Great looking engine you made! And performance described is very impressive. Also many thanks for the education. I belive the most people who uprade their vehicles above the stock performances do have plenty of secrets to keep. On the other hand any hobby is fun when you share your emotions which in many cases mean sharing your experience and part of know how. I personaly don't pretend on spying the rocket science. My goal is making a truck able to some grade of streets hot rodding. Something able to compete with modern cars producing sound and a bit of smoke at the time. Sure up to reasonable roads speeds. To me it seems the 1st matter is higher revs which would allow you to shift less and prolongate accelerations. I have no idea on how many HP is required to accelerate efficiently probably the more the better but E9 engine alone fitted in a single tractor could be quite "noisy". Actually there are no such vehicles in my country so seems like no need in a really high $$ project. Anything outperforming an avarage modern truck would be good for me. So as long as I asked above the high revs I would like to know (a bit) above the inside the engine components. Do you need special pistons and rods or the stock parts could survive the trick too? Any difference in the valve springs? Is there a reason to machine the sleeves for larger bore? My block needs total rebuild no doubt and keeping in mind current costs of stock parts even PAI it seems more reasonable to custom order forged pistons which wouldn't be terrible expensive overhere. Doing that I would order them a bit larger OD and rebore old liners instead of bying a new set. That's just thoughts on the pre-plan so far no more. Using old pistons with new sleeves and new piston rings would work for me too since I don't plan highway milage. Very interesting info on the fuel pumps. From what you posted it turns out any inline pump is at least 12mm barrels. Do you mean 900HP can be achieved if the pump is set for its maximum stroke delivery? I sure would like to learn that figure and 520HP stock stroke delivery either. No strong need to post it now and here. Governor tinkering reason is clear to me. Current way of things tells me that I supposed to dig into E6 Ambac governor myself. And if E9 one would be next in the raw it doesn't seem as a nightmare. At least so far. Is the 13mm barrel pump a stock part to any Mack engine or plungers off another Bosch unit should be used?

Unbelivable ! ...

Those front 445 wheels seem huge. How do they correspond with the rears? I mostly mean the look. You put 11R22.5 in place of 11.00R20 tubes there right?

Drool, drool, drool !!!

Sounds like a cool (oh sorry, hot) deal on that Bosch pump. Renault Magnum was a pretty common truck in Europe but was taken off the production a few years back so I suppose they will leave the highways soon. Actually many trucks already moved to cheaper regions starting from Poland and further East. Also the matter is high costs on the rebuild parts puts many owners of the V8 models to decition to change the truck or an engine. So European E9's has tendency to dissappear in the distant future. Speaking the inline pumps I belive it's quite common part on European spares market. And V8 style is no doubt hens teeth. A question. How are you going to get 800HP (if not a top secret stuff) using 520HP pump? I grabbed a giant locally a couple months back. Poor shape but cheap. Going to ask a few questions but the project is on a back burner so far.

What is the size of the front tyres? Are they 385 or 425? I hope I will share the reason I ask the other day

Keith, From my understanding there was a filter can installed indeed but on T107 series transmissions. T2070 etc didn't have any filter installed, just a small pressure governor (limiter?) fitted on the (rear?) top cover. Cool looking truck you catched. Congrats!

The wheels were 12x24 all over the truck and as long as I remember the rear tyres were made in India. Good point about the tanks. As I figured the reason was not really large distances in the country but the cost of diesel. A couple months back I spoke with Iranian driver and he said me that fuel turns out cheaper than bottled water there.

Looks like an L-model radiator assembly to me. A-models seem having flatter front end like B-models do.

I have a 1945 Mack truck (tandem rears) and its bearings designed to spin on grease. But there are additional seals in the jack shaft flanges to separate gear oil from the bearings. So my suggestion is your wheels spin on oil. Or maybe the outer seals also took place and someone removed them in the past. To be sure I would look in a E-model parts list or maintenance manual for the hub assembly design.

The link works very well. Once again thanks for sharing those beautiful show pics.

Nope, a different origin this time. But the optional equipment is nice.

Yup. Definitely.

Actually the truck in the picture was the 2nd generation Superliner with older hood installed. So my guess is the doors went off the same early truck as the hood. Funny if there was the only unit painted that way and its hood ended up on this truck.

Good points. Another idea is to put a thread in the Firetrucks section of the site with a question of something like CF automatic tranny issue. Plenty of former or actual firefighters pay attention to that particular forum and if there's any special switch put by means of pump operation or so the answer would be right on a surface.

Seems making sence for a RL.

