Okay Gents, Time to Fess up as we say in Texas. I found my problem and it was operator era. Yeah I made a mistake. One of many in my 76 years.
The main bearing holders can be put in backwards and as luck would have it that's what i did. Oil was not building pressure as it was flowing with no resistance at all. I know it is hard to visualize but that is my problem. It took me about 45 minutes to split tractor and pull engine. I thought I could push the pistons up far enough to get the crankshaft out without pulling head and knocking pistons out but once again as luck would have it (no luck). Had to remove head and pistons to get crankshaft out. Going to call Fredricks Monday morning and get another set of the two center main bearings. It will be late next week before I get parts and a couple days to get back together. I will let you know how it turned out. As a side note, when I put the main bearing holders in the first time I studied the parts diagram to try and get it right. The diagram was a little confusing and then Yanmar stamps a F on the main bearing housing which I thought stood for front but low and behold the F faces the Rear. O well not trying to place blame elsewhere. It was this Dummie's mistake, and their you have it. I appreciate all the support I got from this group. Thanks again...
