oilburner

Oil Burner if you get down into mid TN and want to go for a ride in an E9 truck hit me up Im all for showing the ways of E9 power, and the one I have now is stock(for now). I have pulled Jellico with several trucks and its a good test for sure, Black Mt in NC is a good pull and short as it is Mt Eagle on 24 in TN is another one that will make the real trucks stand out in a field of amateurs, its a short pull but its 7.5% and curvy to add to it. I dont think those out west truckers have any idea what a real hill is they have long pulls but they are straight as an arrow compared to east coast hills and not as steep, at least all of em I have been on(several). I hear ya on the 1693 clatter, they sound like theyre coming apart till they warm up dont they, the 3408 is a good engine when its right but they have issues like all the big engines do and they are getting even more rare than the E9 so there is little to go by for comparison, I kow where there are 3 and 2 KT600 Cummins engines, which from what I have been told by the old timers are the baddest thing on wheels till a head gasket goes and they always go, any engine with 6 individual heads and I think 6 bolts per head not run at constant speed in equipment as it was designed will have issues. I would love to have a KT truck and a 3408 in the driveway with the E9 all I would need then is an 8V92TA and I would have em all.

I hear you for sure, I Know were a kta is that was having issues that was pulled out of a superliner but i would say it is in need of alot now some parts gone and set outside in the weather for years. If i ever get out your way i will let you know and would love to go for a cruise in that big dawg, i was out that way a few months ago we went to baskin truck sale and got the ch there, on the other side of nasville, i don't know how close we were but we were way out 40, and thanks for the invite, if you ever get close to jellico tn or williamsburg let me know, i may not be able to take you for a ride in a impressive truck but i can show some, and around, and if it is at home and not on a job we can ride the ch around and maybe check out my buddys superliner if it ever gets out of the engine shop!

To all the comments on E models, I think the E model is a great engine, but I dont think it was the best ever, I still think that was the B model. I may rate these things differently than most though, since I am a mechanic /driver, I rate them by reliability and the E model had more issues than the B hands down, the B's just ran forever if you took care of em, the E models have what people here call the E model shake when they get some bad fuel or water thru the fuel system it gets a miss thats hard to find using injector cut out tests. I know I have been around about 20 or so that had it I know of 6 right now, I know that you can throw new injectors, new fuel system check valves in it and it will fix it but it just seems like it should be easier to diagnose and fix to me. The first C-15 was actually just a 3406E with a new name it wasnt a 15.2 liter like the ACERT engines they came a year or two later, the first C-15 wasnt bad, the ACERT sequential turbo engines had some pretty serious issues with heads and turbos for the first 3 years and they have gotten the reliability better now but its still tainted to me. As far as stopped making it, well they didnt they just stopped painting it yellow its blue and gray now and its called the Maxxforce 15 the Cat C-13 is the Maxxforce 13, Cat and International made an agreement that Cat would supply engines to International if they would build them a truck thats why the doors on the CAT truck look like International doors, they are.

84 superdog, i thank along the same lines i would rather have the b model as the e for one major reason, no check engine light to come own, but i have never seen any major problems with one, we had a 3406E 435 hp that had 1.2 million miles on it that was purchased from a lumber mill that got it new, and said it had never been into, but it was a 1800 rpm motor and it had been well taken care of never missed a oil change, we used it 2 years and all we did was replkace the ecm, and had to rebuild the jake. Now i drove a c-15 that was a 550 and that truck would tear the road up but it was pleged with problems, broke rocker arms, bad oilcooler, injectors, and a cracked head thing never ran hot but somehow the head was cracked. The e model was a 95 and the c15 was a 2000 both were in freigthliner fld's. My dad had a cabover pete with a 1693 425 in it when i was about 5 and i can rember that thing starting in the morning what a racket it made when it was cold, but everone around braged on it how fast it would pull jellico mt. loaded. Now the e9 mack have got to pull good they are a big engine, and a v motor on top of that it has to make awsome touqe, Like the 3408 cats but i have yet to take one for a spin but maybe someday i will get a chance but i will proberly have to buy one frist.

