Not much more flow you can get out of an only 2 valves per cylinder although I've heard some say they pull just as good or better than the later 4 valve E6. More fuel will just add to EGT and smoke out of exhaust. Plus the bottom ends of the E6's are made only as strong as they need to be and not much more. I've heard of crank shafts snapping.

Tread lightly when tuning an E6 especially a 2 valve.

Yep more pictures. Its probably an early E7 if it's not an E6. Every E7 I've seen has the Bosch P pump and this doesn't look like a P Pump.

Hard to believe that truck is the same year as my IH Transtar. Looks like an old school truck in the days of old school trucks...

looks good at cleaning carpet!

Anyone know if tip turbine engines were ever used for marine use? I would think that an intercooler on the engine would be nice on something that doesn't have a traditional radiator like in marine or irrigation motor use.

This guy has been doing some great video's on Mack engines that I thought I'd share. A whole new generation now knows about about the tip turbine engines.

I wouldn't order a truck without a manual transmission unless I had to. And if I had to pick an automatic I'd try and pick a REAL automatic like an Allison. Automated manual transmissions might be more efficient but with the complexity I don't see how they'd make sense in the long run.

I've heard that about the Paccar and Cummins engines. Choked up on the emissions stuff all the time its not hard to see why

Not going to make it to the main event but I went through Pratt and took some pictures while they were setting up the show. Not much to see but I sure do love this B model! Hope I can meet the owner someday.

I think either Oliver or maybe White also used Hercules diesels in their tractors. I wonder if the manufacturer casted the manifolds with their name in or if the manufacture did. Did someone in the past do this just to screw with us?!

Who wants to know??

Was Mack still producing railroad equipment as this time? Maybe it came off of some sort of yard shunt locomotive

Well I don't image anyone here would be going to a truck show in the middle of nowhere but I might take some pictures if I have the time and go.

This got me thinking, why don't more people buy these? A brand new Isuzu F series comes with a 6.7 Cummins and an Allison transmission so you could make a heavy duty work truck without having to buy a dodge! You might even be able to snag one with a manual transmission. Sign me up! I'd put a bale bed and a caker on the back and have quite the cow rig

If you own more than one of these... I think as soon as I could walk I was toting one of these homemade air bombs around

Adding onto that what is the difference between a long shaft pump an a short shaft pump? Does the radiator sit closer to the engine on the B models?

Cool rig! Is it double or single framed? also what engine/transmission does it have? Welcome to the forum!

I use small to medium sized rocks from my driveway and shake it dry for awhile, then I use simple green or water to wash out what's left. Never had to do this on something bigger than a 15 gallon tank before though. I've had success with fuel tank sealing products before but I don't recall exactly what I used. I know it was the kind that you poured in then shook it around to coat the tank. I highly recommend using a fuel bowl if you're going to be using any old tank, especially if you've put rocks or bolts in there. There simple and cheep plus you can visually check for dirt and water. Best of luck!

I believe oil goes through the small tubes and the coolant surrounds the tubes. The oil first goes through the oil cooler then it goes to the oil filter assemblies. Heres a pic from the manual that shows each of the tubes. I think the tube you are referring to carries the cooled oil back to the oil filter assembly.

Mechanical drive is still more efficient simply because of the heat losses. Reminds me of the trend of combine harvesters in the 90s where most of the belt and chain drives were replaced with hydraulic or electric drive. Simplified maintenance was the goal but recently most of the manufactures went back to belts due to more efficiency. The real electric advantage is torque application, thats why you can use a smaller motor. Most of the power a truck needs is just to get moving but If you had an electric motor to provide additional torque you can get away with a much smaller and more efficient motor. Plus you can drive without the motor being off but you would have to figure some sort of electric power steering, AC, and air compressor drives.

I don't see how it would be any more efficient on fuel than a conventional truck with the loss of heat and everything. The regenerative braking capability's the real energy saver. I would use the traditional engine, transmission, drive shaft, and differential setup but have an electric motor act as sort of a carrier bearing between the transmission and differential. Then put a small Detroit 50 or other similar sized engine and have the electric motor assist when needed for extra power. Hopefully sodium ion battery's get cheep enough that I can do this someday.

Welcome to the forum! A clear fuel line can be used to test if you have air coming in through the primary side. Could be a check valve in the system but I cannot say for sure. Definitely check all the return lines too. You said it was a 2 valve? In America the 2 valves were mostly fazed out by 1986 but maybe it's different elsewhere. Nice looking truck either way
