[AT] Stuck JD B

[Ray Trimble]

I have a B with the engine stuck s/n 93620. I am researching how to go about freeing it.
It look like the way to go is to remove the block with the pistons with it. What bothers me
is the parts manual shows inserts bearing for the connecting rods, only shims. This leads
to fear this I may be dealing with a babbit bearing, which I know nothing about. First I don't know anyone 
who pours them and to get that done the crankshaft would have to be removed. I don't
want to do that, I remember posts yeard ago about the flywheel never being able to keep tight.

Can anyone inform me what I am faceting?

Thanks
Ray