Well i was afarid it my be bad news, it is like a high pitch wine, Now most eaton fullers 13 and 18 speed make a similer noise in the rear box mostly the 1400 series but only in the overdrive postion at mid range in the rpms, but this one does it in the underdrive postion at any speed and it gets louder with engine speed, shift it in direct and it is quit as a mouse, i thank i will change the fluid in it this weekend and service the truck it needs a good greasing anyway. I am starting to like the transmission i hop it is not nothing major, does anyone know what oil to put back in it, or what it calls for, it is a 98 model T2130.

That is why i love this page, it is full of mack pro's and people that have experience with the old macks, and every post i read i learn something! thanks guys i hope i can help out some of you guys sometimes.

The early 350s were series tip turbine intercooled, dont remember what year they came out.

That is what i was thanking, but did not know they made a 350!

How much trouble is it to add power steering to a '69 R 600 w/ 237 Maxidyne. I have "armstrong" power steering now that is long on arm and short on strong! Do I need to find a donor R model for the equipment, or will any power steering system work?

i would say a donor truck would be best thing, i did see one once that had a add on air operated power steering, but the owner had it changed to a regular power steering he said it did not work good.

a 237 is the ENDT675 Maxidyne engine,and while they will work with a Duplex,Triplex,or Quad,they were designed to be used with the 5 and 6 speed Maxitorque transmissions.One of if not the best engine Mack ever designed.

A 250 is the ENDT673C Thermodyne engine,rated at 250 hp,with a operating range of 1500 to 2100 RPM,these were better suited to the B model transmissions.

Most of the time,what's referred to as a "300" is actually the ENDT676 Maxidyne rated at 283 hp.These had a tip turbine fan and intercooler set up,andlike the 237 were designed to be used with the 5 and 6 speed transmissions.These engines were available starting in 1973.

An actual 300 hp engine was introduced in 1980-81 as the E6-300,this was considered an Econodyne engine,with the front mounted air to air aftercooler.

So there never was a tipturbine 300 built? And what was the deal with the tiptubine was it just a water to air cooler with a coolant fan in it or was there somthing eles to it. and i was thinking a e-6 was a 4 vavle engine.

Has no one ever ran one of the 13 speed macks before, i was just wordering if it was a sign of trouble to come or if they are like the eaton 13 and 18 speeds, they have a slight wine in the overdrive position.

Yes the b mpdel and e model share the block but the head and fuel system is the big change on the two, the crank journals are diffrent also as so of the c models as well, i like them both but if i had a otr truck the e model would be my frist pick, now if i were local hauling coal logs or somthing like that give me a old B model,

Its a little harder to screw with the E models, so they are more dependable than the b especially if you have a driver in it, the pistons can handle the heat better and you can't mess with the pump on the E models, i have know guys to back the screws out of the pumps of the b models trying to get more power till they fall out.

What did they do for 24k put a new crate motor in and give you enough parts to rebuild it. That is why I do all my motor work. I dont like anyone else in my motor. Oiloburner an E model is just a B model with an over head cam and steal pistons. The E still has the B model cam jernals in it. The Acert cat motors are junk stay away from them.

I dont see a reason to rebuild until there is excessive blow by, or engine noise, of course a c-15 sounds like its falling apart off the showroom floor. I dont think I would ever buy one I know everybody I know that has em has had issues with them, the early c-15's at Howard Baer all had broken head bolts and bad actuators, a couple of them were down so much they got rid of em. I hope you didnt get an Acert c-15 they are worse about actuator issues, turbo issues, and get horrible fuel mileage for the power they make, I think Cat quit making engines after the 3406B and just cobbled the rest together from parts they had laying around. if you want a new Cat C-15 go get a new International with a Maxxforce 15 thats just a gray and blue Cat C-15.

i do like the old b models and i like the older a model and the 1693, but the 3406E is probely the best cat made, a 475 or 550 E model is very depedable, the c-15 did have head trouble and the twin turbos gave even more trouble, that was for that bad word emissions sake and why cat stoped building the big engine.

