Additional information
This spring pin, part number 715-0143, presses into aligned holes to secure shafts, gears, or linkage components while allowing slight compression to absorb vibration. Proper installation helps keep components firmly in place during snowblower operation.
If a shaft slips, linkage separates, or you notice unexpected movement in the assembly, the spring pin may be sheared, worn, or missing. Elongated holes or visible pin damage can also indicate a problem.
Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Align the holes carefully, then drive the spring pin straight in until it seats fully and holds the components securely.
