Multiquip 5117 Cotter Pin

The Multiquip 5117 is a genuine OEM Cotter Pin designed for a wide range of Multiquip and Essick equipment, including ride-on power trowels such as the HTX6H, STX6H, STXD6i, STXDF, HTXD6i, and HTXG6DF, mid-sized hydrostatic trowels including the MD80, MD82, and MD105, hybrid power floats in the PRX series, walk-behind trowel families including the B-Series, J-Series, C-4, CA4HC, CA4HM, and CA5BC, Essick and Whiteman mortar and plaster mixers such as the EM12M, EM120SM, WM120SM, and WM120PM, and additional equipment including the V304 roller and MG30 series fireproofing pumps. As a genuine OEM component sourced directly from Multiquip, the 5117 Cotter Pin is manufactured to the exact specification of the original part it replaces. Confirm your model number before ordering to ensure correct fitment across this broad equipment range.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original dimensional and material specification, ensuring the pin seats, locks, and retains with the same holding force as the factory-installed component.
• Direct Installation Fit — Designed to drop into existing pin bores and clevis joints without rework, matching the original pin diameter and leg spread geometry.
• Broad Equipment Compatibility — Fits an extensive range of Multiquip ride-on trowels (HTX6H, STX6H, STXD6i, HTXD6i, HTXG6DF), hydrostatic trowels (MD80, MD82, MD105), PRX hybrid floats, walk-behind trowels, Essick and Whiteman mixers, V304 roller, and MG30 fireproofing pumps.
• Fastener Integrity Under Load — A correctly installed cotter pin prevents shaft, bolt, or clevis pin migration during operation; a missing or fatigued pin can allow critical fasteners to back out and disrupt machine function.
• Safety-Critical Retention — Cotter pins serve as a final mechanical lock on load-bearing and pivot connections; using the correct OEM specification pin maintains the retention force those joints were engineered to depend on.

A cotter pin is a small split-pin fastener inserted through a drilled hole in a shaft or bolt to prevent a nut, clevis pin, or axle from working loose during machine operation. Once inserted, the legs are spread apart to lock the pin in place, creating a positive mechanical stop that cannot vibrate free. When a cotter pin shears, fatigues, or goes missing entirely, the fastener it secures is free to back out — which can lead to lost components, misaligned linkages, or failure of the mechanism the pin was protecting. Because they are subject to shear forces and repeated vibration cycles, replacing worn or deformed cotter pins with a correctly sized OEM part is a straightforward but important step in any scheduled inspection or reassembly procedure.
