Hello binar,

In answer to your question. The part number 894742 are sold individually and are not sold in a pack.

-WJA

I have a Porter Cable BN125A Finish Nailer that when the trigger is pulled will only make a clicking/short burts of air noise. I have checked the piston and the air supply which is fine. Any suggestions???? Almost acts like its not getting enough air but I know it is.

Thanks for any help :confused:

Hi Fire8033,
There's a couple of things to check on this tool . Take the nails out of the tool then place the nose of the tool on a board and press down and engage the safety while pulling the trigger.While your doing this connect and disconnect the air hose a couple of times and see if the tool starts working.What this does is check to see if the head valve is cock in the head and not being allowed to move in the head.If that won't help take a small screw driver and slide it between the trigger and trigger valve and see if the tool can be fired manually.This checks for bent or worn linkage on the trip arm. If it still won't work remove the head and with a wood dowel or other soft object see if you can move the piston up and down the cylinder.This checks for any nail or part of the nail shank being stuck in the channel of the magazine blocking the cycling of the driver. One of these things should be your problem.Hope that helps.Good luck.
Tinker

Question: Porter Cable BN 125A Finish Nail...

Hello,

I have a porter cable BN125A and the nose shoe recently just fell off. I don't know if its missing a piece or something but I cannot get it to stay on for anything. Does anyone know if they just slide on and stay or are they supposed to be glues or something. The nailer works now but marks up the trim I am nailing.

Hi Wes,

The cushion does just slide on. There are two grooves on the inner sides of the cushion that slide around the metal nose piece. Make sure that the nose piece slides into the grooves and it should stay put.

I hope this helps!

Question: Brad Nailer Won

Rudy

I have a brad nailer, model #BN125A that no longer fires. Upon examination of the piston, there appears to be a crack on the o-ring. Will this cause the malfunction?
Thank you

Question: Brad Nailer Not Firing

monty

I have a Porter Cable brad nailer #BN125A that I had not used in a while. I loaded a strip of nails and nailed 2 or 3 nails and it stopped sending out nails, it sounds like not enough air pressure is going through it, what could cause it to do this?

Question: Porter Cable Bn125 Pinner

dennis roth

air seeping out rear housing cover. cant get off,tried impact gun & pipe wrench! wont budge.whats up here????

I have a Porter Cable 125A brad nailor in an unheated shop. It leaks air continuously out of the top ( above the piston ) when I try to use it in cold weather. Is there a temperature limitation below which these things don't operate properly or do I need a repair. Right now my plan is to bring it inside, let it warm up and try it.

Hey kripm,
most likely you need to service your tool..parts available at ereplacementparts.com..they have individual parts along with an overhaul kit if needed..
colder temps are hard on all kinds of tools..and especially air tools...they also make a winter oil for pneumatics for really cold temps..
hey..spring is almost here..!
hope this helps..:)
