Air Pack question.

[swindad2]

Progress update:

The machine shop I took the air pack to has been backlogged with work from local factories (guess I am low priority). I decided to go pick it up today and put it together myself. I think I might be screwed though. After inspecting the cylinder they honed, I am afraid it is pitted too badly to use. The other one is even worse, so I didn't even attempt to clean it up. You can see in the picture where the water pooled on the bottom side. Has anyone installed one in this shape? It all feels smooth, but you can definitely feel slight indentations where the rust is. I assume the bore needs to be perfectly smooth? I really am not prepared to spend $500 on a new one. The deuce would be my doghouse.

Rustystud has a source to have them relined.

The only problem is the shop wants over $100.00 to bore it out, and will not guarantee it will remove all pits. I'm not sure how much can be taken off before you put the air-can in danger of splitting open from use. The other thing was they could put a stainless steel liner in it, but that was some serious money ! I could almost buy a rebuilt unit for that kind of money . I'm keeping all my old cans just in case the market drys up and I can no longer get parts. Then I'll have them machined, but until then Ill just keep getting my parts from fellow members and the want adds .

Yes the bore should be completely smooth. If it is not you run the risk of damage to the seal . I would try asking fellow members if they have a old one they would sell to you. I got a good one from peashooter and gimpyrobb . I have since gone to the short style air-pac for my M35A2C , but I'm keeping my long style ones just in case . I got a short style one from Warthog . He is a great guy to buy from. A good Honest seller ! If something is wrong he'll make it right.
