This isn't going to be what you want to hear, but the fan shaft was the most difficult part of restoring my 50. Since I had already removed the radiator, I had room to work. In your case, to get the shroud off, you'll have to remove the fan shaft. Read all of these steps before proceeding. 1. Remove the belt. 2. Remove the bolts to the fan shroud and the two bolts under the front fan shaft support. 3. Remove the bolts that mount the rear shaft (ventilator) housing to the governor case. 4. The shaft has to come forward about 1/2" out of the governor case as there is a shoulder on the fanshaft housing that centers the shaft in the governor case. It may be a tight fit so work the shaft back and forth a little to walk the shoulder out of the governor case. Put a piece of plywood between the front of the fanshaft and the back side of the radiator so when it comes loose, you won't poke a hole in the radiator core. 5. Be careful to keep track of the gaskets at the rear end of the shaft as they act as shims for the correct backlash between the gears of the governor and fanshaft. (The ventilator housing at the rear of the fan shaft stays with the fan shaft assembly. Separate the mating surfaces between the governor housing and the back side of the ventilator housing.) 6. The shaft has to come out from the flywheel side of the tractor. I don't know exactly what else you may have to remove to get it out (air cleaner, throttle linkages, choke lever), but the service manual says it can be done without removing the radiator. 7. Move slowly and carefully. The greatest pitfalls during my restoration happened when I got in a hurry.
