The Bomag 05903084 Oil Cooler is a genuine OEM component designed for BW 124 and C 815 C series single drum rollers. As a direct OEM replacement, this oil cooler is manufactured to the same specifications as the original unit, ensuring correct fitment across covered BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, and C 815 C variants. Sourced directly from Bomag, part number 05903084 delivers the confidence of an exact fit with no guesswork on compatibility. Keeping the hydraulic and engine oil temperatures in check is essential to sustained compaction output, and this cooler is built to restore that protection correctly.
Key Features
- Genuine OEM Thermal Integrity — manufactured to Bomag's original heat-exchange specifications, ensuring the cooler maintains correct oil temperature thresholds under sustained compaction load
- Exact-Match Replacement — engineered to mount and connect identically to the original unit, with matching port sizing and bracket geometry for a straight swap
- Broad BW 124 and C 815 C Coverage — confirmed fitment across BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH-40, C 815 C, and additional single drum roller variants in this family
- Protects Against Thermal Overload — a degraded or leaking oil cooler allows hydraulic and engine oil temps to climb, accelerating component wear across the drive and vibration systems; this replacement restores full thermal regulation
The oil cooler regulates the temperature of hydraulic and engine oil by dissipating heat generated during operation. On single drum rollers like the BW 124 and C 815 C, where the vibration system and drive circuits run under continuous load, maintaining stable oil temps is critical to protecting pumps, motors, and valves from heat-related wear. When the oil cooler becomes blocked, corroded, or develops a leak, oil temperatures rise beyond safe limits, leading to accelerated component degradation and potential system failure. Replacing a worn cooler with the correct Bomag OEM unit restores the machine's thermal management to its original operating standard.
