Cylinder Lubrication

[m_kernohan]

I just finnished building a new v2 gearbox for a tm mp5. I used silicone oil to lubricate the new cylinder and o-ring. Is this oil going to dryout? Its firing extremly well right now, strong and a high rof. Should i dissasmble it and use the silicone grease in the cyclinder?

Thanks

List the name of the product you used. Then check the label for petroleum distillates, if it lists them, clean and get airsoft silicone.

He just said SILICON oil not unknown oil. I would use a silly grease though. You'll quickly blow out most of the oil through the nozzle and be left with a very dry cylinder.

No, you should be using very light oil in the cylinder.

Well really, as long as you've got some lubricant in there, you'll be fine. Just not too thick and not too much, or too little. Enough to provide smooth movement of the piston.

thanks for the info. How often should i have to re lube the cylinder, considering i used silicone oil instead of grease. If i can use it for a bit and then change to grease after, i woulkd be happy because i just got it all together and working well and would rather not take it apart right away. If the worse that will happen is i should change the oring im not to worried for a bit.

You should only have to lube it once, and it will be good for years.

Relube if you change piston heads, cylinders, etc.

that's just it. I find when i use just oil the piston head o ring gets dry after every thousand rounds or so. Grease has staying power and when worked in it turns into a thick oil. Just don't use too much. Guarder, tm, systema all manufacture a cylinder grease. it's thinner than gear grease. You could also mix oil into the grease to produce a "silly sludge". There's a recent thread about lubing a mechbox and it talks about greasing the cylinder as well. Read up and get ideas.

Best stuff ever.

I've had some issues in the past with ported piston heads giving varying velocities, sometimes they inflate properly, other times they don't. And this can vary from shot to shot as well. I've always used silicon grease, or lithium grease, but at some point someone on here said they only ever used silicon oil, a light wipe on the O-ring and cylinder, and never had those problems.......... so I tried it for a few remaining guns after I got out of the gun tech business, never saw that problem again, worked perfectly. So I'm of mixed opinion about using grease in there as far as ported piston heads go.

If you use too much grease in the clinder it can clog up the ports and cause the O-ring to expand and contract poorly.

What I do is I remove the O-ring and put a thin film of grease on my finger and work it into the O-ring...

Man.. All these little tips and tricks have me all excited to start that tech blog I've been thinking of doing..

I do the same and its worked just fine all these years.

You should start a blog on that subject. I would guess I've seen the same YouTube videos you have of people showing how to lube gearboxes and the end results is they don't show the complete process. No where have I seen them show that the teeth of the gear need a small amount of lube or the piston teeth or anything about lubing the tracks for the tappet plate of piston track, etc. And while you’re at it a good explanation on how all version 2 and 3 gear boxes are not equal would also be a worthy cause..
