Hi - New to this forum and also the Galion 160 I just bought. The serial number reads 160CMD01031. It has a Cummins motor in it. I assume this grader was made back in the early 50's. The motor does run, and most of the hydraulics work. When I bought it, the generator had been removed due to a bad bearing. All of the wiring has been bypassed / disconnected. I would like to get the instrument panel and gauges working again as well as the generator. I have rebuilt the generator - it is a Delco 1106805, which is a 12 volt. Stamped on the starter motor, it says 24 volt, so I am therefore confused. Did they really use 24 volts for the starter and 12 volts for the rest of the system, or have some wrong parts shown up here? I have not been able to find an operation manual or wiring diagram for this grader. Also, are there any basic manuals available for the Cummins motor? I would like to find a list of capacities and what all the various filter numbers are. Stamped on the Cummins block is a number: 10442-2 IS this the motor ID, or do I need to look somewhere else for that? Any guidance you can provide this Galion newbie would be greatly appreciated!
There is some useful info here: http://www.steeringclutch.com/transmissiondiscsGALION.htm Scroll down to 'Motor Graders' and look for your model. Note 'Lubrication Specifications' at the beginning of the graders section. No info on engines though. If engine is a Cummins, there should be an engine data plate riveted to the accessory drive case just in front of the injector pump, however, many have fallen off, been removed, been painted over etc. There may be some empty rivet holes on the curved face of that case where the tag was.
If you have 2 12volt or 4 6volt batteries Follow the battery cables and the starter cables ,if they met up at a large solenoid switch it still has a series parallel switch. Bob
Thanks for sending the steeringclutch.com site. Yes, good info there. I'll look to see if there is an engine data plate where you said to look. I don't remember seeing one there though... may have already disappeared.
Nothing but bare bones wiring on this machine now. Someone in the past really took an axe to the wiring. One battery cable goes direct to the starter and the other goes to ground. No series-parallel switch to be found best that I can tell. So- apparently there were some wiring variations that they used on the old Galions which included a switching arrangement which used two 12 volt batteries that allowed 24 volts to be applied just to the starter and then when running normally, the two batteries were connected in parallel for the rest of the equipment (lights, instruments, heater, etc) to run from just 12 volts? The previous owner was running two 12 volt batteries in series. I see by looking at the burned up gauges (which state they are 12 volt) that someone must have put 24 volts to them at one time, which fried them. The fuel solenoid should be a 12 volt device right?
The fuel solenoid could be either. Bob
I have not previously come across one of these "series-parallel" solenoids, but see now that this is exactly what this machine needs to work with the existing electrical components and system. I came across a great Delco service bulletin (1S-135) that shows the wiring and theory of this device. Anyone else needing some direction for the use of this solenoid should have a look at the bulletin. Here is how it is typically wired:
The cummins fuel solenoid has a knurled head screw on the back side of it that manually shuts off the fuel, in is off out is on. Bob
Bob - Regarding the fuel solenoid - I want to hook that back up to a switch on the dash, so should the manual screw be left in the closed position for the solenoid valve to work properly?
I guess that is confusing, turning the screw in turns the fuel on bypassing the solenoid ,out allows the solenoid to work .Power to solenoid turns fuel on. Solenoid should be marked 12 or 24 volts. good luck Bob
OK thanks Bob. I would think the solenoid would be 12 v but I'll scrape the grime off and see how it is marked. What do you know about the fuel tank sender? I want to put on a new fuel gauge, but dont know what the resistance range is from the sender.
Hi Bob - just noticed that in one post you said that turning the fuel solenoid screw -IN- turns the fuel OFF, and then in your later post you said that turning the screw -IN- turns the fuel ON. Which is it?
Turning it in turns the fuel on.
Sometimes I get in a hurry ,first post meant in turns off solenoid control , turned out turns solenoid on ,that is if it works. That is what the screw is for . Bob
Thanks for the clarification Bob. If that solenoid is working, should I be able to hear it "click" when I apply 12v to it? Have not tried this yet, as the wiring is still in shambles, but just curious.
