MAINTENANCE OF M939 SERIES VEHICLES - OD1661 - LESSON 1/TASK 1
(1) Differences. The only difference between the M929 dump truck
and the M930 dump truck is that the M929 does not have a front winch
and the M930 does.
This difference affects the following:
vehicle
length, vehicle weight, shipping dimensions turning radius, approach
angle, and special winch-assisted operations.
This difference does
not affect the purpose or performance of the vehicle.
(2) Purpose of the Vehicles. M929 and M930 dump trucks are used
to transport various materials.
These vehicles operate with load
limits up to 20,000 pounds on the highway and 10,000 pounds cross-
country.
Fully loaded, these vehicles can tow trailers with
additional loads up to 30,000 pounds on the highway and 15,000 pounds
cross-country.
Each vehicle has a welded-steel dump body.
The
forward end of the solid dump body extends up and over the vehicle
cab to protect it from damage during loading. Both use a troop seat
hit for troop transport operations.
The M930 is equipped with a
front winch.
This feature makes it more versatile under difficult
field conditions.
(3) Performance.
Under maximum loads, M929 and M930 dump trucks
climb road grades as steep as 17.
Without trailer loads, they can
handle grades up to 30.
Maximum speed is 54 miles per hour.
The
vehicle can ford hard-bottom water crossings up to 30 inches without
a deepwater fording kit and 78 inches with the kit. Both trucks are
equipped with dual fuel tanks.
This extends the cruising range of
the vehicles to 400 miles with loads and 480 miles empty.
The
turning radius of the M929 truck is 35 feet 6 inches.
The turning
radius of the M930 truck is 36 feet 6 inches.
The vehicle has no
special limitations.

Tractor Trucks:
M931 WO/W and M932
W/W (figure 5
on the
following page).
(1) Differences.
The only difference between the M931 tractor
truck and the M932 tractor truck is that the M931 does not have a
front winch and the M932 does.
This difference affects the
following:
vehicle length, vehicle weight, shipping dimensions,
turning
radius,
approach
angle,
and
special
winch-assisted
operations.
This difference does not affect the basic purpose,
performance, or special limitations of the vehicle.
