You can't flow time that pump?

aint no big mike obama either!!!!

That's a 2 valve. Million mile engine...

I think the E6 was a two valve. I thought they would be more compatible, but they were not that E6 was a running son of a bitch. Well, I finished the velvet adjustment. I was gonna set the timing, but I figured that’s enough for the day. It’s a lousy day with no sun.

The E6 2 valve is commonly regarded as a harder and tougher motor than the 4 valve As they say "she'll pull christ from the cross" or "she'll pull the ass outta the ocean" 2 valves were the very best motors of their era Paul

I gotcha now!

Yes but you need to move the engine 30+ degrees back then go forward to remove gear lash.. a little gear lash effects a long way... Got it ??? The engine runs clockwise...

they must have put the duct tape on it early since they know it's going to fall apart shortly after running down the road. no tape on the true MACK LTLSW

You have to remove the front cover and the 4 bolts on the pump gear. Leave the gear meshed in the hole. The pump coupler will come out with the pump. When the pump is ready to install. You will use the light timer to make sure the pump is set before installation. then install the pump with 2 bolts secured in the pump gear. Then back it off 30+ degrees, and bring it up til the lights match, and check the degree mark on the flywheel. 1/2 degree early is ok. If it is on the mark, lock it down.. your done... There are a few others here who know this better than me. I expect one to chime in.. jojo

Mech, glad you are here. Take a look at the other thread im posting in. Its about pulling a RB inj. Pump. I posted some info, but you may/will be able to fine tune the info..

So you have n E-7. With a Robert Bosch pump. Yes you roll the engine until both lights are lit. If you pass by it, back off 30+ degrees and try again. Then take note of the degree mark on the flywheel. You can also mark the plate on the pump gear just for extra reference. Then remove the pump. Will you be able to leave the crank shaft position alone during the pump work?

maybe to blind man.

i will also add, if they ever offered an LTL glider kit, i would snatch one up.... then stuff a 600 HP X15 cummins with allison trans in it just to use as a daily driver.

I think the E-6 4 Valve came out in 1987. And then in 89-90 the E-7 was born...

i bet they would sell like cold beers on a hot summer day.

That was interesting note Bob about that big difference in properties of 300 4V compared to 350 4V. I belive 300 4V was EM6 so Maxidyne and E6-350 is Econodyne. But physically they're both almost the same engines. The difference must be in the fuel pump settings and the turbo (if I'm not wrong). So the fact you shared surprizes me a bit. I have both types of engines in my trucks right at the moment. But didn't experienced 300 4V on a highway since it's not road ready.

ok 2 more cylinders adjusted,,,,2 more to go breaking for lunch

The Antique Truck Club of America National Meet is in Macungie on Father’s Day Weekend. It is an all make show but Mack’s do represent. Mack Days is in Lititz PA the first Saturday in October. It is also an all makes show and is out on by the Central Pennsylvania Chapter of the ATCA. Both are great shows.

haha thanks for that,,,,didnt do anything today but yes that steering box is next and one axle seal,for now,,,i might have to swap trans soon since i have it kinda sitting in the way where it is,,,,and thanks for the happy cheers vlad,and yes steel dash,,,ive been a big fan since riding with my pop in a 1970 U model at 14 ,,bob

Damn, I was going to ask how could you get the engine into the cab?? Ok, I also have a DM but probably have never taken the dog house away. Nice thing about your truck is it's steel dash. At least it's on my taste and I just forgot the fact. And I don't feel guilty now for not paying attention to the thread for a while, read all the pages I missed in the last couple of months. So wishes of good luck on the progress whatever it will be the hood, tranny, steering gear... And sure pictures

Well, I take that back. I did buy a used 87U model and Fontana California back in 1989. They had a bunch of them that came from Golden State foods it was only two years old.

Every time I read that title B 67 don’t know where to start all I could think about is this thing?………POS DM600 don’t know where to start. but then I’ve been in this area for 45 years and it’s the only one of its kind that I’ve ever seen for sale.

haha me and the mrs had quite our share of bourbon last night

Clearly that's the motivation you need Bob Time for the cook to inspire you ha ha ha ha Paul

my god,,,,what a doll thanks paul,,,,got alot done yesterday,,,got everything apart and was able to set 4 cylinders,,,number 6 and 2 so far were way off,,,,i was impressed with myself i pretty much stayed out there for most of the day,,,,was almost 80 here,,,,bob

We actually still have a couple Superliner coins left and maybe some 125th Anniversary coins also! Coin #4 is also in the works an will be a B-Model Design!! That's all I can tell ya for now! Stay tuned!!

Don't worry about stuff falling in the motor, thats what the oil filter is for 😁😁 You Im pulling.yah leg and been silly The older we get the harder it is to get motivated, especially when hot, doesn't get cold here But just turn the T.V. off and start seems to work, I think working for myself most of my life I have had to go out and do as no one else is here to do it Because I care I have a helper for you A different Mrs Mack than normal ha ha ha Paul

don’t know about you fellas, but it seems like everything I do around here whether it be the Mack or home repairs everything takes way longer than I figured still clearing away a bunch of clutter dirt dust of the valve covers before I try to remove them or even take out the bolts I don’t want any shit falling in.

No thanks for that. I think I heard somebody mention that in a previous post I will definitely check that. I can’t figure out why there wouldn’t be a pointer on it. Not sure if I motor manual mentions that or not but I didn’t completely comb thru it I do recall it mentioning the flywheel I’ll crawl under there in the morning and take a look

Boy..does that sound familiar. Plus i'm into my fourth year of "covid long haul". Some people say"no such thing- I say bullshit. It just effects people in different ways. As for me, lack of strength, tiredness, brain fog.."where is that XX?"..right where I just looked five minutes ago! Last year I started bitching to my PC doc about how this was dragging on. He looks at me and says..."But you are 80 years old"! I said yeah and two years ago I was 78 and I was doing stuff a lot of 58 year olds could not do. Case in point I was having troubling starting my Stihl 036 saw. finally I'm searching on line and find some gal who works on saws..subject was hard starting..and she says..." now you guys who have these big Stihl and Husky saws, it takes a lot of snap to start these""🤔I ended swapping it to my son for his smaller saw.

Bob. I am somewhat in the same position.. After retirement my motivation level went way down.. After them morning news I like to check my emails and truck sites, THEN I have to force my self to get off the computer and do something.

It would be a Robert Bosch pump of that era. The easiest way to tell is where you screw your injector line on. The Robert Bosch pump has a extremely fine spline barrel nut that takes a special socket to remove the barrel and replace pump washers. The American Bosch pump was way more low profile where the injector lines screwed on. The fine tuning of the pumps were not done at the dealerships. This was a pump shop type of repair/adjustment. However like some people said I remember removing the top cover marking the position of the sliding rail with a punch and moving it forward and test driving. I’ll see if I have any information on it in my old manuals at work

I just priced new door shells from my local Mack dealer. They were about $1,300.00 each.
