The Multiquip 50262 Key 1/4 Inch x 25 MM is a genuine OEM component designed for RW1404MR, RW1504HF, MVH408DZ, MVH308DZ, and EM900SD equipment. As a direct OEM part sourced through Multiquip's authorized supply chain, 50262 is manufactured to the same specifications as the original, ensuring a correct drop-in installation with no guesswork on fitment. This key is a critical drivetrain element that locks rotating components — such as shafts and pulleys — in proper alignment, making part accuracy essential for machine performance. Whether you are servicing a RAMMAX walk-behind roller, a reversible plate compactor, or an Essick mixer, part number 50262 is the correct replacement.
Key Features
- Genuine OEM Material Grade — Manufactured to the same hardness and dimensional tolerance as the original, so the key seats fully in its keyway without play or slippage.
- Direct Shaft-to-Hub Engagement — Sized at 1/4 inch x 25 MM to drop directly into the existing keyway slot, restoring the original shaft-to-hub lockup without machining or shimming.
- Broad Fitment Coverage — Compatible with RW1404MR (S/N 326075 and up), RW1504HF (up to S/N 1534188), MVH408DZ, MVH308DZ, and EM900SD equipment.
- Prevents Torque Loss and Component Damage — A worn or missing key allows the hub to spin freely on the shaft, causing immediate loss of drive and accelerating damage to both mating surfaces.
- Authorized OEM Source — Sold by DHS Equipment as an authorized Multiquip parts distributor, so the part number and specification are verified against Multiquip's current parts catalog.
A woodruff or parallel key such as the Multiquip 50262 sits in a machined slot — the keyway — cut into both a shaft and the hub of a mating component like a pulley, sprocket, or impeller. It acts as a mechanical interlock that transfers rotational torque from the shaft to the driven component, preventing the two from rotating independently under load. When a key shears, deforms, or falls out of the keyway, the driven component loses its mechanical connection to the shaft entirely, and continued operation will rapidly widen the keyway slot, making the repair significantly more involved and expensive.
