After changing the oil in the dd on my 06 700cf I noticed a small amount of fluid on floor the next day. After closer inspection the dd case has a small crack at the oil drain plug. It's about 1/4" - 1/2" long. Does any body know if this can be fixed with something like JB weld or do I need a new case half? Going west in 10 days need input ASAP.

Thanks,

I'm sure you could use jb weld if you cleaned it up good and sanded the area so it would stick well. But i would say having it welded or replaced would be the better way to go. The jb weld could be used as a temporary fix, just keep an eye on it to make sure it doesn't get bigger or leaks more and runs out of fluid.

Looking at the pic. I would get a small drill bit, and a center punch.

Punch the end of the crack lightly. Drill it about an 1/8" into the metal to stop the crack from spreading.

If you have a Dremel, make a little, I mean VERY little "trench" in the crack. Then use your JB Weld at a temp over 60ºF. Be sure to Brake Clean (the GOOD KIND) or Acetone the area.

My Dad was a Die Maker for 39 years, and my Grandpa 20 years before him, and my brother now. I have picked up a few things over the years. I think if you follow my directions above you will be okay for the rest of the season. I would also put some teflon tape on the drain plug for added measure.

Now, a good welder could TIG it while it's assembled. If you can get a pic of it, a real good fab guy and weld it.
