What I have heard so far is:
1) I can get the tower down by removing the safety guard and the v belt and
turn the wheel by hand. It will take a long time to do this. Down is much
easier than up. Be careful. Take rests. Halfway down gives me a lot of
2) US Towers sells a crank. It takes a long time. I plan to call them on
Tuesday fir suggestions.
3) this doesn't sound like a motor capacitor failure, which would be noisier.
There are a couple of socketed timing relays that I should try swapping
I'm away until Wednesday morning, and I'll start on this then. I'll let you all
know what I learn.
