The Multiquip 26113 Key 3/16 Square x 2-1/4 is a genuine OEM component designed for ST-70 submersible pumps and WSHE-A series vibratory screeds. As a direct OEM part, the part is manufactured to the exact dimensional tolerances required for proper shaft and hub engagement in these machines. Sourced directly through authorized Multiquip distribution, this key is confirmed to fit ST-70 and WSHE-A series equipment without modification. DHS Equipment stocks this part to keep your machines running without extended wait times on critical drive components.
Key Features
- Exact OEM Dimensions — Machined to the precise 3/16 square x 2-1/4 specification required for correct shaft-to-hub torque transfer in Multiquip equipment.
- Direct Drop-In Fit — Designed to seat cleanly into the keyway of ST-70 and WSHE-A series driveshafts, ensuring immediate, secure installation.
- Confirmed Fitment — Compatible with ST-70 submersible pumps and WSHE-A series vibratory screeds across the Multiquip product line.
- Prevents Slippage and Drive Loss — A correctly sized key locks the rotating component to the shaft; a worn or undersized key causes slippage, misalignment, and accelerated wear to both the shaft and hub.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM replacement, backed by Multiquip's parts program and sold by DHS Equipment, an authorized Multiquip distributor.
A shaft key is a small but critical drive component that locks a rotating element — such as an impeller, sprocket, or eccentric shaft — to its driveshaft, preventing independent rotation between the two. It transmits torque by fitting tightly into matching keyways cut into both the shaft and the hub of the driven component. When a key shears, deforms, or wears, the driven component can spin freely on the shaft, resulting in complete loss of power transfer and potential damage to the surrounding keyway surfaces. Replacing a worn or failed key promptly with a correctly dimensioned OEM part protects the shaft and hub from secondary damage that would require far more extensive repairs.
