The Multiquip EM20363 is a genuine OEM Steel Key.188 X.250 X 2.5 designed for HHN and HHX series ride-on power trowels, including models EHHNK5, HHN31VTCSL5, HHN34TVD, HHNG4, HHNG5, HHXD5. As a direct Multiquip OEM component, EM20363 is manufactured to the exact dimensions required for correct shaft-to-hub engagement on these machines. Sourced directly through authorized distribution, this key ensures the rotating assembly seats and locks as originally intended. Verify your model code before ordering to confirm fitment.
Key Features
- Exact OEM Dimensioning — Manufactured to precise .188 x .250 x 2.5 inch specifications, ensuring correct load transfer between shaft and hub without play or misalignment.
- Drop-In Shaft Compatibility — Sized to fit the keyed shaft and hub bores on HHN and HHX series ride-on trowels without machining or modification to mating components.
- Broad HHN and HHX Series Coverage — Confirmed fitment across EHHNK5, HHN31VTCSL5, HHN34TVD, HHNG4, HHNG5, HHXD5, HHXG5, HHN31V, HHXDF4, and HHXDF5 models.
- Torque Transmission Integrity — A correctly fitted steel key locks the rotating assembly so blade speed and pitch control respond accurately — a worn or undersized key causes slippage, erratic blade performance, and accelerated hub wear.
- Genuine Multiquip OEM Part — Supplied as an original equipment component under part number EM20363, meeting the same material and hardness standards as the key installed at the factory.
A steel key is a small rectangular drive component seated in matching keyways cut into both a shaft and its mating hub or gear. Its role is to transmit rotational torque between the two parts, preventing the hub from spinning freely on the shaft under load. On a ride-on power trowel, the key must maintain a firm, precise fit at all times — any looseness allows the hub to rock or slip, which degrades blade control, introduces vibration into the drivetrain, and rapidly damages the keyway surfaces on both the shaft and the hub. Replacing a worn or sheared key promptly with the correct OEM-dimensioned part protects the surrounding components and restores full power transfer to the trowel blades.
