Still couldn't get the engine loose after sitting for 3 weeks with solvent in it so I pulled the engine and took it apart. Did salvage one sleeve and piston, but one was already broke from some previous repair. So now I'll have to try to find one used sleeve and piston or maybe I'll just decide to rebuild it completely. Hate to spend that much money tho. Also pulled the clutch and found that needs replacing, so it will be another trip to the clutch doctor for me too. The good news is I figured out how to turn the track chain bushings so I won't need a new track chain. Will need 4 rollers tho. Sorry no pics of todays progress.

On another note, I got the bearings out and at least the mains look like originals and are in good shape. The numbers on them are d.a.r 1 58 vt 3204. There is no indication ofbstandard or not but I would guess the 1 58 is the date?

The rod gearings also have no indication of standard or not. The number on them is 3636B002N.

Are these bearings standard?
 
I have always found over size brgs to have the size stamped on the back of liner. The crank should be stamped also. My guess is you have std brgs. Rod.
 

Jon,

Your vt 3204 is a DAB bearing and is std.

The other I have not found the cross reference yet.

Case p/n's VT3204 crosses to G11018 which is the standard center main bearing liner used in the VA 124 cid and 300/300B 148 cid engines. The standard front bearing liner is p/n G11012 and the rear standard bearing liner is p/n G11036. I haven't been able to find the original VT p/n's for the front and rear main bearing liners.

Just wondering, is VT3204 on all 3 of the main bearing liners? That would make it a p/n for a set of liners? It just doesn't seem reasonable to put the same p/n on 3 different liners.

If your engine the 148 cid that is used in the 300 series, the standard conn rod bearing liners are p/n VT3390 sub to G11141.
