I was completely wrong. Every one of the multifuel injection pumps uses the exact same camshaft: SH9036A. However, it does appear that the plunger diameter of the hydraulic head varies. AMBAC lists the diameter for many heads but I can't find any information for the multifuel heads.....

Why do you believe this will shorten the life? This is what the manual states is normal/ intended operation? Functionally, the battery equalizer is like any other DC-DC converter with the difference that the output voltage is exactly half of the input. As long as you are not exceeding the...

Just a guess, but I think it is far more likely that the LDS injection pump cam has a faster rate of rise than the LDT/ LD. Do a google search for this and you will find a lot of information on this topic. The fueling rates for the different pumps can be found in TM 9-2910-226-34.

In stock, 134 hp, the EGT is quite low. You need to understand that the multi has 134 hp because the design intent was to replace a similar horsepower gas engine. While the multi is not a "great" engine, it is also not as bad you seem to suggest. Turned up to LDS power levels, the multi is...

The multi, turned up to LDS levels (very easy to do) is comparable to a non-aftercooled DT466. I believe that all of the the higher horsepower DT466 have aftercoolers and you are wasting your time not starting here.

Not gonna happen without destroying the engine first.

Assuming you meant 40/50 weight? I read some anecdotal information on ATHS that the engine oil really is better than gear lube because it flows better at lower temperatures. NO idea if this is correct...

Yes, I enjoyed and tinkered with it for several years with the 331 and 400 cubic inch gas engines. My brother had an M52 with the 602 continental. A nice truck and engine, as well.

I love the old gasser trucks. However, there is little market for them and, if you put money and time into one, you probably won't get it back out. Rare does not equal valuable. I'd rather see someone make a truck into something usable and cared for than rot because nobody wanted it in...

What is the size of the air filter opening? 4" ?

The cylinder is off of a 5-ton. The ball pin is from a 5-ton; turned down and shortened to fit the deuce. A local shop fabricated the steering arm (4140 prehard). The cylinder end is from a Ford tractor. The hoses/ fittings came from NAPA.

See pics.

I got 62k miles on my dodge before I had to replace the VP44. At least it was easy to replace. I think that the Bosh/ Multi works VERY well together (starting and running).

Only because it spins at a higher maximum rpm. Has the same output at sane rpms.

Reread post 71 where I said that your analogy was OK.

No, go back and reread your book or do a google search. I'll make it easy for you. From Wiki "Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the...

Your analogy is OK but Ohms law is actually V= I*R.

47 in Hg = 23 psi. Get the HP48sx calculator for your android phone. It has all of the conversions built in. Who said that they didn't make much boost?

Picked up another manual on the D4800 series. One table in particular has some interesting info on EGT: 1200°F exhaust at 0°F ambient. Quite a bit hotter than I'd have guessed. Note that this would increase proportional to the increase in ambient temperature. Also lists cooling airflow...

No, it was first a tactical engine developed in the mid 50s. The use in a tractor came decades later.
