The Bomag 05904142 Oil Cooler is a genuine OEM component designed for Bomag BW 161 AD-5, BW 161 AC-5, BW 161 ADO-5, BW 190 AD-5, BW 190 ADO-5, and BW 202 AD-5 tandem rollers. Sourced directly from Bomag, this oil cooler meets the exact design and material specifications of the original part it replaces. It drops into place as a direct OEM replacement, ensuring correct fitment across the full range of compatible BW-series tandem rollers. When thermal management matters on the job, trusting a genuine Bomag part number 05904142 is the straightforward call.
Key Features
- Genuine OEM Thermal Performance — manufactured to Bomag's original heat-dissipation specifications, maintaining proper hydraulic and engine oil temperatures under sustained compaction loads
- Direct OEM Replacement — mounts to the existing brackets and connections on compatible BW-series tandem rollers with no adaptation needed to fittings or mounting points
- Broad Tandem Roller Coverage — confirmed fit for BW 161 AD-5, BW 161 AC-5, BW 161 ADO-5, BW 190 AD-5, BW 190 ADO-5, and BW 202 AD-5 tandem rollers
- Protects Critical Drivetrain Components — a properly functioning oil cooler prevents heat buildup that accelerates wear on hydraulic pumps, motors, and bearings throughout the machine
- Hydraulic System Integrity — correct operating oil temperature maintains hydraulic fluid viscosity within design range, preserving pressure consistency and drive responsiveness on the drum and propulsion circuits
The oil cooler regulates the temperature of hydraulic and engine oil by transferring excess heat to the surrounding air as fluid circulates through its core. On ride-on tandem rollers like the BW 161 and BW 202 series, the hydraulic system works continuously to drive the drums and vibration circuits, generating significant heat under sustained use. When the oil cooler degrades or fails, fluid temperatures rise beyond design limits, which can cause accelerated seal wear, reduced hydraulic efficiency, and eventual damage to pumps and motors — making timely replacement essential to keeping the machine productive and protected.
