Oracle Delphi motor can't achieve right speed... - Page 2

This may sound a little drastic but it could work - it allegedly
was the quick way to run in car racing engines in a hurry.

Fill the bearing with a mixture of oil and metal polish (Brasso ?).

Spin it until it loosens up. Then clean it out and run a bit
with only a small amount of oil for the thrust point to polish
the bushes even further then refill with oil.

I've don't know how long it would take so probably best
to start off spinning by hand ?

As they are Teflon bushes perhaps Brasso is too drastic ?
What about adding jewellers rouge powder to the oil ?
Instead of the Brasso ? After the Brasso ?

You get the general idea, hopefully some-one can
add more knowledge to this suggestion.

At $400 a pop, and I don't know if you get a new spindle,
needless to say do this at your own risk !!!!!!!!!!!!!!!!!!!!

Hello all,

I have an odd question? When the motor is spin from the spindle, by hand, do you feel the resistance(pull) of the magnets? Is this normal?

Perfectly normal, you also get a ripple feel with AC motors,
