Key Features
- Genuine OEM Material Grade — Manufactured to the same material hardness and dimensional tolerance as the original, ensuring the pin seats and spreads correctly in the clevis or axle bore without premature failure.
- Drop-In Installation — Matches the original 1/8 x 1-1/2 in. specification exactly, so it slides into the existing hole and bends without any rework or resizing.
- Broad Equipment Compatibility — Confirmed fit across LS-series concrete pumps, LS40/50/60TD series, V305EK and V305EH walk-behind rollers, AR14H ride-on roller, and WTB-16 power buggies.
- Positive Retention Under Load — A correctly installed cotter pin locks fasteners, pins, and clevis connections in place under vibration and dynamic load, preventing unintended loosening or component separation during operation.
- Safety-Critical Fastener — Cotter pins secure load-bearing and linkage connections; using the correct OEM-specified size ensures the locking mechanism performs as designed and meets original assembly requirements.
A cotter pin is a split fastener inserted through a drilled hole in a bolt, axle pin, or clevis shaft and then bent outward to lock the assembly together. Its job is to prevent a nut, pin, or linkage component from backing out or shifting under vibration and operational stress. When a cotter pin shears, corrodes, or goes missing, the fastener it secures can work loose — leading to lost components, accelerated wear on surrounding parts, or loss of control over a linkage or drive connection. Replacing a worn or missing cotter pin promptly with the correct OEM part restores the integrity of the connection and keeps the assembly operating as intended.
