The Multiquip 10057-016 is a genuine OEM Square Key 3/16 x 1-1/2 designed for Whiteman mortar and plaster mixer models WM45H, WM45HE, and WM45HCE.

DHS Equipment stocks this component so you can get your Whiteman mixer back in service without the guesswork of sourcing a substitute.
Key Features
- Exact OEM Dimensions — Machined to the precise 3/16 x 1-1/2 specification required for correct seating and full torque engagement on the shaft.
- Genuine Multiquip Part — Sourced directly from Multiquip, ensuring the material grade and dimensional tolerances match the original hardware exactly.
- Direct Drop-In Replacement — Slots into the keyway without modification, restoring the shaft-to-hub connection as originally assembled.
- Confirmed Fitment — Verified for Whiteman mixer models WM45H, WM45HE, and WM45HCE; use part number 10057-016 to confirm compatibility before ordering.
- Protects Drivetrain Components — A correctly sized and properly seated key prevents shaft and hub damage caused by slippage or misalignment under load.
A square key is a small but critical drivetrain component that locks a rotating shaft to a hub, gear, or sprocket, transferring rotational force without allowing the two parts to slip relative to each other. On a Whiteman mortar mixer, the key ensures the drum or drive assembly rotates in unison with the drive shaft under the full working load of the mix. When a key shears, wears down, or goes missing, the shaft spins freely inside the hub, resulting in loss of drum drive and potential damage to the keyway itself — turning a simple replacement into a more costly repair if left unaddressed.
