I just bought an old 933 Track Loader. I am curious what year it is. Can you tell me where to find the serial number? What years did they make these? It has a 6 volt charging system and a cab. Its a diesel and no pony motor. Were these all approximately 70hp and 9 tons? Thanks.

Look on the upper LH rear of the transmission/steering clutch case and on the LH rear of the engine block for serial numbers. If it is a 6-volt unit it will be a 11Axxxx model.
Must be a pull start if the pony is missing. It would have to have a 12v or normally a 24v system to be direct electric start.

Pull start as in tow it to start it because the Pony motor is missing? It is a running work ready machine and it has an electric starter. It has 4 6 volt batteries. The former owner said it came with two when he bought it and he added two more. Are they wired to be 12 volt maybe?

These machines were 24V direct electric start if it was from the factory that way. I wonder if he had the 4 batteries wired in series?

Serial number plate is on the left side of the engine, toward the rear. Just about where you would have worked the pony engine levers.

Could be 12 volt if it is a conversion starter. Does it have a remote mounted solenoid or is the solenoid mounted directly on the starter?

I'll check the serial number tonight and get a few pictures. I thought it was heavier. Thanks for all the replies.

To determine the voltage of your starter check the wiring and polarity of your batterys. If all 4 batterys are wired + to - in series then you have a 24 volt system. if only 2 batterys are wired that way and then are wired in parallel to the other 2 then its a 12 volt system.

Yes, you can find the SN plate without removing the hood or side panels. On the left side of the machine, stand by the battery door. On the block, just in front of the battery you will find a plate to wipe the dirt off of.

In this picture, look at the battery end where it says "Jan 02." Then look left 2" and down 2" and you will see the SN plate.

Good luck,
Sam

Sorry for being dumb I don't see it in the picture. Also my batteries are in the rear behind a door that folds down. There are 4 6 volts I'll have to check on how they are wired. I didn't get a chance to get pictures last night and I couldn't find the serial number but the manuals I got with it say 42A1 and up.
