Milton CAT 321 D LCR - Manual (Page 13)

Ground Level Service. The design and
layout of the 321D LCR was made
with the service technician in mind.
Many service locations are easily
accessible at ground level allowing
critical maintenance to get done quickly
and efficiently.
Air Filter/Radiator Compartment.
The left rear service door allows easy
access to the engine radiator, oil cooler
and air-to-air-aftercooler.
A wire mesh screen is provided between
the aftercooler and radiator/oil cooler,
where these is enough clearance to blow
off debris using a wand. The air filter,
also located within this compartment,
features a double-element construction
for superior cleaning efficiency.
When the air cleaner plugs, a warning
is displayed on the monitor screen
inside the cab.
Access to the washer tank and
maintenance points for the electric
components, such as the battery, circuit
breaker and controller are also located
in this compartment. The jump-start
receptacle, which is an attachment for
the cold weather package, is located
near the battery.
Pump Compartment. A service door on
the right side allows for ground level
access to the hydraulic pump, case drain
and pilot filters.
Greasing Points. A concentrated remote
greasing block on the boom delivers
grease to hard-to-reach locations on
the front.
Anti-Skid Plate. Anti-skid plate covers
top of storage box and upper structure
to prevent slipping during maintenance.
Diagnostics and Monitoring.
The 321D LCR is equipped with S•O•S
SM
sampling ports and hydraulic test ports
for the hydraulic system, engine oil,
and for coolant. A test connection for
the Cat Electronic Technician (Cat ET)
service tool is located in the cab.
Extended Service Interval. 321D LCR
service and maintenance intervals
have been extended to reduce machine
service time and increase machine
availability.
