Hi all, I had an arm break on my grader. I'm wondering if anyone has a parts machine? It's the arm that attaches to the gear box that lowers one side of blade. I caught a big rock just under the surface and it broke in half at both keyway's. Here's a picture of part. It looks to be all cast so I don't think a weld/strap would stand a chance. Thanks for any help. Thomas https://www.allischalmers.com/forum/uploads/25809/20250811_160549.jpg" rel="nofollow - uploads/25809/20250811_160549.jpg

Cast iron would be brittle and break... It MIGHT be cast steel... and could be welded, if you dont find a replacement.. ------------- Like them all, but love the "B"s. |

Sandblast - Wire brush till clean and wash with soap/ water.. or gasoline...i would bevel the crack on the OUTSIDE so it goes to a thin lip or edge on the ID... clamp it around a brass or aluminum tube so it is ROUND and right size.. or you can finish grind the inside with a die grinder later if you dont have a tube.... Preheat it with a propane or gas torch IN THE WELD AREA up to 200 degrees or better.. The preheat is good and it will drive off any oil or residue... I always use 7018 stick rod on DC when i weld cast steel... Your milage may vary.
