How do i get the cylinder collar of so i can change o-rings under the BULKHEAD ?

    It was the removal of the cylinder collar I was referring to.

    But I solved it you just pushed the collar backwards until you could see a o-ring. Then you simply removed that o-ring, it was the o-ring that hold the collar in place. After that you could just remove the collar, spring and finally the bulkhead from the cylinder.

    It was an o-ring under the bulkhead that where damaged.
    The nr:74 on the dismantle schema.
    This caused the nailer to blow out air through the nose all the time when air was connected.

    (To bad you cant post pictures here)

You have to remove the cylinder. To do this use two flathead screwdrivers on opposite sides and gently pry the cylinder out being carefully not to damage anything. If you have to replace the oring on the bulkhead it takes a little bit of finesse to work it out of the head. I usually put the nailer in a vise and use both hands, two fingers from each to pull the bulkhead out. It's not easy and you will bust your knuckles.

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

I have a d51822 framing nailer that will shoot a nail but then not recoil to shoot the next nail, if you wait 10-20 seconds the gun will release air at the top of the gun and recoil

Most likely there is a problem with swollen orings between the cylinder and cylinder spacer (white plastic piece between cylinder and body ). Order the oring kit because nost likely when you take the gun apart the orings will fall apart. Dewalt used vinyl orings instead of viton on critical areas of the cylinder and these vinyl orings failed.

Either the plunger has not completely returned to the "pre-firing" position, or there is a defect in one of the o-ring seals. Make sure that the gun is sufficiently lubricated and if so, then next check the condition of the o-rings. An improper seal will cause this. It is also possible that the trigger assembly has a small crack/leak.

Don't know if this will help you but here goes. I have a Bostich nailer and had to replace the check valve under the trigger.(at least it acts like a check valve, stops air loss when disconnecting gun from hose) It was leaking badly and had to remove trigger to replace the kit. You can do it yourself like I did or take it in to a shop. I carefully punched out the roll pins, replaced the kit after greasing the o-rings with lubricant that was supplied with kit and replaced the trigger.
Good luck

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.
