I recently acquired a Fireball Classic that overall works great, but the spinning disc in the center of the playfield is somewhat unreliable. It will occasionally stop working within a game and/or spin very slow.

Any ideas of servicing this?

Check the wires that connect to the motor. They may be loose. Also clean the plastic gears on the motor while you 're down there.

Does the disk run freely when spun by hand?

Does the disk run freely when spun by hand? There are no plastic gears on my FBC. Are your gears gunged up by old grease? How hot does the motor coil get? Does the problem get worse after a while?

Thanks to all who posted. I basically did everything suggested. I disassembled the unit, cleaned it and oiled all of the gears and bearings. Must smoother and quieter now. I also resoldered the connection. Seems to be working great now.

Also, all of my gears are metal...no plastic.

Very happy for you, should imagine it would be very hard to replace this motor

I had this problem with a Fireball Classic. It spun slow because the drive gear wore out the hole to an oblong shape and the spindle was now rubbing against the Ferite core because of being out of proper position. I have temporarily fixed it by using a very thin nylon tie wrap and looped it around the spindle, tightened it to pull it back into the non worn side of the rounded out hole and greased the nylon to spindle contact area to minimize drag. Now it spins the proper speed. The permanent fix will be to send it off to PBR for a rebuild at least. Hopefully Steve can put a new bushing in place of the rounded out one. That is if he has the parts to rebuild this type of motor gear box assembly.

That is an amazing bodge. Well done
A new thread on amazing bodge's should be started ....but not me, my whole life is a bodge
