^^^ this guys got it.

depends on the v. 71 and 92 series single block Vs have the governor on the front of the engine. Dual block Vs 12v92, 24v71 etc the governor is in the middle but this doesn't apply to him. lol

53 was the only v series to have a rear mounted governor

no it's going to be the air cut off. That red button on the dash should be your fuel shutoff and there is most likely an electronic solenoid mounted on the governor cover that actuates the fuel shutdown lever on said governor. If the red button doesn't shut it off tilt the cab and check the solenoid for power when the button is pushed. if there is power there then the solenoid is bad.

Those are airbox drains (slobber tubes). As the engine runs the blower pumps air into a large cavity in the center of the block called the airbox. This is where the ports in the liners are. As it runs the piston passes those liner ports and over time the airbox accumulates combustion byproducts oil/fuel/etc and this needs to have a place to be drained. That is what those tubes are. The more you idle this engine the more it will slobber from those tubes. The reason for this is because they don't make enough heat at idle because they move so much air and can actually glaze cylinders. This is why the slobber cleans up after you run them hard with a good load, it actually removes the glaze and reseats the rings. Most guys think they leak oil, but most don't it's just as designed slobber from the slobber tubes. Love the ol pete nice to see one out there still working!

Here's a few of mine.

Cool vids! Do you think my rack needs adjusted? Someone suggested that in my youtube comments, mostly due to the excessive lope on start up.

I went to the WOG rally in 2017 (without the bus) and it was pretty awesome and I'm planning on taking the bus this year. It's a long trip from Maine, but you should go!
This one is an ex NASCAR team rv, it was painted white to facilitate a wrap for the team. I like it white too , looks good with the polished aluminum and its nice and cool at the track too ( I screw around with the SCCA in a GTL car)

Just running a compressor in the original application.

Yours turning 1200, wonder how they got 60hz out of it, maybe a 3 pole generator?
Its a 3 phase unit, 20kw/25kva, a GE powerhead.

Was just remembering an anecdote from an old guy who worked on railroad stuff, said the load sensing bit would go bad and that they'd fix them by wiring the governor lever to the "high speed" position for both unloaded and loaded operation. The 1200 was idle and the 1800 was when the load came on. Making me think that they came set up with a generator built for 1800 RPM use causing confusion when he said his ran at 1200.
I think they would slow down the engine to reduce the frequency to slow the motors down to maintain temps and reduce fuel usage. Odd setup but they run for a very long time.

I believe they were 3 phase and 6 poles? Does that work out?

Thanks, Ive got it setup with either injection now. I was able to start it at -15F, its bailed us out as recently as this fall, we were 6 days without power after a major storm.

these are still available for cheap as surplus and have been documented to run in excess of 80k hours before failure although they are not for everyone due to the old tech...but its all mechanical

Yeah I was pleasantly surprised it started. I usually plug in the block heater the night before, but I decided I would see if it would start without it. Truck just drives straight as an arrow, I love it. Steering it in tight spots and backing up that cattle pot loaded gives your arms a work out.

Slobber is normal if you let it idle or lug. I run mine 3/4 throttle or more it only drips a little when i shut it down. Let it idle and it has a puddle.

Double hearing protection at all times.

I think the spec when new for oil use is 1 gal per 10 hours... no joke.
I add a gallon every 1000 miles or so, this engine seems to be in decent shape.
