The brakes on the middle axle are done. Following hendersond's lead, some gasket maker was put in around the cork seal. On to the rear axle......

I imagine the days of printed parts is not too far off. Here is a teaser of what I am working on for the G749's. Getting enough free time on the machine to make several is the hard part right now. If I can't get many made, at least I will have the programs to do so later on.

That looks good!! What else are you going to start making?

Did you ever get anything figured out with your manifold topo?

The work continues on the middle axle brakes. All the parts are in, things are cleaned up, primed, greased and ready to go back together. Do any of you use anything in addition to the cork seal that goes in the slot? Use anything different? I have the cork seals but didn't know if I should...

Thank you guys. If I wanted to trade it toward M135 parts since I don't have a Gama Goat, what would be a fair value? I really don't need it, but don't want to trash it since someone may need it sometime.

Does anyone know if this is a seat for a Gama Goat? It was sitting on the back of an M818 my brother bought. I have never seen a Gama Goat in person and was trying to look at pictures of them online to figure it out, but I just can't tell. It does appear to be a military seat of some sort. Any...

Where are you getting your new cork seals for the slot from or are you going back with something different?

Parts list updated with 1-3/8 bore wheel cylinder and wheel cylinder rebuild kit info. The 1-3/8 wheel cylinder is a replacement for the early 1-1/4 bore wheel cylinders that are not readily available anymore.

I will probably need 8 brake shoes, but won't know for sure until I tear down the rear axle. There is a place called Weldon Truck Parts in Tulsa that has a brake relining facility in Oklahoma City. They sent in the 4 shoes I had to see if they can reline them. Still waiting to hear back from...

What were their prices like?

I did a lot of looking online and at a truck parts store today and there are no 1-1/4 cylinders to be had that will fit. I will have to replace all of them with 15306. If I need to get rid of them, you are first in line. Hopefully this truck parts store can reline my brake shoes. Should know...

Did you get a new master cylinder or a rebuild kit? Where did you get what you got?

I found this thread. It was late last night and I guess I overlooked it. http://www.steelsoldiers.com/showthread.php?79598-GMC-wheel-cylinder-parts Plowboy...are you using the Wagner 15306 that you posted a picture of? Those are what I ordered. If I am not mistaken, Nattileather used the...

I have started going through the brakes on my middle axle and now have a question. Three of the four wheel cylinders are bad and the brakes need relined. I ordered four wheel cylinders, part #WC15306, which is a 1-3/8 bore. The original wheel cylinders on the truck are all 1-1/4 bore. When I did...

That is a neat truck. Keep up the good work!! This reminds me of everything I have been doing to my 1952 M135. It is really rewarding when things are working right.

Have you checked with these guys? I can find several places online that sell Hydramatic parts, but I am not sure what kit we need. http://www.autotran.us/index.html Hopefully we can find a rebuild kit that will work. I have one or two of these transmissions that may need rebuilt too. I have...

I got some clarification from Oldfart last night. These pics are of the G749(left) and M54/M800(right) pistons next to each other. The M54 piston internals are a larger diameter but the externals are the same diameter. Here is what Oldfart told me: "It is my understanding from Gun Freak that...

Am I understanding right that all we need out of the 5 ton airpak is this??? I pulled this out of an 800 series airpak. That will allow us to use the 5 ton rebuild kit? Will all the seals we need be in that kit?

I agree. There is so much good information in that Preventative Maintenance Monthly for the G749!!
