Dad wants to see if we can get the main bearings adjusted instead of replacing the engine (again). When I was taking shims out of the connecting rods, I'm pretty sure there looked to be at least 3 shims in the main bearings. At least that's what my memory says. I've since lost my shop manual, do the main bearings adjust the same as the connecting rods? Do they all just unbolt from bottom? Is the oil pump in the way of the middle bearing? It seems like that was a nuisance when I did the connecting rods. Then I guess we'll have to find a machine shop(previous guy out of business)for the head and see what that's all about. Thanks for your help, -dave
