Bullheaded

I'll see if I can get a part#, but might not get it until next week. Everyone up here has them on. Helps with the 454/460's too, got rid of that little shake when pulling hard. Then you can put them fancy chrome intake grills on the side and not worry about restriction.

Thanks for the pics and info. It's cool to see trucks like that still working. I have a couple books on the history of Mack and they mention the LR, but there was no pics. So the ones they used in the Arctic....is it possible they had Cummins in them?

John, somebody still has a Mack LR still in service? Are those the same as the ones they used up the Arctic when they built the dew line? The only pics I ever saw of them were the ones in the Bulldog magazine a while back. Do you have any pics of one? I read they were 600 h.p. What did they have ....Detroits?

Thanks for the info David.

Nice. Thanks for the pics. (It's crying for an E-9 though!)

Thanks guys. I was just wondering this because I never saw many DM800's around here, but the RD800 was real popular in Canada. Still a few hauling logs just north of me, with the planetary rears. The DM600,and DMM are everywhere, pretty much own the ready mix market here. The only DM800 I ever saw in person was about 20 years ago. A guy that I recently hauled for with my dump truck had a const. business years ago and he had one that used to be a float tractor with a winch on it. When I saw it 20 years ago it was retired and pretty much nothing left (it was scrapped not long after). All I remember of it was it had huge frame rails, big 58 or 65,000 rears on camelback and a V8 Detroit and two sticks. It had to be late 60's or early 70's I think. I do know the RD800 was introduced in Canada for 1982. I have the 81/82 Bulldog magazines announcing it. They were built in Oakville, Ontario. Say's production scheduled for Feb. 1982. The EM9-400 listed as base engine. Another thing I noticed, in the vol.82, no.1 issue of Bulldog, they show a project in Sri Lanka where they shipped a bunch of steel hood DM686SX's to, and you can see a couple steel hood's with center mounted cabs like the RD800. One has breathers on both sides and Australian style snorkels. So basically I was just wondering if they had similar frames.

After seeing the awesome pics of the big DM800 by 45LMSWM, it has me wondering......the RD800 being the newer of Mack's heavy haulers.....did it have a bigger stronger frame, or is the DM 800 even or better as far as chassis strength?

Thanks John, keep the pics coming as you get her finished up. I think that might be my new favourite truck.

That's a really nice truck John. Do you have any interior pics?

Ya, that's why I thought, the only way to do it without spending a fortune would be to just put a stick controlling an air valve for your splitter like they do with the 18 speeds the show truck crowd is doing.

Maybe they were made by the same company that made the ASSET cams, turbos and electronics.

I hear you Rowdy. If I won the lottery I'd have the nicest Mack dump truck...slash flower pot parked on my front lawn. I'd fill the box with loam, plant it, then sit on my couch and admire it.

Just don't price it! Unless they've come down....I looked into it in 2005 and it was scary. They work awesome off road though. Will put you in where a 6x6 will go. One of the big lumber mills up north of here won't even hire your truck to pull logs from the bush if you don't have it. It really saves the roads.

There's got to be a way to do it. Just look on some of the "largecar" sites. All the show truck guys are doing it with 18 speeds, to make them look like two-sticks.

Gambi80 I had a 2002 9900i, highrise, Cat powered. It was a beautiful truck but you are right about the ride. It had 14000 front/46000 rears same as the 2000 CH before it. But with the CH I could drive down a logging road with an open cup of coffee in the cupholders, when I got the binder, I pulled out of the yard on paved highway and the coffee was blowing out the breather hole in my travel mug lid like a giser! But today at 1.4 million km's that binder/cat is still running up and down the highway with nothing but a water pump. Motor has never been opened up except valve sets.

That lightning bolt (electronic malfunction) light might be a tough one to find. I had a new 2000 CH with the 460 in it and I used to get them all the time. But mine would actually shut off for a split second while driving down the highway (just the same as if you turned the key off and back on). Engine and all electronics would shut down. Brought it to dealer many times, no codes. They went through all the wiring, even changed all the little pins in the ecm plug. Even had the service manager come on a trip with me to catch it in the act. Had his computer plugged in and the darn truck ran perfect that day. Last year I came across the new owner of this truck and asked him how it's been. Said he loves the truck, but asked me "has it ever shut off on you before? It does it all the time." I pulled 5 axle walking floors with that truck, grossing over 140,000 pounds all the time. As far as the truck it was perfect. Ride, handling, off road traction was great. Fuel mileage beat all the Detroits in the fleet I ran for and didn't matter if you did 55 or 85 m.p.h. But it was one of the lucky dogs that came with casting sand in the block. It went through five compressors, five air dryers, camshaft, dropped valves, injectors and the starter caught fire. And it was like a light switch. One hill it wouldn't pull, then the next 12%'er you thought the clutch was slipping because the rpm's would start climbing, then suddenly it would be pulling like a train. That was the the truck that scared me into buying an International.

Thanks MackCL96. If Pitts. new box works as good as their Cat box that would be good news. I also just found another site. www.nwtruck.com They're in Alberta Canada. They show injectors and turbo that claim to dyno 563h.p./2000lb./ft. for Mack E-tech.

What's the details on the Steinberg box? Never heard of them.

Good to hear CXN613. Hopefully we hear more good news. There are two big outfits here in my area that are running Granites with MP8's with DPF's (tri-axle dump trucks) and I never see them stopped on the road doing regens and I never see them at the dealership, so there must be some good ones out there.

I'm just really suprised (especially with the poor performance of a lot of late model Macks)that nobody has broke into their ecm's yet. There's all kinds of aftermarket ecm's and programmers for Cat, Cummins and Detroit, like the Pittsburgh Power box. That's why I went with a Binder and a Cat. Unlimited power and a fuel mileage increase when driven easy on the lower settings. It would be nice to see a tuner for Mack, as the Blixxton's only worked on the older models.

I don't know much about them but a contractor I had my dump truck hired on with leased a couple of them for themselves. I don't think you need anything too special to run them because their tractors only pulled end dumps. And when one was down for service they just stuck any highway tractor with a wetline they could find under them. Maybe some side dumps are different though because I don't believe theirs were powered down. Be carefull if you do pull one though. I have pics of a brand new Paystar like mine laying on it's side with one. We were hauling blasted rock and they put a big nugget in it and over she went when he dumped.

Wow, thanks Daveigou. That's interesting.
