Question about Air Tools & Compressors

1 Answer

Help I have a bostitch N80 coil nailer that leaks from the main part that is held together by the 4 allen bolts, I have checked the tightness and when i re tighten them the leak stops for a while then reappears soon after. I think the operation of the gun loosens the allen bolts. I am unsure as whether or not their should be a silicon gasket smeared before the two parts of the gun are reattached? Or should it just be a bare metal contact between the two? Thanks Neil

there is an oring gasket that fits in the groove of the N79 N80series coil nailers. It is easily pinched if not put together correctly. Use a lightweight grease in the groove to hold the oring in place upon assembly.

How do i rebuild my bostitch n80 frameing nailer

Bostitch nailers are simple to rebuild. Bostitch company was sold to Dewalt so parts are now easier to obtain from local Dewalt service center. Use Ork11 oring kit and tva6 trigger valve. These parts are also available on ebay. Good luck or your nailing projects.

Trigger leaking air and trigger does not work

Try adding some transmission fluid to the air inlet. Just a little squirt in the air nipple. Try the gun, if it doesn't work it may need a new o-ring kit. they are relatively easy to replace. Also make sure the allen head screws are tight. These hold the body of the piston assembly against the seals. If air is leaking from this area the gun will not shoot. The seal rebuild kit comes with installation instructions.

I Have a N80 Coil Nailer. It was given to me without the manual. I down loaded a manual, however it is not clear how to set the nail depth. Can you advise?

Bostitch nailers used three methods to adjust how deep the nail will set. On stick nailer, there are one or two screws on the lower contact arm allows you to shift up or down. On coil nailers and others , there is thumb screw on side or under the trigger. Finally on some coil nailers, there was a series of spacers that snapped onto nose of the gun. Good luck

Where is the serial number on bostitch coil nailer?

The serial number on the coil nailer is towards the air nozzle on the handle. There is a little bridge of metal connecting the main body of the gun to the plastic coil housing. The number is laser etched into that metal.

I have a bostitch model nc65 coil nailer. It is having problems returning the piston to the top position and I believe that a reed valve or seal is missing from above the head valve. I can't find any...

Can you verify the model number please? I only see references to N64 or N66 for coil nailers.

Specific to the problem listed, this is usually caused by an air leak through the O-rings. I would replace the O-rings and make sure that the entire area is well lubricated with pneumatic gun oil and try again. This should resolve the problem.

Leak inside Bostitch N80 Nailer, won't drive nails

If the unit is leaking it most likley need a rebuild kit. Go to a Bostitch service center and ask for an ORK-11 kit. That is all the o-rings needed to do an over haul. Or just have them do it.

Leak from Bostitch coil nailer

On Stome bostitch there is a rubber oring gasket that fits in groove and others have a thick paper gasket.
Sounds odd that it stops then starts again. try a gasket and inspect to make sure the head it not cracked or was hit with a hammer
