Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact material and dimensional spec of the original AM-66 rivet used in Multiquip Mayco concrete pump assemblies, ensuring proper retention force and corrosion resistance in high-demand environments.
- Drop-In Installation — Designed to seat into the same hole pattern and mating surfaces as the factory rivet, requiring no rework or re-drilling of the surrounding assembly.
- Broad Concrete Pump Compatibility — Fits a wide range of Mayco hydraulic-driven concrete pump models including LS300, LS400, LS500, LS600, LS40D, LS40TD, LS50TD, LS600P, LS300P, and C30HDGA.
- Structural Integrity Where It Counts — Rivets in concrete pump assemblies secure panels, guards, and structural brackets that protect internal hydraulic and mechanical components from concrete slurry, impact, and vibration stress.
- Verified by Part Number — Order with confidence using Multiquip part number EM491754 — the correct OEM reference for the AM-66 rivet across all compatible Mayco pump models listed above.
A rivet is a permanent mechanical fastener used to join two or more components by deforming its tail end to clamp them together. In Mayco concrete pumps, rivets like the AM-66 secure enclosure panels, mounting brackets, and protective guards that keep the hydraulic drive and pumping components shielded from the harsh conditions of concrete placement work. A missing, sheared, or corroded rivet can allow panels to shift or vibrate loose, exposing sensitive internal parts to concrete slurry, debris, and mechanical damage — making timely replacement an important part of pump upkeep.
