The Bomag 05903129 Oil Cooler is a genuine OEM component designed for MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers. Sourced directly from Bomag, this oil cooler meets the original engineering specifications for these machines, ensuring a direct, hassle-free installation. Whether you are restoring thermal performance after component failure or completing a scheduled service, part number 05903129 is the correct replacement for these recycler/stabilizer applications.
Key Features
- Genuine OEM Thermal Performance — engineered to Bomag's original heat-dissipation specifications, maintaining proper oil temperature under the high-load demands of recycling and stabilizing work
- Direct Bolt-In Replacement — matches the original mounting points, port locations, and core dimensions of the factory cooler, so installation stays straightforward with existing hardware
- Confirmed Fitment — validated for MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers; verify by referencing part number 05903129 against your machine's service documentation
- Protects Hydraulic and Drive Components — a correctly functioning oil cooler prevents overheating that can accelerate wear on pumps, motors, and bearings throughout the drivetrain
- Authentic Bomag Quality — genuine OEM construction means the core material, fin density, and pressure rating match what BOMAG engineers specified for these MPH-series machines
The oil cooler regulates the temperature of hydraulic or engine oil by transferring heat away from the fluid as it circulates through the cooler core. On heavy recycler/stabilizer machines like the MPH 121 and MPH 122 series, the hydraulic system works under sustained high loads, generating significant heat that must be continuously dissipated to keep oil viscosity and system pressure within the correct operating range. When an oil cooler becomes clogged, corroded, or develops a leak, oil temperatures climb rapidly — leading to accelerated seal degradation, loss of hydraulic efficiency, and potential damage to pumps and motors. Replacing a failed or worn cooler promptly with a genuine OEM unit restores the thermal management the system depends on.
