i have a hayward super pump 2 1/2 hp and # SP1620Z1M.  I followed the directions in your video and looked at the chart but when i search your site for these 2 bearings, it comes up with multiple bearings. Can you tell me which bearings i need to order please.   I came up with: UST1252 604005-001 100025-002

Thank you in advance

Your UST1252 motor would require one 5270-31 bearing and one 5270-32 bearing.
