THANKS!!! That is just what mkcoen needs!!! And something I can build for him, that way he can tow his M37 easily. 5/16" end plates, looks like there is a flange on these. Probably A500 tube and A516-70 plate would work. I would want more meat around the top bolt holes, not an issue as I...

I doubt the electrical connections are potted so there will be some leakage current through the legs. AC in water just causes heat, electrolysis cannot happen. But you could have a potentially LETHAL combination there if the generator is grounded and there is a fault in the breakers. You...

Everything unscrews. Front light bezels are attached with 4 screws, two through radiator support, two exposed. Torx screws. Side markers are attached with two screws visible in the lens plate. Sounds like you have a chaffed wire.

How easy does that fuse (the one that keeps blowing) go into the block? Even clean contacts can have high resistance if the spring tension is weak. They need to fit tight, so tight they are hard to pull bare handed. If the resistance of the contact is high enough, it will overheat the fuse...

Power to turn over the engine remains the same, with two in series, current is halved for the starter. The glow plug draw is the same, half of that power is dissipated on the resistor bank in the 24 volt system. Yes, use 2 batteries which is a tad bit more efficient since the 1200 watts...

Consider an electric water heater as a load bank. You can trip the breaker off when you need power for the HVAC, then turn the water heater on when load is light. 4500 watts is a good load on a 003 (typical water heater). On wet stacking, my step son was restoring a M1009 for about a...

Disconnect the line from the pump and hook it to a gauge while idling, should maintain 18" of Hg. Likewise, with it hooked to the transmission vacuum valve on the injection pump, test with a tee in the line for the gauge.

You towing it home tonight? I might be able to give you a hand opening it tomorrow.

They are standard #8 refrigerant o rings which are Viton.

Also, could be JP8 which cannot have any biodiesel in it, unlike commercial D2. Biodiesel has a higher affinity for water, allowing it to become cloudy after a year or two. This is why you should rotate diesel stocks. Have two drums, one you fill from 5 gallon cans you purchase when filling...

And the low oil pressure safety switch can easily be tested. 1/8 pipe threads, hook it up to the output of an adjustable air pressure regulator. Then hook an ohmmeter to the two connections and slowly raise pressure while looking at continuity on the meter. Should be 12 to 15 PSI when it...

The 40 ohm ballast resistor isn't part of most overhaul kits. Some rebuilds don't have it. I just did mine, using the old resistors and the old capacitors as they are easy for me to test.

Tension gauge? Can you turn the alt fan blade with thumb pressure? Then it is either loose or incorrect pulley. The bottom of the belt should not touch the pulley bottom, that is how the belt wedges into the pulley to get friction to turn. But yes, new/rebuilt units are known to fail. It...

Sounds like the pulley is slipping on the rotor shaft. Not belt slipping on pulley, as you mentioned the belt tension. Why? Alternators vary the rotor field current, this varies the strength of the rotor magnetic field. As these alternators have claw pole pieces, the AC waveform is less...

Rotate fuel is still the best.

Sounds like oil pressure safety switch. What does the gauge read? If over 15 PSI, short the two connections to see if this works around the problem.

Yes, I thought the 1031 had a factory starter since it only had 9009 miles when recovered in 2012. It was missing the pinion retainer which caused it to go over center and stick.

The wire from the rear battery negative is the same as the front battery positive, it runs to the diamond block left of center on the firewall, this is the 12 volt bus for the majority of the truck's electrical load. Only one fuse on the block is 24 volt and there is a 24 volt line running to...

That is EXACTLY how it looks with my far-sighted eyes :-?. Sounds like someone installed a pressure switch, a no-no as they tend to fail with boosted brake pressure. Check the front cross member, its back face. That is the disc/drum brake pressure proportioning valve block location and most...

Yes, they are the same alternators but different mounting hardware.
