ENGINE
- Provides power for the vehicle.
LIFTING TIEDOWN SHACKLES
- Used for lifting the vehicle in ship-to-shore operations and for
tiedown attachments when transporting vehicle.
FRONT WINCH
- Used for recovery operations, powered by a propeller shaft extending from
transmission power takeoff.
PRIMARY FUEL FILTER
- Filters contaminants from fuel.
AIR CLEANER
- Filters air before it enters the intake manifold.
TRANSMISSION
- Transmits engine power to transfer case.
FRONT PROPELLER SHAFT
- Transmits engine power from
FUEL TANK
- Stores fuel.
transfer case to front differential.
REAR PROPELLER SHAFT(S)
- Transmits engine power from transmission to transfer case and
then to rear differentials.
REAR BOGIE
- Suspension system that supports rear vehicle weight.
TOWING PINTLE HOOK-
Permits towing of vehicles or equipment.
REAR DIFFERENTIALS
- Transmits power from propeller shaft to axles.
AIR RESERVOIRS
- Storage tank(s) for compressed air.
SPARE TIRE CARRIER

TRANSFER POWER TAKEOFF
- Supplies power to drive pump for water and fuel tank vehicles,
earth boring auger, and rear winch.
TRANSFER CASE
- The two-speed transfer case along with five forward speed transmission
provides 10 speed ranges to front and rear differentials.
AIR-HYDRAULIC CYLINDER
- Air-hydraulic cylinder increases fluid pressure to the wheel cylin-
ders. The wheel cylinders expand and press the brakeshoes against the drum to slow or stop the vehicle.
MASTER CYLINDER
- Stores brake fluid in reservoir and supplies hydraulic pressure to displace
fluid into the brake system. The master cylinder also compensates for seepage from the system.
TRANSMISSION POWER TAKEOFF
- Supplies power to drive front winch on all vehicles. Dump
vehicles have a double-ended unit on left side of transmission. The forward output shaft is used to
drive front winch. The rear accessory drive shaft drives the hydraulic pump for the dump vehicle.
SECONDARY AND FINAL FUEL FILTERS
- Filters fuel from primary fuel filter before fuel
enters fuel injection pump.
