aoc questions..possibly missing parts

[goose]

ok i have been tunning up a tribal bbt 2.0. it was having various problems with drop off and so forth...

everything is stock except the electronics are a v1e board and it has a cenetrflag guage in the asa adapter that the hpa threads into.

in the process of taking it apart to lube it and polish the ram and just general curiosity since i am new to tribals.

i found that behind the aoc cap is the aoc and plunger if i am not mistaken(feel free to correct me if i am wrong) it is the very first part you can pull out.

that particular piece has a hole through the center of it that is threaded as if a set screw or adjustment screw or something should be there but there is nothing there...

should there be something in that threaded hole?????

[warpedmephisto]

Nope, nothing should be in the hole. Thats what the air travels through from the AOC body. The threads are in it for use with an AOC plunger extractor which came in some of the tool kits. You can also use a rear grip frame screw to remove the plunger (same threads) if it gives you troubles.

Here is a pic of the AOC and valve disassembled.
That screw Warped is talking about is a 10-32 screw so if you have a spare you can use that to pull the plunger out.

Check out airsoldier.com as that site has a PDF Tribal Manual

We like using Dow 33 on those orings and lightweight oil like gold cup doesn't work well at all on Tribals. You have to take of the HPR, and ASA adpater to get to the part that adjusts the LP. Most cases it is set right, so make sure everything else is working right before you adjust it.

i used the ram to remove it ...it is the exact same thread as what goes into the hammer so i took the hammer off and threaded the ram into it and it pulled right out with no problems. that will not be an option though once i start putting thread sealer on things.

i do not like thin oil either and i am not extreamly fond of dow 33 either.

i find that ATF fluid works wonders.....ATF stands for automatic transmission fluid....dextron 3 with mercron to be specific....that is an old school trick i picked up....you should try it some time.

the problem with dow is it can cake up and make things gummy over time and if used in excess it's just not a good thing..... general gun oil can deteriorate parts overtime and breaks down rather quikly....

atf fluid on the other hand lasts a long time and the lubrisity of it is wonderful due to the fact it is specifically designed for a thin high viscosity application.

another option is a molybendum based lubricant as it also seals the minor scratches but should be used very sparingly.

just to make a point of how great i think atf is in markers......

i have a 99 autococker that i won in a tournament in the fall of 98..... at that time i tore the guts out and polished everything all nice and pretty then lubed it up good with atf fluid.

i have run hundreds of cases of paint though it in the last 6 plus years. ocasionally i will put a few drops of the atf in it as a preventative measure.

as of right now i have never had a single problem with that marker and it is my woodsball marker.. it has been used in rain, snow, sleet you name it...i play year round...puddles, mud, creeks nothing effect that thing...it truely is a tank in my opinion.

i have had numerous newer cockers that are nitro only and they had dow run through them and have ocasionally had to be stripped and cleaned out...

so that is my opinion of dow

[ME262]

atf will destroy the orings in the spool, make them gummy...

silicone oil mixed 50/50 with dow 55 works excellent..

[Edwin]

dow 55? Won't that make them swell?

[shiftycastro]

ive been using slick honey...... got it at the bicycle shop.....best money ive ever spent

[goose]

well i never owned a pnumatic so that was never an issue for me...always been blowbaack and cockers and it worked awsome...but you have a very valid point me262.

when and if i decide to tear into my tribal i will probably just go get some more dow and try that mix or maybee some slick honey i see it on ebay resonably priced from time to time

what is the difference between dow 33 and dow 55???

[warpedmephisto]

Dow33 is just a low temperature silicon-based grease. Dow55 is the same except it will actually swell the o-rings slightly to provide for a greater seal. Thats great for a static seal, but I wouldn't recommend it for dynamic seals.

[goose]

so basically 55 would not be good on a ram then??

[warpedmephisto]

Correct. You want to use a low viscosity, non-swelling lubricant in the ram and other dynamic seals in the marker.

[bakerboy4679]

I thought that they we're all Dinamic seals?
Which ones are static?

[goose]

the one in the noid and the one between the noid and body are probably what he is refering to as static.

those are not persay moving seals and once their in place a little swelling to make a good seal would probably be a good thing

[bakerboy4679]

ahh.. that makes sense.. and lol.. i slaughtered the word Dynamic in my last post..

[goose]

it aight..we aint no englesh majers here after all...der hey

sory dude just had to slam ya a bit but i am ten times worse...darn yuppers rubbin off on me

[warpedmephisto]

Any seal that is in motion when the marker cycles or that has a moving part slide accross it is a dynamic seal (ie: ram piston o-ring, internal ram body o-ring, solenoid spool seals, o-rings on the reg pistons, etc). Any o-ring that only makes a seal and does not encounter friction from moving parts is referred to as a dynamic seal. That would be like the o-rings on the valve, AOC body, solenoid gasket, ASA o-ring, etc.

I would try to stay away from Dow55 if at all possible on a Tribal and other electropneumatic markers - besides the Timmy because the o-rings in the ram need to swell a little bit to seal (too loose of a tolerance on the ram shaft and ram body). I have some new lubricant that I am experimenting with right now and shows signs of prooving itself superior to Dow33, but only more testing will tell.

[goose]

keep us posted on that warped cause i am not exactly fond of dow
but what do i know lol...

[bakerboy4679]

I use White Lithium Grease, made by LubriMatic. It seems to work very well. I would recomend it with the rest of great grease..

[goose]

ya know there is just something about a big purple hippo smaking its back side while somone is talking about white grease made by lubrimatic.

am i the only one finding this disturbing???

always good for a laugh :ROTF:

great way to start my day

[warpedmephisto]

I would stay away from White Lithium if you use co2 as it can turn to a gum like substance after it gets blasted by co2. Also, sometimes White Lithium can dry out and "cake up" after extended use. Although the 50/50 mix of White Lithium grease and Gold Cup oil never did me wrong when I used it back in the day.

I am letting Have Blue test out some of this lube and see what he thinks of it. To me it looks to be very promising stuff.

[goose]

sounds good warped

[ME262]

dow 55 doesnt swell the o-rings as much as most believe. it will swell buna orings more then other types.

plus its best not to use it "straight" i make a mix of silicone oils and dow 55 that i use exclusivly in all my guns, ive never had any problems.

also slick honey is petrolium based (from the smell alone you should be able to tell) it swells the spool orings quite a bit and will cause sticktion (heh dont know the words to use there)
i ran in to this yesterday in a freestyle running slick honey, after i had him clean it out and use the mixture i have his marker worked flawlessly all day.

[Edwin]

Yep I was also using Dow55, but I turned away from it because I was afraid it would mess with some of the orings that are not static.

Any suggestions on a good silicone oil or grease???
