The Bomag 05660377 Pressure Spring is a genuine OEM component designed for a wide range of Bomag walk-behind/light rollers, tandem rollers, cold milling machines, and trench compactors. As a factory-sourced part, this pressure spring delivers the exact tension, material grade, and dimensional tolerances specified for your machine — no guesswork on compatibility. Confirmed fitment includes the BW 60 S, BW 65 S, BW 65 HS, BW 65 S-2, BW 75 S, BW 75 S-2, and BW 90 S walk-behind/light rollers; BW 174 AP-4, BW 174 AP-4 AM, BW 174 AP-4 PB, BW 174 AP-4 AM PB, BW 174 AP-4i, BW 174 AP-4i AM, BW 174 AP-4f, BW 174 AP-4f AM, BW 174 AP-4v AM, BW 174 APO-4i, BW 174 APO-4f, BW 174 ACP 4I AM, BW 174 AP-5, and BW 174 ACP-5 AM tandem rollers; BM 500/15, BM 500/15 EU-Flex, BM 500 15 P8, BM 600/15, BM600 /15, BM 600/15 EU-Flex, and BM 600/15 EU-Flex T4i cold milling machines; and BW 35 and BW 35 W trench compactors. Ordering by part number 05660377 ensures you receive the correct OEM spring the first time.
Key Features
- OEM Spring Rate and Material Grade — sourced directly from Bomag, this pressure spring meets the exact coil tension and steel specification required for consistent, repeatable performance in your application
- Drop-In Replacement — dimensionally identical to the original, this spring seats and loads correctly without rework or shimming, so your machine returns to service quickly
- Broad Confirmed Fitment — covers Bomag walk-behind/light rollers including the BW 60 S and BW 75 S-2, BW 174-series tandem rollers, BM 500/15 and BM 600/15 cold milling machines, and BW 35 trench compactors
- Consistent Clamping and Actuation Force — a correctly rated pressure spring maintains the designed load on valves, levers, or actuating mechanisms; a fatigued or broken spring leads to erratic engagement, fluid bypass, or control loss
- Genuine Bomag Part — supplied as genuine OEM under part number 05660377, ensuring traceability and compatibility across every machine variant in the fitment range
A pressure spring stores and releases mechanical energy to maintain a set clamping, seating, or return force on a valve, linkage, or actuating component within the machine. When the spring is correctly rated, the mechanism it loads engages and releases at the designed threshold — keeping fluid flow, control response, or mechanical engagement predictable and consistent. When a pressure spring fatigues, takes a set, or breaks, that load is lost: valves may fail to seat fully, controls can feel spongy or unresponsive, and fluid or mechanical systems can behave erratically, leading to accelerated wear on surrounding components. Replacing a worn spring with the correct OEM part restores the original operating characteristics and protects the components that depend on it.
