might go with if i got some time. are you getting a hotel, or do youhave friends that way??

congrats Doug. As a kid I thought U's looked ugly. then I drove one and discovered how good they really are for city use.

Hi Mike. the owner told me that the superliner that did the full pull works a few days each week moving machines on his lowboy. His wife was also driving a superliner that looked simmilar to his, I belive he said her truck worked every day as a dump truck. there is a truck pull some time at the end of the month in belvedere if you are intrested.

I will be soon adding a 2 line wet kit to my truck for use in a dump and lowboy setup all the older Macks I have driven with wet kits had the pto mounted to the pass side of the 6spd trans and the pump was mounted to the frame rail powered via a drive shaft. I have some used ptos at the yard that need nothing but some seals/orings and a air actuater on the PTO as it was manual before... any tips from the experts on what I should or shouldent do to make the set up easy and reliable? this is my first time working with a PTO set up so besides working the levers and switchis on the dash this is all new to me Trent

do all the pics from the east coast look like that .LOL welcome to the board. lots of great people and topics here Trent

glad your back Doug. hope all is well. look at it this way...now you can fix all those little things on the truck wile you wait for your full strength to come back Trent

it looks to be in Ok shape but $7500 is too much in my opinion. you could get a better truck with more goods for that amount. I got a good running Mack in Febuary for $3,000 and drove it home from KC to Chicago with no issues. The off set cab had a few diffrent models U, DM,DMM, Im not shure when the U model was retired? I belive the DM,DMM sieres was the only offset models availible untill it was discontinued when the granite was recently introduced. this is all hearsay from the mack parts guy. so hopefully its got some merit B models were replaced by U models in 1965-66 and later that same year R models were introduced. Many dont know but mack made a "kit" called a BCR. it could make the B model in to a R model. the kit included a cab,hood,and other basic parts, you used the B model frame and drive train and bolted the BCR kit to it. they are rare and I have only seen 2 in my time.

if I remember correctly the 600hp cat has the same tq output as the 550 cat. last time I checked I think thats what I read I drive an over the road 1997 internationa eagle at work and it has a 550 cat with an 18 speed. not shure about the rears. I also work part time at a construction company that has a superliner with a 440 E9,and a 18 speed. I have never had "go" between both at the same time, but i can say they do feel simmilar in power. The mack E9 has the traditional low down tq and the cat is happy in the higher rpms. also the E9 does not have any of the problems most people say they do. I do know with a mech E9 you cold get lots more from it than an electronic 600 cat.

Are you driving the RS700 there mike?

yea all the trucks looked good at the end seen. must have been fun driving a truck thru all those buildings LOL

gotcha...the one that runs thru all those buildings chasing the squad car... LOL priceless

I agree larry when you flow more fuel you dont always make more power, other things like timing,injector size,more air are all needed to safely make the HP. but its always fun to do a smoke show Trent

havent seen many RS700Ls "convoy truck" with single axels but i think roadway had lots of R700s with S/A??

Thanks Tim. I did not know such a machine was availible. I was at my local Mack dealer tonight and they do have that machine you speak of. I might have a go at it after my rearend gets rebushed. Update on the shaking problem. Tonight I installed the new rear cab rubbers and it has improved the ride BIG TIME!!! i still get a slight shake but it will go away as soon as I knotice it. The old rubbers were smashed pretty bad and the hole in the steel cab support is oval so it looks like the shaking has rounded the hole and was not helping the problem. one thing I noticed is that when I removed the old rubbers the nut was not very tight. When i put the new rubbers in I tightend it untill I could see it begine to squezz the bottom rubber. the cab now sits maybee 1/4 inch higher and rides much better. i did a few laps around the yard and i could hold 2nd gear to the floor and still see straight LOL. I then did a quick 6 mile trip over a concrete hwy and thats where I noticed it did not shake like it used to in the 30-45mph range. hope this helps Trent

the pump can be messed with to flow more fuel. without looking at the pump its difficult to explain exactly what to do. its not difficult but I had to let an oldtimer show me the ropes and I havent messed with it sence. some things you can quickly check is that the stop cable is not holding closed slightly. and that the fuel lines are not clogged with rust or muck in the tank. I found a clogged fuel line on a 10 wheeler once and it had no power or smoke. On my R model I put an air swith in the dash to controll the puff limiter, when I bypass the limiter and stomp on the pedal (show pourpose only) it smokes pretty good.... like it should. My b model has been parked for 3-4 years but it throws a good cloud when I switched gears. P.S I asked some more people about your truck at the local truck pull last weekend but had no luck getting info...sorry i will keep trying as someone has to remember it

cancel that its Pick up trucks. lucky I called to check on what they ment by "trucks" oh well theres always next year Trent

here is the link http://www.mchenrycountyfair.com/Grandstand.asp Aug 7th at noon and 6 PM Rt 47 and county club road dont miss it and dont be shy. I did my 1st pull last weekend and its not hard on the truck. Trent

Good info Frend. I thought all tip turbines were water after cooled you could use a remote water source and pump to better cool the water . I know some dragracers that do this. the set back is that a seapret radiator,pump, water lines and other misc things need to be added and it will take up some space under the hood. also the OEM aftercooler may need to be modified to not let engine the hotter coolant in.

sorry you dident find the issue Jim. I went to mack today and ordered the cab bushings to see if that helps any?? I will reply back when they are installed. P.S. I had big time "scrambled eggs" doing the semi truck pull last night LOL

the newer mack engines just have a front mount Intercooler the tip turbine macks from the 70s/80s had a aftercooler mounted on the side of the engine and they used coolant to help cool intake temps trent

Truck pull was great. it was my first time and I managed a 220 foot pull or so. It almost was an all mack event except 3 petes and 2 kws and a international snuck in the back door. No boken axels so it was a good night The red E9500 superdog from WI won the event with a full pull!!! I had the lowest HP and least amount of gears to use and was withing 10 feet of the avg pullers. i had to use 2nd gear as 3rd is to tall when the weight comes up on the tandems I might use 3rd next year just to see if the momentum will get me farther?? Trent

You can contact the mack museum and give the serial number of the truck. they will provide you all the info of what the truck had when it left the assembly line. if its only got that many miles it sounds like a good deal. im not shure what trans it has as some times people replaced things over the years. A "standard" R model from that era would likely be equiped with a 237hp-250 hp, non overdrive 2 stick 6 speed or single stick 5 speed, with 34,000 rear ends. all trucks are speced diffrnetly but that combanation seams fairly common. at least here in chicago most R model macks with mack transmissions that had 2 sticks will be a simple 5 speed main and the aux box will have Direct/low and reverse/ giving you 6 speeds foward and 5 in reverse. if it is a 5x4 that would be a quad box and you will have 20 gears. My 78 mack has anti lock brakes but they have been unhooked for what looks like years. On my mack there should be a silver alum box mounted foward of the first rear axel driver side. thats where mine is if you need quicker info and cannot wait a few weeks for the museum to get you the info. get to your local mack dealer and ask them if they have any records of your truck. Good luck Trent

they are regular light bulbs. I also put 2 oarnge bulbs between the air tanks. it looks good at night. the red lights reflect on the rear cab wall and stacks . makes it look a little evil

here are the new lights i added Trent

what engine does it have fred? is it used in HD or off road use Most of the B models I have seen that had Diesel engines came with 10 or more gears I know some fire truck B models had 5 speeds but they were gas jobbers
