Bullheaded

Ya. They will build you a 6900XD off road with planetary rears and an Galaxy stand up sleeper if you want it. Want twin steer on that too? Sure. Want 600 h.p. and 2050 torque? No problem. Hell, up until just last year they would still give you a tier 3 Series 60 engine for off road use.

You got that right!! Nice white chassis for a life in the Alberta mud! LOL

So to add to the What is This Thread where I added the other pics, here are a couple more. The introduction of the Canadian developed and built RD800. The awesome CL350ST. The description is #2. A very cool Superliner add. And a Superliner Boom truck I have drooled over ever since I first saw it.

I really want that yellow DM dump!

My night shift snow haul got cancelled because they need the equipment to plow. So I dug up two of my old Canadian Bulldog mags. Sorry though....I took the easy way out and just took pics. But if you save them they can blow up to be easily read. And no I DON"T CARE if anyone uses my pics, LOL Got a couple other cool ones to show you but I'll start a separate thread. The DM's here were not out of the ordinary.....but it was those steel hood R's that caught my eye when I first saw this, because this was just before the RD800 was released.

I gets depressing looking at the antique and classic Mack section of the forum and seeing all the dominant heavy haulers Mack once had. Like the DM800's to the CL350ST to the M Series off road trucks. Sure you can say those markets have shrank to the point of being unprofitable. But Western Star and KW seem to be doing OK with it. Especially now that Mack HANDED over all their customers to them. Just look at the Western Star 6900XD line and all their partnerships with body companies to equip them. https://www.westernstartrucks.com/Trucks/6900/ Tell any of the loggers here to buy a Mack and they will laugh you out of the forest. All the heavy float and logging operations around here that had CL700's and Titan's all have Stars now. The Titan could have made it.......IF they gave customers what they wanted at a price that was comparable to Star and KW.

I'll see if I can dig them up and scan or something.

I have two Bulldog magazines from 1982 I think (because they covered the introduction of the Canadian built RD800 and also featured the CL350ST's) and they have a lot of these steel hood R's in these issues. There was a bunch shipped to Sri Lanka for some big project.

Friend of mine had a winch tractor that looked just like that truck, except it was a DM800. But it was also yellow. Had an 8V71 Detroit in it and a two stick trans (can't remember what version) and it had the Mack 65,000 rears on Camelback.

I remember living this nightmare. My 2000 E7 460 came back on wrecker the first 5 trips I made with it, with a cooked compressor and the air lines melted off it from the sand plugging it up. Finally got that cleared up, then it dropped a valve, LOL.

So far so good. Still loving this one. On my third week of snow hauling in the city, and still not one parked regen called for. My 2013 DD15 would have had to do one every night. And this truck will easily outpull it. So don't know if this is a result of going to the smaller displacement, or if it is improvements that have been made to the emission system over the last couple years? But the DD15 was more forgiving if you let the RPM's drop on the hills. This DD13 is stronger as long as you stay on the boost. If you let it fall off the turbo it won't pick up like the DD15 did with it's two stage turbo. I wonder if the new DD15's still have that same bottom end power now that they went to the normal VGT turbo? That 2013 505/1650 DD15 would actually out accelerate our ISX 600 that had with the exact same gearing from a stop light with 140,000 pounds on. But of coarse on a hill at highway speed once you started downshifting, then the ISX would wave ba-by and disappear.

I was gunna say call Cummins. They will sell you engines heavy haulers want, LOL. (well some anyway...I'm a Detroit guy, LOL)

Well I'm getting soft in my old age because it's the working and trying to keep the truck working in minus 40 that I am starting to hate, LOL.

I'm on night shift snow haul in the city. This is week three from when we started. I had posted pics of our snow dumps last winter. Last night I was talking to someone from the city works department and they said we hauled over 7 million cubic metres of snow last winter. That was just us hired trucks.....did not include the cities own trucks.

You bet! He kept it right to the end too and wouldn't let anyone have it.....so it ended up rotting right into the ground. My father always bought new Mustangs too. But up here with the salt....everyone used to drive their stuff year round not thinking those old cars were going to be worth something, so they all rotted away.

Hahahaha....that brought back memories. I had an uncle (now deceased) that used to put chains on a 69 Boss 302 and drive it in the winter, LOL.

I know my friend did it on an RB model and I don't think he had to do much. But there will be others here that will know better.

I have a friend that has a new Granite dump truck with the M-drive auto trans. He was telling me that any time the speed sensor malfunctions it derates to low gear and you cannot upshift it manually. he said he has tried manual mode, performance mode, etc. You are stuck in low gear until you get it to dealer. Is this true? Or maybe something that has not been programmed in or something? That alone would turn me off from ever buying one. I once delivered a truck for my dealer that had an Eaton AMT. The ABS light came on and it would no longer shift in auto...but it least it would in manual. But I hate those Eaton AMT's. They shift so rough. I'll stick to my trusty 18 speed or an Allison from what I have seen.

The mass ground point inside dash on driver side A pillar. Clean and check your grounds. At least that's what it was on my 2000 CH when I used to have it. Always had the malfunction light coming on and off and the truck randomly shutting off and starting right back up while driving down the highway. Dealer never could figure it out. They changed all kinds of harnesses and ecm. Was just the mass ground. Found out many years later.

Smarter than Volvo marketing, LOL. They should hire Iam's dog food to market the Mack brand, LOL.

See the cylinder with the 2 air lines with the Drive Products decal on the bottom of the PTO. That is the air shift plunger. The back side is where that little keyway slide is and you can see if it is travelling. Get someone to go in the cab and get someone to shift it up and down and see how that is moving. In the old days it was open on the back so you could hit it with a hammer but now they all have that cover on them. You can also take the air lines off (and check for air supply) and remove those 2 bolts and slide cover off. There is a piston with o-rings inside. Make sure it is clean and lube it with some Krown or Fluid Film orsomething similar. That is assuming you can remove it. Sometimes the pumps are rotated to a different orientation on the transmission. I had one Freightliner Classic that I had to drop the PTO from the trans and drop the oil to get that plunger off. Not a fun job in the bush when you are working. Hopefully this helps. I suck at trying to explain stuff.

I just saw a commercial for Iam's dog food on TV and it had a bulldog pulling a green Mack CH. LOL Somebody in their marketing department was smart enough to see the connection.

I'm still going to say check the air plunger for travel first. I've had to replace new ones because they were scorded inside. But yes, if new, will be warranty. I'll get pics later. Going out in a bit to get truck ready for tonight. Minus 25*C here, so gunna go clean the snow off the truck while the sun is out, LOL.

These are the guys that pretty much "owned" the ice roads of northern Canada. They built and maintained them and controlled most of the trucking. The real ice road truckers, not the fake TV bullshit, LOL. https://www.cbc.ca/news/canada/north/tlicho-investment-corp-creditor-protection-1.5383266 This link shows all the companies they own: https://www.cbc.ca/news/canada/north/tlicho-investment-corporation-cleans-house-axing-17-of-its-companies-1.3710018

Give us more details and I can give a better description of what to do. I can take pics tomorrow of mine to show you where to look.
