I used a bench grinder with a nylon wheel on everything but the air canister. Used an angle grinder with a wire wheel on that.

Would you post up some pictures if it and it's internals when you get a chance?

Cleaning up airpak parts for the rebuild. This is the worst part for me. Things are going nicely though.

I've never seen one of those before. Cool!

I like the looks of those trucks. Looking forward to seeing what you do with it!

That is the line I was talking about. I missed that page in my search for a diagram of all those lines running all over. The hose that hooks to it is next in line to get a new one. I am also in the middle of replacing the upper and lower radiator hoses since they were still the old military ones.

I have come up with enough parts to make at least one good airpak. Everything needs cleaned up and then I'll start the rebuild. The parts I have scrounged appear to be pristine on the inside. All of the coolant and oil hoses for the air compressor have been replaced with new and little by...

Looking real good! Did your master cylinder come in yet?

What are you using to do the sanding?

I tore down a G749 airpak today so I can start preparing for a rebuild. It was not as difficult as I thought it would be. Hopefully I can find enough parts that are not pitted to make one good airpak. I still plan to tear down an M54/M809 airpak to find out the difference between the two. I...

As of last weekend, still no leaks. I decided to put a new master cylinder on and rebuild the airpak. We'll see how the wheels cylinders hold up after all that is done.

Good looking truck! Ugly can be fixed easily. Everything looks straight from what I can see. You have a lot to work with there. What year is the truck and can you see what the hood number is?

Oh man. That is terrible. What does FedEx have to say?

I don't know for sure but I have heard they are Timken axles.

Master Cylinder rebuild kit added.

My new master cylinder came in today and I am very happy with what I see. I ended up ordering Raybestos MC2842. I chose that because some of the M35 master cylinders I saw did not have the holes on the side drilled and tapped. We need the top hole, since part of our brake pedal linkage hooks up...

Digital copies are nice but sometimes having a paper copy right by you when you work is the way to go. Ebay has some reasonably priced. Portrayal Press isn't too bad either.

Some of the pictures are on post #451 for when you need them. http://www.steelsoldiers.com/showthread.php?52255-G749-preservation/page46 Kinda threw you under the bus there M1010plowboy.....knew you could handle it though.

Welcome to the forum! I would highly recommend ordering a copy of TM 9-8024. It will be a huge help to you as it was and is to me as I have been learning and working on these trucks. The carburetor will probably need a rebuild. The fuel pump can freeze up if left in old fuel. I'd highly...

My best guess is someone used an M35 master. It all appears to be original Wagner-Lockheed. Everything is identical to the other master I pulled off of a parts truck that came direct from the Army and has not been modified in any way. Just no check valve in that one.
