The problem is at the end of the shaft where the fan connects there is very little space to get a strap onto it. The only other thing I was thinking was to remove the fan blades. Perhaps I'll reach out to Hayward.
Hello,
I too have this issue and a strap wrench on the impeller still doesn't work since the leverage on the impeller is better than the flathead on the end shown in the above picture. Any other tools or methods recommended for disassembly?
Thanks!
