I ran across one of these. OK I know it's gas and loud. Is this usable for some kind of solar battery bank backup recharge generator or power outage generator used with batteries and a 24-120 inverter? I think the 4 cyl mil std gas engine can be converted to natural gas.

If it runs on starting fluid, that rules out ignition and compression, valves etc. Must be fuel related. Maybe the carb float is stuck closed?

Those 80 yr old Delco coils still work great! Check your points and condenser first.

Make sure the front service gladhand cover has a vent and the line is not capped off.

Which glad hand? Front or rear? The front is which will cause this.

Here is what I have.

I've always cranked for a few seconds with the engine stop pulled out. Still takes a few more seconds for pressure to register on the gauge, so yes the rods are getting pounded with whatever oil is still there from last run.

Very unusual. What brought you to the diagnosis of the transmission being at fault? Could the engine be dying on its own? Transmission solenoids only apply pressure to clutches etc when power is supplied to them, so you can eliminate unintended clutch operation by unplugging the transmission...

This?

Suggest you get under the truck with your voltmeter and see what ya got. Do you have 24 volts at the starter? Do you have 24 volts at the solenoid when someone turns the ignition to crank?

I used that same starting technique to fire up my D7-7M dozer using my M275A2 tractor, how I was not killed doing that I will never know.

I would first make 100% sure oil isn’t being ingested via a bad vacuum pump diaphragm or stuck crankcase vent valve.

Is the pump a Bosch? A highly competent injection pump rebuilder should be able to reman it. Your oil in coolant issue could be a pinhole in the oil to water heat exchanger. The TMs for this generator exist somewhere but good luck finding them.

Slow cranking can be caused by corrosion where cable ring terminals are connected to firewall buss bars, or corrosion between the wire and the ring terminal. Feel for very hot connections after cranking.

The (only) nice thing about the CUCV charging system is that each battery gets its own alternator, so one battery can’t “bring down” the other as can happen on other 24 volt trucks. Agree, unless you are running a battery maintainer, 4 years is about it for a typical battery.
