67RModel

The E9 was probably a big deal back in the day but honestly is not all that impressive by today's standards even when compared to a "puny", modern 12 liter engine. The E9-500 didn't even make 1700 ft*lb of torque. Torque is a very arched curve peaking at 1650 at 1400 rpm. An MP8 has constant 1860 ft*lb from 1100 - 1400 rpm. and The MP8's 505 hp is almost constant from 1400 to 1900 rpm. The E9-500 is only making 440 hp at 1400rpm and gradually climbs to a peak of 500 at 1900rpm. All else being equal an MP8 would easily out pull a stock E9-500. and a 605 X15 Cummins would blow the doors off the truck with the E9. My guess is keeping the MP8 running and out of the dealership service department would be problematic though.

Harbor freight makes one that works very well for like $35. It’s nice to have around. It comes with the reflective tape. https://www.harborfreight.com/digital-photo-sensor-tachometer-66632.html

Please understand I'm not suggesting 300,000 illegals each year is an acceptable amount. I would say even 1/year is an unacceptable number while also understanding that would be impossible to achieve. All I'm saying is if this person truly did make the claim "the population of Pittsburgh/day" then he should not be taken as credible because the numbers don't lie. 300,000/per year is much more believable but grossly unacceptable.

Who is Dan Bongino? He sounds like a lunatic. The population of Pittsburgh is 300,431....Call it 300,000 for simplicity. 300,000 illegals crossing the border every day amounts to 109,500,000 people every year. The total population of this country is 332,000,000. Are we really to believe the population is growing by 32% year over year? It took since 1978 (45 years) for this country to gain 109,500,000 people. He had to have meant 300,000 total per year

I thought about this at one point too. These engines are governed at 1750 for fuel consumption / noise driver fatigue reasons. If you could wind them up to 2100 you could catch the next gear at a higher rpm....say like 1200 rpm. The difference in horsepower between 900 rpm and 1200 rpm is about 65hp, which is not an insignificant amount. Another option would be to install a Jake Brake and shift using the Jake. I think this a better option since a Jake Brake is a much more desirable thing to have than a 2100 rpm governor but obviously its much more costly. I guess you could have both as well. The attached picture is for a Maxidyne E7-275. I assume the numbers are similar for an E6....

I would say yes depending on the application. Its the Mack triple countershaft design so its tough as nails. Able to take a fair amount of abuse. Very simple design as it does not have any air actuated range selectors and valves to give you any grief. Just a lever and gears. If the truck has 11R24.5 drives it will do 70 at 1643 rpm and 77 at 1800 rpm. With only 6 gears the steps between gears are large so it wont maintain speed on large, long hills as good as a 13 or even a 10 speed would. That is just the nature of fewer gears....You need to let you road speed fall almost twice what you would in a 13 speed before downshifting to the next gear. I see your in Illinois so its probably a non issue.

Looks like the information you need is on page 4-37. Not too many people know anything about Midliners.....they are beyond obsolete. Hopefully you don't need parts for it. Good luck.

Looks like Houston, TX judging from the sign and phone number in the background of the last picture.

I can't say I know. I just know what a true 30-40% grade looks like and I would in no way whatsoever be wanting to be repeatedly starting and stopping on it loaded down with any amount of weight. I imagine you could get by with that setup for a while or a couple times but I don't think it will hold up long term. 30-40% grade is astronomically steep and I seriously doubt your setup was "designed" for that amount of driveline strain. Another thing to think about is what type of road surface will this be. There is a big difference if its soft soil versus an improved hard surface. And like I said earlier I would be concerned about starving the engine of oil depending on which way you are facing and how long you would be in that position. I'm sure its published somewhere the maximum recommended grade or angle its safe to operate one of these engines. Ideally I would think you would want some variety of Allison automatic and planetary reduction drive axles but that is beside the point. Only one way to find out....

Mack top loader axles are a double reduction design. Basically the torque multiplication is done in two steps rather than one. Much less strain on components and less of a chance to break things. Much more desirable for what you are attempting to do.

I foresee lots of driveline abuse and broken axle shafts or universal joints. Do you understand how steep a 30% grade is? A lot of people would struggle to walk up a 30% grade. Canton Avenue in Pittsburgh is often cited officially and unofficially as the steepest public street in North America at 37% grade. I have driven up and down it in a Honda car and it was scary quite frankly. Plus the top 2/3 are made of brick. Technically your not allowed to drive down it only up. I could not imagine driving up that hill in a truck loaded with 4000 gallons of water. Let alone stopping a 4000 gallon tanker on that hill and trying to get started again. If you did you would never shift out of Low gear until you reached the top. Forget 400hp. What you need is lots of gear reduction preferably planetary reductions at the wheel ends. Are the axles in the truck Mack top loader double reduction or conventional Meritor axles? I honestly would be worried about starving the engine for oil at such an extreme angle. I'm not familiar with where the oil pickup(s) are on these trucks but depending on where it is you might be sucking wind either going up or down. https://en.wikipedia.org/wiki/Canton_Avenue#:~:text=Canton Avenue is a street,street in the United States.&text=Canton Avenue is 630 ft,feet (6.4 m) long.

