oilburner

Hell! them old detriots were so tough i don't thank c4 would do nothing but black up the side of the block, it would probly land back on the ground runing, and yes it would be leaking a little oil out of the inspection plates!!LOL

Oh good looking truck buy the way!!

That's not to bad of a speed drop, you would probley pull it at 60 with 80,000 lbs, you got to rember it is a small engine, not in horsepower but in cubic inces also, most road trucks have 14 and 15 liter engine in them and are geared for the highway. The mack i run is a ch 613 with a e7 454 and a maxi touqe 13 speed trans and 44 camelbacks with 4.17 gears. at 1900 it will do 77 mph with low pro 24.5 rubber. The hills around here are pretty good pulls and with a lowboy behind it grossing around 60 to 65 i can hit the hills at 75 and top them at 65, buy fliping the trans down in the underdrive postion, so i thank your truck is doing pretty good, they newer trucks just don't proform like the old mack engines did, mash on them and the smoke would roll and then things really started to happen! LOL. I have about had it with the electronic bull#?*!

There was a rs 700 just like that one in a junk yard close to me, it ran and had a blue dot ac on the roof, the frame was shot, but it ran not a mack powered truck it had a shinny 290 and a nine speed eaton in it, had a good hood and the cab was not to bad, would have been a good parts truck, they also have one of the cabover macks i can't rember the model but it is the ones you allways see made into garbage trucks, but it is a mid 70's model with 44 rears, i can't understand why someone would sell thoses old trucks for scrap, they have also got 2 b models, one was a wrecker and they cut it behind the cab and the other is a single axle dump that looks like it is in good shape, man i wish i would have had some cash and got to them before they hit the scales with them!

And i am pretty sure the maxi touqe 13 speed has two overdrive gears to, but not a double over, the 13 speeds when fliped actaully have 3 over drive ratio, to make it a double over because when you split 10th to go to 11th you were in direct in 10th then you split it with the back box and 11th 12th and 13th are overdrive ratios, i thank anway correct me some one if i am wrong.

Yeap that sounds about right, our international 9370 has 3.55 with low pro 24.5 and a 9 speed direct and it does about 82 mph at 2400, but that is a old big cam 4 400,

Well like the other guy said find out your ratio, if it is slow it is not a 3.54, that thing would fly with that high of a gear, a double overdrive is a good tranny if you have alot of engine or just don't haul much. When you make a trans double over you losse you low ratio, because you flip the gears on the countershafts and it makes each gear higher. If it were me i love the 15 speed overdrive with a mack engine, you have a deep reduction in the trans giving you 5 low gears, but not as low as frist in a six speed mack, and tight ratio going up in the gears, but that's just me, some people like super 10's which to me are useless, but they do have the biggest overdrive you can get in a single over trans in a eaton that is. I would not recomend a double overdrive unless you ratio is in the 500 range or so, you would probley never get it in the big hole loaded.

Just to let every one know we were messing with the truck today and found there is a problem in the wireing harness in the cab at the fuse and relay panel. we were trying to get it to start and i was standing buy the pump with my hand on it listing for the fuel to turn on in the pump, my buddy while in the cab was checking the fuse panel and then he pushed on it and i herd the fuel cut off click, i said it will start now what did you do, he replyed nothing i just pushed on the fues panel, he rech over and hit the key and it started right up. Has anyone eles had this problem before, and is it common on these trucks, it's a 98 ch 613 with a e 7 454 in it.

Ok guys, this truck is about to make me pull my hair out and go back to drivin the old international!! You all may rember it was having a issue when it was cold with smoke and running rough for a few secounds, now it will not start. Well it did after we sprayed a half of can of starting fluid in it, and crank it for hell and ever. The other day it was takeing fits and would quit, but pull over and it would start right back up, go a little farther and it would do it again, now once you get it started it is fine untill you shut it off, then the same problem. No engine lights are on and malfution light, could it be the econovance finaly kick the bucket. Hey any info would be greatly apprecaited!!

Not bad for the money, around here we would put a 200 dollar paint job and some tires on it and go to work, i wonder if the hand saw in the floor board goes with it for that price! LOL

Keep up the good work!!

I hit the like button to, keep up the good work, and share a picture or to along the way!

