Fuel tank cleaners
BOBWhite replied to hicrop10's topic in Antique and Classic Mack Trucks General Discussion
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.

Diesel draining back to tank when parked up over night.
BOBWhite replied to Mackman686's topic in Engine and Transmission
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 -
Do newer air start systems have a separate tank for lubrication? Since the return fuel side has to be completely sealed up on some engines and diesel's not as good of a lubricant anymore.
-
Interesting. So air start systems have a solenoid activated valve that sends air to the starter? Did they ever make them with a manually actuated lever or valve that you could use if you really hated having a good battery? I never have been around anything with an air starter but sure have thought about getting one for the stuff we only use once or twice a year. Beats hauling battery's and cleaning connections in a hot shed.

1941 Mack ED firetruck
BOBWhite replied to 41mack's topic in Antique and Classic Mack Trucks General Discussion
You said it has a continental engine in it? After thinking about it some I remembered that a lot of the Massy Equipment used those engines. I've seen some in combines so you might try there. Best of luck -

Im definitely tuned it. Thats a cool rig! Sends some pics of the engine. You might be able to bring it back if nothings cracked up too badly. -
Chrysler V8/R Model Bellhousing
BOBWhite replied to PMC's topic in Antique and Classic Mack Trucks General Discussion
I'd just assume that it was a different transmission (not a mack) for gas models. But it could be a Mack trans. I think they had the standard SAE 11 bolt pattern which I'm assuming Chrysler would provide the adapting stuff for. Just guesses though. Very interesting topic. -
Hopefully more trickle down to the US. And what's the deal with the Michelin man on the top of the truck in the 5th pic?

Hi everybody, new here and just purchased a Mack Quantum
BOBWhite replied to Gorilla's topic in Introduction Forum
That thing is so cool! I'm a big fan of the MH Mack but they never made a low cab forward version so I'd guess this is the closest thing to one. I have a sneaking suspicion that the frame is a Renault. Looking at this form here: It looks like the air compressor is almost touching the frame rail which I don't think the CH or R frame is that narrow. Could just be that they put the engine way low down between the frame rails but what do I know. -
Something simple like valve guides? Could be anything the more I think about it. Can't be too picky with E9's these days though

"Bad" driver and the B Model
BOBWhite replied to D2Denny's topic in Antique and Classic Mack Trucks General Discussion
Yeah that was recommended to me too: Why'd they have the make the B model driver the bonehead? -
-
Ok I think I know where you're talking about. At the end of the road there was a big gate so past that musta been where it was.
-
I think you're correct. I went looking for it today and found a scrap yard around where I think it would have been. Found a cabover Freightliner in sad shape but that's it.
-
Hardly any boost and it won't make much noise. Depending on the model you should be able to manually move the actuator to see if it's stuck.

The man who sold more orange Mack hats than anyone Johnny Hardwick passed away. He played Dale Gribble in my all time favorite cartoon King of the hill. I don't know if King of the Hill is popular in other parts of the world like Australia, but it really shows average American life better than any other animated or live action show I've even seen. We really lost a legend.

Well I had no idea that tilted engines were as common as they were. They seem to have fallen out of favor in most applications except in busses. I don't envy the folks who have to work on these but I do envy those like Paul who got the Hemi inline 6 down in Australia...
-
I saw this today on marketplace and I've never seen an engine tilted this way in a semi. I knew that some of the 1990s and 2000s sterling trucks tilted there engines a bit for hood clearance but nothing like this. I'm guessing they could put bigger engines in this way. I knew Dodge liked to slant there engines but I had no idea they did it to other makes as well.

Hey nice truck! Even better if it has the 300 6 You'd probably only get about $500 for it anyway so what's the point of selling it. I got mine for $800 am I'm getting every penny I can out of it.
-
lol that's video is awesome! The "tough guys" around here still do everything the "old fashion way" and wind up getting mangled. But the fat chicks love it! You guys down there in Australia have had it figured out, we just like wasting everyone's time playing cowboy. One LandCruiser should do the work of about 10 guys on horses.

At least some of the 12,000 trucks are going to come up for sale flooding the market with cheep equipment. Wonder how long we're going to keep seeing these old yellow trucks on the road. Kinda sad
