Fellow board member selling a 350hp pump off a 4v will it bolt up to my 2 valve and should just a pump net me more hp?

I will say that there were a few members that just had to put down just about every mack pic they saw. I was cool with a joke every now and again but it started to seam that some of the members could always talk down to a mack owner but if you dare mention any thing about another make of truck the internet police would chime in. but I guess most of us know that every make of truck had their good and bad. I might check out JOT tonight just for kicks...I really do miss the old ATHS members that would share their wealth of info. it seamed that there was always a few good members that had info on specific stuff. It was very helpfull to have that when I was working on off breed trucks.... I have to say we are very lucky to have Barry and Watts mack letting us use this site how we please. Very limited upsets and we just kind of run it on our own with the pleasure that the mods dont need to police us. We have the off topic and VIP aera where you can show off your inner demons yet keep it clean out in public view. Were all a little odd in our own ways yet our members here have shown the most respect for others than any other board I visit. No Political correctness crap and we just drive this ship like the old school drivers were back in the day. I know the members here have helped me dearly in my time of need and im very thankfull for that!

Havent been on aths site in over a year...I heard some of the old school members on the ATHS fourm had started a new forum with no more bull shit. Is that true? Is it still up and worth the time or is it the same old PC garbage as the last forum became? Just wondering

What would you say the model designation is for this truck? A R600 is a standard hood. A R700 is a standard long hood.... Maybe a R007 because this is a reversed long hood? Lol

We recently repaired a crack in a 1996 international otr tractor. 500k miles cracked dead center above the front axel. Top rail flange was cracked and raised up 1" ....looked like it pinched the rail and the tension pushed the flange upward. We added a inner channel as far forward and aft as we could before getting into big bolts. About 8" either side of the crack. We drilled a hole to stop it spreading,welded up the crack and it's held for the last year with no trouble. Yours will be a little more intense of a repair in that area and the way Mack frames are up front....

What are you asking for the pump. Known or aprox mileage?

Ok here is how I did mine... Remove horn button and nut, soak in penatrating oil. Now Remove doors, hood,fenders,seats, floor boards, gear sticks. Use a back hoe to lift cab off frame. Careful to not bend steering wheel. Now use engine hoist and steering wheel puller to remove wheel....simple

Pretty cool. Steel dash small cab. Looks like a Hendrickson front with a hood off a rd800

$10,000 with a cracked frame.... What a deal...

Is r jones a big company. Only seen that r and a Pete 6 wheeler... Look at the arrow truck. It has the old school green clearance lites up top...

I thing grand rock does that but I'm sure it's pricy... Did you try a local muffler shop?

It should be plumbed into a port in the intake manafold or at some place in the piping between the intercooler outlet and intake manafold . this gives you the true boost reading after the air pressure drop thru the intercooler. Also check the line for kinks or oil blockage. that can give false readings as well

well with 8lbs of boost and no smoke you either have a bad reading on your gauge or the fuel is cut way back and it will not be pulling like it should. just running down the road at 1800RPM and not throttel its pulling 2psi. as soon as you touch the pedal it would jump up to around 10-15 psi under normal cruiseing speeds

IIRC you should see about 23-27psi ... does it blow black smoke, low on power? look for a large boost leak in the system

love that long,tall, chrome, single stack.

If you can't find one do what I did and buy a carpet mat with a rubber back and cut it to size. I made mine nicer than stock and the cut outs are perfect. got my mat from u line I found a local lady that was going to sew in a Mack emblem but never to around to it. I had little luck finding oem carpet in good condition and a hole that as in the correct place for my gear stick...

I have seen that r jones r model about 100 times and not once did I see it dirty. I swear he has the truck washed after every time the tail gate slams shut........

The guy I bought this trans from had this one rebuilt locally in NJ and was sitting in his shop as his spare. His fleet of R models had 12 speeds and his currect truck was a late 90s cl with a 350 and 12 speed. His CL was air shift with a dash switch for lo lo... He said he had pulled it out of a truck when he had some issue, had it rebuilt, then sold off most of his fleet. He just held onto this incase his cl trans went down. His cl had the plate with the air valves mounted to them but hat and the stick were not part of the sale....I will have to see if I can locate the valves and air cyl to complete the set up. I already have the selector valve on the stick...

ok thats what I thought. I guess I can use the 2nd stick for now and convert it later....thanks for your help!

bottom of screen....."REPLY TO THIS TOPIC" THEN LOOK AT THE BOTTOM RIGHT..."MORE REPLY OPTIONS" CLICK THAT . bottom left of screen it says "attach files" next to that click Browse. find and click on the file you want to upload from the computer, "then click attach this file" you should see a small pic/file size if it uploaded. hope this helps

Reason I ask is I called up Global truck traders a week ago and bought an air shift top cover and the sent me the rear cover. I likely mispoke so I will keep this rear air top cover they sent as a spare. either way I just need to know what goes over the other hole as all I had ever seen were single stick 12 speeds. thanks for any help!

the case is stamped TRTXL1070B so I would assume that I have the later single stick version? im wondering if just a cover goes over the hole where the 2nd stick would normaly be? I think on the early version the 2nd stick just put the trans into low low. With the later single stick version they just put a air shift control for that hole?

also.... will my stick on my 6 speed bolt up to this top cover?

In this pic of My 12 speed can someone tell me what is installed over both of the holes that the cardboard is keeping dust out. I know the one hole is for the stick but the other has me stummped. I thought one of the holes has an air shift? Thank you

That's a good idea. Never thought of that...
