I have just finished a rebuild on my 1952 8n engine. Sleeves, rings, pistons... the whole works including a new crankshaft and bearings. I assembled using assembly lube and torqued to spec after checking bearing clearance with a plastigauge. Everything is in spec for torque and clearance. The engine was hard to turn over by hand/ratchet but I could get it to turn over. The last thing I did while it was on the stand was to give it a try and it was tight, but moving. I installed the flywheel and clutch and mated it to the tractor. Now the starter wont even turn it over. Fully charged battery, etc. My question is, could I have installed the flywheel incorrectly causing it to bind and prevent the starter from being able to turn the engine over? The spark plugs are removed during all of this. I tried rocking the tractor back and forth and having my wife dump the clutch just to see if I can get the engine to move but it wont. Any ideas on what could be wrong?
