Key Features
- Genuine OEM Filtration Integrity — Manufactured to the same hydraulic filtration standards as the original, ensuring consistent contamination control in the return circuit.
- Direct-Fit Assembly — Engineered as a complete assembly with correct port sizing and mounting configuration for drop-in installation on compatible RW-series rollers.
- Confirmed Fitment — Verified for RW1403HF, RW1404, and RW1404MR models, including RW1404MR units from S/N 326075 and up.
- Protects Hydraulic System Components — A functioning return filter traps wear particles and contaminants before they cycle back through the hydraulic circuit, extending the service life of pumps, motors, and valves.
- Hydraulic System Safety — A failed or bypassed return filter allows contaminated fluid to circulate freely, accelerating component wear and increasing the risk of hydraulic system failure during operation.
The return filter assembly sits in the hydraulic return line, capturing contaminants and particulates in the fluid as it cycles back to the reservoir after passing through the system. Keeping this filter clean and in good condition is critical to maintaining hydraulic fluid quality across pumps, motors, and control valves. When the filter becomes clogged or the assembly fails, unfiltered fluid recirculates through the system, causing accelerated wear and potential damage to costly hydraulic components.
