Slight drop off issues

[factoid]

Use Tri-flow on everything bro. All your orings. The oil that came with the mag will gum up if left sitting for a long while (turns a green sticky color). Tri-Flow w/Teflon is money, a little goes a long way and no worries about it turning into jelly. I been using it for a good 5-6 years now with ZERO issues, best stuff ever.

There's always good reason to re-grease the spring pack. By using oil on the pack all that's required is a drop down the Reg vent hole to keep it in tip top performance. I lube it every time I lube the marker before a day of play.

I don't get to play too often anymore unfortunately

Would you actually degrease the pack before putting tri-flow on it?

I've never seen a recommendation to use grease on the o-rings throughout the marker before, that's interesting. You apply that manually? When I lube up my marker I usually just drop a few drops into the ASA and dry fire it through the marker, but that's probably not the way to apply grease I'm guessing.

You have the grease type Tri-flow? Use the oil version.

EDIT:But the grease version will be perfect to use on the pack if you like.

You don't grease the orings in a mag. Grease is too thick. Only use light synthetic oil. The grease is only for the spring pack. If you use a good quality grease that will not dry out, it will last for years. The grease isn't for lubrication of the springs, but the oil is for lubrication of the orings. Applying oil in the ASA is the best way to cycle oil through the mag. It makes sure the oil goes through all air passages where orings seal.

Don't reuse old regulator seats. They have a groove pressed in the front where the regulator pin seals. You can never get this groove perfectly lined up and it will leak. When you install a new seat the surface is flat. The pin will seal great against this flat surface and eventually create a new groove. If you move the regulator seat once this groove is created, you will have to replace the seat again. This is why it is always recommended to replace the regulator seat on a classic mag whenever you have it apart (unless it is a brand new seat).

I wouldn't call it a recommendation as much as a "it can work" sort of thing. A long time ago, I would try to get by on a thin coat of grease, but whenever there was a question on the field, oil would get added. Synthetic oil throughout is better nowadays.

The grease was "hand rubbed" on each o-ring, most of it being a very expensive variety called Krytox, a severe duty teflon based grease. Expense being another reason to hand rub a thin coat. Back when we shot CO2 all the time, you would still get gas penetration in urethane o-rings, and synthetic oils were not so common. Coating the o-rings with synthetic grease slowed the gas penetration and also helped slow damage from the hydrocarbons in some of the oils we used.

I still use superlube grease in static o-ring seals, like on/off base, reg body and power tube tip. I also use it on the little black level 10 carrier o-rings. It's good thing for o-rings that have to go over or through threads. If it collects a little dirt, it's not moving to cause wear anyway. All the moving seals definitely get oil now.

But if you don't already have a box full of greases and oils, the new synthetic oils work on everything. I occasionally feed a synthetic air tool oil through a couple of my electros, solenoid and all, just because it turned out thin enough to get an old noid running again.

Like athomas says, don't re-use old reg seats. However, if you can keep them in a separate place, they can be handy at times. I've re-used one in a pinch; for whatever reason, the old grooved seat held better than the new seat at the time (probably just clean vs. dirty). I've used one as a 12 gram seal on a splatmaster (perfect fit). They make fat cocking rod bumpers for autocockers. Just generally still handy. :)

I did the same to fix my 6pak

I put in a new reg seat, cleaned off the reg piston, replaced the o-ring and oiled it. I also swabbed out the crud that was built up inside the piston chamber with a q-tip and re-oiled again.


I cleaned off the reg and valve faces...I did find some gunk in there, probably gummy old oil.

I am finding that sometimes when I unscrew the reg the reg seat is hanging on the pin, not stuck in its seat.

After some cleaning it seems to be staying where it belongs now, but I wonder if that wasn't part of the problem. It's definitely in the right way, but I think there was enough gummy oil that it was sticking to the valve body.

I'm not re-using any reg seats, but I do hang onto all my old used o-rings and seats in a separate container...just an "in case of emergency" stash.

It definitely needed some cleaning back there. Tonight I'll probably de-grease the spring pack and velocity nut and put on the tri-flow grease instead...the old stuff looks a little mucky.
