Wheels of Time, May/June 2014 Vol 35, No. 3 (article titled Big Guns & Liberty) has the definitive information on the Freedom series trucks. ATHS has the issue in their members area archives. The Freedom edition was to be limited to 200 trucks. I was only able to identify 151 chassis records at the Mack Trucks Historical Musuem. 22 of the 151 trucks were the MH 613 cabover. I was able to identify 129 SuperLiner II trucks.

Look at my article in the May/ June, Vol 35, No. 3, Wheels of Time, for the story on the "Freedom" trucks. As far a I know there was never a "liberty" edition of the SuperLiners.

Like most post here - this has strayed a long ways - Attached is a scan from the dealer price manual for my B75. Looks like three choices were 5, 8 and 12 ton. Prices were quite reasonable. The sheet just lists them as "jacks".

Fixed. It was a combination of a bad air switch (the one behind the primary fuel filter on the treadle valve) and an open circuit between the two brake controls on the dash (maxi and tractor parking brake buttons). Thanks for the suggestions and to Josh.

My truck has no brake lights when stepping on the service brake pedal. The turn signals work (and 4 way flashers). The blue tractor brake button activates the brake lights, the yellow maxi brake yellow button also activates the brake lights. All of the lights - marker, service brake and turn signals lights work thru the trailer connection. New trailer lights air switch, new Signal Stat turn signal switch. The wiring diagram for the truck shows a "service stop light switch". Anybody know where I can find where that switch is physically located? It is not the one located under the floor pan to the rear of the primary fuel filter. Any help??

Bad News: The early Australian Mack records were disposed of into the dumpster during one of the many changes in Mack ownership; Good News: The records were saved by a private individual and are still in existence and may be available.

Just to be clear: Changing the polarity of the wiring to a Mack 12 (or 24) volt starter will NOT change the direction of rotation.

Some of the information above is wrong. A starter will not change direction of rotation by changing the polarity.

This has what to do with: Antique and Classic Mack Trucks General Discussion

Look in the Wiki section of this site. They may still be accessible. If not, pm me and I will try to send them to you.

Would you mind saying what the parts cost for this project was? If you don't want to post it - just send me a private message. Thanks

Send a request to the Mack Trucks Historical Museum through their website with the information from the tag. They have an amazing set of records - the fire truck section has hundreds of thousands of blueprints. I am not sure what the wait time is right now but is will take several weeks to get a complete package on your truck. No charge - donations accepted

"ENDT 673 in cold weather" is the header on this thread. I am not arguing with anybody about where to hold the foot feed - just showing what the Mack manual says about starting an ENDT 673 engine in cold weather.

That sticker sure isn't for any of the ENDT 673 engines. The same book shown above, Form No. TS-442, shows an operating range (rpm) of 1,500 to 2,100, idle speed 550 -575. Governed speed: full load 2,100, no load 2,350. Load it up heavy and lug it down to 1,020 rpm, it will be fine - for a short time, then stop and replace head gaskets.
