Multiquip 13331357000 Special Woodruff Key 25X18

The Multiquip 13331357000 is a genuine OEM Special Woodruff Key 25X18 designed for a wide range of Multiquip equipment including MVC, MVH, MTX, and WM series machines. As a factory-original component, this key is manufactured to the exact dimensional tolerances required for proper shaft and hub engagement across all listed models. Compatible equipment includes plate compactors such as the MVC82VHW, MVC82VH, MVB85H, MVH128GH, MVH158GH, MVC88VTHW, MVC88VTH, MVC64VHW, MVC64VH, and MVC90H; rammers including the MTX80HDR and MTX70HDR; walk-behind trowels CA4HM and CA-4-4H; mixers MC44S, MC64P/S, and WM70S/P; generators GAC2.5HR, GA2.5HR, and GAC2.2HZ; masonry saws MP1455HP, MP120E, MP115E, and MP1H; flat saw SP1G; centrifugal pump QP205SH; and concrete vibrator G55H. Sourcing the correct OEM key ensures the shaft connection seats and locks as designed, preventing slippage or drive failure on the job.

Key Features

• Exact OEM Dimensional Tolerance — Manufactured to the precise 25x18 Woodruff key profile required for correct shaft-to-hub engagement across all compatible Multiquip models.
• Genuine Multiquip Part — Supplied as a factory-original OEM component under part number 13331357000, ensuring material grade and geometry match the original specification.
• Broad Cross-Family Fitment — A single verified part covering plate compactors (MVC, MVH, MVB series), rammers (MTX series), walk-behind trowels, mixers, saws, pumps, generators, and vibrators.
• Secure Power Transmission — A correctly sized Woodruff key locks the shaft and driven component together, maintaining full torque transfer and preventing rotational slippage under load.
• Direct Drop-In Replacement — Matches the original keyway slot dimensions so the key seats flush without filing, shimming, or machining during installation.

A Woodruff key is a small, semi-circular metal insert that fits into a machined slot — called a keyway — shared between a rotating shaft and a hub or pulley. Its purpose is to lock those two components together rotationally, so that torque from the engine or motor transfers fully to the driven part without slipping. Because the key sits in a precisely cut slot, even a slight variation in size can result in a loose fit, leading to fretting, key shear, or complete drive failure. When a Woodruff key wears, breaks, or goes missing, the shaft and hub spin independently, causing an immediate loss of drive to whatever component that shaft powers. Using the correct OEM-dimensioned key — in this case the Multiquip 13331357000 at 25x18 — ensures the keyway is filled properly and the connection remains solid throughout the service life of the surrounding components.
