Thread: Lubricant for Delta 36-5000 Arbor

I don't think a bit of dust/grit on the arbor is the cause. There is a bearing in there so check that first. Take off the belt and rotate arbor by hand. If it spins nice and smooth then the bearing is fine and the problem is in the motor.

Thanks John.
My blades/dados are set on a shaft directly from the motor; no pulley involved. It is running again, but I just need to get a few tips on maintenance in addition to blowing out with air.
Much appreciated.

If the motor doesn't get up to speed quickly it could be an indication that the start capacitor is on the way out.

This is most likely if it is more than 10 years old. The easiest way to determine that is to replace it.

If the motor doesn't spin freely then the bearings are probably gone and need to be replaced.

Also just check that you haven't filled the motor with sawdust when you blow the saw down.

Spraying it with a lubricant like WD40 will just cause the dust to stick to everything.

WD40 and compressed air are both terrible for bearings.

WD40 will both dissolve any factory grease that's in the bearing and pick up dust as mentioned above, compressed air can send dust and other contaminants around the seals and into the bearing which, combined with WD40, will just form a mess inside.
