Nice truck. It deserves to be more than a wall. http://cgi.ebay.com/ebaymotors/1968-Mack-Western-RS-700L-ST-8088-/170480078251?cmd=ViewItem&pt=Commercial_Trucks&hash=item27b1678dab

Yea sounds like it could be the old 8.2 non turbo 4 cycle v8. They were pretty popular in the early-late 80's in medium duty trucks (along with the CAT 3208).

As if the other party wont either. Its a natural balance in our government.

MORE MORE, I MUST HAVE MORE! Love the M series! Thanks for posting.

Mack's were built before Volvo was even a company and built anything.

Another 13 tons wont hurt your 350 at all. Remember that those engines get along just fine here in the states pulling 36 tonnes all the time. Some applications have them pulling even more. And in the US/Canada we don't normally run dog trailer setups like you boys do, but we have similar setups such as transfer trailers and pup trailers.

Hi there. You have a good idea there. But instead of beating your head against the wall looking for a factory single axle sleeper, why not find the truck you want and have it converted to a single axle? Trucks are easy to convert into what ever you want to them to be.

It is. The terrorists are just pussies that hide in the shadows throwing the equivalent of small rocks at us. If the 9/11 masterminds came from a clear and well defined country, it would no longer be there. The problem is they hide among and are hidden by multiple countries that are all shady to begin with and have unstable governments that are based on a religion with questionable teachings. Its sorta like asking the cops to find the punk who threw a rock through your window, it just ain't gonna happen. Our military is very strong because of a big budget and lots of great engineering. No one government or country is going to mess with us.

Its probably Rob, you couldn't tell the two apart.

Amazing post, makes you both sad and mad at the same time. Thanks for taking the time to post. The Mack brand should either be laid to rest or put back on top. There should be no compromises. The V8 was headed to the chopping block in the early 90's. I found and posed a link to an archived article that explained Mack's emission woes in the early 90's and they were close to not complying. The V8 never passed 500HP in the US even though it was probably the most powerful on-highway engine in the word during the mid 80's. Meanwhile it was cranked up to 560HP in Europe and 610HP in Australia matching CAT and Cummins 2050 ft/lb 600HP monsters. The Mack V8's were known to be weak on the bottom end when turned up past 550 or so HP. A Little engineering (you need the right people) and I bet you could fix the bottom end problem, design a new fuel system with EGR, DPF and SCR and be able to blow the competition away. Its not easy but with the right minds who are dedicated you can make things work, almost like magic. There is no limit to HP and torque, even with 2010 emissions. We just have to improve the emissions and/or design new emission technologies. Remember SCR and DPF arent the only two things being developed for diesel emissions, they just happen to be the ones that work at the moment. Oh and one mor ething: Scania just introduced a 730 HP 16.4 liter V8. Peak torque is 2580 ftlbs! But one interesting thing of note is they do not offer a manual gear box with the 730.

That valve is called the tractor protection valve. It cuts the service line (blue) in case of a trailer break away so you can still safely stop the tractor. The valve should be able to be replaced with a Bendix TP-3DC. The three lines toward the bottom are as follows: Two come from the foot pedal primary and secondary circuits. The Third line is the air supply line that is fed from the red trailer supply knob in the cab.

MAybe the best way would be to post the pictures here on BMT so evryone can see them. I know I would like to!

Where did you get that photo? I have been looking for more detailed pictures of M series, planidrive axles and suspension.

Worth it. You are pretty much allowed to walk along the assembly line un-guided. Look all you want and stay as long as you want. So its no so much a tour as it is more like being turned loose in the plant . I went for the first time last year and plan to each time I go to Macungie.

Hey Rob, Looks like you found a new project for your 12V71

DOH! I should have realized that An E9 would have never been in the bay of an early/mid 70's truck. Interesting re-power though.

I believe the Yellow DM800 at the top was built for Australia, I think a mine ordered it. There were also three or four other twin steer DM models made that had 23k fronts and 80k rears. Hauled dump trailers at a mine in Australia. The Twin steer trucks still exist but will be/have been cannibalized for their heavy rears to build new trucks.

Was just browsing some pictures on Hanks and ran across this nice twin steer Hayes logging trick. I have seen a few pictures of it before but never one of the engine bay. That sure looks like an E9 to me. I do know that Mack purchased Hayes and then sold it to PACCAR. But I don't know the years and would Hayes have used Mack engines? OR did the owner fit the truck with the E9? One thing is for sure I really like the old Canadian Iron.

That is true respect. No other brand will ever have the respect Mack has. Many companies and even major projects were built with Mack trucks, its a shame they are all switching to Pete's, Kenworth's and Western Stars. If only the suits over at Volvo would wake up from their money induced haze and realize the true potential of the brand.

Somewhere out there, and MBA is masturbating while reading those buzz words. That is pretty much the root of the problem, the suits are in control. Worst part is the suits are located in Sweden and completely isolated from the brand.

Bad flasher. Its a little round metal can looking thing that is usually near the fuse center and/or relays. It has just two pins and uses a heater and bi metallic strip to open and close a switch which flashes the lights.

Here we go, a Mack magnum

Just found this newly posted video of HHA's day cab Superliner, with a turned up E9, hauling a mobile crane. HHA (Heavy Haulage Australia) has some of the cleanest and well kept heavy hauling equipment I have ever seen. Just look at that dashboard! The poster, texast525, is the owner as well. Turn those speakers up!

58-65 rears will carry the weight but how much off road work will you be doing? I am guessing you might be located in a country that has many dirt roads, in that case the big 65,000 pound rears will get you through most anything. But a tractor with 65's are tough to find. A tractor with 46 rears and a pusher could also handle the weight. But a tandem axle tractor with 46,000 rears that has no pusher will not last long in off road situations. Depends on how fast you need to travel! A lower power engine with around 300 HP will have a tough time with the heavy load unless the differential ratio is very high, say 5.02 - 5.88:1. Your top speeed will be slow but you will move. If you need more speed go with 400+HP and at least a 4.17 rear end ratio. Under 4.17 is mainly for highway use and big horsepower engines (550+ HP).

If you are hauling 40 tons (metric tons?) you have to make sure the trailer is designed to carry 40 tons otherwise you are going to break springs or worse yet, crack its frame. The tractor only needs to be able to carry half the weight of load and trailer. Lets say you need to carry 25 tons on the tractor, 65,000 pound rear axles will work great. Dry gravel is about 1.5kg m^3 so that works out to about 26 cubic meters or 36 cubic yards. Make sure the trailer is a frame type trailer and has three or more axles. You should be fine with that setup. Any truck with 65 rears will be setup to pull that load with no problems. if you go lower than 65,000 then you are definitely looking to add a pusher axle and make sure the differential ratios are high enough. Go no lower than 46,000 pound rears on camel back or some other spring suspension and make sure you have a 20,000 pound pusher to help with the weight. A double frame is highly recommended for your application, single frames will likely crack from the stress. The trailer should be setup with spring suspension, and its axles should be able to carry at least 25,000 pounds (11.34kg) each. 40 tons is allot of weight, you need to make sure the trailer suspension and axles can carry the weight. Many U.S. dump trailers will not be good for 40 tons of gravel. But do your research as some states have overweight laws that let you carry 54 metric tons combined weight on 6 or 7 axles. Those trailers will carry 40 tons.
