The Multiquip 502064 Drive Pinion Shaft is a genuine OEM component designed for Multiquip, Essick, Whiteman, and STOW concrete mixer models including the EC-92S, EC-92P, MC-92S, MC-92P, WC-92S, WC-92P, and CMS-9. Sourced directly from Multiquip, this shaft delivers an exact-fit replacement that restores proper drum rotation without guesswork or modification. As a genuine OEM part, it is manufactured to the same specifications as the original component installed at the factory, ensuring consistent performance across the full range of compatible 9-cubic-foot drum mixers.
Key Features
- Genuine OEM Construction — Machined to Multiquip's original dimensional tolerances, ensuring correct gear mesh and load transfer within the mixer drive assembly.
- Direct-Fit Replacement — Engineered to drop into the existing drive housing on compatible mixers, aligning with the ring gear and drive train as originally assembled.
- Broad Mixer Compatibility — Fits the EC-92S, EC-92P, MC-92S, MC-92P, WC-92S, WC-92P, and CMS-9 concrete mixer models, covering Essick, Whiteman, STOW, and Multiquip-branded units in the 9 cu ft class.
- Sustained Drum Drive Integrity — A correctly functioning pinion shaft transmits power smoothly from the motor to the drum; a worn or damaged shaft causes erratic drum rotation, excessive noise, or complete drive failure on the pour site.
- Verified Part Number — Order with confidence using Multiquip part number 502064 to confirm you are receiving the correct shaft for your mixer model.
The drive pinion shaft is a core component of the concrete mixer's gear-drive system, transferring rotational force from the motor through the ring gear to keep the drum turning continuously during mixing. It works under constant load and is subject to wear from grit, concrete residue, and heavy-duty cycling. When the pinion shaft wears or fails, the drum may lose power, rotate unevenly, or stop entirely — interrupting the mix cycle and potentially ruining a batch. Replacing a worn shaft promptly with the correct OEM part restores full drive function and protects the surrounding gear components from secondary damage.
