Dewalt uses two vinyl orings against the cylinder spacer seal. Most likely one or both have have failed. These orings are included in the repair kit available thru dewalt service center near you or on the web. If you have a source for orings, like a bearing retailer, you could replace with generic viton orings. Take cylinder and cylinder spacer with you so that you can fit them in. The orings should allow cylinder spacer to fit snuggly and allow the spacer to have about a 1/4 in travel without jamming. If a kit is not available, then only option is to convert to generic orings.

    I also have a leak from the nose. I have replaced all the o'ring associated with the cylinder. Leaks worse now than it did when I started. I have taken it apart and put it back together several times trying to fix it. When I put it together and connect air you can hear the piston get pushed against the back cover, but then it just leaks out the nose. I haven't done any work on trigger. Any suggestions?

Air leaking around trigger


Bad O ring in gun most likely. Usually happens on mine in the fire/reload phase. If its an oil lubricated gun give it a squirt of 3in1 if that doesn't help it will have to go to the repair place..

Dewalt Nail Gun D51844. Same problem as other guy - air blowing out with trigger off. Taking it apart, not sure the cylinder comes off, seems to be held in by a hard plastic housing - called a Bulkhead. ...


Dewalt uses about 4 or 5 orings within the gun made of semi clear urethane that fail (turn gummy and breake apart). Two are under the bulkhead and at least two in the trigger valve. To remove the bulkhead pull up on the white housing. With housing and cylinder assembly out, push down on the black retainer at the very bottom and remove the oring(take a picture of the assembly after each stage so that you can re-assemble the spring and checkvalve correctly). You will find two large orings under the bulkhead against the cylinder that need to be replaced (also the orings in the trigger, or replace the trigger valve ).

Air leek where nails come out


Air leaking out the nose indicates that the orings that seal the bulkhead /cylinder spacer (white plastic ring around the cylinder) are leaking. Order oring kit from dewalt and replace all the orings. I dont remember if the kit containes a trigger valve but it needs to be replaced also or at least have a spare ready when the orings in it fail. Dewalt used some vinyl-like orings that failed (vinyl orings were also used in the trigger valve ). Good luck.

My dewalt framing nail gun was hooked to the air compressor, but was not being used when it began leaking air which you could hear and got louder. It sounded like it was leaking around the trigger area....


There are O-ring seals around the trigger that are probably leaking. You can try to lubricate the gun by adding the pneumatic oil to the air supply. That may be enough to seal it back up. Otherwise the seals and/or the trigger assembly will need to be replaced.

For the Dewalt d51844 can you use PAPER or plastic collated nails


Yes you can generally interchange the two (paper vs plastic collated) as long as the nails meet the specifications (and collated angle) specified by your nail gun.

Air leaks arond trigger when depressed, but no nail fires.


Where does the air leak out from? If it leaks from the trigger DeWalt makes a trigger valve assembly part # 641006-00 list 8.89 BUT if it leaks from other areas we have to look into it deeper. If it is just the trigger valve let me know and I will give you instructions how to remove and install the new one.

D51844 nails jam


The problem that you are experiencing could be caused by several conditions within the gun. Lets work thru the possibilities. First make sure that the nails are correct for the gun. Place a stick of nails on the outside of the magazine with the first nail aligned with the path of the driver. The stick of nails should align perfectly with the path of the driver and also with the magazine. If they do not, don't use the nails. Check with dealer for correct nail. I find that short nails (around 2") will have a tendancy to jamb.
The driver will not travel to top of cylinder if the driver oring/ring is too worn or the driver is bent. The driver should fit snug into the cylinder but be able to travel rather freely . At the bottom of the cylinder check that the bumper is not missing pieces or is cracked. Some nailers have a washer below the bumper that fits snugly around the driver shaft. The bumper and washer prevent too much air from leaking down thru the nose and helps to push the driver back up to top. There is a check valve around the med section of the cylinder that is what actually caused the piston to return to the top with force. You must remove the cylinder to check. Parts are available at www.toolpartsdirect.com. There is also a rebuild kit for this gun. Enjoy

D51844 Framing Nailer won't fire


Adjusting the depth of the nail also changes the amount of pressure that is applied to the trigger pin. This is not actually a problem with the adjustment, however indicates that the orings in the gun are not completely sealing or is lacking lubricant. Adjust depth so that maximum pressure is asserted against the trigger pin. The trigger pin must be pushed all the way in very quickly to fire the gun. Test by removing the trigger and depressing the trigger pin by hand all the way in quickly. Enjoy
