The Multiquip EM924045 Cotter Pin 5/32X1-1/2 ST30 60 80 is a genuine OEM fastener designed for ST30 series concrete pumps. This small but critical hardware component is manufactured to exact Multiquip specifications, ensuring a proper fit and secure hold in the assembly it serves. Sourced directly through authorized Multiquip channels, EM924045 is the correct service replacement for ST30 swing tube concrete pump applications.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Multiquip's exact material and dimensional spec for the cotter pin application, ensuring the pin seats and spreads correctly without risk of premature shear or pull-through.
- Direct-Fit Hardware — Sized at 5/32" diameter by 1-1/2" length to drop straight into the original pin bore on ST30 series concrete pump assemblies with no trimming or modification.
- Confirmed Compatibility — Verified fitment for the ST30 concrete pump series, covering ST30, ST60, and ST80 swing tube pump models.
- Secures Critical Moving Linkages — Retains pins, bolts, and fastener assemblies in high-cycle pump mechanisms where vibration and reciprocating motion would otherwise cause hardware to back out or loosen.
- Safety-Critical Retention Function — Cotter pins in concrete pump linkages prevent unintended disassembly of load-bearing connections during operation; using the correct OEM-spec pin is essential to maintaining structural integrity of the pump assembly.
A cotter pin is a split fastener inserted through a drilled hole in a bolt, shaft, or clevis pin to lock it in place and prevent it from backing out under vibration or load. In concrete pump applications like the ST30 series, cotter pins secure critical linkage and valve train connections that cycle continuously under pressure — a missing or failed cotter pin can allow a retaining pin to walk out of position, causing linkage slop, component damage, or an unsafe condition. Replacing a worn, bent, or missing cotter pin with the correct OEM part restores the mechanical lock and keeps the assembly operating as designed.
