The Bomag 05903270 Oil Cooler is a genuine OEM component designed for Bomag BW 141 AD-4, BW 154 AD-4, BW 151 AD-4 AM, BW 151 AC-4 AM, and related tandem roller variants. Sourced directly from Bomag, this oil cooler delivers the exact specifications your machine was built around, ensuring a correct, trouble-free installation. It is engineered to perform in the demanding thermal environment of ride-on tandem rollers, where consistent oil temperature control is critical to drivetrain and hydraulic system longevity. Confirm your model against the fitment list — this part covers the BW 141 AD-4, BW 141 AD-4 AM, BW 151 AD-4 AM, BW 151 AC-4 AM, BW 154 AD-4, and BW 154 AD-4 AM tandem rollers.
Key Features
- Genuine OEM Thermal Precision — manufactured to Bomag's exact core capacity and flow-rate specifications for tandem roller hydraulic and drivetrain oil circuits, ensuring the cooler handles real operating heat loads without compromise.
- Direct Drop-In Replacement — mounting points, inlet and outlet ports, and overall dimensions match the original unit exactly, allowing straightforward removal and reinstallation with no rework or adapter fittings.
- Broad Tandem Roller Coverage — fits the BW 141 AD-4, BW 141 AD-4 AM, BW 151 AD-4 AM, BW 151 AC-4 AM, BW 154 AD-4, and BW 154 AD-4 AM, as well as the BW 154 AD-4 AM variant, covering a wide range of Bomag ride-on tandem rollers.
- Protects Hydraulic and Drive Components — a properly functioning oil cooler keeps fluid temperatures within operating range, preventing viscosity breakdown that accelerates wear on pumps, motors, and bearings throughout the machine.
- Verified Part Number Traceability — ordering by Bomag part number 05903270 eliminates guesswork and ensures you receive the correct cooler for your specific machine configuration the first time.
The oil cooler transfers heat away from the hydraulic and drivetrain oil as it circulates through the machine, keeping fluid temperatures within the range where the oil maintains its protective properties. On ride-on tandem rollers like these BW-series machines, the hydraulic system powers the drums, steering, and vibration circuits simultaneously, generating substantial heat during extended paving and compaction runs. When the oil cooler degrades or fails — through core damage, internal scaling, or leaks — fluid temperatures climb, accelerating wear across every component the oil lubricates and potentially leading to hydraulic system failure mid-operation.
