The Multiquip 451407510 is a genuine OEM Key 5.5 x 6.3 x 43 designed for the MVC-40 single-directional plate compactor. As a factory-sourced component, it meets the exact dimensional and material specifications required for proper drivetrain engagement on MVC-40 equipment. Sourcing the correct key ensures your compactor maintains full power transfer without slipping or accelerated wear at the shaft interface. DHS Equipment stocks this part so you can get your MVC-40 back to work without delay.
Key Features
- Genuine OEM Dimensional Accuracy — Machined to the exact 5.5 x 6.3 x 43 specification, ensuring full contact and engagement at the keyway without gaps or play.
- Direct Shaft-to-Hub Fit — Engineered to drop directly into the MVC-40 keyway seat, aligning shaft and hub for immediate, secure torque transfer.
- MVC-40 Specific Fitment — Confirmed for MVC-40 series plate compactors; use part number 451407510 to verify compatibility before ordering.
- Prevents Power Loss at the Drive Interface — A correctly fitted drive key locks the rotating assembly in place; a worn or missing key causes slippage, vibration irregularity, and potential damage to the shaft and hub bore.
- Hardened Material Grade — Manufactured from appropriately hardened steel to withstand the continuous rotational stress and vibration loads inherent to vibratory plate compactor operation.
A drive key is a small but critical component that locks a rotating shaft to a hub, pulley, or sprocket, ensuring both parts turn together as a single unit. In a plate compactor like the MVC-40, the key transmits engine torque through the drivetrain to drive the eccentric weight that produces compaction force. When a key shears, deforms, or goes missing, the shaft spins independently of the driven component, resulting in a loss of vibration output and potential secondary damage to the keyway surfaces on both the shaft and the hub.
