I have had experience with cracks on 1926 ALF fire truck engine cylinder jugs, in an area near a valve seat, and water jackets. It was stitch weld repaired, a very good but tedious job. No heat, or trying to weld old impurer metal castings. I have also used J B Weld, which is a 2 part epoxy mix on the same castings with success. I had a crack in the oil pan on a D-2, preheating and welding never worked. Good luck, I hate cracks in cast iron.
Dyke stop leak for minor leaks.
You have a wonderful day. Best wishes. Deas Plant.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
