The Multiquip 50311000 Drain Plug M14X1 5 2G40 is a genuine OEM replacement part designed for RW1404 and RW1504 series RAMMAX walk-behind rollers. As a factory-sourced component, part 50311000 is manufactured to the exact thread specification and material grade required for a secure, leak-free seal. Confirmed fitment includes the RW1404, RW1404MR, and RW1504HF models, covering both early and later serial number ranges. DHS Equipment stocks this part to help you get your roller back in service without guesswork.
Key Features
- Genuine OEM Thread Integrity — Manufactured to the exact M14x1.5 thread pitch specified for the 2G40 drain port, ensuring a metal-to-metal seal without cross-threading risk.
- Direct Drop-In Replacement — Matches the original plug geometry and thread profile, seating correctly into the drain port without reworking or additional hardware.
- Broad RAMMAX Roller Compatibility — Verified for RW1404, RW1404MR, and RW1504HF models, including RW1404MR units from S/N 326075 and up and RW1504HF units up to S/N 1534188.
- Leak-Free Fluid Retention — A correctly installed drain plug keeps hydraulic or engine fluid sealed during operation, protecting internal components from contamination and fluid loss.
- Fluid Service Made Simple — Designed for routine oil or fluid changes on your RAMMAX roller, this plug threads in cleanly and torques to spec for repeated service cycles.
A drain plug seals the fluid drain port on an engine, gearbox, or hydraulic system, keeping oil or fluid contained during normal operation and allowing controlled drainage during scheduled service intervals. On RAMMAX walk-behind rollers, a damaged or missing drain plug can lead to rapid fluid loss, internal component wear, and potential seizure of drivetrain or hydraulic systems. Replacing a worn or cross-threaded plug with the correct OEM specification part — matching thread pitch, diameter, and material — is essential to maintaining a reliable seal across repeated service cycles.
