The Multiquip 66405 Hydraulic Hose is a genuine OEM component designed for RAMMAX walk-behind roller models including the RW1404MR, RW1504HF, and P33/24. This single-end hose is engineered to OEM specification, ensuring correct pressure rating, end fitting geometry, and hose length for a direct installation with no rework required. Compatible with RW1404MR units from S/N 326075 and up, RW1504HF units up to S/N, and the P33/24 HHMR-BD with blade configuration, this part is the correct choice when you need to restore hydraulic integrity to your roller. Sourced directly through authorized Multiquip supply channels, the 66405 carries the same quality assurance as the original production part.
Key Features
- OEM-Grade Hose Construction — Built to match the original burst pressure rating and hose diameter, ensuring the hydraulic circuit performs as designed without leaks or pressure loss.
- Single-End Fitting Configuration — One-end swaged fitting matches the original port connection on RAMMAX roller hydraulic systems for a straightforward swap.
- Confirmed Roller Fitment — Verified for RW1404MR (S/N 326075 and up), RW1504HF (up to S/N 1534188), and P33/24 HHMR-BD with blade.
- Maintains Full Hydraulic Pressure — A worn or cracked hose causes pressure drop that directly reduces compaction force and drum drive response; replacing with 66405 restores full system output.
- Hydraulic System Safety — A failed high-pressure hose poses a fluid injection hazard to operators. Using the correct OEM replacement hose maintains safe operating pressure containment on the hydraulic circuit.
A hydraulic hose carries pressurized fluid between the pump, control valves, and drive or vibration motors on walk-behind rollers. When the hose is intact and correctly routed, it allows the operator to transfer precise hydraulic power to the drum drive and compaction system. If the hose cracks, swells, or develops a pinhole leak, the machine loses hydraulic pressure, resulting in sluggish or failed drum movement, reduced compaction output, and a potential safety hazard from high-pressure fluid spray. Replacing a damaged hose with the correct OEM part restores full system pressure and protects downstream components from cavitation and contamination.
