1952 Gottlieb Chinatown trap hole pinball machine repair: Day two

1952 Gottlieb Chinatown pinball

Day 2

Day two was more like an evening of work on Chinatown. I still have to show up to work a couple of times a week... 

I concentrated on working on the head and reinstalling the score motor panel. Removing the wood clamps and reattaching all the small parts I had to remove to reglue the cabinet. Ball lift rod, ball shooter housing.

The heads stepper units were in exceptionally good condition. They weren't gummed up like I usually see them, they were mostly free but required a little bit of lubrication on the metal on metal pivot points on the set up and reset arms. Also cleaned off the old contact disc grease, burnished the contact pads with and electrician's eraser and reapplied fresh grease.

Once I finished working on the head, I plugged in the playfield and tried to power up the game out of curiosity. The steppers reset properly but all the playfield switches and trip bank trip relays were unresponsive due to corrosion on the switch points. I have my work cut out for day 3! 

Not very exciting stuff, but necessary. Also not very photogenic stuff, hence no pictures, But enjoy a few pictures of backbox details. Also, an interesting detail for Quebec or Canadian pinball aficionados: There is no Laniel stamp.
