repairing leak in oil bowl on an air cleaner

It seems like every tractor I work on the oil bowl on the air cleaner has rust holes in the bottom Many bowls I look at in the salvage yards also are rusted through.
Could you share with me any repair procedures you use to correct this problem ?
Thank you in advance. This site is a gold mine of ideas.
 
farmerhr,Like Shaun I would braze it up,but for someone without a oxy/acetylene torch. Get you some JB Weld and cover the inside bottom with it.

Nothing wrong with brazing, but no reason it couldn't be soldered with 50/50 solder or some modern plumbing solder that contains a little silver. (Harder/tougher.)

NO oxy-acet torch needed, and no chance of burn-through or warping from a little too much heat.

If the damaged area is large a sheet copper or brass patch could be soldered over the hole.

Let me guess, most didn't leak oil until you cleaned it real well. Unfortunately this is a sign of neglected maintenance. Way too long between cleanings, with dirt and moisture in the cup. Though you probably realize that.

My solutiom - R&R,

then regular maintenance.
 
farmerhr, just curious, what part of the country are in located in? I'm in the Pacific Northwest and have three tractors ranging from 1944 to 1954 and none of the oil bowls leak or are even have rust spots in them.

You are on the dry side of the great pacific northwest!! that said I have three machines with oil bath airclearners and also do not have any problems, but then I do service them regularly. I do not leave machiness out in the rain and DO NOT run them in the rain, on the wet side of the State we do get a lot of condensation in and on everything even when parked in a tractor shed. once a year drop the bowl and clean and replace oil.
 
Thank you for your thoughtful suggestions. We are located in southeastern Michigan (70 miles north west of Detroit).
I agree with comments about regular changing. Most of theses machines have set for a good spell.
Yes, the leaks due usually show up after a good cleaning. Surprising to me how the cups hold oil without leaking until cleaned for painting etc. Once again thank you for your help.
 
Around 2002 I bought my first 8-N. After cleaning the bowl I found several small pin holes...after observing the clean oil leaking onto the floor. I used acid flux and soft solder (same as for copper tubing etc.) to repair each hole. To me brazing is over kill and you risk doing more damage due to the heating required. I would think JB Weld would be a good option if your solder skills are not up to date.
 
i had good luck with a wire welder, basically a tack weld, then grind down flat to match the surrounding metal.
