The Bomag 05903126 Oil Cooler is a genuine OEM component designed for Bomag BW 124 and C 815 series single drum rollers. Sourced directly from Bomag, this oil cooler meets the exact specifications of the original unit it replaces, ensuring a correct, trouble-free installation. This component is confirmed to fit the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, BW124DH 4, BW124PDH 3, BW124PDH-40, C 815 C, and C815D single drum rollers. When your roller's cooling system needs attention, replacing a worn or failed oil cooler with an authentic Bomag part keeps the hydraulic and engine oil temperatures within operating range and protects the drivetrain components that depend on properly cooled fluid.
Key Features
- Genuine OEM Cooling Efficiency — manufactured to Bomag's original design specifications, delivering the same core capacity and flow characteristics as the unit that came off the production line
- Direct-Fit Replacement — matches the original mounting ports, bracket points, and line connections of the BW 124 and C 815 series, allowing straightforward installation without modification
- Broad Single Drum Roller Coverage — confirmed for the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, C 815 C, C815D, and related variants
- Protects Critical Drivetrain Components — maintaining proper oil temperatures prevents premature wear on hydraulic pumps, motors, and bearings that are vulnerable to heat-degraded fluid
- Verified Bomag Part Number — order with confidence using part number 05903126, cross-referenced against Bomag's OEM catalog for fitment accuracy
The oil cooler is responsible for dissipating heat from the engine or hydraulic oil as it circulates through the roller's systems. On a single drum roller operating under sustained load — compacting soil in repeated passes — hydraulic fluid temperatures can rise quickly, and an effective oil cooler keeps that heat in check to maintain consistent viscosity and lubrication. When the oil cooler becomes clogged, corroded, or develops a leak, oil temperatures climb, fluid degrades faster, and hydraulic components begin to wear prematurely, which can eventually lead to system failure and unplanned downtime on the job.
