I have a 49 Case SC, I bought it from an online auction a couple years ago. I didn't get a chance to inspect it before I won the auction at $770. The day I went to pick it up it wouldn't start so I had it towed to the shop near-by where I work. Upon looking at the fuel tank and line it was completely full of rust. After checking out a few home remedies to clean the tank and putting in a new sediment bulb assembly I was able to get it running. I had used it on the gravel lot at work and when I finished I noticed oil leaking out of the head gasket, so back in the shop it went to figure out that issue. When I took the valve cover and head off the pistons, rocker arms and valves were covered in burned oil. The valves and seats were in rough shape, in need of grinding and re-seating. I didn't stop there and took out the pistons to check the rings, one of the sets was completely seized in the grooves so I ordered a complete overhaul kit with rings and the necessary gaskets. When I got the head back with the valves cleaned and properly seated and putting the new rings on the pistons I began putting things back together. This is where things begin to get confusing to a greenhorn mechanic like me. I put the pistons back in the block and put them in their cylinder holes according to their number stamped on the connecting rod and on the piston head, tightening them to their prescribed torque specs from the Case manual I ordered. The issue is the crankshaft is difficult to turnover acting as if something is holding it from cranking like it should with a brand new battery. Even using the hand crank I struggle to turn it over. My uncle says you should be able to turn it over by hand. So my question is what would be possible issues that are resulting in a hard to crank crankshaft? Aside from the worst case being the shaft is bent, what are other possibilities? Sorry for such a long story to get to the actual question.
