D2 oilpan

Last night, pulled the leaf spring and oilpan off of my D2 3J. Found that the pan is cracked in the area where the leaf spring rests. Is it right that the spring rides right against the pan?? The crack explains why the springs were just a big bunch of caked oil and dirt!!
My reason for doing this, the engine is seized. I am hoping I can get the liners and pistons out and then salvage the pistons. Cat says I can still get liners.

Yes, that is a fairly common problem on both the D2's and D4's that have the spring mounted to the engine/pan. Weld repairs have mixed success depending on how thin and how much damage.

Pistons, sleeves and rings are not a problem to obtain...it's the bearings that have become near impossible or extremely pricey if you find them.

Thanks, I was able to get 2 pistons out. They look quite good considering. The bearing shells looked really good. The crank has some wear but is nice and smooth although I haven't measured anything yet. Plan to run a hone through the liners and see what happens.
