The Bomag 05903008 Oil Cooler is a genuine OEM component designed for Bomag BW 100, BW 115, and BW 120 tandem rollers. Sourced directly from Bomag, this oil cooler delivers an exact fit for AC-3 and AD-3 variants across the BW 100 AC-3, BW 100 AD-3, BW 115 AC-3, BW 115 AD-3, BW 120 AC-3, and BW 120 AD-3 tandem roller lineup. As a genuine OEM part, it meets the same engineering standards as the original component installed at the factory, so you can install with confidence. Confirm part number 05903008 against your machine's service documentation before ordering to ensure correct application.
Key Features
- Genuine OEM Thermal Management — manufactured to Bomag's original specifications, ensuring the correct flow capacity and heat-rejection performance for your tandem roller's hydraulic and drivetrain oil circuits
- Direct-Fit Replacement — engineered to match the original mounting points and port dimensions, allowing this oil cooler to drop into place on compatible BW-series tandem rollers without modification
- Broad Tandem Roller Coverage — fits BW 100 AC-3, BW 100 AD-3, BW 115 AC-3, BW 115 AD-3, BW 120 AC-3, and BW 120 AD-3 tandem rollers, covering multiple drive and drum variants within the BW 100, BW 115, and BW 120 series
- Sustained Operating Temperature Control — a properly functioning oil cooler keeps hydraulic and drivetrain oil within the correct temperature range, protecting pumps, motors, and bearings from heat-induced wear during continuous compaction cycles
- Part Number Confidence — order by part number 05903008 to ensure you receive the correct Bomag OEM assembly for your specific machine variant
The oil cooler is responsible for dissipating heat from the machine's hydraulic and drivetrain oil before temperatures reach levels that degrade fluid viscosity and accelerate component wear. On tandem rollers like the BW 100, BW 115, and BW 120 series, which rely on hydraulic systems for both propulsion and drum vibration, maintaining proper oil temperature is critical to consistent performance across long paving and compaction shifts. When the oil cooler becomes clogged, leaks, or fails entirely, oil temperatures rise rapidly — leading to sluggish hydraulic response, premature pump and motor wear, and potential machine shutdown if thermal protection systems intervene.