Speaking the automatic transmission I would suggest two possible matters of the issue. Worth to point out I have never dealt with hydromechanical units on big trucks. But rebuilt them on Mercedes cars of 70's and 80's years. The principles seem the same. The transmission has hydraulic "brains" - multi-valve hydraulic control unit which directs oil pressure to some shift cylinder or another which makes gear change. There are two main parameters the tranny figures out when to shift (or not to shift) - vehicle speed and the throttle pedal position. The logic is simple. More speed and reasonable or low gas - upshift. Low speed with plenty of gas (load) - stay in gear or lower it. Higher speed - upshift. High speed and full gas - downshift for maximum acceleration - "kick down". Ok, the tranny knows both those parameters by some way. The speed usually measures inside the transmission buy special valve connected to the output shaft. You should be an automatic transmission rebuilder to get to it to check or fix if needed. Gas measure provides much more simple usually by a linkage or a cable which connects vehicle's throttle linkage and something sticking out the transmission. Usually a small lever or so. You just observe the tranny for something that connects it with the gas control and operates together with it. The important for the matter point is if the throttle is settled for "full gas" for the transmission (jammed or wrong set linkage) the tranny would suggest it as a full load. And it wouldn't upshift staying in the 1st gear. A variation of the issue could be if the tranny is equipped with special "kick down" control. In cars there usually is an electric switch put below the throttle pedal. So when you press the pedal full way down the switch connects its contacts and supplys electric power to a solenoid in the tranny. The latter opens or closes certain oil passage in the control module (the "brains") and orders the tranny to downshift. Usually if the spoken switch gets short connected (jammed) the tranny starts from 1st gear and continues driving in it no matter how fast you try to go. My suggestion is a big truck or a bus may have a dash switch or a knob for hand operated kick-down so you should watch for anything like that in your rig. All written above could be count as "simple reasons". If you found nothing of those another matter could be the brains - hydraulic control unit. It's quite complicated assembly mounted inside the transmission and can be accessed with the lower (oil) pan removed. You need a rebuilder to check it out of another unit to swap in in a hope for correct operation. In some cases no upshifting can be determined by incorrect operation of the speed valve. Usually hydro-mechanic tranny has a few plugs at the outside to connect a check oil line and pressure gauge. It allows to control the main operational pressure (no vehicle move if it's fail) and that "speed" or the output shaft spinning pressure (every control signal in those trannys is a pressure since it's hydraulic not electric). I have such checks done using just a common pressure gauge and a hose with a fitting suitable for the tranny connectin. But I had a repair manual for the particular unit I dealt with. All in all you have good chances with finding the "simple" reasons and if no my next step would be a search for an old automatic tranny specialist. My guess is a car tech could also find the issue if at least has any interest in doing that. Vlad

No words, just emotions!

Big difference between European and American gearboxes is the first have synchronizers. Those allow you to force the lever slowly and after waiting for a bit of time the traction eliminates the speed difference between the engaging splines. Theory tells this style of the shifting mechanics is less reliable since the weakest point in the tranny is synchronizers. In practic it looks to me like good quality units work about forever.

After getting upset from hearing trrr for half a minute you push the lever stronger and get it in

Paul, sounds like your tastes are simple I wish you to make all your wishes true but not really soon with that particular one. Here we doing well with Covid as it looks to me. The country functions and the most people don't really care about the virus to the moment. Acually there were about no limitations just a week back excepting wearing masks when inside public buildings with all restaurants, hotels and stadiums open. This passed week some increase of the illnesses occured so the government put some back and started forcing the people to vaccinate. It's not a must to every citizen so far but they turned it out you became a must for many professions such as medicals, transport, sales, food and many others who supposed to get in contact with unlimited amount of people. I personally haven't got the vaccine so fare because I'm sure I passed through the deciese about a year back. Didn't make the test but the sympthoms were very meaning. On the other hand plenty of people I knew took the vaccination (Sputnic-V is used here and it's free) and nobody had troubles after that as long as I heard.

Great!

That's really nice daycab F-model. And that NO PARKING sign definitely takes attention.

Mike, have you grabbed it? If so it seems like a great addition to the collection. I also miss the show and nice folks in PA. The only good thing I feel the isolation is an excuse for long unfinished projects. Less travels mean more shop activity. But our hobby is nice due to multiple sides. Like a diamond Hope you had a lot of fun at the show.

Very interesting to see the environment you blokes live in in person. I keep attention to what you post and tell about the brown land but seems you do never understand before see it by your eyes. I hope this new reality will calm down at a certain time and the borders get open. Thanks for sharing with us your part of the world.
