Question: Hitachi NR83A

Fixthisnailer

I have an old school 3-1/4” framing nailer that is over 20 years old. The driver drives the nail only once and The driver doesnot retract. I have to remove the nails in cartridge, then manually push the driver back into position. What part or parts is causing this, & is there a piston rebuild kit?
WJA
You will need to remove the top of the gun, To see what parts are worn or broken. Such as o-rings, seals, piston bump etc. There is an o-ring kit available but no driver/piston kit
Question: Air Leak

chiselcreek

I have a major air leak around the trigger. When I hold the tigger in the air leak stops and the gun will bump nail. When I release the trigger the air leaks and the gun will not build pressure. I change the two o-ring in the trigger area and clean the ball. Any help?
WJA
Hello chiselcreek,

There a quite a few parts involved with the trigger. Check them all for wear. Hopefully it will be one of those parts.

Good luck,
-WJA
Hi chiselcreek,
Replace all the trigger parts as wear in this area is accumulative and you will drive yourself nuts guessing at what part is causing the problem. Even if you do find the part causing the problem you will have future problem in this area if all are not replaced together.Hope this helps.Good luck.
Tinker
The urethane ball sits in a packing, or seal. It's probably deteriorated.
Question: Leak

dizj1

I took apart my NR83A and replaced all O rings and most gaskets. Including trigger o-rings. Put everything back together and I have massive air leakage from exhaust draining my compressor pressure. Any ideas?
Hi dijz1: Did you replace O-Ring (S-90) Part Number: 877-316? This is the bulkhead O-ring where a lot of leaks are from.Also does the tool shoot ok other then the air leak?Knowing this will help us troubleshoot the tool better for you.
Tinker
The cylinder on the Hitachi move up and down to fire. Most likely you need to turn the gun upside down and "whack" the top of the gun on a piece of wood to cause the cylinder to seal to the head valve. If that does not work you will need to replace the head valve (877-307).

Question: Rebuilding Hitachi Nr83aa- Rippe...

henriksen2008

I have to replace the cylinder ring on this nail gun, but since it was ripped i'm not sure where it goes on the cylinder. I think it goes over where the small holes are?
Hi, Yes it goes over the holes and is a cylinder check valve for return air. Nail guns use low pressure to pull the piston driver assembly back up to the top of the cylinder and this check valve helps it do that. Hope this helps.
