SO... i bought it. It was a steal at $250 i think.
Needs some playfield love for sure.

Heres the history behind this one.
Apparently in 195x the owners used to play this exact same machine at an arcade on Balboa Island California when he was a child in the 50s and it was his favorite machine.

At some point after the child's father bout the machine from the arcade from him an its been on a trip thru Pennsylvania and finally ended up in Texas with the daughter of the child who was the current owner.

They tried to get the machine repaired a few years ago and something went wrong and the owners state that the transaction went bad and the machine wasn't repaired. They were right if current state is any indication.

So far ive repaired some broken wires, adjusted a bunch of switches that were way wrong, bent the score motor frame in to the correct position so that the stack next to it doesnt short and have been able to sort of play.

I cant get GI lights yet it seems and It wont goto game over. Theres a nail in the bottom of the running man unit where a roll pin should be.

All the steppers are gummed up and need some rebuilding and theres enough grease on the mechs under the playfield to take care of my trucks transmission.

Does anyone happen to have a schematic for this one? Ill email PBR monday and see if they do.

Also if i need parts whos the pitch and bat parts goto man. I would really like to get an original bat instead of the plastic one.

Any ways, heres some pics.

Just trying to get it running currently.

GI Lights are now fixed, I think the game over and runs not showing is an issue with the steppers. Rebuilding steppers is next.

So much grease bleh.....

I cranked the rheostat and the bat is way fast. I think ill turn that down a bit

Went over the playfield with novus 2 and it did a decent job of removing blemishes and dirt

Anyone in town is welcome to come play.

Give me another 20 min....

Ken you mean I don't repair well NOT under the influence.

Jason. Cow poke is next...

512 Ipa . Its perfect

Well ive finally found some time for this baby.
Ive rebuild the 3 steppers and have them working well. The credit unit was a mess but is now working as expected also.

Im running blind with out a schematic but am thinking of drawing my own. anyone done this?

The next unit of order is removing all the grease and clean up the units under the playfield. I think there is about a pound of grease on these units.

I decided to use Formula 88 (cleaner and degreaser that is 5$ a gallon) and my trusty harbor freight ultrasonic cleaner
First up , batter unit

Ive had time to clean the pitching unit. There was a ton of grease on it as you can see.
Having cleaned it ive uncovered a few issues.
1. The coil is toast. Im trying to find a new one but have no clue. All of the manual pitch style units 52 and earlier had this coil so im hoping someone can come up with a coil number

2. The round bar/peg that pushes the teeth bar forward into the pitch spinner mech has a huge groove it. Im not sure if thats normal but if its not I guess ill need to JB Weld that and see how it holds up. Id bet that the part itself is unobtanium. I need to mess with the actual pitch spinner first to make sure that is mechanically ok before i decide anything

So lately ive been trying to start a game.
I couldnt figure out how to start. The only user interaction that I saw was the bat handle. I couldnt find any trace from the bat in any way to the reset coil.

I have one of the original cards and it says "Press The Button To start the Game". No freaking button on my machine WTF.
So the only other thing i see to press is the coin return mech. I took out the nickel unit and lo and behold theres a switch in addition to all the coin stuff.

I trace the switch back and lo and behold it goes to the reset coil. So.. clean and adjust the switch, score motor reset relay.

Nothing

Well the only other switch in the circuit that i can figure out goes from the score motor to the lock relay over to the credit unit.

Suffice to say the credit unit is for lack of a better term JACKED. The switches are in a position that never woudl work with the way the unit steps up and down. Its pretty much the same as the later williams credit units so i disassemble and clean the thing and then put the switches in the way that it makes sense (i think)

2 simple switches with one long blade and one short blade.

I adjust the switch i think is 0 position to open at 0 and closed at 1 credit which jives with a similar schematic and the fact that you cant start a game with 0 credits via the button.

I adjust the other switch i think is the max credits switch to closed and open at max.

Plug it up and VIOLA I can start a new Game!!!!!!!!!!

SO because im anal and want to verify my fix i try the switches in all possible positions with credits on the machine which is a huge PITA because the top panel has to come out and the credit unit is at the worst possible position ever.

It seems as if i have it correct for now. I think now electrically I have it at 85%. I still need to rebuild and adjust the runner unit so that the runners stay on and run to the correct bases.

Im excited to be getting further along as im really wanting to start in on the playfield

update.
I finally cleaned the rest of the pitching unit. The interesting thing about this is I think its the last year 52 that williams used the pure mechanical ones.

After polishing it up and cleaning out the grease and some adjustment with the help of Btw75 it works wonderfully.

Now im working on the running man unit and making sure its adjusted properly.

The men seem to overrun the bases so the base lights do not come on. Im not sure if there should be a clutch onthe motor or whether the latch on the running unit isnt shutting off on time.

I also sent a backglass request to bgresto so we will see how that turns out

here are some before and after pics of the mechanical pitching unit

OK more work done.
So ive going thru the running man unit. There is a loading coil that is supposed to activate so that the men get pushed up above the diamond.

I noticed that the coil bracket had been bent up so that any time the player passes the loading coil a player pops up.
This became evident when a double loads a man on 2nd and a man on 1st

Im pretty sure that thats not how baseball works. Thats not how any of this works!

So i unbent the relay bracket and screwed the loading relay assembly back into the correct position.

Great! except for the fact that the coil never pulls in. never. So now when a run happens no man ever loads onto the diamond. Hmmm baseball doesnt work like that either.

Tracing the wires looks like everything is there and continuity check out. Still i couldnt figure it out.
I did find continuity between the running man switches and the whole metal assy. Thats not good. Turns out that the switches had worn thru the fishpaper. Fixed that on 3 switches.

Better but no loading coil. the switch that activates the loading coil was jacked from a previously done repair so i replaced one of the blades to make that sound.

loading coil does seem to work on the lock in circuit so i knew that the coil itself was good

Off to the schematics. Oh wait thats right. no one on earth has a schematic for this machine
Luckily i have schematics for the year before and year after.
Interestingly enough the wire colors for this circuit and the circuit itself is almost exactly the same from 51 - 53 it looks like

heres the circuit

schematic

easy enough lets check the wires.

blue/white from motor relay switch to loading coil checks
blue white from the outs unit to the jones plug to the single switch works
single switch to second jones plug male connectors check out
second jones plug female connector to motor relay switch ........ hmmmmm i think i might see the issue

missing wire on female connector

non existant blue / white wire

for some reason the entire wire was missing, gone ,verschwinden.
SO long story short. i went to the garage and found an appropriate piece of blue / white wire and fed it thru the harness.

Baseball now loads running men correctly!! Im really enjoying working on this machine. Now to figure out why the bell doesn't work when the running men load
