Small hole in AC-B axle housing. Options?

ALLIS FOREVER · May 31, 2020

Hey everyone. Long time follower but just joined.
I have a question regarding my Allis Chalmers Model B. Today after power washing noticed a nice sized hole on the right side axle housing. It was a little damn with gear oil so I stopped using it and started coming up with solutions.

I will attach pics.

Should I weld some metal plate, use jb weld stick steel or replace the right whole housing. It’s a 1939 so I think it’s got the smooth housing versus later models but not sure. It’s not a restoration piece but I do use it and give my nephews rides around the property.

I will be painting her this winter and cleaning up some metal.

Also any idea how this happened as I have no idea and never seen a hole in any of my housings tractors or classic cars. I noticed small clank on that side today but the tire has large bulge in it and is loaded with antifreezes also. Runs fine and still descent amount of fluid in it.

Thanks
Tory

There is supposed to be a hole on the bottom and at the top front for the brake return spring.

Hey Ted
Here are pics it doesn’t seem like a brake hole as I saw those holes. This is uneven and doesn’t look factory. Plus it was leaking gear oil

Some reason my
Photos aren’t coming in

I figured pics out. Here is the odd ball
Hole. Its a shame
If I have to replace the entire right side housing. Thinking maybe jb weld steel putty or flux weld my own metal
Piece on. No idea what caused this. Runs fine but definitely lower on fluid.

I'd just clean it up good and JB Weld it. Must have broken a tooth at some point.

I’d guess you’ve had a piece of bearing or gear tooth fall on the big gear from above and there wasn’t clearance between it and the case wall

I would pull the pan off the bottom of the housing and see if there are any pieces in there before patching it. You can also jack it up and rotate the wheel to check the gear while the pan is off.

Thansk for the replies everyone. I’ll drop the pan see if the tooth is
still there that makes the most sense. I’ll brake clean it and then jb
weld it.

I knew I couldn’t not have rusted.

I hope you don't find anything wrong when you pull the pan. As for patching, you could use JB weld if you clean it really well, or a small metal patch held on with a few small (maybe no. 8 or 10 screws) and sealed with silicone gasket maker. When putting the pans back on I use two "pilot" studs, bolts with the heads cut off about 2" long to line the pan up with the bolt holes. After you have a couple of the screws back in you can remove the pilot studs. I also put oil in the pan before installing it, if you fill to just a little below the filler plug it will be OK. And over filling a little won't hurt. This way I am not having to try and pour or inject oil later, just seems easier to add the oil, then carefully lift into position.

Thanks Tom
Hoping what ever it was Came our or is sitting on the bottom of the pan. The stud idea is great I will do that for sure.

Do you just use rtv or gasket maker. I don’t have any gaskets in stock and heard of people using rtv

I would not use RTV, you need to buy or make a gasket. Glue the gasket to the pan with contact cement, then install it with a gasket sealer.
