Framing nailer repair


I have a Dewalt D51844 framing nailer. It will no longer shoot nails. When I press the trigger, I can hear air coming out of the trigger area. Is it easy to repair framing nailers?

Framing nailer repair


if youve never repaired a nailer best not try it . you could easily make things worse by not putting it back together correctly..

by the sounds of it you might have a bad oring

I was doing some research and it could be the trigger valve or o-ring around the valve.

It doesn't seem like it is too bad of a repair. I may try it. If not, I'm just going to throw it away. I don't want to pay for it to be repaired.

It's almost always just an O-ring. Cheap, simple fix.

your right joe, i forgot about that.. the dewalts have interchangable triggers to suit the user if they want bounce fire or single fire mode.... i dont get having that on whats supposed to be a pro grade tool.. its probably why dewalt doesnt sell many framing guns.. along with the fact they jamb easily

I finally got around to looking at it. The trigger valve assembly is leaking. Specifically, there are two clear o-rings inside the trigger assembly that have deteriorated. I can't find the o rings sold separately from the valve. Where can I find this type of O ring? Unfortunately, the o rings fell to pieces, so I can't compare it to anything. I was thinking about checking a tool repair shop.

No way would I just replace the trigger o rings while I had it apart.
Buy the whole rebuild kit and redo the whole thing.
I get the whole thing done at a factory authorized repair shop for $75.00.

It's really easy to remove the trigger guard and valve. You could save money, and more importantly down time, by doing it yourself. You just have to remove a few pins.
