Senco SKS gun (mid 90'). Remove four alan screws at the top of the cylinder and everything pulls straight out without any other tools. The old plastic piston is no longer made and the seal is no longer available for it. Since that was the main problem with the gun, I bought the new style aluminum piston. It slides right in. Lube all the rubber with silicone o-ring lube. Good as new again.

Removed the cylinder from nail gun and replaced a couple seals that were in shards from Old Age with new ones and put nail gun back together and it works like it did in 1967 when I purchased it. If you go to the website ,all you do is punch in the model and whatever information in and it comes up with a schematic of your tool for parts and part numbers for all parts in the tool. Follow the pictures and you can rebuild almost any tool you might own. Their Staff is very Helpful and Courteous too !!!
