Yes I did know the motor was considered an E6. Thank you for the info on all the other rated HP motors. I am slowly learning more about Mack trucks then intended haha!

It looks like that truck has 56K rears. No leaf springs

I wish I woulda found that truck first ha! If that has a 300 motor, is it a ENDT or a E6. Don't ENDT's only go up to 285hp from factory? I would want to change the tranny on that truck and get rid of the front pizza cutter steers, those tires will sink on most of my jobsites!

Ya that's what I don't want. I was thinking with the 285hp motor, turn it up to 300/ 350, with a 18 speed tranny, 24.5" tires with 4.17 rears I could hit the bottom of the hill with enough speed and momentum and split gears on the way up keeping the rpms higher and not loose to much speed before getting to the top.

I could settle for a 12 speed would love to put a 18 speed in it someday (if it can handle the motor or the 285hp motor down the road)

Is there an 18 speed that can handle this kind of motor? the motor I would love to have in it is a 2 valve 285hp with a large fuel pump to get it up to 300hp - 350 hp. I think I want to stay with the E6 motor just for the old school feel/ sound.... DO YOU THINK ITS WORTH KEEPING IT THEN AND RUNNING IT FOR NOW AND SLOWY FIX IT UP AND REPLACE THINGS AS NEEDED OR DO YOU THINK I SHOULD SEND IT DOWN THE ROAD AND WAIT FOR A DM 886 WITH A 285 MOTOR? WHICH WILL BE MORE IN THE $20k - $25k. yes they are insanely reliable and can take a lot of abuse! which is why I'm a little nervous to send the RD down the road and have this DM take its place, I don't want the DM to be a problem child. Keeping both isn't an option because one will be sitting way to much and become a mouse heaven! and my problem begins!

are the 285's just as reliable the ENDT 676? I'm ok with not quick, I just don't want to be going 10 mph up a hill haha. I totally agree with the no payments!! No payments is way cooler to me then a $100K financed truck!

Ok, I did notice right off the crack the engine idles much lower then our E7 RD

I told that to Joe, that I probably wouldn't of purchased the truck if I knew it was a 235hp and he never responded back.

yes it will be worked hard. off-road and over loaded often! See the picture of our RD, that is what this DM will be doing!

I am starting to see just how pieced together this truck is! It is leaving a very sour taste in my mouth! I do not like the thought of a twin stick they get annoying to run after awhile haha. probably because they are before my time, and I am not good at shifting them !!

How does my 86 DM have a 1974 motor in it ha? I was thinking the 1974 was the emission compliance like it says in the picture below. But then it does say date of mfg. does MFG mean manufactured ?

Trans is a fuller 13 (least what I was told) it looks like I could see eaton cast into the top of the trans. the info plate has been removed from the trans so not sure what type of 13 it is. Probably not the right one judging by all the other miss leading info I have been given on this truck. If I did find a pre 1988 DM the way I wanted which I haven't been able to yet. It would be a $30K - $40K truck probably (350hp motor, 13 or 18 speed, converted hubs to hub piloted, 4.17 rears for better highway speed, pintle hitch with air ran to it, with demo box and multi function gate, and painted black ( we paint all our equipment black ). If I slowly build this one into what I want I will probably still have $20K- $30K into it, but the paint will be fresh the motor and trans will be new. I wouldn't be replacing a lot of this stuff until it goes bad either. But maybe you are right also, that's what I kinda trying to figure out I guess. How quick will the motor shred the trans? 200K miles 50K miles? It will be worked. Overloaded with dirt spilling over the side off road (sometimes in soft soil) is 100% in its future that's why I got a Mack and that's why I wanted a DM. That is what our RD has been doing for years now.

That's what I was thinking when I offered $10K, that I would have some $$$ left over to fix and switch some of these things! and by no means do I plan on doing all these things to this truck over night, I would probably run the motor and trans until they need rebuilds then swap them to what I want instead of rebuilding. It does suck the motor is only 235hp and not 285hp I'm just not sure how it will handle pulling the 20 ton hoe from jobsite to jobsite. First thing will be the rims converted to hub piloted with 24.5 tires if I decide to keep the truck. Then I will probably put 4.17 rears in (just for better highway speed). I am also trying to figure out if the rears in my 94 rd could be switched to the DM. The RD has 4.17's or 4.11 (which I know the 4.11 are not true Mack then, we switched out the rears in our RD 2 years ago and now it does 75mph wrapped out!.

I tried to locate these numbers on the trans, it seems the info plate is missing or is there another place?? Im assuming by how everything else is going with this truck its probably the 12!!
