hello all,
          Just a little tip for the new guys. I am new myself and have discovered a few things that may help a new guy but may be rather remedial to the veteran atlm'ers, therefore I put it here for the new guys.. When welding up the rear axle, first clean the gears and case very well. All the slag and junk from welding will stick in this old greasy mess. I weld the axle while it is laying in the case to keep it straight. Weld the spider gears( the little ones on the end of the axle) to the ring gear(big one). After welding, spin the axle to make sure nothing(like too much weld) is hitting the case. If so clean it off with a grinder. Clean everything again and put it back together with fresh grease.
   Attention:The brass bushings that are on the ends of the shafts that the gears are on have little tits and grooves in the case that keep the bushings from spinning in the case( I did not know that till today). It will lock up and bust the case if these are not lined up(I KNOW).
     Every transaxle I have taken apart has had at least one bolt under the input shaft pully. If you cannot get this pulley off, drill a hole in the pully above the bolt to get a socket on the bolt.
     After removing pulleys, hubs, etc. always use "anti sieze compound" on the shafts when reinstalling them,(ask at your local parts house).
     I hope these tips may help somebody along the line. If not, sorry I took up this space.                                                  Tom

that is good info, I especially like the drilling the hole in the pulley part, good idea (I use a automotive pulley puller, this usually ruins most sheet steel pulleys)

I will have to take pictures of one I have already welded up, as I have welded them all up already, and try to figure out the posting of pictures. I will study into it, I saw it somewhere around here. Hope to do so soon.

Here's a walkthrough on how to use it. It's for my other site, but it's the same picture upload script.

Youve gotten through the hardest part.  Now in your photobucket album under the picture there should be a checkbox.  check it.  then scroll down to the bottom of the page where it says "generate HTML code" click that.  On the next page click in the box where it says clickable thumbnails for message boards"  copy whats in the box then paste it on here.  And that should do it.

I did that, did a fairly nice write-up I thought and hit post.   The whole thing is gone now. I can,t find it. Should I try it again or do you think it is here somewhere?

Here they are, of course they are backwards  eyebrow, just start at the bottom and go up. If anybody has any questions let me know. My test picture above is of the inside of a typical hydro.




The two holes drilled in this top pulley are for an automotive steering wheel type puller (Not the claw/arm type). They don't distort the pulley. I got tired of messing with it and just drilled one of the holes bigger so I could get a socket on the bolt underneath through the pulley.


Slots in the casing.

"Tits" on the bushings, must aligh with slits on case when reassembling.



The next three pictures show weld points. Be sure to spin axle to check for binding from excess weld.Grind excess weld for clearance.



All clean.



Use a scraper and degreaser to get out what you can.

These Two pics are of a freshly opened up transaxle.

Now you got um!!  I have a foote transaxle that i want to lock and this helps me out.  but just to double check- your welding the 2 spider gears that are on the axle- you weld the one to the drive gear and the other to the cage?  And it looks like those are stick welder beads, what rod are you using?  Will 6011 work on electrode negative?

Correct on welding the spiders to the cage and ring gear.   My welder is a lincoln flux core welder.     .035" wire. I would say any type of welder you are comfy with will work. The pieces to be welded are very thick. I don't think you will hurt them.    The last one I welded was a foote. The case was tight around the diff which caused me to have to grind away some of my weld for clearance. Just remember to let everything cool and spin it while it is laying in the case. If there is any problem you will see it.
