Is your Hitachi NV45AB or NV45AB2 framing nailer acting up? Maybe it's not firing right, or there's a weird noise? Instead of buying a whole new tool, often you can fix it with a simple parts replacement. This handy kit contains some of the most common wear parts you might need for a rebuild. It's an aftermarket kit, which means it's compatible with your Hitachi but often more affordable than OEM parts.
So, what's in the box? You get a replacement Piston Driver (fits part number 878-156), a Piston Bumper (878-179), a Feeder Spring Set (which includes the spring 877-761, shaft 877-825, and ring 877-826), and a Bumper Sheet (877-993). These are the parts that take a beating with every nail you shoot, so they're common failure points.
If you're handy and comfortable taking your nailer apart (maybe with the help of a YouTube tutorial), this kit can save you a ton of money on repair bills and get your favorite nail gun back in action. Just make sure your nailer model is the NV45AB, NV45AB2, or NV45AB2(S) before ordering. Keep this kit on your shelf for the next time your nailer needs some TLC. A little maintenance goes a long way!
