The Bomag 05903081 Oil Cooler is a genuine OEM component designed for BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 145 PDH-3, BW145D 3, BW145PDH 3, C 825 C, and BW 145-DH-3 single drum rollers. As a direct OEM replacement sourced from Bomag, this oil cooler is built to the exact specifications required by your machine — no guesswork on compatibility. It installs directly into the cooling circuit in place of the original unit, ensuring a correct, secure fit every time. If your current oil cooler is leaking, clogged, or no longer holding temperature, this is the part that restores your machine to full working condition.
Key Features
- Genuine OEM Thermal Precision — manufactured to Bomag's exact heat-exchange specifications, ensuring the oil cooler maintains proper hydraulic and engine oil temperatures under full working loads on your single drum roller.
- Direct OEM Replacement Fit — engineered to match the original mounting points, port connections, and core dimensions of the factory unit, allowing straightforward installation with no adaptation.
- Broad Single Drum Roller Coverage — confirmed fitment across BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW145D 3, BW145PDH 3, BW 145-DH-3, and C 825 C single drum rollers.
- Sustained Hydraulic System Health — a properly functioning oil cooler keeps hydraulic fluid within its safe operating range, protecting pumps, motors, and control valves from heat-related wear and premature failure.
- Leak-Free Reliability — genuine OEM construction means consistent core integrity and seal compatibility, reducing the risk of oil loss or pressure drop that can compromise drivetrain and vibratory system performance.
The oil cooler is a critical component in the machine's thermal management system, responsible for dissipating heat from the hydraulic or engine oil as it circulates through the drivetrain and vibratory systems. On a single drum roller working in demanding compaction conditions, oil temperatures can rise rapidly — the cooler keeps those temperatures within a safe operating range, protecting sensitive components like hydraulic pumps and control valves from accelerated wear. When the oil cooler fails or becomes restricted, fluid temperatures climb, efficiency drops, and the risk of costly system damage increases significantly.
