The Multiquip EM20328 Bearing Kit Connecting/Drive Rods is a genuine OEM component designed for C30HD series Mayco concrete pumps, including the C30HD, C30HDGA, C30HDG, C30HDN, C30HDNI, C30HDNI Precision, C30HDNI Zenith, and C30HDZ. As a direct OEM replacement, EM20328 is built to the same specifications as the original factory part, ensuring correct fit and function across the full C30HD family. Sourced directly through Multiquip's authorized parts network, this kit gives you the confidence that comes with using the right part for the job.
Key Features
- OEM-Grade Bearing Precision — Each bearing in this kit is manufactured to the original tolerances required for connecting and drive rod applications in cycloidal concrete pump drivetrains, where tight clearances directly affect pump output and longevity.
- Complete Kit Format — Includes all necessary bearings for the connecting and drive rod assembly, so you can complete the service in a single repair without sourcing individual components separately.
- Broad C30HD Series Coverage — Confirmed fitment across C30HD, C30HDGA, C30HDG, C30HDN, C30HDNI, C30HDNI Precision, C30HDNI Zenith, and C30HDZ models.
- Restores Smooth Pump Stroke Action — Worn connecting and drive rod bearings cause excessive play, vibration, and uneven concrete delivery. Replacing them with EM20328 restores consistent stroke motion and pumping output.
- Genuine Multiquip OEM Part — Backed by Multiquip's parts program, EM20328 carries the same part number referenced in the factory service documentation for the C30HD series.
The connecting and drive rod bearings are a critical part of the cycloidal drive system that powers the pumping action in C30HD series concrete pumps. These bearings allow the connecting and drive rods to rotate and reciprocate smoothly under the significant load generated during concrete pumping operations. When these bearings wear or fail, the result is increased mechanical play, abnormal vibration, accelerated wear on surrounding components, and ultimately a loss of consistent concrete output — which can bring a pour to a halt. Replacing them as part of a scheduled service or at the first sign of roughness keeps the drivetrain operating as intended.
