Space Odyssey
Williams, 1976This is my first time having a problem with a score motor. Game is space odyssey. Power up and armature engages and spins going to first gear. They dont appear to be stripped but im not sure. I can spin it freely no problem if i engage the biggest gear. Nothing is gummed up or tight.
I checked the resistance .5 is not correct is it. Alot of the fuses were over fused when I got it.
Thanks

read-up here on "Lubricating a Score Motor" http://www.pinrepair.com/em/index3.htm#motor
brass gears designed for no lubrication
there is a felt pad on the side of the motor,
I recently found this thread: https://pinside.com/pinball/forum/topic/modern-equivalents-of-gottliebs-white-lube-black-lube-and-fine-oil#post-730948 suggesting ten drop of "fine oil"
Quoted from metalguy:It does pull in and spin but maybe it’s not the entire way in. If the resistance is low in the coil wouldnt it not spin at all? I’m not sure
I tried getting a reading on my The Wiggler score motor and got nothing ( the machine does work
) I would have expected to see a very low resistance as you have posted above.
my particular score motor doesn't have open brass gears but does have the armature that will pull in and engage a gearbox
IMG_2316 (resized).JPGIMG_2317 (resized).JPGHad a similar issue on a "Space Mission" a few years ago. Ended up getting a rebuild kit from PBR and rebuilding the motor.
So I think I got it. The smallest gear on the bottom back ( top of picture ) that meshes to the armature. I'm not sure if those 2 pieces are supposed to have teeth or what but they seem to be almost completly stripped. Looking for a blowup image or sketch now.
Quoted from metalguy:Got the new rotor/armature from pbr installed. It was stripped. Just 2 small teeth on that thing. Had to drill out the brass rivets then I used machine screws thru the frame to resecure. Works fine now. Thanks
Good good.
