Got any more pics of your Great looking Superliner? I think thats the first pic I have seen of it. what are its specs?looks well taken care of..

if I understand this question he is saying the inlet lets in alot of dirt and collects in the bottom of the can, There are a few products that help sift the dust out before it enters the filter housing. Its called a pre cleaner. It lets in air but makes it travel in a rotated path, as the air moves around it forces dirt to drop out and fall into a collector that can be emptied out when you see it full. Lots of construction machines have them. also stop following that guy that is driving in front of you. I often see guys following each other to close and the guy behind the lead truck is sucking in all that kicked up dust and dirt!.. stay back in the clean air!! pre cleaner image http://www.google.co...=1t:429,r:9,s:0

First thing I look for when I have bad MPG is what is my Boost vs EGT readings. Its a good indacation how your air fuel ratio is doing and if your down on power. Restricted fuel flow does not really hurt MPG. Restricted air will reduce power. If you have low boost you have a leak or clogged fuel filters. low EGT tells me it is not getting the fuel it needs. besides that winter blend fuel will reduce your MPG.

Great looking Superliner. Just a little TLC and it will stand out for sure! what is the wheel base? Looks like its around 230"? My RS had a 36" sleeper when new. it has a 206" WB ...kinda short for my liking if it still had a sleeper..

Did they ever decide to build the Big HP Maxidyne? think it was a 550 or 605 HP? saw it displayed at the Con expo show years ago...Would love to see how that would run or even better put with a newly designed 12 speed! Trent

Welcome to the site. Cant help with the newer mack stuff... try posting this question in the Modern truck section or in the genral discussion section..more people will see it Trent

Try Grandrock.

thats good to hear I last ran in in April and they gave me a whole 3/4 of a right lane to try and snake up the hill. was kinda scary with the heavy traffic, concrete walls and a1 million dollar trailer behind me.

yep...a lot of in and out...Seen r model fuel tanks with worn down steps.

nice truck there Love the long hoods! Greco Const out of mt Prospect IL (Chicagoland) had 2 just like that used for their low boy trucks. V8mack 6 speeds 4.17 rears,Budd front spoked rears small fuel tanks. they were red with blue stripes.Both had rod and main troubles but were fixed. they also had bad cab mounts at the rear as the bad roads. the interior floor beam was bent upwards! just beat the hell out of them. they were up for sale for 10K each about 5 years ago. heard they went to Africa?

looking good. all you need is some nice stainless fenders and dont forget about some old school Mack mudflaps

if you can get that load of wood with it... you could sell the wood off and it would likely pay for the whole truck!!!! not a bad deal if your local..

that was why mack built the rear mount PTO... so that you could spread and did not have to take the aux out of gear .you just turned the pto On then raised the box. the only thing I did like better with the side mount was that it did raise the box faster if you had light loads such as snow or broken concrete. just grab 4th and she went up fast. But as you said the rear mount gave you better overall options. just my .02

Bullhead.....Now thats a heavy haul Titan , it looks like a HD truck and has a sleeper for todays standards. WHY CANT MACK SEE WHAT PEOPLE WANT IN A TRUCK THESE DAYS??? there is nothing bad with a small sleeper but just look around. how many small bunks do you see. not many... that mack cab already has all the rear wall provisions for sleepers yet mack ignores what all the other heavy haul truck Mfg seam to be selling. when was the last time you saw a convoy of 100' windmills pulled by day cabs with a 36" bunk??? thats right never!.... And do we think a driver wants to sit in his seat when he has to take a piss while he is waiting for the wind storm to pass? where does he go to relax when he is stuck on the on ramp for 5hrs?

congrats on the new truck... The CH is a workhorse those on off valves are rare on the new trucks but you will love them when its time to replace a heater hose, air compressor, or have to make a repair to the water system. keeps the water in the engine and you can just drain off the part of the system your working on. When i bought my RS700L It was middle of Febuary and the heater motor was not working.I had to drive from KC to Chicago. I made it to The Iowa 80 and then just could not stand the cold anmore. I pulled in to the truck stop to buy some allagator clips so I could hot wire the blower motor. Man I wished I would have done that 4 hrs before LOL!!!! I could feel my toes again

whats the trip for? new sled puller?

I know of 2 mid 70s RL700L that had the big bad V8 with 6 speeds, sister trucks. both needed rods and mains every 150K. it was a known issue with them. think they were sold at the 300K mark and were on there 2nd set of crank bearings. Just my opinion here but....the stock engine is fine for what it is but if you want more power and still be safe source a E9 and you will be better off.... you will likelybe able to rebuild the E9 cheeper and have more power than the older V8. If price is the issue dont over look the E7 mechinicals. you will louse the V8 bragging rights but its a strong puller and has the torque you need.

never worked around the Medium duty macks. I thought they all had Renault engines in them???? just rebadged as a mack?

There was a program that really made the electronics rub good but the epa put the axe to it. Last I heard was it was almost impossible to get..

funny how one group says they rose while the other said they declined... you keep all your HOS rules for the .20Cent per mile" professional drivers" and I will just drive my truck they way real truck drivers do. End of story

FAIL!

This should be in the VIP section... That way a much better visual can be had....

Donner pass I-80 CA.... looks like the paved it with cobble stones with some 6" trenches to hold the snow.

I rebuild shocks for race cars. and here is what I can add.. The biggest issue with suspension found on old trucks is 3 things. 1) axel weight. (unsprung weight) 2) they have huge tires that have lots of side wall flex. this is a big issue when the side wall flex fights the spring and damper. you will get a shake or excess movement of the suspension. 3)that they used huge springs that take alot to flex (bump)and thus when they try to return (rebound) to their resting position they do so in a violent movement. When the spring is seeing any movment it causes the shock to resist that movement. the faster the movement the harder the shock attempts to resists that motion.now add in the tire flex and the axel has lots of vibrations(simple explanation!). The shock trys to control movement in both directions and is sometimes valved to resist diffrently in one direction vs the other. For most automotive applacations the bump valving is softer than the rebound valving. even tho a shock is constantly absorbing vibrations it is doing it diffrently depending on its direction of movement. An out of balance tire or wheel can be fixed easy with weights. a weak or soft spring on the other hand will often flex more than is needed in a constant fight to find its level resting point. If the shock cant control the spring then you get vibrations and un needed movement. the old leafs did very little to reduce movement. you had 12 springs that all want to do there own thing. even 3 leafs fight each other. if you notice most truck MFG that set up an axel now use 3 or less springs or just a spring to support an air bag. less things moving the simpler to control vibrations. If vibration is the concern try adding a stiffer shock. if ride quality is also the problem swap in a 2 or 3 leaf front spring it will improve ride and should have less vibrations. Trent

Why not source a more modern intake heater. Will work better and less troubles.. just a thought..
