Table 7
- Chassis Friction Horsepower. Use applicable power
unit GVW (to nearest higher, 454 kg (1,000 pounds))
and the engine speed (to nearest 100 rpm) which is
required for 69 km/h (43 mph) geared speed. For
GVW and engine speed beyond the range of this
table, factors shall be extrapolated.
Table 8
- Grade Factor. 0.75
Table 8A
- Correction Factor. Not required.
Table 9
- Road Factor. 0.0
6.4 Weight distribution, GAWRs and specified GVW vs GVWR. All users of this
specification are cautioned that the provisions of 3.1.7 make it highly likely that a vehicle with a
gross vehicle weight rating (GVWR as opposed to the GVW specified herein) equal to the GVW
specified herein will NOT meet this specification unless front and rear GVWRs are specified
under 3.1.7.1 and, thus, 3.1.7 does not apply. The Government intends to load vehicles to
specified GVW with a uniformly distributed payload. Thus, unless an ideal (and highly unlikely)
relationship between the center of gravity of the load and the front and rear curb weights and
GVWR exists, such a vehicle inevitably will be overloaded on the front or rear and will not
conform to contract requirements.
6.5 Spare tire carriers. Requisitioners, users and procuring activities should note that a
spare tire carrier on truck tractors and dump trucks of necessity increases the wheelbase of the
vehicle to what many consider an unacceptable length. It is recommended that truck tractors be
procured without a spare tire carrier, with the spare carried on or in the semitrailer the truck
tractor will be pulling. On dump trucks (and dump stakes), it is recommended that the spare be
stowed on the dump truck for shipment and when needed after the dump truck is placed in use,
that a wrecker be dispatched to the disabled dump truck, carrying the proper spare.
