I had to have a central heating pump rewound because I could not shift the nuts on the base, 24" stillsons with an old fork stanchion would not shift them and as it was a bit cold without heating a 24hr rewind seemed worth it but a bit pricey compared to a new pump. I think the boiler was over 25 years old when it got replaced so two pumps in 25 years didn't seem bad. SEW eurodrive sell stators as a spare part and do not recommend rewinding especially in applications where two motors are working as a pair, they reckon a rewound motor is 5-10% different from a factory part. For a Myford a new motor is not expensive and as John says a good opportunity to go for the inverter option unless your motor is 3 phase already.
