M-746 Heavy Equipment Transporter (HET) Truck Tractor, 22 1/2-ton, 8x8, (G-903)
The M-746 Heavy Equipment Transporter (HET) is a Heavy duty vehicle intended mainly to evacuate a disabled main battle tank or other disabled vehicles of similar weight and dimensions. Its design is suitable for primary or alternate main supply routes or from vehicle collecting points or maintenance units. Secondary missions of the M746 include the transport of non-disabled tank vehicles over extended distances and general cargo missions. The M746 HET Truck Tractor commonly was paired with the M747 Semi-Trailer, Low Bed, Heavy Equipment Transporter, 60-ton.
After development by Chrysler, the M746 HET was manufactured by Ward LaFrance Truck Corporation from 1973-1977. Total production was less than 200 units. The M746 HET was replaced by the M911 Truck, Tractor, C-HET, 8x6.
The M-746 tractor vehicle is also capable of winching and towing operations. The cab accommodates a driver, assistant driver, and two additional crew.
To increase maneuverability of the M-746 8x8 tractor, the tandem front axles steer. The front and rear suspension are taper leaf-spring bogie type with shock absorbers and high-flotation tires.
Manuals for the M746 vehicle will be in the TM 9-2320-258-xx series, where the xx represents the maintenance level. The M746 tractor is identified by NSN 2320-00-089-7264.
