Popular Post fiveseven0trkr Posted April 27, 2023 Popular Post Share Posted April 27, 2023 (edited) Hey y'all, just bought my first Mack, a 1971 R700. It's set up as a water truck, has a big cam in it and a Eaton trans. Bought it out of Oregon and have one of my drivers in the area this weekend so hopefully I will get it home (central PA) to give a good going over in a week or so. Didn't really need another project but it isn't often to see a long hood R for sale and for <$5k I couldn't help myself. My dream is to install a 5th wheel and sleeper and put it to (occasional) work pulling step deck / low boy like my other 3 trucks.

Hans Remmers Posted April 27, 2023 Share Posted April 27, 2023 Looks pretty much original and unmolested with the pre plus 3 cab still intact. Just wonder if someone did in fact put a big cam in it as they weren't yet produced in '71.

mowerman Posted April 27, 2023 Share Posted April 27, 2023 Wonder why the nose seems extremely long???? Quote Link to comment https://www.bigmacktrucks.com/topic/72781-r700-venture/#findComment-530070 Share on other sites More sharing options...
fiveseven0trkr Posted April 27, 2023 Author Share Posted April 27, 2023 Thanks mowerman. didn't see it in person yet just going by description and pictures. I might be mistaken about the big cam, will find out soon 🧐 Also I'm gonna display my ignorance but what is the plus 3 cab?

mechohaulic Posted April 27, 2023 Share Posted April 27, 2023 now this is a post that will attract a lot of attention. many here will be looking for picture up dates I'm sure. all the ideas follow through that will make one fine looking tractor.

Hans Remmers Posted April 27, 2023 Share Posted April 27, 2023 In 73 they started coming out with a cab that was 3" longer behind the doors. Around here the old cabs all rotted away years ago. The short grab handles are a dead giveaway. That truck should have a steel dash and the parking brake valves mounted on the back wall between the seats. They're really neat and you seldom see them anymore. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72781-r700-venture/#findComment-530076 Share on other sites More sharing options...
mechohaulic Posted April 27, 2023 Share Posted April 27, 2023 based on alum battery covers/ step ,other give aways; looks to be steel frame rails, possibly that's a RS 700 western??

mowerman Posted April 27, 2023 Share Posted April 27, 2023 Yes, I thought it was a plus 3 . It’s something to do with the photograph. you look close and no it is not. Yes as he said it was 73 they added three extra inches because tall guys would not fit in them before that.Bob Quote Link to comment https://www.bigmacktrucks.com/topic/72781-r700-venture/#findComment-530082 Share on other sites More sharing options...
doubleclutchinweasel Posted April 28, 2023 Share Posted April 28, 2023 I drove an early R700 a little bit. Had the V-8 Maxidyne with the 6-speed Extended Range Maxitorque transmission. It was the early cab, like that one. About a '70-71...had the darker green interior. That thing was a beast. But, the Maxitorque took some getting used to, since I was used to the 18-speed. I kept wanting to shift too quickly! The view over that longer nose was really something. Felt like there was a mobile home sticking out the front of the cab! That one does LOOK like a western model. Maybe can find out more as you go. Looks like a great find. Love the flat-back, all-steel, green-on-the-inside cabs. Look forward to seeing more on this one. 1 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

fiveseven0trkr Posted April 28, 2023 Author Share Posted April 28, 2023 (edited) Thanks for all the info guys. I did confirm that my driver is going to load it this weekend so I hope I will have it in my crosshairs mid to late next week. Cannot wait to crawl over it and get some solid info. The cab interior is all steel and luxurious pale green😍 I will post pictures when I get it here and can take some in person. I never thought much of it when guys will buy a truck at an auction, sight unseen just going by pictures but I just now joined that crowd. However, if I would have flown out and looked at it first I woulda spent more on tickets than I paid for the truck so who is losing here 🐶 doubleclutchinweasel I was wondering if there was any R700's that came with a V8, thanks for that info. I was previously under the impression that superliners were the only trucks with that option. Also I am not convinced this unit has a big cam... It is a Cummins but the guys that were selling are just the auction company and I'm not convinced they know enough about older motors to properly identify it 🤷♀️ Edited April 28, 2023 by fiveseven0trkr 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72781-r700-venture/#findComment-530217 Share on other sites More sharing options...

Oh boy now you're making me nervous lolol, I will definitely be taking lots of pictures but this isn't going to be a six digit, every nut-and-bolt, frame off restoration. Cause there isn't six digits available to make it happen. lol. I'm hoping to have a lot of fun with it and end up with a somewhat user friendly sleeper truck. But I currently have my Marmon tore down for a motor rebuild and just got the motor back. After that's stuck together and making revenue again, this ol Mack is next! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72781-r700-venture/#findComment-530218 Share on other sites More sharing options...

There's build numbers published on this but I think a lot of R700s were built with Mack or Detroit V8s. Lots of "vendor engines" put into the 700 series R models. I think the holy grail would be to find one with a 1693 Cat or the big, purple Allis Chalmers engine if such animals were ever built.... 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72781-r700-venture/#findComment-530219 Share on other sites More sharing options...

Pretty sure it was. Also, I think the grille was different...had the "horse collar" around it...like "The Duck". Some of the more experienced guys here will have way more details on the western stuff than I do. 1 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

See the brochure below. Think this was about 1972. There are Mack (864) and Cummins (903) V-8s listed there. 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

That's the first thing that triggered "west coast" in my mind when I saw the original picture. 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Vladislav Posted April 28, 2023 Share Posted April 28, 2023 Judging by the pic it's RS700 definitely made in Hayward not Eastern R700. Has straight frame rails front to end, fuel tanks with "stepped" shape of the bottoms and front end appearance as the Duck truck had. Actually it would look almost like Duck if put a sleeper and paint black. Interesting example definitely. Good luck on the project and we all waiting to see more pics.

fiveseven0trkr Posted April 29, 2023 Author Share Posted April 29, 2023 Thanks mechohaulic we really like that trailer 53' with 2 lift axles so it's easy to make it Cali legal. truck fired up and drove on the trailer under its own power! yes height was measured, it was 14' from the earth to the tip of the exhaust pipe so he removed the muffler and stack and it is now under 13'6" , stacks on the Kenworth are 12'4" so it makes the load appear tall. Should I take this off the introduction forum? 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72781-r700-venture/#findComment-530275 Share on other sites More sharing options...
mowerman Posted April 29, 2023 Share Posted April 29, 2023 Interesting with the Cummings motor the breather is usually square I had a western myself my doors were aluminum . That’s terrific that it runs good for you. You must be foaming at the mouth to get it to your place. I know we all would be ha ha..
