Multiquip 521139 Pin, Wrist - OEM Replacement Part for Concrete Pumps

The wrist pin is a critical connecting component in concrete pump systems that serves as a pivot point for mechanical linkages in the pumping assembly. This precision-machined pin enables smooth articulation of moving parts while withstanding the high-stress, repetitive motion inherent in concrete pumping operations.

Designed specifically for Multiquip concrete pump models, this wrist pin maintains proper alignment and clearances in critical mechanical connections. Regular inspection of wrist pins should be performed during routine maintenance intervals, particularly when lubricating all links and pivots as specified in the maintenance schedule. Worn or damaged wrist pins can lead to excessive play in mechanical assemblies, reduced pumping efficiency, and potential equipment damage if left unaddressed.

Compatible with the following Multiquip concrete pump models:

• LS300GK (Kubota WG3800-G-E3 Gasoline Engine)
• LS450
