I've repaired a number of pool pumps recently and I'm finding most are 8-10 years old. Usually it appears the pump seal failed and got water on the motor bearing which eventually corrodes and makes a racket or it even freezes. In every case I have to take the motor off and disassemble it to remove/replace the motor bearing. It should be a very simple job and cost less than $30 in parts. But in every case at lease one of the long skinny bolts that hold the motor case ends together is completely frozen due to dissimilar metal corrosion (steel bolt in cast magnesium or aluminum case). These bolts are very long (about 12") and so skinny they twist and then break if there's much resistance turning them. Also often the bearing is frozen as well for the same reason. Sometimes I can drill the bolt out and use all-thread to repair the bolts and penetrating oil/patience with a puller to remove the bearing. At minimum it takes hours instead of minutes and sometimes too much force causes a broken case (new motor). My pump is only 3 years old so I thought I'd see if any of this was starting on my pumps (1hp and 11/2 hp). I turned power off and just tried to turn the bolts in place on the back of the motors. Sure enough, mine had almost frozen already. But with some gentle working back and forth I got all the bolts out. So I put this compound I used to use back in my blue water sailing days called Tef-Gel to prevent the future problem. Seems to me it would be a good idea to do this on any new pump. What do y'all think and what do you use? There are a lot of anti-seize compounds out there. Are any of them proven to work in pool applications? Seems to me that at least the bolts could be done as preventative maintenance with very little effort and save hundreds in future repairs. Also makes me think we should inspect/replace pump seals more often as it's pretty easy.
