The Multiquip 26113-001 is a genuine OEM Key, 3/16 Square x 2-1/4 designed for ST-70 submersible pumps and WSHE-A series vibratory screeds. As a direct Multiquip OEM part, it is manufactured to the same tolerances as the original component, ensuring a precise match to the keyway dimensions on the shaft and hub. Verified fitment for ST-70 and WSHE-A series equipment makes this the straightforward choice when servicing either machine family.
Key Features
- OEM-Matched Keyway Dimensions — Manufactured to the exact 3/16 square cross-section and 2-1/4 length spec, ensuring full contact across the keyway for proper torque transfer between shaft and hub.
- Drop-In Shaft Replacement — Seats directly into the existing keyway slot with no recutting or shimming, restoring the drive connection exactly as it left the factory.
- Broad Fitment Across Two Machine Families — Confirmed for ST-70 submersible pumps and WSHE-A series vibratory screeds, covering multiple applications with a single part number.
- Restores Full Power Transmission — A worn or sheared key allows the shaft and driven component to slip independently, resulting in loss of pump output or screed vibration; replacing it restores full mechanical drive.
- Genuine Multiquip OEM Quality — Sourced directly from Multiquip, this key meets the material hardness and dimensional standards required for consistent performance under the torsional loads of both pump and screed operation.
A square shaft key is a small but load-critical component that locks a rotating shaft to a hub, impeller, or drive element, transmitting torque between the two without slippage. When a key shears or wears, the driven component — whether a pump impeller or screed eccentric shaft — can spin freely on the shaft, causing a sudden loss of function. Replacing the key promptly with a correctly sized OEM part restores the mechanical connection and prevents secondary wear damage to the keyway itself.
