The Multiquip 490338Y Ring Gear is a genuine OEM component designed for the CMS-9 concrete mixer. Sourced directly from Multiquip, this ring gear meets the original engineering specifications for the CMS-9, ensuring a direct fit without modification. DHS Equipment stocks this OEM part to help keep your mixer turning and your crew productive on the pour.
Key Features
- Genuine OEM Tooth Profile and Material Grade — Manufactured to the same hardness and gear geometry as the original, ensuring correct mesh engagement with the drive system.
- Direct-Fit Replacement for CMS-9 — Engineered to drop into the CMS-9 drum drive assembly using the original mounting points and hardware.
- CMS-9 Mixer Compatibility — Verified fitment for the Multiquip CMS-9 concrete mixer series.
- Restores Full Drum Rotation Speed and Torque — A worn or cracked ring gear causes the drum to slip, stall, or rotate erratically; replacing it restores consistent mixing action and batch quality.
- Authorized Multiquip OEM Part — Supplied through an authorized Multiquip distributor, this part carries the same part number (490338Y) referenced in Multiquip service documentation.
The ring gear is a critical component in a concrete mixer's drum drive system. It transfers rotational force from the drive pinion to the mixing drum, keeping the barrel turning at the correct speed to blend aggregate, cement, and water into uniform concrete. When the ring gear wears, chips, or cracks, the drum loses torque, rotates unevenly, or stops turning altogether — leading to poor mix consistency and potential damage to surrounding drive components. Replacing the ring gear promptly with the correct OEM part restores proper drum function and protects the rest of the drive train.
