Mack NM 6 Ton 6x6 Truck (G535)

The combat "N Series" were the first military 6x6 trucks by Mack. The NM-1 (87 built) appeared in early 1940, followed by the NM-2 (107 built) and NM-3 (104 built) all with enclosed hard cabs. The NM-5 through NM-8 did away with the metal cab, replacing it with the military soft canvas top. There was no NM-4 produced. The arched front bumper -- to clear a pintle hook -- first appeared with the NM-3. Approximately 10,000 of these trucks were produced in total.

The engine for the Mack NM 6x6 trucks was the 6 cyl. 707 cid Mack EY, that developed 159hp@2100 rpm and provided 530lb-ft of torque@1000rmp. The transmission was the 5-speed Mack TR36 and the transfer case the 2-speed Timken-Detroit T77. The truck had a net weight of 22,659 lbs., could carry almost 10 tons (never mind the 6 ton rating) and could tow 30,000 lbs. such as field artillery or ammunition trailers.

A Gar Wood capstan winch was mounted behind the cab. The cargo body was steel for the NM-1 through NM-3, then wood.
