Over the last several days, I've started to get a louder "grinding/oscillating" noise coming from my Hayward Northstar 1.5 HP pump. Also, I just noticed that some grease has come out of the back end of the motor and dropped on the concrete and re-solidified. I'm assuming that the grease came from the back bearing -- and with less grease, that usually means more heat and more wear, so I'm guessing that this thing will seize up in the not-too-distant future. Rather then have to scramble to get the replacement parts when it goes out, I thought that I would actually be proactive and get them before I actually need them. Prior to buying anything, I thought that I'd ask the experts for some advice.
1. Do I need to replace the whole motor, or can I just replace the motor bearings? (I'm comfortable around bearing pullers and presses) How hard will it be to identify the required bearing part number(s)?
2. While I have everything apart, what else should I replace? I know that there is a "tune up kit" available with some seals and O-rings, typically does that suffice and is it recommended to replace all of those included parts?
I've got absolutely no documentation on the pump or motor, but have found some stuff on-line regarding the disassembly process, it doesn't appear too complicated, but any procedural "words of wisdom" will be greatly appreciated.
Many thanks in advance.
