The Multiquip 509074 is a genuine OEM Cotter Pin 3/32" designed for R2000H, AR13D, LS300P, and WTB-16PD series equipment. As a direct Multiquip OEM part, 509074 is manufactured to the exact dimensions and material grade required for proper function and secure retention in your machine. This cotter pin fits across multiple Multiquip equipment families including rollers, concrete pumps, and power buggies, making it a practical stock item for crews running mixed fleets. Sourcing the correct OEM part ensures the pin seats and spreads exactly as intended, maintaining secure fastener retention without adjustment or rework.
Key Features
- OEM-Grade Material: Manufactured to the precise wire diameter and temper required for reliable retention under vibration and load — not an approximation of the spec.
- Exact 3/32" Diameter: Matches the original bore clearance on R2000H, AR13D, LS300P, and WTB-16PD assemblies, so the pin installs and spreads correctly without over-stressing the clevis or bracket.
- Broad Multiquip Fitment: A single part number that crosses rollers, concrete pumps, and power buggies — confirmed for R2000H, AR13D, LS300P, and WTB-16PD.
- Secure Fastener Retention: A correctly sized and properly installed cotter pin locks pins, bolts, and shaft-end hardware in place, preventing component migration during operation.
- Safety-Critical Fastener: Cotter pins are a primary anti-loosening device on pivot points and linkage hardware — using an undersized or incorrect-grade pin risks unintended disassembly of retained components during use.
A cotter pin is a split-leg fastener inserted through a drilled hole in a shaft or bolt to prevent a nut, clevis pin, or axle component from backing out during operation. Once inserted, the legs are bent apart to lock the pin in place mechanically. On equipment like rollers, concrete pumps, and power buggies, cotter pins are commonly used at pivot points, linkage connections, and wheel end hardware where vibration and dynamic loads would otherwise allow fasteners to work loose. A missing or failed cotter pin allows retained components to migrate or disengage, which can lead to loss of control over critical mechanical linkages.
