Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Husqvarna's exact 1/8 x 1-1/4 specification, ensuring the pin seats and locks correctly in its bore without play or misalignment.
- Direct-Install Replacement — Drops straight into the factory-designed retention point, requiring no modification to the surrounding hardware or assembly.
- CT48I and CT36I Compatibility — Confirmed fitment for both the CT48I and CT36I ride-on power trowels, covering common configurations in the Husqvarna trowel lineup.
- Secure Fastener Retention — A correctly seated cotter pin holds critical fasteners and linkage pins in position during operation; a worn or missing pin can allow hardware to back out under vibration, compromising machine control.
- Operational Safety Relevance — Cotter pins serve as a final mechanical lock in linkage and pivot assemblies; using the correct OEM-spec pin ensures the locking function performs as designed under troweling loads and vibration.
A cotter pin is a split fastener inserted through a drilled hole in a bolt, shaft, or clevis pin to prevent it from working free during machine operation. On ride-on power trowels like the CT48I and CT36I, cotter pins secure linkage connections, pivot points, and other hardware that are subjected to continuous vibration and rotational forces. When a cotter pin fails, bends, or goes missing, the fastener it retains can shift or eject entirely, creating misalignment in the assembly and a potential safety hazard. Replacing a damaged or missing cotter pin with the correct OEM part restores the mechanical lock and keeps the assembly operating as designed.
