Motor and impeller maintenance - lubrication?

[dmc]

My cyclone has been working great for 7 or 8 years now, but has developed a squeaking noise when coasting to a stop after use. I can't remember what if any grease fittings are in the Leeson 5HP motor, and it's not that easy to get into the ceiling where it is mounted. Could someone remind me of the suggested maintenance for the motor and impeller?

I think you are hearing the centrifugal switch that controls the starting winding. It drops out when the motor slows down. Mine has always made a slight squeaky sound when the speed has come down quite low. I remember no grease fittings on this motor and the leeson site implies that no lubrication is required.

Thanks BabaBrown, I might have a peek at it one of these days, but I'm hoping you're right about the source of noise and that's it not a problem.
