Hi Iceman,

First, here is the relevant page from the Illustrated Parts List, for your clutch shaft and drive axle:

Are you trying to remove the sprocket, Item 24, from the clutch shaft?

Have you removed all of the items on the outboard side of the sprocket, and removed the clutch shaft and clutches from the tractor? At that point, the sprocket can slide off the shaft. I don't understand your reference to a tiny grub-screw, please explain where it is.

I agree that sometimes when a sprocket is rusted onto a steel shaft, it can be fairly difficult to get it off. My practice when collars, bearings, sprockets etc, are frozen onto shafts has been to soak them in Penetrene or another highly effective penetrant (don't waste your time with WD40 or similar non-penetrating substances) then attach a split-ring behind the sprocket, put the shaft in a hydraulic press, and apply 30 tonnes of force if necessary. Even that won't work unless your penetrant has done its job, though.

From what you have said, your machine may be fairly substantially corroded due to neglect and damp storage. Your clutch problem may have been simply due to corrosion on the aluminium clutch disk, and it may have corrected itself in service.

With regard to the type of lighting you can run with that engine, please tell us the Model, Type and Code so we can try to find the alternator current rating from the engine workshop manual. Essentially though, the most effective way to do the job is to replace the filament type globes you are using with Light Emitting Diode type globes. This increases the efficiency from 5% for the filaments, to 50% for the LEDs, so you can use the same wattage as your old globes and achieve ten times the light output. Of course careful shopping is necessary to buy LED globes at a sensible price: I tend to spend some time on ebay before making a choice. Most likely something in the region of 5 Watts per light should be appropriate for giving you lighting similar to car headlights. If you really want to melt the bushes and blind your neighbours, though, you could look at something like this:
