Popular Post BOBWhite Posted April 19 Popular Post Share Posted April 19 (edited) I've been apart of your group for way too long now without a Mack truck, that is until today. I got a 1972 RS700L with a 283 Tipturbine, twin stick 5+2, and a grain box on the back. The owner extended the frame and swapped out the original V8 due to leaking liners and no parts (the door tags are gone so I have no way to confirm this for sure). The 283 engine runs very strong with no blow by and plenty of power! couldn't be happier! Never driven a twin stick so I'm still getting used to that, I just left it in direct the whole drive home but I'd imagine with 750 bushels on the back I'll need em. She drives like a dream! No squeaks or rattles, just smooth even unloaded. I've got lots of questions though! Much more to come!

BOBWhite Posted April 19 Author Share Posted April 19 (edited) My first question is tell me about these air cleaners, I've never been around them. Can you get new ones? I don't really want to put a canister on it I think it looks cool the way it is Edited April 19 by BOBWhite 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75434-back-in-the-mack-pack/#findComment-574003 Share on other sites More sharing options...
Popular Post Geoff Weeks Posted April 19 Popular Post Share Posted April 19 If I am not mistaken, that is a Farr aircleaner. open and count the tubes across and down and get that size element. They were more of a "construction" equipment air filter and often were tied with an "aspirator" on the exhaust to "knock" the bigger dust particle off and blow them out with the exhaust flow. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/75434-back-in-the-mack-pack/#findComment-574007 Share on other sites More sharing options...
Geoff Weeks Posted April 19 Share Posted April 19 Filter should look like this on the inside, It appears the Farr of old has been acquired by someone else and is no longer made. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75434-back-in-the-mack-pack/#findComment-574008 Share on other sites More sharing options...
Bullheaded Posted April 19 Share Posted April 19 Awesome truck! Hope you can find air filters and keep it original. A lots of Autocars around here used to use those Farr air cleaners. So are you going to be working it? Quote Link to comment https://www.bigmacktrucks.com/topic/75434-back-in-the-mack-pack/#findComment-574015 Share on other sites More sharing options...

Popular Post terry Posted April 19 Popular Post Share Posted April 19 That’s probably a x107 six speed, auxiliary goes in direct and just shift the five speed, reverse is on the auxiliary stick, a bullet proof transmission.

mowerman Posted April 19 Share Posted April 19 Wow, congratulations that thing looks really clean, but I thought you had an MH what happened to that? . Good luck I’m sure you can find your parts. Breather elements are relatively easy along with most other filters check Amazon that’s where I got my oil filter. Good luck with it and have a ball….

Bob We sold that MH to my uncle years ago but I think he is still using it. checked the air cleaner part number today, Wix 542589 and found one on Amazon for pretty pricy but better get one primitively. Its probably be cheeper to convert it to canister but I'd imagine they'd have to be huge for all the air the tipturbine needs. Wow that tip turbine is LOUD once it gets going! I'll need earplugs if I work it all day. 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75434-back-in-the-mack-pack/#findComment-574072 Share on other sites More sharing options...

Our other truck with the 1693 was pretty rough starting last fall and it's pretty tired with a dropped liner, plus think this Mack will get double the fuel economy. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/75434-back-in-the-mack-pack/#findComment-574073 Share on other sites More sharing options...

BOBWhite Posted April 19 Author Share Posted April 19 My next question has to do with the shudders as I don't really know how they work. Are the actuators still available if this one Is bad? What temp should they open up? The temp gauge is not hooked up/can't find the wire so that's the first thing on my list.

mechohaulic Posted April 20 Share Posted April 20 feedline to the shutterstat should have a 1/4 turn brass valve in line . close the air supply ; shutters are suppose to stay open . will allow for running the unit plus give time to diagnose system. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75434-back-in-the-mack-pack/#findComment-574080 Share on other sites More sharing options...

Popular Post Geoff Weeks Posted April 20 Popular Post Share Posted April 20 (edited) I could be wrong, but I believe that is the type of shutter that is fully mechanical. It uses a "wax pill" to operate the shutter. No air involved at all. The temp setting should be the same as the thermostat, as the sensing unit is in the bottom tank. Somewhere I have the info on them, as I have that type on one of my Fleetstars. One of the things I remember it saying is "DO NOT FORCE" the shutter or you can damage the "pill". On mine, all I had to do to get it working is to take apart the linkage and paint with graphite paint.

Popular Post Geoff Weeks Posted April 20 Popular Post Share Posted April 20 Yeah, I found the instructions for them. If the engine has a 180 deg stat, the shutters should open when the bottom tank is at 180 deg, engine should be at 190 at the top outlet hose. Shutters don't open to full 90 deg on the shutter "blades" only go to about 45 deg open. Fully mechanical so any rusted linkage will jam the operation. I can see two nylon bushing in your linkage cross shaft. Just make sure it is free to move but don't force the actuator. If you need more I can try and scan the pages, but yours looks functional. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/75434-back-in-the-mack-pack/#findComment-574090 Share on other sites More sharing options...
