The Multiquip 20363 Rectangular Key.188 X.25 X 2.500 is a genuine OEM component designed for Whiteman and International ride-on power trowel models including the HHXG5, HHXD5, HHN31V, HHNG5, HHXDF4-DF5, EHHNK5, HHXD5-ES, and HHN34TVD. Sourced directly from Multiquip, this key meets the exact tolerances required to maintain correct shaft-to-hub engagement in the trowel drivetrain. Using the correct OEM part ensures the key seats properly in its keyway, delivering consistent torque transfer without slippage or premature wear. DHS Equipment supplies this part with verified part number accuracy so you can order with confidence.
Key Features
- Exact OEM Tolerancing — Manufactured to Multiquip's precise dimensional spec of .188 x .25 x 2.500, ensuring full keyway contact and zero play between shaft and hub.
- Direct Drop-In Replacement — Seats directly into the existing keyway slot with no filing, shimming, or machining required.
- Broad Whiteman Trowel Compatibility — Confirmed fit across HHN and HHXG/HHXD series Whiteman ride-on power trowels, including the HHXDF4-DF5 dual-blade models and EHHNK5 international units.
- Positive Torque Transfer — A correctly fitted rectangular key locks rotating components in alignment, preventing blade-speed inconsistency and protecting adjacent drivetrain components from impact damage.
- Genuine Multiquip OEM Part — Supplied under Multiquip part number 20363, this is not a substitute or approximation — it is the same component used in original assembly.
A rectangular key is a small but critical drivetrain component that sits in a machined slot — called a keyway — cut into both a shaft and its mating hub or gear. Its job is to lock the two rotating parts together so torque is transmitted cleanly from one to the other rather than allowing them to spin independently. On a ride-on power trowel, this type of key is commonly used in the blade-drive and transmission assemblies where reliable, slip-free power delivery is essential to consistent finishing performance. When a key wears, shears, or goes missing, the result is lost drive, erratic blade speed, or accelerated damage to the shaft and hub — making timely replacement with the correct-sized key essential.
