Help keep your tool operating reliably with this pin assembly, an important component that attaches to the piston and helps secure the driver in place during operation. Made from durable metal, it supports proper alignment of the driving mechanism for consistent fastening performance. Replacing a worn, damaged, or missing pin assembly can help restore smooth tool function and maintain dependable operation. Because component placement may vary between models, refer to your tool's parts diagram or service manual to confirm the correct installation location before assembly. Installation typically requires removing the existing pin assembly using a hex key and securing the replacement component in place.
Remove the top of the gun, remove the piston/driver. Remove the worn seals. Clean and lube the inside of the gun. Line up the hole in the driver and the hole in the piston, then with a punch drive the larger pin in first, then the small pin inside of the larger one. Install the piston and driver, and the new seals. Then replace the top.
