The Bomag 05887258 Pressure Regulator is a genuine OEM component designed for BW 170 AD, BW 174 AD, and BW 174 AD AM tandem rollers. Sourced directly from Bomag, this pressure regulator delivers an exact fit and is built to the same specifications as the original part installed at the factory. This part is the correct direct replacement for these tandem roller models, giving you confidence in compatibility before the part ever arrives on your jobsite.
Key Features
- Genuine OEM Hydraulic Precision — manufactured by Bomag to maintain the exact pressure thresholds required for consistent hydraulic circuit performance in tandem rollers
- Direct-Fit Replacement — engineered to install in the same position and connect to the same hydraulic lines as the original, with no adaptation or reworking of fittings
- Confirmed Fitment — validated for Bomag BW 170 AD, BW 174 AD, and BW 174 AD AM tandem rollers
- Stable System Pressure — a correctly functioning pressure regulator holds hydraulic pressure within the designed operating range, protecting downstream components from pressure spikes and maintaining drive and vibration performance
- Hydraulic Safety Assurance — a failing pressure regulator can allow uncontrolled pressure buildup or pressure loss in the hydraulic circuit, creating unsafe operating conditions and potential damage to pumps and motors; replacing it promptly keeps the system operating within safe limits
A pressure regulator controls and limits hydraulic fluid pressure within a circuit, acting as the system's gatekeeper to ensure pressure stays within the designed operating range. On tandem rollers like the BW 170 AD and BW 174 AD, where hydraulic systems power both propulsion and drum vibration, a properly calibrated pressure regulator is essential for smooth, consistent machine behavior. When this component wears or fails, operators may notice erratic drive response, loss of vibration output, or audible stress on hydraulic components — all signs that the regulator is no longer holding pressure correctly.
