MAINTENANCE OF FORKLIFTS - OD1660 - LESSON 1/TASK 2
crankshaft pulley.
The transmission oil cooler is located in front
of the radiator.
The radiator is equipped with a coolant recovery
system.
(5) Electrical System. The electrical system is a 24 volt system
with negative ground.
It includes an engine driven alternator,
starter motor, instrument panel, light system, and two 12 volt
batteries connected in series.
The alternator is mounted on, and
driven by the engine.
The ignition switch controls the application
of power to the main light switch and the starter motor.
(6) Transmission and Drive Shafts.
The transmission and drive
shafts provide three speeds in both forward and reverse. It also has
a declutch feature which permits it to neutralize the transmission.
The forklift is also equipped with an axle disconnect which controls
the engagement and disengagement of the transmission drive to the
front and rear axles.
Three drive shafts are provided to transmit
this power to the front and rear axles.
(7) Axles and Wheels. The truck has single reduction type axles
and pneumatic type tires.
The front axle is rigidly mounted while
the rear axle is trunnion mounted.
(8) Brake System.
The brake system (figure 15 on the following
page) consists of the service and parking brakes.
(a) The service brakes are hydraulically operated and power
assisted on all wheels.
These brakes are applied by depressing the
pedal which, in turns, applies pressure to the shoe and drum at each
wheel to stop the truck and illuminate the service or blackout
lights, according to the position of the VEHICLE LIGHTS switch.
Releasing the spring loaded pedal, in turn, releases the service
brakes.
The brake system is power assisted for reduced brake pedal
effort when the engine is running.
(b) The parking brake lever is located at the right side of the
operator's seat and connected to the transmission output shaft.
Pulling the lever up applies brake pressure at the output shaft of
the transmission which, in turn, prevents the axles and wheels from
rotating. Pushing the lever down releases the parking brake.
