[Amps] L-4B blade/blower replacement

[Peter Chadwick]

Garry asked:
>Has anyone had to replace the blades or blower assembly in a L-4B?  The 
blade has gotten out of round and slightly rubbing the back of the blade 
housing<

My guess would be that there's a bearing worn out, which is why the fan blades can rub. If you have a machnine shop, you can possibly make a replacement, but I'd look to replacing the whole thing.
