Case 580sl cracked frame.

There are several cracks in the frame where the Front engine support is attached to the frame. The support has pushed into the frame on both sides at some point and then welded as it was. Not very good welds either, about my skill level. I've only had the machine a couple weeks and didn't notice this until I pulled the hydraulic pump off.

Any ideas on what caused it? The front motor mounts were deteriorated and in upside down. I can get some welds on the cracks and on the support,...
