The Multiquip 51612 Return Filter Complete RW-1800 P35K/2B/4B is a genuine OEM hydraulic return filter assembly designed for P35K and RW-1800 series RAMMAX ride-on rollers. As a direct OEM replacement, this complete filter assembly ships with all necessary components to restore the hydraulic return circuit to proper operating condition without sourcing individual sub-parts. Verified for compatibility with P35K and RW-1800 models, including 2B and 4B size variants, this part ensures the hydraulic system stays clean and protected under the demanding conditions of asphalt and compaction work.
Key Features
- Genuine OEM Hydraulic Filtration — Manufactured to Multiquip's exact media and flow specifications, ensuring the return circuit receives the correct filtration efficiency for hydraulic fluid protection.
- Complete Assembly — Supplied as a full return filter assembly, so every component of the filter unit is replaced together for a thorough, reliable service.
- Confirmed Fitment for RAMMAX Rollers — Engineered specifically for P35K and RW-1800 series ride-on rollers, including 2B and 4B configurations.
- Protects Hydraulic System Components — A functioning return filter keeps contaminants out of control valves, pumps, and cylinders — preventing costly internal wear across the entire hydraulic circuit.
- OEM Part 51612 — Sourced directly from Multiquip, eliminating guesswork on fitment and ensuring correct installation on supported models.
The return filter in a hydraulic system captures particulate contamination as fluid cycles back from the actuators and motors to the reservoir. Keeping this filter in good condition is critical — a clogged or bypassing return filter allows metal particles and debris to recirculate through the hydraulic circuit, accelerating wear on pumps, valves, and drive components. On a ride-on roller like the RW-1800 or P35K, where hydraulic pressure controls both propulsion and vibration functions, a clean return filter is essential to consistent machine performance and long-term system health.