I'm buying a truck has a c-15 cat engine 475hp with 1 million kms, i'm planning to put a gravel box on it, my question is how long this truck will run before i have to re-build it? or since the construction season is almost over should i re-build it in the winter and get it ready for another million kms? i live on the other side of montana border in canada and the mechanics here a so greedy and i was told on the USA side it is way cheaper to re-build the engine. tell me what you guys think and what do you suggest?

thank

it is about 12k here if the head is good and you don't need injectors or anything like that, now that engine is what we call a million mile engine around here, i know a guy that has a 550 with 1.2 and he rolled in a set of bearings, but if the truck runs good and don't heat up and has normal blowby run her, if it ain't broke don't fix it i guess would be rule to go by. And if you do go threw it go back with cat parts not aftermarket you will save money in the long run.

oilburner where are the egines locate.

williamsburg kentucky!

I really think your family should find a way to keep it or loan it to a museum For free but you keep the title and in charge of it. You may be surprised that down the road your son or another relatives kid may some day enjoy how well maintained your grand parents kept it.

I hear to many stories of people trying to find a old car or truck that shared history with a deceased or older generation family member.

I can tell by a few of the pics that he did a lot of upgrades and kept it very well maintained.

Just my .02

Trent

could not of said it better, i think it would be worth more to you and your family then what it would actally bring in todays market, i would keep it myself if were you and there was anyway at all i could. But that is just me i am a truck nut anyway and have always liked the old mack trucks, just thank about it, maybe even talk it over with your family if it is something you would be willing to do, its not like the truck would sell for 80,000 bucks but if you keep it long enough you may have that much fun with it.

I don't know what the truck would bring just like it is, but if you could but batteries in it get her running, and pull her out do a good cleaning, and odd and ends that usally happen to a truck while sitting, this will maximize the price, now if you done that you may decide to keep it yourself she is a beauty, now i have seen old restoraition b models day cabs around here that look fair and run good and drive for 5500 to 10000, nicer the more money, but that sleeper cab has got to be worth more they are rare.

Oh yea and if you have any documention paper work stateing were it was bought new and how many miles and what has been done to it this will help you to. History helps sell old trucks

I thank they will interchange, I know a guy that has one of each, complete engine and transmission, he wants 1500 a piece for them, one is a 237 with a 6 speed and the other is a 250 with a 5 and a 4, the both came out of dm 800 coal trucks the 250 is a 72 model and the 237 is a 75, but that would be a long ways for you to come get them. And they both have jacobson jake breaks on them.

I never drove a 12 speed put i did drive a 10 speed that had 2 sticks, it would have been alright if it was airshift, i didn't drive it longe enough to get to like it. I still like the old 300, i drove a 2 vavle 350 with a air to air that done good to but to tell the truth i could tell the differnce in the two put it did have a 15 speed fuller and between gears the ratio were very close it didn,t heat up as bad on the hills. I thank the 15 speed is a good set up with the old mack engine, but they did not have the low hole like the old 6 speed put they were better out on the highway.

that old 350 had the best engine break i ever seen on a mack to, it was a dynatard, we had to work on it onced because one head quit and i thought it was the craziest looking thing, it had a pluger in the rocker arm and the oil presure pushed it out and caused the push rod to keep presure on the vavles, but the owner told me they were harder on cam shafts than a jake, he had already put one in it, but it held back pretty good.

Thats how my 300+ pulls. I can run with the guys with 425hp up till 45mph. I think if it had a 12 speed I would have no problem running with them. I have a spare 300+.... I wonder if it would fit in the CH?

If i recall right the 300 was a maxidyne and had more tq than the 350 but a 350 had more hp and if geared right would out pull a 300. My thoughts are a 300 is a better off road low rpm lugging engine and a 350 was better narrow power band engine suited to on road duty.

