Question: FN250A Check Seal

1531096

Hello,

I purchased a drive maintenance kit for my FN250A nailer. When removing the cylinder, the check seal fell out before I could see how it was attached/aligned. Now I do not know how or where to place it on the cylinder. Neither the schematic nor video clarify how or where is goes. Can you help me please.

Question: Porter Cable FN250A Leaks Air

sigala

I have a Porter Cable FN250A gun that I started to use, I shot one nail, and then it would not load anymore,
But would fire, I saw that the driver was not retracting, I unscrewed the top housing assy, and found crumbled plastic, a hard waxy feel to the plastic, it was all in the bottom of the upper piece where the piston spring sits, I cleaned all this debris out of the housing thinking it was some wax buildup over years from the oil? re-assemble and now the gun leaks air out the port on the housing, reading the forum, many have said that it is the piston stop item 114? does this have anything to do with the air leaking out the top. I'm going to replace this and HD valve O-rings. since the driver assy was working.Where does this piston stop sit in relation to the cylinder under the cylinder cap there are 2 cylinders cast into the cap where the piston slides into outer and inner the cast cylinder on the inner diameter has 8 teeth.
I believe is where the bearing washer sits? Would be great if someone did a step by step youtube of this model.
I do not want to start buying repair kits since they now cost almost as much as a new gun.

Hello Dennis,

We have prepared an article and video on How to Install an Overhaul Kit in a Porter Nail Gun. This should help you with the installation of the 886113 Piston Bumper.

Does this apply also to the FN250A Finish gun>
WJA, thanks for the help on this, after viewing the video, I see why the leak is occurring since the piston stop is gone,, it would leak! So I will order the parts. Piston stop and O-rings.
will let you know how it all turns out.,
Thanks again!

Question: PC Finish Nailer

wargle

My finish nailer FN250A stopped driving. Took the top off and found a nylon plug about 5/8" long and 1/2" dia. crosswise on top of the driver. Also, the piston bumper was crumbled. In looking at the exploded dwg. I don't see anything the looks like the nylon plug. Any idea what this is and could it be part of the piston bumper? Thanks.
Hi wargle,
There's no telling what that is .It could be the head valve bumper. Can you email us a picture of it?Thanks.

Question: Bent Driver On Porter Cable FN25...

munionman

My driver was not retracting after setting a nail so I opened it up. I found the plastic piston stop had deteriorated and was in pieces, but I also found the driver itself has a slight bend to it. I assume the driver isn't supposed to have that bend in it. If I just replace the piston stop, can I try to straighten the driver in a vise or do I need to order a replacement driver kit, too?

Hello 1054592,

You can order the 886113 piston bumper. And try to straighten your driver. You will find out the first time you fire it, if it worked. If it didn't do the job then you can order the 903767 driver maintenance kit. The driver has to be as straight as a new one to work properly. Or it may damage other parts inside the gun.

Question: Porter Cable Nailer Model FN250A

My nail gun was not working properly so I removed the top cap and found some rubbery subastance there that appeared to resemble deteriorated plastic. Could htis be the piston stop Part #886113. Does this come in the rebuild kit for the driver?
Thanks,
Sam Maggio
did you get an answer, and was your problem the driver not moving back to its normal position

Hello 1023832,

The part number 886113 bumper is sold individually. And is not included in the 903767 driver maintenance kit.
