Here's what happens when you overtorque drain plugs...

After its welded I would screw the plug in with the O ring before adding fluid apply some RTV, let it set up, and it should seal and keep the plug from un screwing, I would not over tighten the plug.

 

Hats off to my Welder Tim. Spent quite a while under there sewing her up, and managed to salvage all function of the drain plug. Globbed some pipe dope on the plug and snugged it in there, drove around for a while and problem resolved. Thanks for the advice gentlemen.

 

no pics of the repair?

 

Resurrecting this old thread as I just did this a few days ago. Was cold outside as I was changing fluids in diffs, transfer case and transmission. Was hurrying and using a breaker bar to tighten.... I ooga boogad waay too hard till I got a nice click.



I also noticed that I had 2 crush washers on when I removed the drain plug.

I just drained the transmission, cleaned the outside with a flathead screwdriver, brake cleaner and the rag, and then put JB Weld on it. I'll try to put a picture of the repair later if all works out. (Fingers crossed it holds and I don't have to weld anything).

 

"Breaker bar" = "break things".

 

If you have a great welder then it can be done

 

When I doubled my 88’ Runner, I noticed the it was leaking from the fill hole and had a pretty good sized crack.

I cleaned it up and JB welded it, and filed it smooth. That was 4 years ago and it hasn’t leaked a drop.

I didn’t get any good pics.

 

Here’s mine after the JB Weld cured. I sanded it smooth and refilled my transmission. Haven’t checked yet to see how it’s holding.

 

Another thing you can possibly try in welding supply stores they sell a paste that I've used the past its a like playdoh when it hardens into medal and you grind it it excelent

 

When you check it, take a look at the other crack too (about 3:30 on your image).

 

No obvious leaking through any of those cracks yet. A small amount of wetting under the crush washer (now reused, but at the correct torque spec). It has been run and sitting in place for a day now. Plan at this moment in time is once it’s registered, to take it to a wash, clean the transmission better, then JB weld any additional cracking that I find. There were a few others as well. Will be watching the market to see if I can find a new replacement bell housing as I need to do a throwout bearing and will do a full maintenance (bearings, clutch plate, flywheel, seals).
