Nice. I need the 4L80e in my 1031 since it is quite gravitationally gifted at 8700 pounds with all my tools. Trying to do 65 leads to overheating. The OD will drop the engine speed to 2000 rpm, meaning less heat to the coolant and more to motivating. For the record, the brake specific fuel...

Interesting solution. The rear pistons have looser fit for this very reason. How much flow do you get through this small hose?

Aside from a few simple tools, this seems possible as long as spring tensions are not upset. This means leaving the leaf spring in place.

No leaks from the IP. Only has the throttle blip dying problem from the idle speed governor. I bumped the idle set speed and can live with it but this isn't right. From what I have seen, the only calibrations are with spring tensions. It really is a simple pump, using charge pressure to vary...

Well, there goes my plan. The IP on my 1986 M1031 has the low speed governor retainer issue. It dies when the accelerator is blipped.

If you post a location, you might find a fellow member who can help you in person.

Road diesel often has a few percent biodiesel which dramatically increases water dissolution in the diesel as the fatty acid methyl ester acts as a detergent. It is resistant to filtration, salting out (adding brine to an organic phase to remove water) and drying agents. The only way to remove...

Yes, vacuum from this pump will actuate HVAC controls. These use very little and the pump has sufficient capacity barring leaks

Me too. Next year will be different.

I would recommend stable fuel like jet A or canned kerosine. Still the best storage is weekly running to operating temperature and monthly load test. Keep the fuel tank full as temperature changes cause air movement into and out of the tank. The air going in is humid, this will condense. You...

Great idea.

Engine oil has the heat of combustion, transmission heat comes from converter slip and pumping losses. The indirect injected engine of the CUCV means less piston heat but it still gets a good blast of flame from the precombustion chamber. Gasoline engines have uniform heating of walls, head...

Another reason for the non release is this vehicle was only in US Army service while all others were DoD. Several requests have been made through FOIA channels. The Woodward manuals are public release. But they are more general and one has to study the systems to correct install issues. The...

Check the sealing surface on the axle for the inner bearing seal. The M51 series had a replaceable bushing as this area wore rapidly due to abrasive. I remember they needed heating in oil to install.

The TMs have not been released to the public as one variant of the M1031 is the EOD variant with restricted radio equipment installation. On a side note, the governor on mine is now working properly. The throttle actuator had been installed incorrectly so it couldn't open the throttle...

Commercial bio is tested for corrosion, free alcohol and fatty acids plus oxidation resistance. Free waste triglycerides are quite resistant to transesterification. I would rather pay for good fuel than rebuilt fuel system components.

Even with belt drag, it is more like 5 HP at max speed. The fan is clutched so it only engages fully at high temperature.

Why? Made from waste oil, it has poor shelf life. Unless you get free waste oil, you will not save money. Even 5% bio has a poor shelf life.

My latest injector pump issue started with late injection symptoms and ended with the drive key broken. The key showed signs of fretting wear prior to breaking.

Very nice idea. I like fabrication but something commercial off the shelf is a time saver. I'm looking into it..off to Rock Auto..
