The Multiquip 451406990 Key 15 x 10 x 38 MVC-300G/D is a genuine OEM replacement designed for the MVC300G series plate compactor. Sourced directly through Multiquip's authorized parts network, this keyed component ensures the driven shaft and mating hub engage with the precise fit the machine was engineered around. If you are servicing a MVC300G vibratory plate compactor, 451406990 is the correct OEM-spec part for the job.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact 15 x 10 x 38 mm specification, ensuring full contact across the keyway without play or slippage.
- Direct Keyway Replacement — Drops straight into the existing keyway slot on MVC300G driveline components with no material removal or adjustment needed.
- Confirmed MVC300G Fitment — Engineered specifically for the MVC300G plate compactor, covering both the G (gasoline) and D (diesel) variants referenced in the part description.
- Torque Transfer Integrity — A correctly seated key locks rotational motion between shaft and hub; a worn or sheared key causes slippage, lost compaction force, and accelerated component wear.
- Hardened Drive Component — Keys are subjected to significant shear stress in compactor operation; OEM-spec material grade ensures this part holds up under continuous vibratory loading.
A drive key is a small but critical mechanical component that locks a rotating shaft to a hub, pulley, or gear so that torque is transferred between them without slippage. In a vibratory plate compactor like the MVC300G, the exciter shaft must spin in precise synchronization with the eccentric weight assembly to generate consistent compaction force — the key is what physically enforces that connection. When a key shears or wears down, the shaft spins freely inside the hub, compaction output drops immediately, and the surrounding components begin to wear rapidly from the uncontrolled movement.
