Figures. you will have to go testing to find what each terminal is for. once you know what terminal does what hook it up directly to the sending unit and test the range of the gauge. if it works normal hooked directly to the sending unit. then I would test the wires in the truck. you may have a bad ground,signail wire, or hot, hopefully its just a louse plug...

Yes you can but I think the problem will be if you louse the trailer or a air line the flip style valve will not "pop out" to contain service air in the tractor?. IF you can live with that then all you should need is valves that will exhaust when you set the spring brakes. the other issue is it may not be DOT approved if you need an inspection?

Yea Barry and the Watts mack team has given us the best Mack website to share and learn from. Seams like just yesterday I was on the old BMT MSN site. thinking about it now and its been about 10 full years now that we have had a place to talk about Macks. Thanks Barry!!!!

does the gauge have a ground to it? I know on the R models the fuel gauge needs a Hot,ground and signal wire. Lookig at the back of the gauge it should have I,G,S (ignition, ground, signal)note make sure they are all connected and the ground is clean. If you can remove the gauge wire it up next to the fuel tank and test it by moving the float with you hand. If it works normal like this this look into the trucks wireing for the problem. Trent

you will get a hop with a warped clutch. think of it like a warped rotor. if any of the clutch plates are warped just slightly it will try to bounce. if you are in to high of a gear it will do this. Will also get a bounce from wheel slip if the powerdivider is kicked in. dont feel bad about getting stuck in the snow. its very easy. I got my tractor stuck this morning in its parking spot. Got a whole 3" before it slipped and dug in. had a wheel locked up so that dident help. It took 15 mins of rocking it back and forth to get it off of 2" of snow. Loaded your pretty much good to go but bob tail or empty good luck on any hill if you stop.

never mind found a kit that has the sender with misc unions that allow you interchange thread sizes. found them for $16 online. Mack Wanted $55 each and that was with "D" code LOL!!!!! Trent.

ok Picked up the new oil temp gauges tonight. Saw under the lens that they are MFG by Teleflex. Did a search and came up with this page with the sending unit info http://gfretwell.com/electrical/teleflex%20senders.pdf says I need a type E sending unit. (SW style) for 140-320 F gauge. next question is what thread size is the most common on the block,trans,and rears? I remember seeing some ports with plugs in them but Im not up on the thread size. anyone want to take a guess or know off the top of their head. these are the 3 sizes 1/8 NPT 3/8 NPT 1/2 NPT

Bears vs Packers 2pm sunday... Im holding my breath for further comment. In the mean time this is for all you Packers fans.....

NO but I could use that towel right about now

yea thats a good idea to get the sleeve cold so it drops in. just hope the injector hole dont get to tight with it? Over at the railway museum they have to sweat the steel "tires" on the steam locomotive wheels. they have this huge flame ring to heat the steel tire and then they have to quickly drop it on the wheel and hammer it down into place before it cools. Kinda cool to watch.

Just googled her name and she sure was a good looking girl for her day. Im digging her "top heavy" style LOL

Yea. I had made a comment the other day about how silly it is trying to up load a pic. Seams the system cant size it or if you post more than 2 they remove them and put them up as a link only. I feel that when ever were trying to show off or show some pics of trucks you have to go back in time and do it the hard way. I like to open a web page to surf the new content and have the pics pop up as its loading. Its why I rarely link pics over there. to much BS. I will search for Truxnut and will send him a PM

I like the ATHS site better than the old one but think there is much better ones out there. I noticed Frank Surber does not post as much either? John evans, Bill D and a few other names I cant think of are MIA. to bad because When I first joined they had alot to offer us with their rich trucking background

must have missed that day on the ATHS site. what was that all about? John was a great guy was wondering where he went? hate to see the good ones leave.

Last few evenings after work I have spent at the yard redoing the interior of a friends Mack Superliner. Got a nice warm bay to pull it into to work on so its esay. Last night I had Removed all the Door handels, interior panels,headliner rear wall etc... put them in the corner of the shop so I dont louse them. Night was over cleand all the tools up and got her ready to park outside. I Jump in the truck,start it up and back her out. Park her in its spot, set the brake,turn the key to off,pull the throttle stop and kill the big v8. Great. Reach for the door handel..oh um its not there.......... and neither is the other side. oh..*&^%... no window crank hanels either? Ok. vent windows open! crap.... my fat arm can reach the out side door button!!! OK So im sitting there for a min thinking how in the hell did I just do this to myself. look on the floor for anything that I can use to turn the square door handel stub. Nothing, Try and open it with my hand un my pants pocket, nope the keys and tried to sandwich the stub and turn it, nope. So Ireach in my pocket to get my phone to call for help. fumbeling in my pockets I pull out a phone,dollar bill,some change and a 3/8 open end wrench that I mistakenly took home from work. Guess what. that 3/8 wrench fit the square door handel stub like a glove. turn it and Im free! I get out looking to the sky. "THANKS DAD! or whoever told me to take that wrench home". I have locked my self out many of times but never in! Guess there is a first for everthing!

bump!

I have spread a few loads but I always unlock the gate before lifting. To many times Have I seen a stuck gates and even a few "rocket mans" from a box that was raised with the gate closed.

always liked the looks of them. Kinda like the DM version of Brocakway. Were these the same models used in the Die hard movies?

I see the problem. Yea you need to have a PTO that runs off the Engine revs so that when your in Gear and moving forward the more throttle you give the faster it lifts the box. right now your running the PTO off the transmission gear speed. so when you grab first gear the box is rasing too slow even at full throttel. With the PTO running off the enge RPM You would still use 1st (or 2nd gear) but a properly specd PTO will lift the box faster. PTO gearing will depend on the trans and what kind of pump speed that is needed. TO fast of a pump can blow lines and snap a PTO shaft,gear etc....

Picked up 4 oil temp gauges and have a few questions 1st I need to find sending units for them. My local dealer said the sending units are more than the gauges? (about $55 each) dont need $200 in sending units! anyways does anyone know who makes the mack gauges so I can call them up or does anyone know the ohm range for them? this is for engine,trans,FR tandem, RR tandem oil temps. single wire sendng unit 2nd where are the common locations to instill each sending unit? Trent

never seen that kind of hitch but if you can remove the towed trucks without the need of a machine that would be faster and you could drop it anywhere. that Oshkosh looks like the fleet of Cement trucks that Meyer ran in the 90s. I think they still have a few left. Strong runners and put their DMM macks on a level playing field. I always thought they would be a PITA to see out of with the big hood and sitting that high up? I can rember seeing them all day long near my house.

hard to say.... If im selling something I like to take the first person with cash as he is standing there willing to give me what I want. Some times buyers get cold feet and change their mind in a matter of 5 mins. On the other hand If I said come look at it tomorrow I would not set up any other meetings for other lookers untill after you came to look and made an offer. Trent

Not sure if I follow the question either? sorry... I understand what you want to do is spread a load but dont follow why its not working to your liking? I will take a guess and say that the PTO speed is to slow and the box does not raise as fast as you need it to spread the load?

HA HA... thats a great story... Bet you and the parts guy wont ever forget that one!
