Electric Motor Polyurea Grease

[Youngblood]

I been doing a lot of research on polyurea grease lately to get several pump rooms back up to spec PM wise (because they have been neglected).

Here is the question I have. All the motors that are lubricated by grease have a factory fill of polyurea. To my knowledge all of them have been regreased with a lithium based product. How can I flush all the lithium product out and regrease them with polyurea? Can it be done without disassembling the motor?

How critical are the motors?
I used Chevron SRI grease in the motors I maintained. Chevron tech support has a listing of greases/bases that are compatible.

If the motors have a overfill/drain plug then I would flush out as much old grease as possible and call it a day. If they don't have a plug then you might need to disassemble.
