Bearings for pump motor

by Ed
(Texas)

I need a new bearing for my Dolphin Diagnostic pump motor. I have found the bearing for the 'output' end of the motor (near the pump thingy), by reading the bearing number from the old bearing.


However, the bearing on the end with the electrical connections is damaged such that I cannot read the numbers. This bearing is about 3/4 inches in diameter outside, about 1/4 inch inside, and about 1/4 inch thick.

Does anyone know the part number of this bearing? It should be on the side of the bearing, and include "6Rs" maybe.

Thanks.
Ed.

Bearing part info
by: CT Pool owner

I had the same problem. The pump motor had a lot of resistance from a seized bearing in the motor. The Dolphin would run for a few seconds in each direction and then shut off. Replaced the bearing at the top (power wire) side of the motor. It's a 625ZZ bearing. 5mmx16mmx5mm.
$8 shipped from ebay. Now it runs again!

Bearing numbers
by: Anonymous

I have a motor number with that bearing:
Three separate stampings:
NMB
R1650HH
625ZZ

I hope this helps.
Let us know if this fixes your problem. Ihave seen the plastic housings melted around this bearing so it must get very hot.
