Adapt a sears craftsman 4.2kw model 580.327140 generator [generac] to bcs605 tractor

The generator cost me $80 but would not start. I thought I could get it running but the generator engine has failed. I want to adapt the generator to my bcs tractor. The generator receives a tapered shaft from the failed engine. I think I will use the failed engine's tapered crankshaft mounted in the crankcase to drive the generator. Machining a tapered shaft to engage the generator and installing pillow block bearings to stabilize the shaft is cost prohibitive. Do you think I can remove the flywheel and bolt a 2-pulley system on the flywheel end of the failed engine crankshaft to get the correct shaft speed? I would remove the failed engine piston but I am concerned about the lobes on the crank causing vibration. What do you think of this project? Am I on the correct path? Its fun to make something out of nothing. I enjoy the process.

Probably a 3600 RPM generator. What speed does your BCS run at? Is it the same or higher horse power.

original engine 7.8hp at 3600 rpm. I think the bcs PTO is 1000 rpm. So I will have to install belts and pulleys to get the proper rpm at the generator. BCS605 has a gx390 engine; 13hp

The generac engine crankcase assembly is aluminum [part # 21857a] and receives the steel bolts that hold the ignition coil pickup. Those fittings have been broken off and I do not think they can be repaired. I cannot install the ignition coil pickup. Is this generator rehab a lost cause?
