The Bomag 05903452 Oil Cooler is a genuine OEM component designed for BW 135 AD, BW 138 AD, BW 138 AC, and BW 138-AD tandem rollers. Sourced directly from Bomag, this oil cooler matches the original specification for a drop-in installation with no guesswork on fitment. It is the correct replacement for operators maintaining their Bomag tandem rollers to the manufacturer's standard.
Key Features
- Genuine OEM Thermal Management Spec — manufactured by Bomag to the same heat-dissipation and flow-rate requirements as the original unit, ensuring the hydraulic system stays within its designed operating temperature range
- Direct-Replacement Fit — engineered to the identical port configuration, bracket mounting points, and line connections as the factory cooler, allowing straightforward installation on affected tandem roller models
- Confirmed Tandem Roller Fitment — compatible with the BW 135 AD, BW 138 AD, BW 138 AC, and BW 138-AD tandem rollers, covering the full BW 135/138 series in this family
- Sustained Hydraulic Performance — a properly functioning oil cooler keeps hydraulic fluid temperatures in check during continuous compaction passes, preventing heat-related power loss, seal degradation, and pump wear
- Verified Part Number Traceability — order with confidence using Bomag part number 05903452, cross-referenced to your machine's parts catalog for an exact match
An oil cooler regulates the temperature of hydraulic fluid circulating through the machine's drive and vibration systems. On a tandem roller operating through extended compaction cycles, hydraulic fluid generates significant heat; the oil cooler dissipates that heat by passing fluid through a core exposed to airflow, keeping temperatures within safe operating limits. When the oil cooler is cracked, clogged, or leaking, fluid overheats rapidly — leading to accelerated wear on pumps, motors, and seals, reduced drive response, and potential shutdown of the hydraulic system entirely.
