Photo I found of a Yellow Transit Freight Lines EUHT in the Yellow Dallas shop mid 1940's. Little bit before my time at Yellow.

You mean volvo,there isn't a true mack anymore, no mack manual too reliable I guess

So what do you think is wrong with this trans? Should I pull the top cover and inspect the shift bars? Can the button come loose and slide on the bar causing it to be able to change range in gear? It is a dump truck and of course it has dual stacks so pulling the cover is a chore in itself.

Well, she's long gone and I have a much better one now. After that conversation at Macungie, I figured I'd put together an outline and build on it from there. Shouldn't take too long, at least not as long as the restoration did.

Matt, That was about the time I joined both organizations. I would say it is time to put your wife (just saw the word ex) back to work and write another article for both magazines. 😀 When I spoke with Darin, via email, about him writing an article about Dean's LJ truck after I sent in the pictures of it at the Dark Corner show he sorta bounced it back at me to write the article.. A project for me this Fall???

There was actually an article on the original find in Double Clutch magazine around 2002. My ex-wife wrote it and submitted it. When I was checking in when I arrived at Macungie, one of the editors grabbed me and asked if I could do a follow on article about the whole restoration to submit. It's been 23 years since that original article, so I must've set some kind of record for actually completing the restoration. A real "I'm going to restore that truck one day" story that did get done and not rot into the ground.

Actually the pioneer -anthem combo addresses a problem that mack had for years . The pioneer has a 125"bbc which is about the same as a cascadia or international LT and paccar highway aero trucks. The old Anthem was 116'"i think . Now the new anthem is 113 which is the same as a short hood cascadia - western star 47X setback axle is short and ugly like the new anthem and alot of bulk and fuel haulers buy them. Mack now has more options than before for the highway segment.

ya catching a knock early will save alotta heart ache,,,good luck,,bob

Sorry to hear bro ! Unfortunately your in the years where they may have been experimenting with two piece pistons pull the pan and up root the pistons! This first try at this didn’t work well for mack you may have a broken piston skirt !The lash you show in the second vid is normal on an engine brake engine! Let us know what you find!😡

If Mack cant help, a skilled radiator shop should have all the lines and fittings to build what you need. Just drive it there for them to measure, and figure the angles..

Is it not picking up fuel? If so, how about looking at the fuel delivery line. It may be breaking down inside and clogging the flow if fuel.

High pyrometer temps (1100+) and low boost mean not enough air. My e7-350 went from 1200+/22psi to 900/35 when I found/replacedy cracked CAC.

Need further assistance with my truck shutting down on hot days. Antifreeze, diesel and timing sensor on diesel pump. Speed sensor were all swapped new. Cables connected to speedometer and diesel pump were reinsulated since it would shut off when shaking them. Truck doesn’t over heat or low on coolant when it happens. Mechanic is now saying diesel pump but even he isn’t sure.

Not trying to swindle you, but if you want this book I will sell it to you for $60.00, which includes shipping. I have 3 0f them, along with a dozen other books on trannys and drive lines and rear ends.. and have been wanting to sell some of them off. P.M. your info if you want to buy the book. I can still try to post pictures, but not sure how it come out..

So at the weekend my engine in my cruiseliner starting knocking. I’ve started stripping the engine and found a few things so far Video.mov Video_1.mov

Thanks, Hopefully the new owner saw it.

Got the last 6 of the Vin?

Hello, I have a strange issue with my 2013 Mack mru with mp7 engine. I was pumping in the rain and truck try to kill four different times. Rained stop no problems came back to shop. Getting a pid94 fmi 7 code. Pulled truck up and degreased around fuel filter area. Try to start truck it crank and ran about 1 minute and stalled. Would not start up. I took my blower and dried the whole drivers side engine and then it started right up. So is there a sensor issue or wiring intruding water that would stop truck from starting. Just trying to get an idea where to start looking. Thanks

That would be too bad about ending the 650/750. I'm seeing more of them around this area even among fleets.

Ok it will be after 4.

Any pics would be greatly appreciated sir!

Don't forget Autocar. Their conventional is interesting.

my guess is that 3/4 + 7/8 are the same shift fork and therefore the same rail. There should be a detent in the rail that will activate the shuttle valve as you pass through neutral. I need to post pictures for you, from my book, as well as get the correct description of the parts im talking about.
