1942 Mack FJ

Mack TR-15 with TRA-12 Auxiliary

Truck Information:
In 1942 World War II was going on. This 1942 Mack FJ was built for the United States Army and it was built as a dump truck. The F-series is a very heavy-duty truck; they are very desirable among truck collectors. It has air brakes, but is still using chain drive. It has a C-cab design that goes all the way back to the AC model starting in 1916. It has a six-cylinder Mack engine and two Mack transmissions; it is all Mack. This truck weighs over 24,000 pounds and its GVW is 50,000. On back is a Jaeger six-and-a-half-yard concrete mixer. Six and a half yards of concrete weighs over 26,000 pounds. On today's mixers the bowl is tilted upward; on here it is horizontal. You didn't fill it through the unload hatch. There is a side hatch that would have rolled around to the top to fill the concrete mix. It has a separate engine to run the cement mixer and there is a transmission for the mixer. You mix the cement by turning the barrel one way, and you get it out of there by turning it the other way. There are veins on the inside of the barrel; when you are mixing it is pulling everything toward the front, and when you are dumping it is pushing it all out the back. It has giant 1200-24 tires. It would have been quite a thing to drive with a full load. Top Speed: 27 MPH
