You will need to remove the trigger before driving out the roll pin. After you remove the trigger and roll pin, place a rag over the trigger, remove your hand from the area, and briefly hook up your air line. (Clean your soiled pants after this part) You will hear a loud pop and the trigger assembly is going to come out quickly. If you are not prepared for this it will scare the **** out of you. Then once you have the trigger assembly out you can push the two retaining pins on the assembly out and remove the inner workings of the trigger. One note of caution. The ring you are trying to replace is a hard half moon looking ring that Bostitch doesn''t sell separately. You may see it in pieces when you take this assembly apart, or you may not. Sometimes it crumbles and comes out of the trigger exhaust. You can try to match up an oring to sit in there, but from experience it is much easier and less costly to just order the whole trigger valve. Hope this helps.

Leaking air behind the trigger


If you take the gun apart you will see a small o-ring on the trigger side that needs replacement and possibly the spring on the media adjuster side as well

DeWalt D51823 nailer leaks air and shoots continusously


Common problem with dewalt due to vinyl orings. Simple tests to determine if trigger valve may work before re-installing. With trigger valve in hand, depress the trigger pin and hold. The bottom of the inner spool is visable in the opposite side from trigger pin and should move inward slightly with little effort when you push it (spool should have almost no movement inward before making contact with body of valve ). If the spool moves inward 1/16 to 1/8 inch, most likely the oring is too worn and not making contact with body of valve (when under pressure, this spool is held against body of valve (closed), and will open when pin is depressed (firing pin pushes on the spring and spring pushes open the valve) ). Next take valve apart and pull out the spool (spool should be difficult to remove from lower body of valve). With spool in hand push upper part of spool into the cap, should fit snuggly. trigger pin has two orings. The upper oring should fit snuggly into cap and lower oring snuggly into spool. The two orings on the pin are made of vinyl and fail. Notice that the spool has a small hole at the bottom. If the pin oring s bad air will leak past pin. Replace with 2mmx1.5mm black oring. After replacing the two pin orings, make sure the pin fits snuggle in the cap and spool, if not , replace the whold valve. The spring is usually good, but if rusty, replace the whole valve unless you happen to have the exact spring in good condition. The two outer orings on the body of the valve do not have to be replaced unless cut. Good luck

All the sudden the nail gun stop working, pull the trigger air leaks out at trigger area


I had a similar problem with one of my nail guns. What I found was a small rubber o-ring in the trigger mechanism had split. Once I replaced this the problem was corrected and the unit functioned fine.

You could replace the whole trigger assembly for about $35. But if you remove the assemble and replace the split-ring this would only cost a couple of bucks at most.

Trigger assembly shown below. ereplacementparts.com is one possible source for the trigger assembly others can be found on the Internet.

Gun leaks


Hi, there is a spring in the handle, to enable the trigger; is this what you mean. If so look to see how the trigger works and there is space for this sping to slot into. It can be quite fiddly to get this right!

Karcher 1650 leaking water from trigger


i believe the spring is the actual trigger spring that pushes the trigger switch back in place and the water leaking out is probably a seal issue

Air is leaking around the trigger. N60FN. How do you replace it?


Yes, you have to drive out the pins. There currently is no rebuild kit. Depending on when your was built there are solutions though.
Carefully drive out the trigger pin first. Then the one retaining the trigger assembly. The trigger assembly is in there pretty good, carefully work it out. Once you remove it, there are two small steel pins holding it together. Remove those...careful there is a spring inside. You can see what's been compromised. Like I said, there don't make repair kits for these, but you can order a replacement assembly.

Good luck.

Dewalt 51844 round head nailer


Could be a couple things, the seal ring on top of the cylinder or a cut oring or just a faulty trigger valve assembly. I would take it back and have the repair shop correct the problem for you at NC. Let me know if still a problem and I will look at a schematic and give you part numbers.

couple of things there are o-rings inside that trigger assy. they are either pintched in or dry. next there could be internal rubber hoses inside the gun. might need replacing. lastly the hose or o-ring going to the back side of the ram is leaking or broken. here is what i would do. you sound pretty handy with your tools so i would get somewhere clean start taking the gun apart thouroghly noting where everything went and go untill you find the problem. but first i would shoot a couple of drops of oil into the air input on the gun then hook it up and fire a few off and see if it clears up, if not then start takeing it apart. I CAN NOT STRESS ENOUGH....DO THIS ON A CLEAN SERFACE WITH YOUR HAND CLEAN. i chased a leak around in a pnumatic hammer for 3 days all because it wasnt clean on the inside..
