I have an older FR350 nailer. The coil return spring broke. I have the replacement and want to fix it. Do I have to take the whole nail guid assembly off to replace this part!
The best way to replace the spring is to remove the rails entirely. Take closeup photos of the gun from all sides with your digital camera or camera phone to help you with placement of all screws. You will need small clamp, small vicegrips and paperclip or piece of soft wire with small hook bent on one end to temp hold spring in place. With rails in hand check if pusher will slide out front of rails (some rails have a small casting preventing pusher from coming out front ~ remove tailpiece and slide out back ). Locate small screw /nut holding spring in place (keep this side of rails facing you). With new spring in place slide pusher into rails until you can catch the eye of the spring with bent wire at front of rails. While holding wire with vicegrip pull back pusher a few inches and clamp in place with c-clamp. Pull or let in bent wire to align eye of spring to attachment hole and install screw (you can leave bent wire in eye and just break off later. With screw attached break off wire and install rails to gun. Check sliding action of pusher before installing bolts at rear of rails. The pusher on some porter cable guns have plastic sliders that easily break with normal use and should be replaced as needed. Good luck.
