Hi Thomas,

Thank you for prompt response, I was hoping that was the situation and will take a fly at it tomorrow to see if I can get it to come off.  

I have a bronze replacement, the other one lasted about 12 years, so I thought I'd be better served by using what I have.   I'm intrigued by the stainless wheel, I'm assuming that it is cast in one piece using a lost wax or foam based pattern which gives it better quality and is better balanced than the sand cast bronze one where it looks like the cups are welded to the hub.  

We can only run the wheel from around the end of Thanksgiving until the first part of July, when it's in service we can easily top it out at over 30 amps but that would be a waste so we normally run it just below 20 amps or even lower if the weather is nice.  In the spring time we have more power than we know what to do with.    We also have about 2800 watts of solar, plus an 8kw generator that we set on auto-start to where it might run a couple of times a week for 2-3 hours each time during the summer when we barely have enough water to take care of irrigation, domestic, and fire protection.

We have a Harris Wheel system with a permanent magnet alternator, it's been in service about 12 years.   Decided to replace the wheel as it's worn pretty good but its corroded up down inside where there's an allen drive screw and I'm thinking I won't be able to get a wrench to hold it.   The wheel is bronze but it looks like the allen drive screw is steel and the dissimilar metals look like they acted on each other pretty bad.    I can't find anything that shows how the wheel attaches to the alternator spindle, do you know of anything that's available to help with the replacement process?     Much appreciate any assistance you can provide.
