Henry Ford would have had enough sense to make the N's where the oil pan could be removed without have to take the front end off. Dorkiest engineering ever! Were the Model T's made like that too? On the fresh rebuild, the oil pump won't hold a prime. Oil pressure drops too. I am pulling it to see if TOH will take a look at it and see what the problem is... Could be I did not replace the pick up tube for a fresh surface for the gears to have. I think the large gear is cocked ever so slightly and I had to dremel down a couple of teeth on the smaller gear so it would not hit on the side of the body. Some things just pizzzz me off! Good thing I bought a new Kubota to take up the slack around here. I think they are made in a plant in Georgia so they are Somewhat an "American" product with jobs for American!
