The Husqvarna 539300283 Hair Cotter Pin is a genuine OEM component designed for the RS8500D floor saw. As a direct factory replacement, this pin is manufactured to Husqvarna's exact specifications, ensuring a correct, secure fit within the assembly it fastens. DHS Equipment supplies this part to help keep your RS8500D floor saw operating as intended.
Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact material and dimensional specifications, ensuring the pin seats and locks with the correct retention force for its application.
- Direct Assembly Fit — engineered as a drop-in replacement that installs exactly as the original, with no reworking of the surrounding components required.
- RS8500D Floor Saw Compatibility — confirmed fitment for the RS8500D floor saw; cross-reference 539300283 against your parts diagram before ordering to verify correct application.
- Secure Component Retention — a correctly seated hair cotter pin prevents unintended movement or disengagement of fastened components, keeping the assembly intact during operation.
- Restored Mechanical Integrity — replacing a bent, worn, or missing cotter pin restores the full structural security of the fastened joint, eliminating play or separation at that connection point.
A hair cotter pin is a small but essential fastening component used to lock a bolt, shaft, or pin in place within an assembly. Once inserted and bent open, it prevents the retained component from backing out or shifting during machine operation. When a cotter pin becomes bent beyond reuse, corroded, or goes missing, the joint it secures loses its mechanical lock — potentially allowing connected parts to work loose. Replacing it promptly with the correct OEM part restores the intended retention and keeps the assembly secure.
