Key Features

• Genuine OEM Specification: — Manufactured to Multiquip's exact 5/32 x 1/2 dimensional standard, ensuring the pin seats and spreads correctly within the clevis or shaft bore without stress or slop.
• Drop-In Installation: — Matches the original pin bore diameter on all listed models; no drilling, filing, or adaptation needed to seat properly through the retaining hole.
• Broad Cross-Family Fitment: — Confirmed for WM45H, WM45HE, WM45HCE Whiteman mortar mixers, G55H concrete vibrators, and RW3010 and RW1810 RAMMAX walk-behind rollers.
• Locks Critical Fasteners in Place: — A correctly installed cotter pin prevents pins, bolts, and shafts from backing out under vibration, keeping assembled components secured during continuous operation.
• Safety-Critical Retention: — Cotter pins are a primary anti-loosening device on articulating and rotating assemblies; a missing or broken pin can allow linkage separation, making prompt replacement essential for safe machine operation.

A cotter pin is a small split-pin fastener inserted through a drilled hole in a bolt, shaft, or clevis pin to lock it in position and prevent it from walking out under vibration or load. Once inserted, the tails are bent outward to hold the pin securely in place. On equipment like mortar mixers, concrete vibrators, and walk-behind rollers — all of which generate significant continuous vibration — cotter pins serve as a last line of defense against fastener loosening on linkages, handles, and drive assemblies. When a cotter pin shears or goes missing, the component it retains can shift, separate, or fail unexpectedly, so replacing a worn or broken pin promptly is a straightforward but important part of routine equipment maintenance.
