Al Did you show these pics to Bob Hall(think thats his name?) from Northern IL Mack Grayslake? He had some good stories about This truck running out to the east coast and back. I was in there a few months ago and he was telling me how he would spray the whole frame and aluminum parts down with diesel fuel when he was heading into a snow (salt) storm. Im assuming this was after the first cab was junk in short time and his 2nd cab was installed?

I have a 1982 Hilbilt "Contractors Special" Frameless that im getting ready for sale. This has the side rails that are a few inches lower than standard. it needs welding to the underside, new tires and a U bolt. it has new electrical to the rear, all new brakes and hardware, retractable pull tarp, New Hyd Hose, Fresh exterior paint and new bearings. I bought it in 2007? used it for a few years weekends only and now it has been sitting unused for about 5 years. It needs some TLC but it is what it is... send me you email if interested.

I always laugh when people would say that cats and cummins have a flat torque curve just like a Mack. They think low rpm is 1300rpm Never have found a diesel besides a Maxidyne that could pull good with a 5 speed

let me guess $500+? thats what it was last i checked?

I have thought about getting mine painted like this one. I would need to buy a winning lotto ticket,get fiberglass hood work done first. Then find a heated garage to keep it in!

Just think if this Clown had known about this message Fourm before he had hacked it apart. He could have sold it for 2x as much and still had his dignity. Shake my head

Dont shoot the Messenger... Al Can fill you in on these sad details..........

Love the look of mufflers on superliners...... Until I'm trying to back into a dark tight spot in traffic....then you can't see crap in the mirror or if you have your head out the window....LOL

Use a plumb bob( spelling?) Hang it from the top of the door jam and see how far off it is at the bottom. I suspect the cab may be tweaked. Seen a lot of bent cabs from rollovers when the mirror brackets hit the dirt hard.

I have driven trucks with the same issue. And like you no matter what new parts you throw at it you just can't seam to make it stop. It sounds like you replaced just about everything so you may need to keep adjusting things untill it tightens up. Did you put the bolts in the hinge that you can only see when the door is fully open? I recall there being 3 bolts total where each hinge bolts to the door frame.?

Would love to hear how they developed it. I really think the maxidyne is one of the best diesels ever produced.

Al Does he still paint? Was maybe thinking some day i should get a flashy paint job like that?

What a great looking truck! Thanks for taking the time to post more photos of this truck. I really like the larger sleeper he installed.

Personally for a dump truck keep springs for the tractor and air ride for the trailer. You get better traction for the tractor and the trailer with air wont bounce and buck you around. The ride quaility with a air ride trailer is night and day. Always dump the air bags when dumping.

May he RIP......Was he the inventor for the maxidyne principle?

If what you are saying is at 1900 rpm you see 63 mph with 4.42 rears and tires with 513 revs per mile my math says you have around a .78 overdrive. If you went from a 4.42 down to a 4.17..... Your road speed would be 67mph at 1900 rpm This is assuming you have around a .78 overdrive

I have a 711 non turbo with a straight pipe. IT IS LOUD inside the cab. I think its louder in the cab than from standing next to the truck out side.

i bought some green plastic toggles and I had to put a dab of rubber calk in them to get them to have a "tight" fit. Other wise they would slide right off and flop around on the toggle.

wasn't it a brand new truck? 120K sounds about right for a new truck

I tend to judge things by its cover........you think that guy has ever set foot in a truck?....be honest now!

Looking good. You need a gold dog for the hood with all the " go fast " work you have done to it!

I was at there south Chicago yard a few months ago and they had lots of cool pictures in the office. I dident know they had superliners and valuliners. They use to be all Mack but I saw alot more Freightliners there.

I had the pleasure of working for a company where fuel milage was nothing more than a game of who could put the most amount of $$ into the tanks. The "best" I ever did was just over $1400. That was with a truck that could carry 300 usable gallons on the tractor and 35 for the trailer. This was back in 2007? when fuel was at $5 a gallon. We fuled up in northern Cal or Southern Oragon. The 5 of us pulled up and dropped about 7 grand at a little ma and pop gas station. the owner was smiling and We all got a free soda and sandwich for the road... LOL That being said we were sponcered by Texaco, and they paid the fuel bills no questions asked. Those trucks had 550 cats and good tires. They had a lifetime avg of 5.0 MPG (good times)

Check basics first. Are the tires the same hight? Are you on perfectly level ground? Check by placing a level on the pavement. Then across the tandems. Also chech ride hight loaded and unloaded. To see if your withing spec one way and not the other.

Mack made a rear mount pto that will fit the 2 stick 6 speed and 12 speed transmissions. as long as the 12 speed has the splined countershaft it should install just like they did with 6 speed. Look at the rear countershaft covers for a stamp to indicate it is splined. It should be stamped with a "s" or an "x" I can't recall If you want a married pto/pump unit the 6 and 12 speed has provisions for 6 and 8 bolt ptos I don't recall a rear mount married pto as an option from Mack or other vendors? In my opinion the Mack pto was the better of the 2 options.
