Question: Rebuid Or Repair Kit?

monvinyl

I have a leaky gun, what's the difference or which should I get, the repair kit or the rebuild kit?
WJA
Reply: Rebuid Or Repair Kit?

WJA

Hello 1117710,

First of all it depends on where you have the air leak. If it is in the trigger area go with the TVA6 Trigger valve kit. If that is not it I would go with the RN45/SDC [RBK13
Hope this helps,
-WJA

Question: Trigger Valve

cody

Air dumps out of the trigger when pressed; the driver does not move. I changed the trigger valve, same problem.
my nailer is a bostitch rn45b-1 when you plug the air hose in, it will shoot one nail. It starts blowing air if you unplug air hose and plug it back it will shoot one more.

Question: Feed

My RN45 is breaking nails in half and not feeding. Can someone please help? Thanks.
Tom
Question: Trigger

Tom

How do I get the trigger "O" rings out. Is it the bottom drive pin I need to knock out?
Ron
Question: Trigger

Ron

When I hook up the air I get blow by around the trigger and it will shoot one nail but the hammer won't return.

Question: O Ring Replacement

frank

My nail gun leaks air from the trigger. I need to replace the o-ring but I am not sure how to do it?

Question: Driver Not Returning

mark

I installed a new rebuild kit and now the driver will not return after the gun is fired. The driver feels free, not real tight.

Try replacing the cylinder.

Question: What Part?

scott

My friends Bostitch rn45 will shoot but will not advance the coil. What part or kit does he need? Thanks.
brian
Question: Failure To Shoot

brian

I have a Bostitch roofing gun that when I plug in the air hose and get ready to shoot the gun, it is like the air is not engaging the gun to fire. The pin behind the trigger doesn't seem to be coming out so when you put the gun down to fire there is no action.
Mark
Reply: Failure To Shoot

Mark

Hi Brian,

I would suspect that your trigger valve has gone bad. There is a kit available that will replace the entire trigger valve. It is part #TVA6 and is available from http://www.ereplacementparts.com.

Good luck with your repair!

Question: Jammed

BOB

The gun is jammed with part of a roofing nail sticking out.
RON
Reply: Jammed

Pop open your feeder and remove your coil of nails. Check to see if only one nail is in the barrel, if so close your feeder and dry fire the gun to shoot it out. These drivers are very strong and I have done this before on the job site. Or if that's to exciting pop the feeder and use a nail set to tap back the head of the stuck nail until you see the head where the feeder is then pull out with a needle nose. Check your feeder and driver tip. Guns don't just jam on there own, something else might be going on.
STEVE
Question: RN45B

STEVE

I loaned out my roof nailer and he tells me when he hooks up the air hose to it it blows continuous air out the nail discharge area. It still will nail but will continue to blow air out until the compressor is drained. Thanks. Steve
Ron
Reply: RN45B

Ron

It will need a front o-ring Steve. Get the full kit and replace them all. Also,don't let the gun sit for long periods, drop 7-10 drops of gun oil in it and run it once a month so the seals don't dry out. Download a pdf to see how your gun is put together for the ring job.
Alice
Question: RN45B Trigger

Alice

Hi. My above modeled nailer has an air leak in the trigger. What parts do I need to repair it?
Mark
Reply: RN45B Trigger

Mark

Hi Alice,

I would suspect that your trigger valve has failed. The trigger valve is offer as a kit. The part number for the trigger valve kit is #TVA6 and is available from http://ereplacementparts.com.

Good luck with your repair!

Reply: RN45B Trigger

Ron

TVA6 trigger or just the o-rings. You can get them on this site. A full o-ring kit for the gun should have the o-rings for the trigger. the trigger is simple to replace/rebuild and other o-rings,especially the driver will go as being used so it's good to have a full o-ring kit for less down time. Download a pdf on this gun.
I have a bostitch n45b that will fire one nail but won't advance the nails. I have checked the coil of nails, cleaned things up a little. What might be causing this? I'm not exactly sure how the pawl works so don't have a clue what the problem might be.

Inspect the feed pawl itself for broken teeth and make sure the pin which attaches the pawl to the shaft of the nail advance piston is present and that the ""O ring" retainer is on the end of the pin.

Check for an air hole obstruction on the inside bottom of the frame. This is a small hole which feeds air to the advance piston and could become clogged if the bumper has disintegrated.
