I have gotten the starter clean up commutator turned and put back together. I picked up a new 6v battery and I think I'll put it back together as is as try it.
I need to get a propane tank and figure out what type of hydraulic oil it needs.
Anyone know what fluid to use for the hydraulic system?

Continental is probably right... Yes, i could be a 12v starter..but you have a 6v battery , so that does not add up... Not sure how he determined the wire is RIGHT.... Yes, the starter will run with either NEG of POS ground.... The GENERATOR appears to be 6 v and POS ground voltage regulator..
You need to determine if your going to go 6v or 12 v... then the "wire" can be determined to get the generator to work right........ at this point in time, i think you have a 6v battery, 6v starter, 6 v generator and POS ground regulator.

A guy stopped by today that was a former Allis chalmers mechanic. He pointed out the 12v coil. He looked at the torn apart starter and thought it looked fine minus some tlc.
Was his opinion that it was swapped to 12v at some point. Said it is a continental engine? He said it should be wired correctly as well.
Recommended cleaning up the starter, throwing it back together and trying to start it.

I'll have to swap the cables around on the battery then. I'll probably toss the armature in the lathe and clean up the commutator.

Just opposite of what it was 70 years ago... THe REGULATOR says POSITIVE GROUND so the battery + terminal would go to ground and the NEG battery terminal would go to the solenoid.... solenoid OUt goes to the starter......... but as i said, the starter really dont care... the Generator and regular want the POS GROUND if you get that far.
Starter looks normal for 50- 70 years old.. Lots of grime, rust, and bare wires.. Make sure no bare wires are touching the case unless they are GROUND WIRES... you may have to wrap some tape around a few bare spots... Wash the rotor to get all the oil and grime off of it......... i like to take a pick and scratch the crud between each bar on the commutator to make sure one is not touching the one next to it... You might want to run some steel wool or VERY FINE PAPER over the commutator to get it shinny.... drop of oil on the bearings when going back together.
photos post best if 800 x 600 pixel size...( your photos are taller than wide.. so you might try 600 wide x 800 tall size).. You can shrink them prior to down loading, or shrink them in the Down load Page prior to POSTING.

NO... the Generator or Voltage regulator has nothing to do with STARTING the tractor.. All you need is a starter and a Battery / Ignition switch...... What normally gives a "no start" is the cables are BAD, the battery is weak, the starter solenoid is bad, or the key switch is bad..
Jumper the starter on the bench and make sure it will run.. They run SLOW on 6 volts.... Cables have to be VERY GOOD condition, no corrosion, no bad spots... nothing that will cause ANY resistance... as you dont have a LOT of VOLTS to start with... Starter cable runs to the SOLENOID.... Solenoid cable runs to the BATTERY... Make sure both are good shape, shinny, no rust... and that the Solenoid is GOOD.
If the starter just BUMPS but will not crank enough to start the engine... Put your 12v battery from the Truck in it and try that.. Dont matter what side is grounded ... you can disconnect the BAT wire on the voltage regulator if you want...

The 6v battery is still there, so I'm assuming it's still 6v.
Not sure what parts they were looking for ether. I will clean it up and put the starter back together. I have to do some research to find out what's what for the maker of these parts.
I'm wondering if a previous owner hooked up the battery wrong it wouldn't start and they gave up. Assuming it toasted that box, that would also kill the starter too correct?

what "PARTS" did he need for the starter ?? Something major, or just renew ? Can you put it back together and then test on the bench ? HE should at least have cleaned the commutator, straightened up the brush faces, and reassembled for you ? If it is a little weak, you can run it on 12v to get a little more PUSH.
I have a hard time believing "you cant get parts" for the starter ? What is the model and manufacturer ? There should also be a "replacement" that could be used instead of this original..... maybe a 12v unit ?

starter really does not care if you run 6v or 12v or what is grounded...
the distributor should work on either, but the COIL will be specific to 6v or 12 v .. or have a resistor added if you change to 12v..... polarity of the wires needs to be checked... the "ground" side of the coil goes to the distributor.
you have a Generator, not an alternator... it was probably 6v in the beginning, could be 12v now... but the paint makes it look original... Generator may be OK, but the Voltage Regulator box mounted to it needs to be setup for 6 v , or 12 v, and proper ground... by now, it may be fried.

Recently picked up this FB 24 20. Not sure about serial number but ID plate has #8792045, and # 1342 on it. This was purchased as a non running machine, but owner states it was running about 1-2 years ago. Said the "starter quit". Took it to a repair shop and the guy couldn't get repair parts. I got the starter in a box all taken apart. It honestly looks ok minus some ware. It needs a lp tank, and most likely brakes. A new hose from the top cover down to the regulator/vaporizer thing looks brand new. Forgive me if I'm not calling things correctly. A main question I have is the battery looks relatively new. Made on date of 9/20. So could have been idle since then. Nice 6v commercial 3eh battery. Haven't tried to charge it, bit the positive is connected to the positive and negative to negative ground? Thought there were suppose to be POS ground. It has a box on the alternator that says POS Ground 6v. I'm wondering if someone hooked up the battery wrong when they swapped it and it wouldn't work? Would this have fried it if it were hooked up wrong? I'll need any help I can get with this. Not new to mechanical stuff but this will be my first forklift. I'll most likely need to do brakes to some extent. Any help would be appreciated.
