I have 3 air switches on my dash. PTO,tailgate, puff limiter all are of the simple lever style. I took them out of a wrecked pete at a junk yard

WOW That RS/RL is from my town but I have never seen it before! I think the owner owns a Superliner now?

just like the guys that still say a no power sterring truck is no big deal in the city. I had my RS for 1 year before I converted it to PS!!! those city jobs just killed my arms!!! When I bought my first B model the guy dropped it off with a mechanical detach. It worked fine to detach but lots of BS to get the pins back in when hooking back up. Im shure it was the best of the best back in its day but times have changed. Trent

Yea Herb same way here in the city, Heard many old storys of crews leaving the boom on and letting the operator and truck driver do there job. I have moved a few machines where the operator just sat in the cab and we went a few miles down the street. of corse this was on a sunday morning or a back road away from the fuzz.

Larry, when ever you need a new trailer to haul your dragster around,Ill set you up with a real nice featherlite simmilar to this trailer, just dont worry about the price we can talk about that later LOL just get all those springs back under your B Trent

I like to just set the idle RPM up to the pont that it lets the oil press get up to 45-50 PSI. I think this is around 800-900RPM trent

yea we need to know you rear end ratio to give a better idea if it will work. The 2070 has a real big Overdrive. most Macks I have seen with 2070s had slow rears ...5.55-5.73 etc... the 12 speed dose not have as big of an overdrive. so if your rears are to slow your top end will be to slow 45-50 MPH etc... then again a "standard RPM" 300 pump could get your RPMs up to 2100 and get your top end back. Most will say The 12 speed is a great trans, one of the better ones mack offered in the R model. you can drive it like a 5 speed or split the gears to pull a hill and still. have 5 reverse gears when backing. oh and the Low low hole will still let ants pass you up LOL Let us know the rear end ratio trent

I work full time at Carl Haas Auto Imports. the same owner runs his parnerships Newman Haas Lanigan IRL team out of the same building . My main gig is to rebuild dampers and drive one of the 4 trucks to the race tracks. Its still fun to travel if I run alone but the traveling is getting old. I would say its better than hauling freight but like anything it gets old with age. This year my scedual has been very relaxed and have spent all summer home. I needed the brake from the road so im not complaining. THE IRL has about 20 race weekends. I would never want to run with the nascar crowd. not just becasue I dislike the cars but the 40 some odd weekends that they race..NO THANKS!!. I will be back up in RA later next weekend for the ALMS and Atlantic race. If anyone is up that way let me know.

Herb, I tried covering up the chicago accent but I think my slicked back black hair and dark sunglasses was a shure giveaway that I was not a local LOL!!!

Had to haul a Champ car trailer From Road America raceway in Elkhart lake WI back to the chicago burbs took a few pics of the truck a the oasis and back at the shop. Not a bad combo in my opinion new million dollar trailer with a 30 year old truck. Lots of looks at the track and on I-94 heading home.

I have seen a few mid 70s R700s with V8 detroits but never any superliners I have heard there were a few made. Most superliners I see have the std mack 6 or v8 mack, a few with cats and alot with BCcummins Trent

Truck,car,bike and train show at the IRM http://www.irm.org/ lots of vintage machines to be seen all in one place. you wont be dissaponted Trent

an air to air will have likely 2 times more cooling fin surface than the charge air cooler box does. As said above,The tip turbines were good for there time but todays air to air is more efficent. If you want more boost, faster responce etc.. find a diffrent turbo. if you are working the truck dont get to crazy with a diffrent turbo set up. you may louse performace where you need it most? Trent

Grease any zerks on the stering first. If that does not help it could be that your low on PS fluid? if the pump cavatates the oil it may make a high pitch vibration that sounds like a howl? or the steering box is forcing the spindle to contact the stops and the pump is fighting the stops? start with those

1600 seams low for such a large engine However I guess it was big power for its day. I guess it makes it up with the HP? I have only driven a few DD 2 stokers and they never felt like they had much power. just alot of noise and alot of gears needed to make the noise LOL

Rob, I think Skip is talking about the lightweight LT mack models "LTL" Sounds like your having fun with the trucks. Cant wait to see how it turns out. I would love to get a E9 V8 under the hood of the RS but fuel costs would have me worried. not to mention having to change the trans and driveshafts to get it all in properly. Whats the TQ rating on the DDV12s? Trent

if the truck has a E7 and front mount intercooler I see no need to go to a tip turbine. Only reason I would see the use of a Turbine set up on an E7 Is for fitment issues in a smaller truck. I think the 4V E7 manafolds are a little diffrent than the 2 valves? that may be an issue? Trent

If I recall it is a Mack PTO and no longer availible (thats the rumor I have heard) Most common set up was to bolt it to the lower coutershaft. You would need to check your trans to see if it will accept this PTO. There may be a stamp on one of the countershaft covers that notes that the trans will accept this PTO. if still not shure just pull the lower contershaftcover and look inside for splines. I think this was a more common set up for dumptrucks/lowboys etc.. Im not shure of the load rating for this one so check before you go looking. I just like this set up as you can keep the aux in direct or low low when raising the box. the only downside is you only get one PTO speed. Trent

Hey Rob What about the countershaft PTOs for the 6 speed? . Thats what I have with mine and love it. You dont need to have the main in gear and aux in nutral to operate it. just flip the swith and it starts pumping Trent

THE DUMP BOX IS WAY TO SMALL FOR A MACK:P

if the price is better than having stock ones repaired than this is a great option! Trent.

Barry whats the price we are looking at here? Thanks trent

You mentioned that you idle it alot. that may be the issue as well? If oil is getting past any seals in the exhaust or unburnt fuel is puddling up with carbon buildup it will shurely smoke. Like Rob said Give it a good pull and get the exhaust hot. that will burn off the oil and fuel trapped in the exhaust. trent
