Key Features
- Exact OEM Dimensions: — Manufactured to the precise 1/4 x 35 MM specification required for proper seating and torque transfer in the mixer shaft assembly.
- Direct Drivetrain Replacement: — Drops into the existing keyway without machining or modification, restoring the mechanical connection between shaft and sprocket or gear.
- Broad Mixer Compatibility: — Confirmed fit for MC94P/S, MC44S, MC94SK, MC94PK, and MC12PH Multiquip concrete mixer models.
- Prevents Power Loss: — A worn or missing square key causes the shaft to slip under load, resulting in lost drum rotation and uneven mixing; this replacement restores full power transmission.
- Genuine OEM Part: — Supplied as an authentic Multiquip component, ensuring the correct hardness grade and dimensional accuracy for the intended application.
A square key is a small but critical drivetrain component that locks a rotating shaft to a gear, pulley, or sprocket, ensuring power transfers cleanly from the engine to the drum. Seated in a machined keyway on both the shaft and the mating component, it prevents slippage under the torsional loads generated during mixing. When a square key shears, wears down, or goes missing, the drum loses drive entirely or rotates inconsistently — making a replacement essential before the mixer can return to service.
