The Multiquip 50140400 is a genuine OEM Drain Plug 4M40L Hatz designed for RAMMAX walk-behind roller models RW1404, RW1404MR, and RW1504HF. As a factory-sourced component, part 50140400 is manufactured to the exact specifications required by the Hatz 4M40L engine found in these machines. Confirmed fitment covers the RW1404, RW1404MR (including serial number 326075 and up), and RW1504HF (up to serial number ), making it straightforward to verify compatibility before ordering. Trust DHS Equipment to supply the correct OEM part the first time.

Key Features

  • Genuine OEM Sealing Integrity — Manufactured to the precise thread pitch and seat geometry of the Hatz 4M40L engine, ensuring a leak-free seal under operating temperatures and pressures.
  • Direct-Fit Installation — Threads directly into the OEM drain port on the 4M40L engine with no reworking of the drain boss or use of adapters.
  • Confirmed Roller Compatibility — Verified fitment for RW1404, RW1404MR, and RW1504HF RAMMAX walk-behind rollers across the listed serial number ranges.
  • Engine Oil System Protection — A correctly seated drain plug maintains proper oil containment, protecting the Hatz engine from oil loss, overheating, and internal wear during operation.
  • Fuel and Fluid Safety Compliance — A failed or cross-threaded drain plug risks uncontrolled oil release; using the correct OEM replacement eliminates that risk and keeps the machine operating within safe parameters.

The drain plug seals the oil drain port at the base of the engine crankcase, allowing the engine oil to be fully retained during operation and cleanly drained during scheduled oil changes. On the Hatz 4M40L engine, the plug must match the thread specification of the drain boss precisely — an incorrect or worn plug can strip the threads, cause oil leaks, or lead to undetected oil loss that results in accelerated engine wear. Replacing the drain plug with the correct OEM part at each service interval is a simple step that protects a significantly more expensive engine investment.
