The Multiquip 951402340 Key 7x7x40 MR-8D is a genuine OEM replacement designed for the MR-8D. Sourced directly from Multiquip, this part meets the original equipment specification and installs without modification. If you're servicing MR-8D equipment, using the correct keyed component is essential for maintaining proper shaft and hub engagement. DHS Equipment stocks this part so you can get your machine back in service quickly.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original dimensional tolerances, ensuring the key seats correctly in both the shaft and hub keyways without play or slop.
- Exact 7x7x40 Profile — The precise 7x7x40 mm parallel key geometry matches the OEM slot dimensions on MR-8D equipment for a flush, secure fit.
- Direct MR-8D Compatibility — Engineered specifically for the MR-8D, eliminating guesswork when sourcing a replacement during a service interval or breakdown repair.
- Torque Transfer Integrity — A correctly sized and seated key ensures full, consistent torque transfer between rotating components — a worn or undersized key can cause slippage, vibration, and accelerated wear on mating surfaces.
- Durable Material Grade — Built from hardened steel stock appropriate for power transmission applications, providing the shear strength needed under operational load cycles.
A woodruff or parallel key is a small but critical power transmission component that locks a rotating shaft to a hub, pulley, gear, or sprocket. It sits in matched keyways cut into both parts, preventing relative rotation under load and ensuring the driven component turns in unison with the shaft. When a key shears, wears down, or goes missing, the shaft spins independently of the mounted component — resulting in lost drive, erratic machine behavior, or damage to the keyway itself. Replacing a worn key with the correct OEM part, such as the Multiquip 951402340, restores full mechanical engagement and protects the surrounding components from further wear.
