What a great look of the roads was in those days!

Now the times are different, different rigs.

Thanks the great for pictures mate

Congrats on the purchse!

The truck looks cool and definitely has plenty of potential!

The configuration is my taste's best. If I could chose a B-model to have in collection my top preference would be tandem B-75 with a B-model cab and factory V8 Mack engine!

Pre-war Mack BG (or BJ or so) was interesting and in restorable condition. At least as it seemed to me by the pics. Sure you can restore the most any truck no matter how hard it was ruined, just depending on the efforts and expences. But particulary that rig is quite rare and of not very complicated design.

Mack changed the crank and other heavy loaded parts when they went to Maxidyne from ENDT673. Which was of Thermodyne family which was introduced to the market in 1938. Much higher torques produced by Maxidyne required much more strength of the engine components. I don't know when Econodyne was put on the scene, probably is was a kind of mod of Maxidyne engines but with more common fuel settings. 

The difference was mostly achieved by different governing in the injection pump. Thinking about the shapes of the governor inside parts it looked to me like the governor had ability to push fuel rack at low revs so the engine would pull. Ok, I'm not almost sure on the physics but if you want torque, actually - forse, for a vehicle to pull load you need fuel to be burned. There's no magic in the world. So that fuel must be delivered into the cylinders. And if you don't tread the gas pedal hard but the truck pulls well it means fuel is supplied in sufficient quantity some how. To me it seems the governor is making the trick while you hold the go pedal relatively steady.

The second big point (mentioned in discussions regarding Maxidyne engines) is the turbo. Definitely if you want to burn fuel you need air. More fuel - more air. So turbo must do its job. It was said Maxidynes had different turbo than Econodynes. Possibly. As of me I'd like to know what was principally different in them and how big that difference was. Since I read someone's posts from time to time when a certain common turbo was installed onto Maxi engine and against expectations of experts of the community the truck gets driving fine.

Injectors could be different (and they're different) since the combustion process goes at different revs so optimal spray pattern is different too. Which could be achieved by different crack pressure. There also could be difference in the shape of cams of the pump cam shaft. Initial plunger speed may be different in different engines and the injection stroke may be longer or shorter providing different intensity of combustion. Timing angles are items from the same basket. So when you want a certain engine to be set for a certain specific performance many aspects may be performed.

Our Cruiseliner has an EM6 300 HP.  I thought I read somewhere on BMT they went to 350HP or am I mistaken?

Mack went up to 2 valve E6-350 indeed. But those were not Maxidynes. Low torque curve was sacrificed for higher HP. And a bit higher highway fuel efficiency. I have that kind of engine in a MH of 1984.

Hi Vladislav,

Yeah not much we can do about the people in the world who stuff it up for the rest of us!! yes the twin steer axles and tandem drive axles (8x4) is very very common here and has been for a lot of years in every part of road transport with being able to get a decent payload with axle weights. that MH was on logs and towed a 3 axle and or a 4 axle trailer pull trailer which is still a combination that is still an everyday use and in the last 10 or so years they've added a 5th axle to the trailers for more payload.

cheers Keegan  

Two thumbs up!

Sorry to hear. Not only the trucks are getting older. Hope and wish the fix will work out well.

Thanks for posting the show pictures!

Looks like the day was great.

That V12 RS is impressive. Wonder how many were built?

And it looks like a Big Horn was parked to the right of it, no?

And... I re-read the whole thread - was that MH with V8 really assembled as late as 1999?

Good luck on the progress!

We all sure would like to see the final result.

Tom, did you share the story of purchase of the CH? If yes where to look at? I remember your affairs regarding that green International. But almost missed the Mack party.

Thanks for the cool pictures Tom!

That very first one... Looked very much like you came to the show in the CH... And than Zina accomponied you driving that blue KW

I see the jumper wires now, who knows what I was thinking! And everything would be 12 volt since both battery banks are grounded. The two solenoids are for key on and start. I've never been very good with these diagrams, at least there are no Diode or Resister alien symbols. 

 

Two groups of batteries in parallel. Each one conteins two batts in series. If they're 6V two bring twelve V. Almost as Geoff said.

Happy B-lated B-day! 

Seeing the picture I was sure for no less than a couple of minutes that's a scale model!

Ok, found much better pic. It was a restored British NM which was sold to Belgium. I took the photo in 2011. Don't know where the truck is now.

Thanks Vlad for your interest and suggestions.We made contact with a guy who works with fiberglass and he is making a patch panel and fitting it for us.He is very interested in helping us with the Cruiseliner....

Paul

I have two R-model hoods redone to the moment. And discowered plenty of old poor quality repairs in both of them. What I advise you to pay attention to is grinding the base material (the cab wall) mating area to clear solid fiberglass, with no restovers of paint or old filler, and arrange maximum possible overlap. For the patch I suggest you need no less than 30-40mm wide stripe of bare fiberglass to glue onto. Also the grade of degrease and dust remove needs to be a top and well guaranteed mixed components of resin or glue. These simple basic nuances play very big role since quality of the seam is responsible for not only the seam itself but also for paint works and all the followng final assembly works.

...And I'm way not too

Agree, not the best thing to do, but after miles of this, my patience wore thin.  Unfortunately with age I am not getting more tolerant.  And like my parents used to say back when .."kids these days!"

Agree, we are people, not made of iron. Just sorry to force you to confess you was not an angel that time

Today, that would nearly total a new vehicle!!  Crumple zones and all.  Door might not close correctly anymore??  😆 

 

Glad both walked away.

 

I followed a car of very young girls on the way home the other day.  25-30 in a 45 zone. She was just coasting and brake checking the line of traffic she had built up over the last few miles.  She made a right and I followed and rest of traffic between us went straight.  I had clear road and went around her quickly and then nearly stopped in front of her.  I flipped her off and then sped away. She just idled and I lost track of her. 

Either she was scared to be on the road or just screwing with rush hour traffic.  Either way, she got a lesson.

Larry, I'm not sure that was a good lesson. She sure should know that's not nice to be a plug in front of line of vehicles. But that would work if she's experienced enough to drive fast enough. But if she had been in her first days or a week in the street her goal might be keeping the drive at all and do not smash into anybody/anything. So seems the lesson could be of talking to her to drive fast enough if she could or if not than to stop on a shoulder from time to time to release the main flow. I'm sure in the most cases it's not easy to speak with another driver and explain things. So I usually just pass by keeping hopes the new driver becomes better soon enough.

In my experience I stopped a couple of drivers who was making some wierd actions, just came close to their driver door and in a calm manner spoke what I thought was not good and how that could be better.

Yes he sure is!!!! That was the Thanksgiving you spent with us, yes??

And I don't think you ever met Josie have you? (Extra Small) She is now 11 

I saw Josie at the Thanksgiving at you in 2018. You have mentioned the Extra Small a few times earlier in the forum posts so I knew of her walking over the world. Casey was really small when you met me and Ilya and took us to Macungie. That time he was taking his place in a kid's seat at the rear of your Silverado. And couldn't say a word than if I remember well enough. That was in 2013 so I guess he was 1,5 or 2 y.o. than. So surprizingly the life goes by by so big leaps and bounds at the time we ourself think and feel everything (including us) continue being the same.

I spoke with Ilya today, he's turning his 25 in a couple of weeks. Said about Casey's achievements. I'll send him a link to this thread.

And hope you're doing fine!
