Multiquip EM23305 Bearing End Weldment - OEM Replacement Part for Concrete Pumps

The bearing end weldment provides critical structural support and alignment for the concrete pumping cylinder assembly in Multiquip trailer-mounted concrete pumps. This precision-welded component houses bearing surfaces that ensure smooth piston operation during high-pressure concrete delivery cycles, directly affecting pump performance and longevity.

During pump maintenance procedures outlined in Multiquip service manuals, technicians remove hydraulic hoses, discharge nipples, tie rod nuts, and eyebolt nuts to access internal wear components. The bearing end weldment must maintain precise alignment with piston assemblies and face plates during reassembly to prevent premature wear and maintain proper concrete flow. When installing related components, all bolts should be equally snugged and tightened to specified torque values, with 3/8" bolts torqued to 55 ft-lbs and coated with silicon sealant on bolt head backs.

This component is essential for operators performing hopper removal procedures or addressing wear plate replacements on trailer-mounted structural concrete pumps.
