of heavy single drum roller operation
- Direct OEM Replacement — mounts to the same brackets and connects to the same lines as the original unit, making the swap straightforward for any qualified technician
- Confirmed Fitment — verified for BW 172 D-2 and BW 142 D-2 single drum rollers, eliminating compatibility uncertainty before the part arrives on site
- Sustained Oil Temperature Control — a functioning oil cooler keeps hydraulic and engine oil within safe operating temperature ranges, protecting pumps, motors, and bearings from heat-induced wear during continuous compaction work
- OEM Part Number Accuracy — supplied under part number 05903006, ensuring you receive the exact Bomag-specified component rather than an approximation
An oil cooler regulates the temperature of hydraulic or engine oil by transferring excess heat to the surrounding air before the oil circulates back through the system. On a heavy single drum roller like the BW 172 D-2 or BW 142 D-2, the hydraulic system is under sustained load throughout the working day, generating significant heat that must be continuously managed. When the oil cooler degrades or fails, oil temperatures climb beyond safe limits, accelerating wear on pumps, control valves, and drive components — and ultimately forcing the machine out of service.
