The Bomag 05903193 Hydraulic Oil Cooler is a genuine OEM component designed for BW 80 AD-2, BW 80 ADS, BW 90 AC-2, and BW 90 AD-2 tandem rollers. Sourced directly from Bomag, this hydraulic oil cooler meets the exact specifications set for these machines, ensuring a correct, trouble-free installation. If you're maintaining or restoring one of these compact tandem rollers, this is the correct OEM replacement to keep the hydraulic system running within its designed operating temperature range.
Key Features
- Genuine OEM Thermal Management — built to Bomag's exact heat-exchange specifications, ensuring the hydraulic oil cooler dissipates heat at the rate the system was engineered to handle
- Direct-Fit Replacement — matches the original mounting points, port sizes, and connection interfaces on compatible tandem rollers for a straightforward swap
- Confirmed Tandem Roller Fitment — verified for BW 80 AD-2, BW 80 ADS, BW 90 AC-2, and BW 90 AD-2 tandem rollers
- Sustained Hydraulic Performance — proper oil cooling keeps hydraulic fluid viscosity stable, protecting pumps, motors, and valves from heat-related wear and maintaining consistent drive and vibration output
- System Protection — a failing hydraulic oil cooler allows fluid temperatures to climb unchecked, accelerating seal degradation and risking pump damage; replacing it promptly safeguards the entire hydraulic circuit
The hydraulic oil cooler is responsible for drawing heat out of the hydraulic fluid as it circulates through the machine's drive and vibration systems. By keeping fluid temperature within the correct operating range, it preserves fluid viscosity and protects seals, pumps, and valves from thermal stress. When the cooler becomes blocked, corroded, or damaged, hydraulic temperatures rise, performance drops, and internal components begin to degrade — making timely replacement essential to keeping the machine operating at full capacity.