All kinds. Depends on that you are trying to do with the power and how much power you need…. https://www.munciepower.com/software/power?utm_term=muncie pto&utm_campaign=PTO+-+Muncie&utm_source=adwords&utm_medium=ppc&hsa_acc=5308245189&hsa_cam=2006524944&hsa_grp=70842579829&hsa_ad=353523123774&hsa_src=g&hsa_tgt=kwd-351210315807&hsa_kw=muncie pto&hsa_mt=b&hsa_net=adwords&hsa_ver=3&gbraid=0AAAAADdCVMj0jyimqXMamuvziUxfLcn5F&gclid=Cj0KCQiA6vaqBhCbARIsACF9M6md9-iXKogEgZu_486TLcXbMEUE_UOBSXEwrB2DyAkfZS_3z93CPigaArROEALw_wcB

It was for sale on here a year or so ago

I have noticed what your talking about when using a smart phone. Get on a real computer and the web pages are totally different and have all the information and user interface features you could ever need. The "mobile friendly" versions of just about any website is 100% worthless. I hate looking for anything with my phone. It is an absolute last resort option.

I dunno. I was exporting two DMs to a fellow in Nigeria and it didn't seem a big deal at all. two notorized bill of sales signed by both parties is all that was required. I was also going to chain down another complete engine to the frame rails of one of the trucks to save on space. The deal ended up falling through due to shipping costs but the process itself was suprisingly easy. I imagine if your just exporting parts it would be even less red tape. Paul, you should really look into flying into the East coast and finding a nice drivable Brockway. Drive it to the Canadian Rockies. Do the horseback thing (I would ask for a mule. No horse can match the comfort and sure footedness of a mule). Then drive the Brockway to a West Coast port for export. If Brockways are as rare as you say in AU then this is your chance to bring one over. Just a thought.

Saw this listing on FB Marketplace. No affiliation. Thought is was interesting someone had bought and assembled a glider kit in 1998 and left it parked in a barn until now. It looks to be as "like new" as you can get. Even though its 25 years old it will probably operate without much fuss for another 20 years. The price seems high but when you consider a brand new triaxle dump is now over $250k and at least a 6 month wait to get one, it might not be a bad deal at all. Interesting unit. https://www.facebook.com/marketplace/item/363122179483294/?ref=search&referral_code=null&referral_story_type=post

What is an H613? Single axle? Engine? Etc...

I always suggest to guys that own these Renault trucks to find and call a dealership in France. My guess is there are a boatload more of them over there than here. I wonder if the parts are still available through the original Mothership?

Supposedly you can still get them through Mack but they are $6000......No joking. See below topic from a few weeks back:

I also have a picture of the first International Loadstar pictured in the article. Its from the Iowa 80 Museum. I wonder if the differential is bolted directly to the output yoke of the transmission. I thought it was a pretty strange unit, which is why I took a picture of it.

Not too long ago I saw a wanted add posted for an original Mercury sleeper. The guy said he was willing to pay up to $5000 for one. My guess is $2500 and up depending on condition. I don't think in this day and age you would ever find one advertised for sale for less than $2500 - $3000. I would be curious to know what a brand new one costs to get built. https://www.facebook.com/MercurySleeperCo/

Yea everyone wants an original Mercury sleeper and they are nearly impossible to find now. I think there is an outfit in Michigan remaking them just like the originals. I think you can find them through Facebook. But like anything everyone wants an original one. They are aluminum so as long as they don't get smashed they are usually in decent shape. Yes the interiors get clapped out by rodents and deterioration though.

Obviously not a Mack but given how scarce good condition Diamond Reos of the White era are I figured I would post it. Not to mention it has an unobtanium Mercury sleeper on it that everyone seems to be nuts for. All for $4500. I would say that is a heck of a good bargain if she is a runner. To bad its not closer to me or it would be in my barn already. I always have had a soft sport for the Whites, Autocars, and Diamond Reos of this era. Not mine just passing along for anybody that might be interested. Anybody in the Denver, Northeast Colorado area???? https://www.facebook.com/marketplace/item/876572523826361/?ref=search&referral_code=null&referral_story_type=post

Your not missing much. Its dubbed "social media" but actually encourages people to be less social with one another. The Marketplace feature is the only useful part of it in my eyes. Everyone has moved to Marketplace to sell whatever they have to sell. Craigslist and the like have essentially disappeared and are no longer useful because everyone has gone to FB Marketplace. In a good way I think it encourages a lot of people, who inherit or otherwise come to have what they think is "junk", list it for sale. You can essentially find just about anything you want on Marketplace. If somebody is selling one it will eventually pop up on there. Its actually crazy how many vintage and antique Mack and other brand trucks are on there. I only every try and post the "special" ones but its full of old iron all over the country. I don't have Facebook but even if you don't have it you can search the listings through SearchTempest.com or other sites like that. If I find something I am interested in I have to have my wife contact them for me to get a phone number since she has a FB account.

The G model looks like a truck from 1979 not 1959. I wonder why it had such a short run?
