Modification To Submersible Pump

Modification To Submersible Pump MISCELLANEOUS EQUIPMENT Pumps 24-3-39 Isaac Yoder, Blanch, N.C.: "After two years of use, I'm willing to share an unusual money-saving repair I came up with. On our farm well's submersible pump, there is a coupler between the motor and pump. On the pump side, the coupler has a hex shaft while the shaft on the motor side has finer splines. The splines on the motor wore off so we had to get a new motor. A year later, it happened again so we decided we had to do something. I just ground the end of the motor shaft back slightly and put high grade Loctite (the green color) on the shaft and collar and tapped it back on again and reassembled the pump. After giving it plenty of time to set up, we put the pump back in use again. The repair has held up for two years. That's twice as long as when it was new. So I would advise anyone to at least try what we did rather than buy a whole new motor. "I have also used Loctite on bearings, both large and small, high speed or low speed. If an old bearing or race wears down a shaft or collar, just put some Loctite on and position the bearing and it will seize to the shaft. It's a miracle product as far as I'm concerned."
