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?

I think there is an ongoing "debate" or discussion as to whether or not the G model was a copy of the Kenworth cab of the time. Supposedly Mack hired Kenworth's designer and the two cabs ended up being mostly identical. (or something like that). The Mack museum even went so far as to research all their records and make a publication about it due to many inquiries on the matter. See below. I think there a few old threads here on the forum about it as well if you search. https://www.macktruckshistoricalmuseum.org/-/media/files/museum/g-model-faq.pdf?rev=9af9c3b4171a46a4944ae8e1caf7e3fa&hash=A661054EBD3DE8B3CBEC5171BC25354B

Might be worth checking with Watts Mack. If they are not available through Mack anymore they might know of an aftermarket source. Honestly your best bet would probably be to just buy an entire rust free cab from a wrecker or junk yard and cut out the panels you need.

https://www.freightwaves.com/news/mack-trucks-fires-back-at-striking-uaws-new-demands/amp interesting article on the subject….

Aren't G models rare or something? And isn't there some controversy as to whether or not they directly copied Kenworth's cab design or something like that? If your looking for one there is one for sale listed on Marketplace in East Greenville, PA. Says they repowered it with an 855 Cummins. No affiliation just passing along the information. https://www.facebook.com/marketplace/item/1137160024337850/?ref=search&referral_code=null&referral_story_type=post

I think Mack engineers knew what they were doing when they designed their engines. There is a reason they have the reputation they do in terms of longevity and fuel economy. If there was a benefit of 500+ HP E7 then one would have been available from the factory. When the E6 and E7s were new a12 liter engine was best suited for the vocational market and linehaul markets where you were hauling legal weights or less, which was Mack's bread and butter. When you send away to the Mack museum for all the literature and documents for a specific truck you will see that each chassis was designed for a specific use case and a maximum speed at a specified grade and GVW as requested by the customer/dealership. From there Mack engineering would select (or recommend) the appropriate engine and gearing to meet those requirements. I think a lot of people asking for more HP out of 300 or 350 Mack engine have other things working against them or are trying to use the truck in a way it wasn't originally specified for. A 6.7 Cummins rated at 350 HP? 😂. The B10 Life for that engine is 250,000 miles. I seriously doubt a 6.7 Cummins under the hood of Mack CH tractor would make one complete trip across the country at 80,000 pounds GVW all else being equal. The power density of the light duty diesels way too high for the type of longevity class 8 engines are expected to get. I think most people (probably everyone) drive entirely too fast. 10-15 over the posted speed limit is basically the new limit. Modern vehicles have got to be so powerful, quite, and smooth that its so easy to unconsciously pick up speed. Modern brakes and suspensions make the extra speed very easy to handle. I think a lot of that carries over to trucking. Guys want to be able to effortlessly fly up big hills and keep up with 4 wheelers.

I'm just now looking at my third picture closely and see that Pete behind my truck had twin stacks. For what? There's only one manifold on his engine. Figure out what that second stack and muffler cost him over his sand career for zero benefit or increase in reliability. Its not a meaningless amount.....

Well lets see it. It started out as day rate. You were paid $2500/day whether you hauled a load or not. This was in the early days when the shale boom was first getting started. The infrastructure was in its infancy and a lot of the pressure pumpers didn't have their $hit together yet. This lasted for about 6-10 months depending on who you were working for and to some extent the well's owner / lease holder. Once it got to true tonnage you were paid down to the hundredth of a ton, so every 20 pounds. So yea....every pound mattered to some. The rate was set depending on the loaded miles from the well to whichever sand yard you were picking up at. Same with the fuel surcharge. Detention was paid at $75/hr after 30 minutes of loaded inactivity. This eventually crept up to 2 hours of loaded inactivity. To some there is. Why leave money on the table if you don't need to? I saw several guys removing their passenger seats, switching to super singles or low pro tires, running 2 batteries instead of 3 or 4 and removing one fuel tank...among many other things depending on the specific truck. They were super committed and willing to go into the weeds and put in the effort for an extra $1500 - $2000 / month. They knew it wouldn't last forever and were only there to extract as much money out of the gig and get out when it wasn't worth it anymore. I don't need a spreadsheet to know if you can cut out even 500 pounds and add that to your net you are going to make more money at zero risk to reliability. At $42/ton, 3 sometimes 4 load per day, 6 days a week it adds up quick. I saw several O/O that got out of heavy haul and into the sand gig. They had heavy tractors to begin with. They went through all the effort to put PTOs and blowers on their trucks but neglected to remove the big chain cabinet from behind their bunk. Like everyone I'm sure they made great money but they also left so much behind. Like I said I never really got into it because I was already pretty light. I worked at night most of the time and hauled overweight. A lot of those sand yards were run by cowboys and would let you leave at whatever weight you wanted to haul. No risk of hitting scales at night. On a few occasions, if the fracking was running super smooth and I was in and out real quick at both ends I would keep 4 or 5 different logbooks with staggered start times and just keep getting while the getting was good. That is all old wives tales and gossip about getting drug around with a dozer in the oilfield. Possibly during the early works of pad construction if your dump trucking in stone. Once a pad is built and and ready for drilling the local roads are modified to take heavy truck traffic and the lease roads are nicer than most local or county owned dirt roads. Zero risk of getting stuck. Like I said before to those guys money is no object. Once a well gets drilled and they start fracking a lease owner can't afford to be messing around with stuck water and sand trucks. At least in Southwestern PA and Eastern Ohio I never saw a lease road that was in any way sketchy or risky to drive on. I don't really know. They must do OK. They are one of the larger dry bulk only carriers in the Midwest and have been in business for over 60 years. They must know a thing or two about specing a truck to maximize ROI for that kind of work. I don't know I lived it for several years and crunched many numbers over that time period. It was always worth it to be as light as possible if you were willing to "do without", go through the trouble to shed unnecessary items or replace items with a lighter equivalent. But you certainly didn't have to in order to make an excellent profit.

I don't know what you mean by this. Its basic math. If you are able to lower your tare weight by X your net will increase by the same X regardless of the pay rate. And yes we were loaded to the last pound plus on every trip. Loaded on a scale under a silo most of the time. Even loading via a conveyor the metering scales on those are pretty accurate. If you told them you wanted 45,000 pounds put on you got extremely close to that. I don't know, the boom cycle of the oilfield is a different animal. The rates were so high money was basically no object. If you wanted to spend stupid money on getting super light you got paid back extremely quickly. I never really engaged in it since I was already pretty light and yes super singles scared me. The guys that did what I described previously about going after every single pound were only there to make money and couldn't care less about looks. I think a lot of them bought trucks specifically for that work and parked their over the road rigs. Sent them to the auction when the bust came. I think the company that had the feather weight Volvos I was talking about did contract pneumatic bulk haul for many different industries/customers. Basically their only business was tonnage so it paid them dividends to be as light as possible since in the non oilfield bulk haul sector the margins are probably razor thin. At the time I kind of admired the way their equipment was spec'd since I knew what I was making and could do the math on how much more they were making with each trip.

The thing about the 12 speeds is they are somewhat scarce and when you do find one they are rather spendy.....at least around here.

Just continue with the plan of running an E6-350 and get a duplex or triplex. Plenty of gears and they should bolt together. Don't lug it and you should be fine. For hobby bobtailing or light loads I would think you would not have any problems. I had a B81 that was repowered with a 237 maxidyne and it still had the 18 speed quad box. It was completely fine for just driving around in......
