The major interior components shown below are common to one or more models covered by this manual.
Components not covered here are found in TM 9-2320-361-10 or the applicable maintenance chapters of
this manual.
STEERING WHEEL
- Manual control for turning vehicle.
TRANSMISSION GEARSHIFT LEVER
- Is used to shift transmission into 1 through 5, neutral,
or reverse driving gears. Vehicle must be fully stopped before shifting from 2nd to 1st gear or into
reverse. First and reverse have no synchronizing gears.
COWL VENTILATION
- When open, allows air flow into the driver’s compartment.
POWER DIVIDER CONTROL LEVER
- Used on earth boring and polesetting vehicles for driving
either the earth auger or rear winch on the polesetter. The rear winch direction is reversed with this
lever. Driving power is provided by transfer case power takeoff (PTO). The transfer case shift lever
must be in neutral and transmission gearshift in drive (1 through 3 or reverse).
TRANSFER CASE SHIFT LEVER
- Used on all vehicles to change ratio of driving power to axles
and wheels. Lever is pulled up for HIGH range (greater speed and lower power) or down for LOW
range (lower speed and higher power). This shift lever is placed in neutral to allow the transfer PTO
lever to be engaged while preventing drive power to axles and wheels.
DRIVER’S SEAT
- One crewmember adjustable seat.
TRANSFER POWER TAKEOFF LEVER
- Place in UP position to provide driving power to earth
boring auger or rear winch. The transfer case shift lever must be in neutral to prevent driving power
to axles and wheels before this lever can be engaged.
PARKING BRAKE LEVER
- Pulled up to apply parking brake. The knob at the top of the handle
is turned clockwise to increase brake cable tension.
HINGE LOCK
- Locks transmission PTO lever in neutral (N) position.
TRANSMISSION POWER TAKEOFF LEVER
- Provides two-speed and reverse driving power to
front winch. Neutral positions are used between each drive and reverse positions. Input power is
available to the transmission PTO when clutch is engaged and engine is running. Transmission is
normally placed in neutral (N) when driving power is applied to the front winch.
REAR WINCH HINGE LOCK
- Locks rear winch lever in up (disengaged) position.
REAR WINCH CONTROL LEVER
- A two-position lever to engage or disengage drive to rear
winch. The transfer case shift lever must be in neutral and transmission gearshift in drive (1 through
3 or reverse).
ACCELERATOR PEDAL
- Foot control for determining engine speed.
CLUTCH PEDAL
- Is depressed to disengage engine from transmission and allows shifting to
different gear ratio. When clutch pedal is released, engine engages transmission.
SERVICE BRAKE PEDAL
- Foot control for stopping vehicle.
HYDRAULIC HOIST LEVER
- Control lever for raising and lowering dump body. Driving power to
the hydraulic pump is supplied by the transmission PTO.
INSTRUMENT CLUSTER
- Contains indicators to show engine performance.
