Multiquip EM493399 V-Belt B-55 8.0 HP

The Multiquip EM493399 V-Belt B-55 8.0 HP is a genuine OEM drive belt designed for MQ concrete mixer models including the MC94SK, MC94PK, MC64SK, MC64PK, MC94P, MC94S, MC64P, and MC64S series. Sourced directly from Multiquip, this belt is manufactured to the exact profile, length, and tension specifications required by these mixers. It installs as a direct drop-in replacement on compatible 8.0 HP mixer configurations, restoring proper power transfer from the engine to the drum without adjustment or modification. Keeping a fresh EM493399 on hand means your mixer stays productive through demanding pours and continuous mixing cycles.

Key Features

• Correct B-55 Profile and Length — Matched to the exact cross-section and outside circumference required by 8.0 HP MQ mixer drive systems, ensuring proper belt seating and tension from the first start.
• Genuine OEM Construction — Made to Multiquip's specified rubber compound and cord reinforcement grade, delivering the flex resistance and load capacity this drive system demands under continuous mixing use.
• Broad MQ Mixer Compatibility — Confirmed fitment across MC94SK, MC94PK, MC64SK, MC64PK, MC94P, MC94S, MC64P, and MC64S concrete mixer models.
• Sustained Drum Drive Performance — A correctly tensioned belt transfers engine power to the drum efficiently; a worn or slipping belt causes uneven drum rotation, reduced mixing quality, and accelerated pulley wear.
• Direct OEM Part Number Reference — Ordering by part number EM493399 eliminates guesswork and ensures you receive the belt Multiquip specifies for these machines.

The V-belt on a concrete mixer is the critical link between the engine output shaft and the drum drive pulley. It transfers rotational power to keep the drum turning at the correct speed and torque needed to mix concrete thoroughly and consistently. When a V-belt stretches, frays, or cracks, the drum may slip, slow, or stop turning altogether — interrupting the mix cycle and potentially damaging the drum drive components. Regular inspection and timely replacement of the belt keeps the mixer operating at full capacity and protects the pulleys and bearings from the stress of a loose or failing drive.
