B71 Transmission


Recommended Posts

I am looking at buying a B-71 with a 200Hp Cummins and a 10 speed roadranger. Everything seems original in that the truck hasn't run in about 20yrs, and the trans is covered with as much grease and dirt as the rest of the truck, and the owner said the trans was original. I have checked at the old macks site, and while this transmission wasn't listed, there is a disclaimer at the top of the page stating that not all transmissions and models may have been listed. There were only 522 B-71s made from 1953-58. could this be a custom ordered truck or was the roadranger just swapped in.

The reason you didn't see that transmission listed on the OldMacks site is that a Roadranger is not a Mack transmission, it is a Fuller transmission (now known as Eaton Fuller).

Yes, it's possible the truck was built with a Fuller transmission if someone spec'd it that way.
