Question about Dewalt Heavy - Duty 31° Clipped Head Framing Nailer - D51822

1 Answer

Dewalt D51822 fires once only

I put a gasket kit in this well used nailer. The nailer will fire the first time but the piston driver stays in the down position and does not retract. If I retract it manually it will fire one more time and stick again. Any suggestions?
Thanks,
Bud

Hi Bud, This is a common problem as they get older. The mechanisms get a little worn and they pick up a lot of debris, especially the stick nailers. I have had an old bostitch for over 20 years and instead of rebuilding it all the time, I have taken to cleaning it regularly and taking it apart once in a while and wiping it with steel wool to check for any burrs and tiny pieces of the stick wire. The best results I have found are to wash it down with an engine degreaser and blow it out throughly with compressed air and then relube with pnuematic tool oil, especially the piston. Also be sure to put a few drops in the air inlet each time you connect it so it lubes the piston from the inside. Take out any nails and fire it several times onto a piece of wood to make sure the lube reaches everywhere. If you get a little too much inside it will spit it out as you nail but for framing that is not a big deal and I would rather have a little more than not enough. Good Luck, this should Fixya!

Again sounds like blown O ring give it a squirt of 3in1 oil and fire it several times (if oil is compatible in your gun). Repair center if that doesn't work. Trash can also get in the air orifice and stop moving parts from moving.

Dewalt nailers use some orings that are made of vinyl (clear to yellow in color instead of buna or viton). These orings fail by getting soft and sticky. The gun may not leak but will not work correctly. The trigger should fire the gun when depressed about 1/2 way in. The oring repair kit has the same orings. I use generic orings in the gun to solve the problem. There are two orings inside the gun that should be changed and at least two on the trigger valve stem. In time the gun may fire a nail when you connect the hose. Check the internet for recall on some of these guns. The orings in the gun that should be replace make contact between the white cylinder spacer and the cylinder (smaller is standard oring # 141 the larger is 74.4mm x 3.1mm). The two rings on the trigger stem are 2mm x 1.5mm . If you do not have a source for orings then just replace the trigger valve. You also might try setting the depth adjustment all the way down. Good luck.

D51822 plunger will fire (and impact wood) but will not retract enough to grab/push out a nail.


Dewalt nailers have some vinyl orings that fail. Usually found within the trigger valve, headvalve, and between the cylinder and cylinder spacer (white plastic piece). A dewalt nailer with failing orings may not leak air however. The vinyl orings tend to start to crumble and the tacky-crumbling pieces tend to create a seal. Easy way to check condition of the vinyl seals in a Dewalt is to remove the trigger valve and look at the orings on the firing pin/stem (2mmx1.5mm orings). If these two orings are soft and sticky, then orings inside of gun most likely the same. Check band on the outside of the cylinder (part # 390159-00) is what causes piston to return to top. But also check to too tight or too loose piston oring, bent shaft of driver and worn/ broken lower bumper. If all is well with internal parts and piston does not return to top, too much air is leaking past nose of gun. Oring kit sold by dewalt will contain most of the orings needed. The kit may not have orings for the trigger. You will at need two orings (2mm x 1.5mm) for the trigger valve stem or just replace the valve. Use white grease or silicone paste lube on all the orings. Good luck.

It will not fire the nails. Unit is cleared with no obstructions. This has happened several times but now it will not work


If your gun is over a year old, you may have failing orings. Dewalt used vinyl orings (yellow to gold in color instead of black rubber) in the gun that fail. The vinyl orings are installed around the cylinder and inside the trigger valve. The gun may not leak air, however will not fire. The repair kit has all necessary orings, however may not include the trigger valve. Good luck

DeWalt D51822 Framing Nailer: Replaced the trigger valve and air is still coming from the nose of the gun. I would think no air should get past the trigger valve until pressed. What's wrong?


Dewalt framing nailers use some vinyl orings (gold or clear in color) that fail too soon in both the trigger and the cylinder spacer. Air out the nose of gun indicates air is leaking past the cylinder spacer seals (If piston is pushed down with air leak then headvalve seal is leaking (remove nails for this test)). If piston is not pushed down with leak, remove head and pull out the cylinder with cylinder spacer (white plastic). Place the cylinder on workbench with bottom up. Push down on locking ring and remove retainer to release all the other parts. Take picture or take note of parts together and as you pull them off to aid in re-assembly. You will need to replace the two orings between the white cylinder spacer and the cylinder. Order oring kit from dewalt or just purchase one ( # 141 universal oring ) and one metric oring 74.4mm x 3.1mm from hydraulic parts store. If the piston was pushed down with air leak, replace headvalve orings in the head. Good luck with your repair

After shooting a nail, it fires out two more nails. It's a Dewalt d51822.


There is a replacement trigger valve available from Dewalt. The new part number is 5140095-73 (the old part number was 641006-00 ). I am not sure however if the new part is just a natural upgrade or if it was changed to address an issue. I have seen these guns double fire and fire once when air is connected. I would change trigger valve and four orings that make contact with the bulkhead (part # 395215-00). These orings are in the repair kit available from Dewalt (kit does not include the trigger valve). Use caution for now, do not load nails until you are ready to nail; then pull out nails from rails when done . Good luck

Generally when the trigger makes a pop sound when you fire the gun and driver does not activate is indication of failed orings. There are two orings on the trigger firing pin and two orings on the cylinder that are made of vinyl and fail. All the other orings in the gun are black rubber like compound and last for a very long time. The two orings that fail within the gun are included in the repair kit and the trigger valve will most likely need to be replaced, or you could remove the valve and change out the two small orings (2 x 1.5 mm). If you would like to attempt repairs, email and I will give you detailed instructions. Main problem is that the replacement orings will be vinyl also and will not last very long. Good luck

As I try to fire the gun, I just get a small thump of air and no nail fires This gun is 2 years old and worked perfectly when I put it away last spring.


Problem you describe is typical of stuck driver or firing valve. Easy to check; remove head and make sure piston moves down cylinder (upon removing head, piston should be at top). Your gun utilizes sliding cylinder instead of moving valve in head. When you pull the trigger the cylinder moves down allowing air pressure to drive piston down. Orings swell overtime which prevents the cylinder from moving/firing. If cylinder does not move down/up, may be time for rebuild kit. Parts are available at dewalt service center or can be ordered from www.toolpartsdirect.com. Good luck
