My ER pulley ID is .825" / mating shaft OD. 810". (.015" difference).

Again from recollection, the headstock pulley was non-standard and required a standard bore pulley to be bored out to 13/16". Man, I hope I 'membered correctly.

Soda can WILL be the solution. Here's a photo of what the shaft looks like. I would think the previous owner would have realized there was an issue before it reached this state.

Well, it was painted orange which calls the previous owner's observational skills into question to begin with...
