Airpak in a box

[Zaddict]

I just got my first m211! Someone took airpak apart and broke casing and all I think is in a box. I have been reading everyone's research and experiments and success. I was wondering if anyone might have a extra casting?
I'm new to antique military vehicles but it is a truck. I must say everyone on this site has been amazing and very helpful.
thanks

Look at the inside of the canister for pitting before you go any further. It needs to clean up very well. If all is good we should be able to provide some castings.
You can put a M35 air pack in it if you pull the check valve out of the master cylinder. It takes some plumbing

Hi henderson, could you please go into a bit more detail. When I got my XM211 running I think I may have used an M35 airpack, but I didn't modify the master cylinder. So far it seems to work ok, but it hasn't been used a lot.
Thanks!

If it has the check valve the brakes drag or won't release. Some newer masters seem to not have the check valve.

Glad to see you got on here with us! I will start digging for an airpak casting. Had a huge project going over the last 4 days and didn't get a chance to look for one for you. I will post pics later in my thread to validate my excuses. Ha!

It is my understanding that the check valve in the G749 is in the airpak and not in the master cylinder. The M35 is opposite with the check valve being in the master cylinder and not in the airpak. I think this is why Bob Kettler said problems would occur if you use the wrong master cylinder. I think the master cylinder is interchangeable simply with the removal or addition of the check valve depending on your application. Each of us will have to make this decision for themselves.

I spoke with Memphis Equipment last year and they told me that they have been using M35 airpaks on G749s with slight modification to the plumbing. I didn't get any more details from them since I was able to rebuild my M135 airpak. I did make sure there was no check valve in my new master cylinder.

I spoke with Tom from Alfa heaven last summer. Same story.

It doesn't look pitted but I will clean up top.
