Multiquip 0683 Cotter Pin 3/32 In. Dia x 3/4 In. L

The Multiquip 0683 Cotter Pin 3/32 In. Dia x 3/4 In. L is a genuine OEM fastener designed for a wide range of Multiquip and Whiteman equipment, including HTX6H, STX6H, HTN28K, HTN27K, J36E2, HDA-Series, JWN24HTCSL, MP-Series masonry saws, GAW180HE, GA2.5HR, and GAC2.5HR models. As a direct OEM replacement, this cotter pin is built to the same dimensional and material standards as the original component that shipped with your machine. Sourced through authorized Multiquip distribution channels, part number 0683 ensures you receive a part that fits and functions exactly as intended across all compatible platforms.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact dimensional tolerances, ensuring the pin seats correctly and holds secure under operational load and vibration.
• Broad Equipment Compatibility — Fits HTX6H, STX6H, HTN28K, HTN27K, J36E2, HDA-Series, JWN24HTCSL, MP-Series masonry saws, GAW180HE welders, and GA2.5HR/GAC2.5HR generators.
• Drop-In Replacement — Matches the original 3/32 in. diameter and 3/4 in. length specification, so installation is straightforward with no modification to existing hardware or mounting points.
• Operational Integrity — A correctly installed cotter pin prevents critical fasteners from backing out during operation; a missing or worn pin can lead to component separation and unexpected machine failure.
• Safety-Critical Fastener — On trowels, saws, and generators, cotter pins secure axles, linkage pins, and control hardware where unintended movement creates a direct safety hazard to the operator.

A cotter pin is a small split fastener inserted through a drilled hole in a bolt, shaft, or clevis pin to prevent it from working loose during equipment operation. Once inserted and the tails are bent apart, the pin creates a mechanical lock that resists vibration and axial movement. On power trowels, it commonly secures pitch control linkages and blade spider assemblies; on masonry saws and generators, it locks pins in clevis and cable anchor points. When a cotter pin shears, corrodes, or goes missing, the retained fastener is free to migrate out of position, which can result in loss of blade pitch control, a loose drive component, or an unsecured linkage — making timely replacement with the correct OEM part essential for safe, predictable machine operation.
