The Bomag 05729203 Engine Oil Cooler is a genuine OEM component designed for BW-series tandem rollers and single drum rollers, including the BW 100 AD-5, BW 120 AD-5, BW 141 AD-4, BW 154 AD-4, BW 161 AD-4, BW 177 DH-4, and BW 179 DH-4, among others. Sourced directly from Bomag, this engine oil cooler is manufactured to the same specification as the part originally installed at the factory. It installs as a direct replacement with no guesswork, making it the right choice when restoring your roller's cooling and lubrication system to proper working order. Confirm fitment using part number 05729203 against your machine's model and serial number before ordering.
Key Features
- Genuine OEM Thermal Regulation — built to Bomag's exact heat-exchange specification, ensuring the engine oil cooler maintains correct oil temperature under sustained compaction loads
- Direct Drop-In Replacement — matches original mounting points, port sizing, and connection interfaces for a straightforward swap on covered BW tandem and single drum roller models
- Broad BW-Series Coverage — fits an extensive range of BW tandem rollers (including BW 100 AD-5, BW 120 AD-5, BW 120 SL-5, BW 141 AD-4, BW 151 AD-4, BW 154 AD-4, BW 161 AD-4, and BW 161 AC-4 variants) as well as BW 177 and BW 179 single drum roller models
- Engine Protection Where It Counts — a functioning engine oil cooler prevents oil from overheating during long compaction runs; a failed or blocked unit accelerates engine wear and can lead to costly internal damage
- Verified by Part Number 05729203 — cross-reference this number against your Bomag parts manual to confirm compatibility with your specific model and generation before installation
The engine oil cooler transfers heat away from the engine's circulating oil, keeping lubricant viscosity within the range the engine needs to protect bearings, pistons, and other internal surfaces during operation. On heavy compaction equipment like BW-series rollers — which run at sustained load through long paving and grading shifts — maintaining correct oil temperature is critical to engine longevity. When the oil cooler degrades, becomes blocked, or develops a leak, oil temperatures climb, lubrication effectiveness drops, and the risk of accelerated internal engine wear rises significantly.
