The Multiquip 40068600 Controller Glow RW1404 2040 is a genuine OEM component designed for RW1404, RW1404MR, and RW1504HF series RAMMAX walk-behind rollers. As a direct Multiquip OEM part, 40068600 is manufactured to the same specification as the original, ensuring a correct installation with no adaptation required. This part fits RW1404MR units at serial number 326075 and up, as well as RW1504HF units up to serial number, making serial number verification an important step before ordering.
Key Features
- Genuine OEM Electrical Specification — Built to the original output and resistance parameters for the glow control circuit, ensuring the controller signals correctly under cold-start conditions.
- Direct Drop-In Replacement — Matches the original mounting configuration and wiring connections on the RW1404 and RW1404MR roller platforms for a straightforward swap.
- Confirmed Fitment — Compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) RAMMAX rollers — verify your serial number before ordering.
- Cold-Start Reliability — A functioning glow controller delivers timed pre-heat to the engine's glow plugs, allowing the diesel to fire cleanly in cold or low-temperature conditions. A failed controller leads to hard starts or no-start situations.
- Fuel System and Electrical Safety — Correct glow control timing prevents excessive cranking and unburned fuel accumulation in the combustion chamber, protecting both the engine and the operator.
The glow controller manages the timing and duration of electrical current sent to the engine's glow plugs before and during cold starts. On diesel-powered equipment like the RW1404 and RW1504HF rollers, glow plugs pre-heat the combustion chamber to allow reliable ignition without the aid of a spark. When the controller fails, the glow plugs may not activate at all, resulting in hard starting, excessive white smoke, or a complete no-start condition — particularly in cooler ambient temperatures. Replacing a worn or failed controller with a genuine Multiquip OEM part restores proper pre-heat sequencing and protects the engine from the wear caused by prolonged cold cranking.
