The Multiquip 50163900 Glow Plug 184G Rw-1404 2G40 is a genuine OEM component designed for RW1404, RW1404MR, and RW1504HF RAMMAX walk-behind rollers. As a direct OEM replacement, this glow plug is manufactured to the exact output and resistance specifications required by the diesel engines in this roller family, ensuring correct cold-start performance on every use. Verified fitment covers the RW1404, RW1404MR, and RW1504HF (up to S/N ), making part number 50163900 the correct choice for these machines. Source it through DHS Equipment for confidence in authenticity and accuracy.
Key Features
- OEM-Correct Heating Output — Built to the precise electrical resistance and tip temperature specification required by the diesel engine in this roller series, not a generalized universal spec.
- Drop-In Thread and Connector Match — Installs directly into the existing glow plug port with no rework to wiring harness or plug seating needed.
- Confirmed Fitment — Verified for RW1404, RW1404MR, and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
- Dependable Cold-Start Performance — A correctly functioning glow plug pre-heats the combustion chamber so the diesel engine fires cleanly in cold or damp conditions; a worn plug leads to hard starts, white smoke, and misfires.
- Genuine Multiquip OEM Part — Supplied under the original Multiquip part number 50163900, backed by the manufacturer's OEM sourcing standards.
A glow plug is a resistive heating element threaded directly into the diesel engine's cylinder head. Before and during startup, it heats the precombustion or combustion chamber to a temperature high enough for the diesel fuel-air mixture to ignite reliably without a spark. When a glow plug weakens or fails, the engine becomes difficult or impossible to start in cool conditions, and operators may notice excessive white or gray exhaust smoke during warmup. Replacing a worn glow plug with the correct OEM unit restores clean, dependable starting and protects the engine from the stress of repeated failed start attempts.
