Proper way to re lubricate an electric motor?
2/25/2003 9:11:18 PMBHedberg
Could someone please explain to me the Proper way to re lubricate an electric motor? It's for a Dual turntable. I want to know what oil/grease and where to put it and what the diffenent parts of the motor are called? I'm getting wavering and the motor sometimes grinds and makes a bit of noise but sometimes it's fine and smooth.

Thanx

Hi,
If you have a hobby shop near you, pick up a bottle of "Labelle" Light oil, and Medium oil, and a tube of Light grease. If these are not available, you can substitute "3in1" for the oil, and any wheel bearing grease with "FORD" as part of it's description is lightweight enough, and also contains molybdenum, which cuts down friction (Most important is that it does not get hard like some greases do.

The motor armature (the part of the motor that spins) is held in place by two bearings. A drop of Light oil on the shaft where it comes throught the bearing/bushing on each end is all that should be required, but push the armature axially (in line with the shaft) to work the oil into the bearing surface. Sometimes felt is visible, if it is, put 2 or three drops of the light oil into the felt.

Where the platter turns, put 2 drops of the medium weight oil on the platter shaft bushing, and if there happens to be a ball bearing that the platter weight bears on, clean the bearing and the steel washers that ride on each side of it with a solvent, or alcohol. Grease it with the light grease and reassemble those pieces.

Wherever there is a pivot point (such as the tone arm, or some of the levar arms, a drop of the medium weight oil is usually sufficient, and any sliding surfaces that are in contact, such as where the control knob levers are retained by a spring washer/clip,- grease them. Wherever there is a sliding contact point, such as where one arm pushes against another, grease it too.

There is no guarentee that these lubes will eliminate the noise if there is just too much wear in the motor bushings, but this should take care of things if the noise is just the result of a lack of oil.
