The Multiquip 4024 is a genuine OEM Key 1/4 Sq X 2-1/4 designed for the MVC90H plate compactor. Sourced directly from Multiquip, this keyed drive component ensures correct shaft-to-hub engagement on the MVC90H, maintaining the precise mechanical connection the machine depends on during operation. Choosing the correct OEM key means no guesswork on sizing or fit — part number 4024 is the exact spec called out for this application.
Key Features
- Exact OEM Dimensions — Genuine Multiquip 1/4 square cross-section and 2-1/4 inch length match the original machined keyway tolerances on the MVC90H shaft assembly.
- Direct Shaft Drop-In — Seats into the existing keyway slot without modification, restoring the positive drive connection between rotating components immediately.
- Confirmed MVC90H Fitment — Part number 4024 is verified for the Multiquip MVC90H single-directional plate compactor.
- Torque Transfer Integrity — A correctly sized drive key locks the hub to the shaft, preventing slippage under the high vibratory loads a plate compactor generates during compaction passes.
- Genuine Multiquip OEM Part — Manufactured to the same material hardness and dimensional spec as the original, so the key shears predictably under overload rather than damaging the shaft or hub.
A drive key is a small rectangular or square metal insert that sits in a machined slot — called a keyway — cut into both a shaft and a mating hub or pulley. Its job is to lock those two components together so they rotate as a single unit, transferring torque without slip. On a plate compactor like the MVC90H, the key ensures the eccentric weight assembly or drive component stays positively coupled to the engine output shaft under continuous vibration. When a key wears, shears, or goes missing, the driven component spins freely on the shaft, causing an immediate loss of compaction force and potential damage to the surrounding keyway surfaces if the machine continues to run.
