cracked housing

kendak · Mar 25, 2010

after replacing the axle seals & cleaning the bottom of the axle hausing of dirt ,oil & various pieces of guke in my 37 JD "A" I replaced the rear cover & filled with 140wt oil...in about a week all oil had leaked out on the floor of my shop...after careful inspection I found several small cracks in the bottom of housing...I believe that I can clean these with solvent & then heat with a torch to burn out any left over residue....what liquid or paste can I fill the bottom with that will harden & stop any leaks ?...could probably put about an inch or more in the bottom without getting into anything.....wasn't leaking before repair so I assume dirt & guke had sealed cracks..tractor is not used just part of the family....have another housing but hate to have to change it out....thanks ...Kent

I think Araldite will stick to steel.

I saw an add several years ago for stuff called Belzona molecular that was supposed to be good for repairing all kinds of stuff. Maybe JB weld would also work but use the regular JB weld and not the JB quick. Make sure to let it dry for at least a day. Clean it real good and remove the paint. Use can wet your finger with a cup of water to smooth it out if you want. I used JB weld to successfully repair a hyd. oil cooler. Dave

One time I was restoring an old Caterpillar
and water froze and cracked the bottom of a
final drive. I cleaned it out and heated with
a torch to clean out cracks. Melted some scrap
lead between 1/4 to 3/8 inch thick. It has held
for over 30 years.

If you look in a Jegs or Summitt Racing catalog they have whats called block filler and race engine builders sometimes use it to fill the water jackets in a engine to make it one solid block that can withstand much more horsepower. I believe it's an epoxy that you pour in the bottom and it hardens in a thick layer. I think you can buy it in gallon jugs or maybe even 5 gallon cans. Not really that expensive if I remember right.

Belzona will work, the area has to be completely free of dirt & grease tho. Belzona is a little more expensive but better than most others in my opinion, it can be machined & drilled & tapped. Just my thoughts, Keith

J-B Weld or Devcon. About 12 years ago while combining Fescue Seed with one of Dad's C-II Gleaner. I hit a BIG rock in a field with the transmission. Later we lost a U-Joint on the un-loading auger. While waiting for the new U-Joint the machine was setting on a concrete pad which let us discover the oil leak in the transmission from a crack caused by hitting the rock. We drained the trans, cleaned it well with spray carb. cleaner. Covered the crack with J-B Weld and covered the J-B Weld with Duct Tape to hold the J-B Weld in place until it cured. The J-B it still there and there are no oil leaks. The combine was used this last year to cut Fescue Seed. I do not know why my Brother wanted to cut the seed as the price, in my opinion, would not cover operating costs.
