Mounting a cat blade from a 7U onto a 7J and was wondering (for welding purposes) what the frame rails and the blade mounts (that bolt to the frame)are made of? There are a few cracks I'd like to weld. Need to do a grind test tomorrow but figured someone might know. Looks and sounds like cast steel but that might just be me being optimistic.
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄
