I had posted about needing a mechanic to replace the crankshaft pulley. It occurred to me that I should explain the situation and see if there is a remedy other than replacement.
Here's the thing. I started up my 2N two days ago. It started well and all was good. Then I heard a little noise that I knew wasn't right. As I got off the tractor and looked toward the radiator, I could see the fan was barely turning. I quickly turned off the tractor. The sound was like a little clicking sound. In viewing the crankshaft pulley, it is not seated firmly against the engine block but has a slight angle. The pulley turns with no resistance. If I use a lever and push the pulley back toward the block, it seems that it is not catching. I checked the bolt that holds the pulley and it is tight. Since I had that problem before, I thought that was the problem but it isn't. Any ideas to confirm that I need a new pulley? If I do, is it at all possible to replace this without removing the hood, radiator, front axle, etc? That is just not something that I think I could do. I could (with difficulty) loosen the generator, remove the belt, remove the bolt that holds the pulley but will the old pulley come out and the new one go in with such a small space? Any help would be greatly appreciated. I really need my little tractor.