Yeap i had this happen once, but not with a mack, it was a mack truck but a cat engine, but we used engine oil in the power steering and it had a small leak, it took us a while to figure out were the oil was coming from, the driver said the engine was pushing oil out the dipstick and our frist thougth was it needs overhauled, but when he pulled in we herd the pump wineing it was almost dry, i had a freind that told me to check the pump and he was right fixed the problem. Our 98 mack has looks like hydrolic oil in the power steering i don't know put it looks thin and has a greenish tint to it.

Thanks i did not know that it had two overdrive position, in 12th and 13th, i thougth it was direct in 12th, oh well i am used to a eaton!

The 6.0 is a good engine, but the 6.4 is another story, if you get a good one you are ok, we had six fleet trucks with the 6.4 and 3 of them had engine put in under warrenty, one of them had one put in at 20,000 miles and then had another one at 60,000. and turbos and other things with the other ones. The 6.0 have had egr problems and injectors but at around 110,000 miles. Now the trucks get the piss drove out of them but they never miss oil change, and change fuel filters every month. My opionion is go with a 7.3 if i could they have a 99 with one in it and it has 200,000 somthing on it and it is a 450 with a dump bed and the only thing been done to it is a clucth.

What about the 2130 maxitouqe!!

I know guys that hauled 45 ton on a dm 800, i would say this truck never moved with less then 75 ton on her! Nice video, frist one i ever seen

Does your truck have a air dryer on it, this can also cause problems with the regulator. It has a line that usally comes from the regulator to the dryer vavle and when presure gets to 120 it opens the vavle for a quick secound to purge water out of the system.

Well i thank i found the problem, The truck has 24.5 285/75 low pro tires on the drives the other day i had it parked at the shope empty on the concrete and i walked to the shead and looked aT the rear drives from a disstance and i could see under the front outher rear tire, i walked over to it and checked the air, it was fine. Then i looked at the inside tire, found the size on it and it is a 11R 24.5 tall rubber. I keep finding stuff like this on this truck who ever had it before was a real lug nut, or maybe the dealer we got it from done it but they claim they just got it in. I am pretty sure this is what has been causeing the hop going to change out tires and wheel from another truck and get rid of the steel wheels and see if this helps.

Hey get us some pictures when you can, happy truckin!!

never been in the seat of 34 with solid rubberblock before, didn't know they made them, but i may be thanking of the old style, you may have something diffrent, i was thanking of the old hendrickson soild walking beems withe the big wide rubber blocks between the frame and the walking beam same as the spring hendrickson just without the springs. i worked for a guy that had that set up but i thank his were 46000 lbs rears, it wasn't to bad with a load on it but empty it was teriable, beat you todeath. but i thank i would pick it over airride, still not that old yet..lol

but then again 84000 miles at 3390 hours is a average of 24.86 miles a hour!!!

The wheel could be broke from no power stearing, 84000 miles comon it had more than that on it by the time i was born... or thats when the cable broke

I don't know about a camel back out doing a walkingbeam, unless they are woreout, But airride any spring ride stands up better and if you have a 16 feet or better long bed it is just pins and nails spreading rock on roads, and i have herd of people turning them over with the beds up spreading before and i can see how it could happen, airride on a dump makes the truck twice as limber when you get the load in the air, and if you are just dumping i like to raise the bed a little and rock it a bit before i open the tailgate get the load shifted back a little so it don't have so much in the uper part of the bed when you get it up. But everyone does what works best for them so he will probely find his own way to get out of the pucker factor. I have never delt with mack airide, never even seen it i guess but if the bags are tall they seem to do better than like the pete bags that are only half full of air because when you dump the truck gets ligther and the bags can not dump the air quick enough and the truck starts raising up and that can cause it to lean to the heavyer side and you can feel it in the cab, if the bags are already tall with air it is not so bad because they are as tall as they can get anyway, but if it has a dump vavle it is a whole lot better good luck, i wish i had some cash i would take the old 74 off your hands you don't see many of them around here, it would proberly be a long trip to kentucky driving it!!

Hey maybe keep the old truck because if you don't like the airride you could upgrade and put the old camel back under it, but yea you will get used to it but you want forget the frist pucker you get from it. Good luck and by the way what rearends are in the ch?
