Hello, I'd like to replace the shaft seal and bearings, and I suppose the backplate O-ring on my pool pump and motor. Its started to leak, and on very rare occasion squeal. I want to make sure I order the right parts, which is what I need help with. I've attached photos of my motor and pump tags. Thank you!

Sorry for the delayed response. Both of us who work on the forum were on vacation last week.

Your motor would require two 6203 bearings. Click Here to View the Motor Bearings

The shaft seal is part number R0445500. Click Here to View the Shaft Seal

The backplate o-ring is part number 5020-136. Click Here to View the Backplate O-ring

No worries. Thanks for the responce. I saw another post on the forum where someone had the same motor as me and he said that he eneded up needing 1) 6203DW (rear) and 1) 6304DU (front). You guys noted that it might have been a one off year or something. I don't want to leave my pool without circulation for more than a day or two while I rebuild the motor. How can I be sure I do not need to above mentioned bearings, without taking the motor apart and seeing them? Might not be possible I suppose.

I'll forward your motor label picture to our Century motor rep and see if he can confirm the bearings based on the serial number.

The first rep I contacted must have just retired or stopped working for Century. My email bounced back. I'm reaching out to another territory rep. Sorry for the delay.

If you are in a rush, I would suggest getting two 6203 bearings and one 6304 bearing. That way you'll have what you need either way.

Thanks, I did just that yesterday. I'll return whichever bearing it turns out I don't need. Thank you for the help. I'll post which ones end up being the right combo.

I pulled the motor off the pump and got to work. It did take the 1) 6203DW (rear) and 1) 6304DU (front) bearing combo. After putting everything back togethar, the motor is making a high pitched noise while running, and it has a small leak from the shaft. I'm going to have to pull it apart again and see if I did something wrong. Is there a diagram of the shaft seal assembly somewhere I could reference? I put it back in the same way the old one came out, but I'm guessing I didn't do something right. Thank you.
