how do you take out the head cap gasket?

Question: The Man

mikey1952

Hitachi NR83A2(S)The feed guide on my nailer started to spred a part allowing the nails, especially the small sizes to fall down in the feeder. I thought it might be an easy fix so I took it a part now I'm not sure how to fix it and know I can't put the ribbon spring and needle roller assembly back without some help!
The nailer has not been used to much and I am the primary operator, can't see how this would have happened?

Question: Premature

kiltboy

I've had this for a few years and probably under oiled it in the past.
now when I use it and then stop, anywhere from a few seconds to a minute the nail will slowly start to creep out of the firing area.
then I have to set up gun to fire, weight it down to force the nail and piston back and then fire, or strip out nail and dry fire.

Anyone know which o-ring/seal needs to be replaced.

Thanks

I had the same problem and it was an easy fix. Two small o-rings were worn out. I replaced them and works fine. Had to drive out the two pins in order to get at the trigger valve. Just used a small nail to do so.

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?

Reply: Rebuilding Hitachi Nr83aa- Rippe...

Tinkerdave

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.

The piston driver on my tool does not retract like it should when bump firing the tool. It hangs up until I release the trigger, then retracts as norma. It acts like a sequential fire tool. Something weird in the exhaust system? Any ideas? I just cleaned the tool and replaced all rings and packings. Thanks, Mike.

[QUOTE=americantoolman;5093]The piston driver on my tool does not retract like it should when bump firing the tool. While holding the trigger and pressing to wood it fires but hangs up on return. If I fire like a sequential fire tool pulling the trigger each time it fires and retracts like normal.

I just cleaned the tool and replaced all o rings and packings. Changed out cylinder seal and rechecked trigger parts. Now I'm begining to swap out parts - process of elimination. Anybody seen this before? Any ideas? Thanks, Mike." Thanks, mike.

Hi Mike,

I am stumped with your problem as well. I can't figure why the gun would fire OK sequentially but not while bumping. Many issues with nail gun pistons not returning are caused by the trigger valve. You might want to check there for bad o-rings or maybe debris from worn part elsewhere in the gun.

Sorry I can't be more help. Let us know how it turns out.

Good Luck!

Finally figured it out. Simple really. The adjustable screw on the push lever was too far out, eventhough it was just short of the valve bushing it would not allow the plunger to move out enough to fully cycle the tool. I guess the push lever was out of play while firing sequentually.

Good to hear that it was nothing serious. I hadn't though of that. Makes sense though.

Thanks for letting us all know what the solution was!

Question: Hitachi Framing Nailer

AntV

I replaced the drive piston on my Hitachi framing nailer and now when I hook up the air, it just engages the piston and passes air. It doesn't cycle. Anyone got any ideas?

Reply: Hitachi Framing Nailer

Hey AntV,
aside from taking it back apart and reassembling a few times..:) try holding down the trigger with the safety engaged.[no nails and pressing down on some wood]and then hook the air back up..this is an old repair trick from the factory techs..also make sure your o-rings are lubed of course..
hope this helps...
Craig
I took apart the strip that holds the nails and thee ribbon spring came off I can not figure out how to put it back on. Any one with suggestions or video? Thank you
