I've done it, I bought a Pachinko
It's a 1973 (昭和49 on the blue sticker?) Nishijin Model B! It's not in the best shape... its filthy, its got a bit of water damage and staining on the laminate, and the frame is a little wobbly; but all the critical parts move well/interact correctly (as far as i can tell), and the price was right.
I have watched Mopars fantastic video on the Model B, and i have read JACKSJE4s cleaning thread. There is a lot of really great information in both of those videos.
I still have a few questions that I probably just don't know the correct terminology to find searching the forums, so I apologize if this is the Nth time these have been answered.
(pictures were taken before I started cleaning. I've taken the Plexiglas off as it was very warped. I've already replaced it with glass.)
This is an aftermarket bell, right? What is signalling the bell? How does the yellow 'CB' power lead work? The schematic in JACKSJE4s thread says it is connected to the empty hopper ground? I think this thing needs to be rewired, pretty much every connection to the lights are all intermittent. The bell rang for a moment the first time I plugged it in, but has not made a sound the whole time I was playing with the jackpot and empty hopper switches, or any other time i unplugged and plugged it back in.
The dump mechanism is very sticky, but can be easily operated with two fingers. I've cleaned it pretty well, but it still doesn't like to slide. I've read not to use any kinds of oils, to avoid collecting more dirt, but if I cant get this to loosen up, what can I use to lessen the friction in this area? Graphite?
What makes the leaver above the see-saw rise, what is it connected to?
How does the plastic leaver on the shooter mechanism prevent play? I cant really tell what its doing on the other side of the playfield. Does it prevent the loading of new balls?
Also concerning the shooter.... Is there supposed to be a bumper on the 'hammer'/Shooting arm? Mine is just a somewhat rusty spring, I don't want to destroy balls with it if its missing something, or with the rusty spring if that is what's supposed to make contact with the ball.
