l bought a Gottlieb Flipper Clown several months and have just started going through it. The game powers up when l manually make the hold relay but nothing else, the score motor doesn't turn. l went through various switches but noticed the score motor's motor was getting hot, quick turn off and looking at motor l could see it seem to be jammed solid. l removed the motor from the switch frame and was able to see the small armature that the spins has dropped down (picture 2), its shaft taking the cog at the end of the shaft out of mesh, see 1st picture to see where it should be. 3rd picture shows the housing and what appears to be four brass rivets that hold everything in place. Anyone had experience in spliting and reparing these motors?, any advice gratefully accepted.

First thing I would do is spray it down really good with brake cleaner and try to remove all the old grease. Then I would fill both the top and bottom oil sponges with a fine oil (I like Singer sewing machine oil). Then I would try to move the main shaft by hand. In the last picture the oil sponge is the white circle at the top in the center. This may be all that is needed.

Might want to contact the pinball resource to see if you can buy a replacement

The brass rivets can be drilled out to split the frame but that shouldn't be necessary unless you have a broken gear or worn bushings (which all are available at Pinball Resource BTW). Flooding it with a good grease solvent as jsf24 suggests (I favor mineral spirits) and working all the old grease out with a tooth brush will likely get the motor going again.

If you cannot get it going, I think Steve Young actually offers motor rebuild services at a reasonable charge.

l split the frame and wiped the oil/grease away to find the fibre gear cog has stripped two teeth, the small armature seems to have no means high enough on it's shaft to stay engauged with the small gear above it plus the phosphorius bronze bushings seem to be quite worn, (side play). If l can't find a complete motor over the next 4/5 days then it's PBR. Thanks for your input all the same.

You can buy a fiber gear from PBR. You can also get brass rivets and peen them over or thread the holes with a tap and put screws in to hold it back together.
