If you care to search awhile back there will be detailed posts of my recently (last January) rebuilt 8N sidemount engine. I put new gears in the oil pump body/new sleeves/pistons/had the crank turned/new valves etc. Just a standard rebuild job to last a long time. Only problem was low/no oil pressure at startup. It doesn't take long to tank the bearings/crank shaft either. Here are some pics. Just *#@&*&^
I did send the oil pump to TOH after I figured out there was not enough oil pressure to amount to a hill of beans. He put new gears in it and sent it back. I installed it and still had low/no oil pressure. By then the bearings/crank was already messed up. I guess I will pull the engine and see about getting a used crank. This one is .060 rods/.040 mains so it is now a boat anchor. Maybe this could be polished out, I can barely catch a finger nail on the one crank main? I don't know at this point. Glad I got a new Kubota back in the spring....lol I would have been up to my ears in grass/weeds by now. :shock:
