So the bearing spun in the casing? Are they plain brass bearings?

If you are going to make one - I would try a self lubricating bush? (Called Sullube from memory)

Much better - bronze with a graphite type lube in-bedded with the steel.

You don't need to lube these things at all...

Local bearing shop will have them in all sorts of sizes.

It is a brass collar, just made of tubing. It fills the distance between the top of the casing and the shaft. The collar is supposed to bind to the casing and allow the shaft to rotate. What had happened, was the collar became bound to the shaft, and rotated against the casing. very sluggish. It is not a bearing (as such) but is works like one.

Great job saving that motor Nino
it always scared me the thought of having to rebuild one of these things, i've been real lucky so far and havent had to touch the score motor on any EM i have ever worked on!!

Looking forward to further updates, Will you do anything with the little bit of wear you have just above the flippers?

Not sure yet, Mitch. The rest of the playfield is ok. Any suggestions ?

Thanks a lot for sharing that with us Nino . I think, as others have said, seeing your detailed pictures and de******ion will give confidence to anyone faced with a similar problem. I reckon you should add a "Score motor rebuild" thread to the Hint and Tips section so it doesn't get lost over time.

Once I'm done, I will add more pictures and create a seperate thread
