1. This is for a 1 hp magnatek centurion motor ( I believe a. o. smith owns them) attached to a hayward pump housing for an inground pool. Did hayward use magnatek motors at one time or is this a special setup the pool installers used? I have a part number off the motor and a 3 letter "Form" designation KJM. I can see the stamped hayward tag on the pump but can't make out any numbers. I'm not sure, therefore, that I have enough information to be able to track down shaft seal, housing and diffuser gaskets for this setup.

2. If there is enough water that it is running under much of the pump/motor and off the concrete pad would this indicate that the likely problem is the housing gasket rather than the shaft seal? Could there be a lot of water leaking out with a shaft seal problem?

3. Is there a way to distinguish whether the problem is the shaft seal or the housing gasket? Would I be better off seeing if I can simply tighten the 4 bolts connecting the motor to the seal plate to see if the problem goes away before I do anything else or is this a bad idea? If it ceases to leak at that point am I safe or is there still a danger? Any water getting into the motor housing because of a faulty shaft seal would leak onto the ground wouldn't it (i.e. there is no danger of a leak at the shaft not being noticeable from outside the motor is there)?

4. This motor is about 7 years old, but it isn't heavily used. I run it only a couple of hours a day at most for 4 months a year because the pool is seldom used.

If I disconnect the motor from the pump housing do I need to replace the shaft seals and gaskets regardless of the suspected problem? I'm concerned that if the shaft seal isn't the problem, and I tamper with it, that it will become a problem.

I know its a lot of questions. Thanks for taking the time to read it.
