The Multiquip 500194 Square Key SC-90 is a genuine OEM component designed for V305EH and V305EK walk-behind vibratory rollers. As a direct factory replacement, part 500194 meets the same specifications as the original key installed at the time of manufacture, ensuring correct shaft-to-hub engagement without rework or modification. This key is confirmed to fit both the electric-start Honda (V305EH) and electric-start Kohler (V305EK) variants of the V305 roller series. Sourcing the correct OEM key matters — an improperly fitted or worn key can lead to slipping, drive loss, or component damage that takes equipment out of service.

Key Features

  • Genuine OEM Specification: — Manufactured to the exact dimensional tolerances of the original SC-90 key, ensuring proper load transfer between mating shaft and hub components.
  • Direct Drop-In Replacement: — Seats into the existing keyway without machining or fitting; designed to swap out as part of a standard drivetrain service.
  • Confirmed Fitment: — Compatible with Multiquip V305EH and V305EK walk-behind vibratory rollers; verify your model before ordering.
  • Drive Integrity: — A correctly installed square key locks the rotating assembly to the shaft, maintaining full torque transmission to the drum and preventing slippage under load.
  • Wear Part Awareness: — Keys are subject to shear and wear over time; replacing a worn or damaged key promptly prevents escalating damage to the shaft and hub.

A square key is a small but critical drivetrain component that locks a rotating part — such as a pulley, sprocket, or drum hub — securely to its shaft. It fits into a machined slot called a keyway on both the shaft and the mating component, transmitting torque and preventing relative rotation between the two. When a key wears, shears, or goes missing, drive power cannot be transferred effectively, causing slippage or complete loss of function in the affected assembly. Replacing the key with the correct OEM part restores full mechanical coupling and protects the surrounding components from accelerated wear.
