Piston stop easy fix
The part worked great. Make sure when replacing that you clean the gun from all old parts.

Worked exactly as expected
eReplacementParts is a god send, nobody else carries as many parts of older tools that have many, many years of service left as does eReplacementParts. I have found several parts to my older high end power tools that would otherwise be salvaged out. Thanks.

Nail gun repair
The part arrived within a week and the package was in good condition. It was a little pricey but way cheaper than having to buy a new gun. Good doing business with you.

PORTER CABLE finish nailer FN250a PISTON STOP
part I ordered fixed the problem I was having with the pin that sets the nail not returning, part was kind of pricey but cheaper than buying a new nailer, easy to fix , competitive price with other dealer, fast shipping, easy transaction. I will purchase from ereplacement for future needs of parts, satisfied customer here
p.s. when you open your nailer and theres hundreds of pieces of white plastic, that is more than likely your piston stop, look over the parts list/blueprint before ordering

In addition to a new piston bumper and manifold gasket I installed an O-ring kit. I started with the firing mechanism valve assembly which unscrews from the body using a box wrench. I cleaned the valve and fitted new O-rings the lubricated and reinstalled. When there was still a problem I disassembled further and found that the piston
... Read morebumper had been dissolved after someone had tried to clean the tool with solvent. I removed the manifold cap, piston and cylinder and flushed the unit with WD-40. I wiped and dried all pieces then lubricated all O-rings and reassembled. The most important thing to remember is to properly reinstall the neoprene band that covers the small holes in the middle of the cylinder. The band acts as a one-way valve allowing the pressure charge to vent into the outer cylinder chamber where it then forces the piston back up completing the firing cycle. Everything else is step by step except for the band since it will slide out of position during disassembly and unless you know where it goes back your tool will fail to cycle. A little study and you can figure it out if you don\'t know.
Removed the bolts holding the top cap. When I removed the top cap, I found that the piston bumper was broken. I then cleaned out the all the broken pieces.. I then installed the new bumper, replaced the the top cap. Now the gun works great.

Porter Cable finish nailer was missing every other nail, and then every nail. Took it apart and piston bumper was falling apart.

Install new bumper, make sure when installing top portion of piston not to dislodge o-ring, I did and it leaked air when I put it back together, took back apart and saw it had pulled out, just take time and align piston when installing, goes in easy and properly.

The bumper that stops the upward movement of the piston broke apart
I removed the top cap of the nail gun. Then I cleaned out every darned piece of that broken piston stop. Installed the new one, and oiled it all up. And put the top cap back on. Works like a charm now.
