Well it was like this:
I went to the roof to hook it up, every year with the high calcium it's always a joy because everything is rusted and calcified no matter what steps you take to prevent it for the next year. I had to replace copper tubing going into the cooler up top, the connections in the garage were leaking and I had to replace the valve. Still leaked at a different connection so I had to replace another ball and nut assembly.
Got everything ready to start up and... . nothing. One of the bearings the fan rides in was seized solid. Just pull it off and replace it? no way. . that sucker had to be broken down into pieces to be removed. I got the new bearing on and away the fan went... no water from the pump. The calcium had froze up the pump shaft, luckily I broke it free and lubed it up and it ran fine.
Then I noticed a rubbing sound, the new bearing carrier was about 1/4 of an inch shorter than the old one so the fan was rubbing on the housing. No problem, I took the bearing out of the housing and put it in the old housing. Now she is singing along but at 104 degree's it had me just a little HOT and bothered
