Multiquip 49339 V-Belt B-55 8.0 HP

The Multiquip 49339 V-Belt B-55 8.0 HP is a genuine OEM drive belt designed for MQ Mixer models including MC94SK, MC94PK, MC64SK, MC64PK, MC94P/S, MC64P/S, and the WSC55 Chemical Spray System. Sourced directly from Multiquip, this belt is manufactured to the exact cross-section, length, and tension rating required for correct operation on these machines. A worn or cracked belt causes slippage, reduced drum speed, and eventual drivetrain failure — replacing it with the correct OEM part keeps the machine running at full capacity. DHS Equipment stocks genuine Multiquip parts so you can get back to work without the guesswork.

Key Features

• OEM-Matched Belt Profile — B-55 cross-section and length specification matched exactly to Multiquip drivetrain geometry, ensuring correct tension and power transfer without adjustment.
• Direct Drop-In Replacement — Installs on the existing pulleys of MC94SK, MC94PK, MC64SK, MC64PK, MC94P/S, MC64P/S, and WSC55 models without modification to brackets or hardware.
• Broad MQ Mixer Compatibility — Covers the full range of MC64 and MC94 series concrete mixers in both steel-drum and plastic-drum configurations, plus the WSC55 Chemical Spray System.
• Consistent Power Delivery — A correctly tensioned OEM belt maintains steady drum rotation under load, preventing the slippage and heat buildup that degrade mix quality and wear out pulleys prematurely.
• Genuine Multiquip Part — Manufactured to the same specification as the belt installed at the factory, confirming part number 49339 is the correct service replacement for these models.

A V-belt transmits rotational power from the engine to the drum or pump drive pulley, relying on friction between the belt's angled sidewalls and the pulley groove to transfer torque. On concrete mixers and spray systems, this belt is the critical link between engine output and drum or impeller speed — if it stretches, cracks, or glazes over time, the drum loses speed under load or stops turning entirely. Replacing the belt at the first sign of wear — squealing, visible cracking, or visible slack — prevents secondary damage to bearings and pulleys and restores full mixing or spraying performance.
