I searched google for your question and here are a few links I found . not shure if it helps but some questions were answered. http://aths.org/forum2/thread.asp?m=1405 http://www.ytmag.com/mm/messages/15944.html Trent

Posted on the ATHS also..I removed a bolt off the outside of the rear cab wall on my R model. Im talking about the 2 bolts next to the rear window that some people mount an air line holder when they are bob tailing around. The bolt came out easy then the nut (welded to a stiffner plate or something) droped between the interior and exterior skins. No access hole to get between the panels!! Are ther any type of HD hardware simmilar to a drywall bolt that will securely hold a 4" Service lite to the rear cab wall. If not it looks like I will have to drill a 3/4" hole in the interior wall to get a 1/2 socket back there. Someone suggested a rivnut but im not fimmilar with them . only rivnuts I have seen were small, used for the marker light bolts Trent

there was a Magnim on ebay a few months ago. I belive it was last working for north star transportation or something along that name. I had a sticker on the sleeper doors with the company logo?? anyways if its the same truck I spoke with the owner in NM 3 years ago. It was in good shape for the age and the interior was very clean. if this is the truck Dan Could you Email me any ifo to track it down Thanks Trent

Welcome to the club Van, Lots of great people here (and a few screw balls) to help out with all your questions. Looks like you got a nice B model to restore there. First tip I can give you is to send a small 10-20 dollar donation along with your trucks vin number to the mack Museum and in return you will get all the factory build sheet records for your rig and possibly a 2" thick shop manual for dissasembly/troubleshooting of your trucks componets.

my friend has a newer (2001?) Fullsize Ford Pick up 4x4 with I belive he said is made by anothe MFG? possible IH diesel badged as a ford?? He has it set up to run on grease or diesel. It has some go fast mods for it as well. I was impressed when I drove with him from AZ to Chicago. It can take most stock cars off the line and up to highway speeds. not bad for a heavy pickup. It has a programable chip with 3-4 settings dependingon what he is doing with it. still gets stock MPG or better depending on how he is driving or what program he is useing. some of the older ford diesels pick ups I have driven seam to be a little sluggish. Most were service trucks so the extra weight of the body may jave caused that.

I have heard from the oldtimers that the R700s and RS700s were macks "top dogs" of the R model family back in the day. Then the superliners took over. I dont know about you but the Superdogs and RS macks were always my top pic with the "new" macks. I still think they have nice body lines that many new trucks dont have because of aero concerns

Also for larger radiators with the larger engines

check ebay i see a set of them on there every few weeks. I belive the "new style" are plastic and the old ones will have glass lenzes and metal housings Trent

lucky that train was not going fast. I wonder sometimes what people are thinking when driving!!!!!!!!!! I look both ways when walking across a hallway at work LOL how do people forget todo it over a RR track??? I beleve The last big boy moved under her own power wsa back in the late 50s early 60s soon after there reteriment. I think there is a UP challenger that is in operation for yerly shows?

the centennial was an empressive diesel engine but not practical. I am guessing thats why it and the Big Boys were retired and we never saw another example like them again. I heard the Centennials had drive shaft problems between both engines? It is sad that the 800 sieres is gone along with the whole R family. Last summer I passed up a heavy haul company on eastbound I-80 just past salt lake city. On the low boy was 3 axel RD or DM800 with huge tires and a fancy paint job. I chatted with the driver for a few miles as we pulled over the hill and he said it was going to move a genarator. and some mineing stuff. he was a driver for both the pete lowboy rig and mack 800. he said if the mack could go faster than 40 MPH he would pull the pete on the lowboy and drive the MACK

Moving one of North Americas largest steam Locomotive to a new site. its a Union Pacific 4-8-8-4 Big Boy . Engine weight is 762,000lb tender is 428,000lb Trent

I have seen a few of those KW with the engine under the single seat cab. the cab was off centered werid looking truck??

Gret vid larry . I cant wait to get mine out on the road again. its been to long!! I remember I could drive it like a 5 speed when bob tailing around. but its been 3 years sence I got to use both sticks!!!!

My companys 440 V8 never gets hot but we dont have the hills to pull by me. It has a pyro gauge and it holds around 1100 if we do find a hill to climb. I find with most diesel engines I have driven if it starts to gets hot I can down shift to get the rpms up t 2100 or so and it will allow the fan to keep the engine cool. Only on long pulls out west have I ever had to pull over and let it cool for a few. One thing I never liked about the 6 speed trans behind maxidynes. was that the engine lugs when pulling the BIG hills and will start to get hot quickly, then the fan has a hard time trying to supply the needed air flow thry the rad to keep cool. Trent

I liked the older ones for there apperace but thats about it. I drove a Rental century class last year and it rode very nice but had no balls at all. dont like the styling at all now. In my opinion it is just a cheep truck that has no real appeal to owner operaters.

Look like some hevey speced axels on those granites. That old butterfly hood R has a good size load of sand!! would never get away with that here in IL.!! Merry Christmas and Please get home safe!! Thanks for doing a great job over there.

Hi Joe I did a truck pull last summer at the local Lake county fairgrounds with my RS700L. It was tons of fun (pun intended) A friend of mine on this board (bulldogbred) lives near me and he turned me on to the truck pulling. He has a RS700L with a 300+ with a 12 speed. he can pull better than me with my little 6 speed. A bunch of the local Dump trucks show up to compete. Northern IL Mack is also there with a few of there dogs. I have never been to any other pull events but would love to get some info about your truck. Maybee this winter I can take the my dog out for a stroll down by you and see this monster rig you have. let me know Trent

Hello Joe I Live in Fox lake, work M-F in Lincolnshire, and on weekends I drive a dump truck allover chicago land aera. I see a few black cruise liners hauling tankers near my house but there from WI lots of superliners still left to bee seen in Chicago !!!!

some times it almost seams more reasonable to spend the $5000 on a whole truck than just the motor. I have seen some "junk" trucks with V8s in them for pretty cheep. they likely are pretty ruff on the outside but atleast you get all the other parts needed with a E9. I am waiting for my bosses superliner with a 440 HP E9 to die, he does not think he will rebuild it because of the cost and age of the truck. I talked with him about buying the truck when he wants to retire it so that I can save it. Trent

I have a 1978 285 HP tip turbine. with a 2 stick 6 speed. engine code ETAY676 Maxidyne 283HP@2100RPM 1080 ftlb @1020RPM the ETAY673 and ETAZ673 I belive were econodynes and rated to 315HP 1080ftlbs. They were recomended to use with gearboxes with 9 + speeds I think the 237 was a ENDT675 with 900 ftlbs. look on the pass side of the engine for a tag with engine code info

thanks for the info. I thought there was a conversion kit but just my luck that its no longer made. If thats the case, how are the rebuild kits for these air motors? I have never rebuilt one and would hate to go thru the trouble rebuilding one to find it works just the same. I have driven some R models that the air wipers work great and then some R's (like mine) that turn on and stick on the first cycle. Trent

Any one ever switched the air motor out for electric. I think the air is cool but it does not work as nicely as the electric. I was thinking about geting 2 electric motors, one for the B the other for the R. How easy is the swap? is it a direct replacement using the same mounting holes? Besides the elictrical hook up what diffrence will there be? Trent

Great looking 700 you have. looks like you cleand her up under the hood also. whats the next plan(s) for it. Trent
