While doing a repair on a Spectrum 2-8-0, I managed to damage the top thread on the engine axle for the screw that connects the drive rods to the axles. This screw part number is G814X-MTD10. It is about 1/4 inch long, fine thread, total diameter of the stem of .115". I need a tap for such a screw. What would be the size? and Where would I find such a tap? Thanks.

I am in a 'bind'. Have a jam (probably plastic shards) in the gearing. Can't seem to find any detailed instructions for disassembly. Perhaps disassembly is not recommended for the novice without special tools. This was a fine running machine before this mishap. The model is 51196 Spectrum. Know of any simple ways out of this mess? Any suggestions?
