I haven't got a manual for it yet, but I was wondering if anyone had the specs for the thickness of the steering clutch pack. Also did the fifty gas and diesel use the same rear end. Any input is welcome. Thanks!!! Still looking for a jug for it. Tried omnicrop and Jim Zimmerman with no leads. Jim says I may have to get it dry sleeved. Also the outside of the jug is cracked. Tried nickel rod but tiny cracks appear. Any ideas on this one? Thanks!!

hello Jbayer,i can help with clutch pack thickness ,bruce oz

Jbayer,
Sorry i don't have a jug either. did you preheat when you welded? I have had good luck on cast if you weld an inch and then immediatly hit it with a needle gun and stress relieve it. I will keep my eyes out for fifty parts for you!

Find the ends of the crack and drill a 1/8" or so hole just beyond where the crack starts. .this will keep the crack from "running" further. If you don't do this, there's a good chance the crack will continue to spread specially in something that the temp will vary.

Most times I'll use Ni Rod 66 but when there's a "problem" weld, I'll grind out what I've welded and switch to the Ni Rod 99. Preheat to 450 F or so, short welds, peening after each inch long weld and bury the part in lime or ashes works well. Let it cool totally. .for a day or so before digging the part out.

Back "in the day" cast iron used to be gas welded with actual cast iron rod. This meant the part was heated to a dull red then fusion welded. After welding it was buried in again, either lime or ashes and left for several days depending on how big it was.

Thanks for the info and for keeping an eye out for parts. Ol grump, on that 1/8in hole, do you weld that up also. I have some sand, I was once told to leave cast in it to cool slowly. I will go to the welding store and get some of those rods. Just know the ones I have are nickel but not sure about the 66 and 99. Thanks again. One more question, is brazing a solution here. I have brazed other cast but never tried on something like this. Just wonder if the brass would flex and not crack.

I will probably draw fire for saying this but....those water jacket castings are very thin and proper welding may not be possible. After drilling and veeing if you fill with JB Weld it will work. I repaired many freeze cracks with it with good success. I let it set up for a week between coats in hot weather and when I went to grind it I could not tell the difference between the JB and the cast.

I have used JB weld on an old combine block and it is still holding. I was a little concerned on this one because of the vibration of a cat running. Also the heat close to the exhaust. Have you used the J word on a cat before?