The 300 i drove pulled real good, it was a 80 model and had a air shift 6 speed, and it pulled good everwhere in the rpm, but when you pulled it down to about 1400 it was like that was as low as it would pull down, it would go there and hold 1400 very good, and for a truck that just had a 6 speed in it would do about 72 2100 and i ran it there alot, the truck was proberly the best pulling truck i have drove but i do rember the pryrometer was somthing you had to keep a eye on it would heat up on a long pull and you could downshift it and get the rpms up aroud 1900 and it would cool back off again, if it wasn't for that i thank it would pull hills in high gear loaded, you guys may thank i am blowin smoke, and that old 300 blowed alot of it, but to me mack quit makeing good engine when the 4 valves came out. I have drove alot of the mack E6 and E7 and eveytime it just dissapoints me when i thank about that old 300. I have drove 350, 400, 427, and 454 and none of them would pull with it, and the guy i drove it for still uses it and as far as i know all he has done to it was have the jake heads rebuilt and a new turbo, i guess emission are what holds the newer engine back but to me nothing like the old non-electric engines The 300 i drove was a tipturbine, you could rush it though the gears empty but if you done it loaded, it would heat up and smoke bad, the owner said the fuel was turned up on it but i thank it might of had a little more timing than factory, it was a triaxle log truck and we usaly gross 70,000.

What do you all thank about these trans, The one i run wines pretty lound in the underdrive postition is this a sign of trouble or just the way they are.

One othe thing, is it me or does it have three dogs on the hood!! i bet that thing will run for sure, that cat sure does have it work cut out for it with 3 dogs to keep up with!!lol

Cat in a mack is not a bad thing, usally they will leave any other truck in the drit even if it has the same engine for some reason they run better in a mack, it must be trying to keep the dog in front of it, cat's and dogs don't mix, and me personaly i don't like the mack trannys, but i leaned on a eaton fuller and they shift a little diffrent i guess it just what you like or are used to either way i drove one just like it but it had camelback rears and a 13 double over trans and it would pass every truck i ever cam across loaded, but i will say that it is in the shop now because the driver after me did not pay much attention to the pryrometter, and it galded a few pistons if it would have had a 350 mack in it it may still be going, but any way nice truck i would say it pulls good, good luck.

The 79 has a puff limiter and it works. Im shifting between 1550 and 1650. It has no power when crusing down the highway. I'll drop from ninth gear to seventh on the same hills I don't have to shift with the 79 6 speed. I've had three mack dealers tell me the internals are the same as a 300 to 350 em6. But they all tell me I have to do diferent things to acomplish that. One tells me injectors, the next tells me injector pump and turbo, and the last tells me all three. The rpms are ok. 1650 to 1700 at 70mph. I just want to maintain that speed when loaded like the 79 can.

I am sure that the timing is one of the biggies, and the injectors, but the rest i'm not sure about, but i will say this the old 300 tiptrubine engine will do there thing about anywhere in the rpm range, from 1000 to 2100 they pull great, and i would rather drive one of the 300 or 350 than any of the late model stuff as long as they are hot and have a good working pryometer in it don't want to turn it in to toast, best old engine mack ever made in my opinion.

I drove a 365 hp detriot once that was a low rpm engine, being used to a 2250 rpm i could not belive how weak the thing was. I was coplaining to a guy about how it had no power and he said i did not know how to drive it! well i was a little upset by his worlds so i said well hot shot driver how about a lesson, and he gave me one he said to never shift it over 1500 and and down shift it about 1250 or a little before it may seem like it ain't going to do it but it will. Now i thought about it and what he said so i tryed it and to my suprise that was the only way to get up to speed with it, i was always hitting the gov. before shifting and it was just a dog. The engine pulled better at 1500 then at 1800 why they would make a engine like thiss i don't know but after looking a a hp and touqe chart for the engine i could see that is were the touqe toped out, it made some more hp but the touqe would fall off after that. Now that was not a mack and may not help at all but it did make driving that old truck a little better hope this helps you out.
