backhoe subframe cracking

[CADplans]

Go to the local CAT dealer,,
find a similar looking joint on a piece of CAT equipment.

The CAT will have the joint properly fish plated, just copy it.

Thanks for all the help I will pass on to my buddy about the fish plateing.

Please post photos of its repairs. If your buddy does it right, it shouldn't break there again. Seems they didn't build that section right it the first place.

Surprise, surprise....it cracked where they welded cross ways where all the force pulls on the steel. Weld on the length...not across it.
