Hydraulic Tank Service; Adding Oil; 930E Service Capacities - Komatsu 930E-2 Shop Manual

Preventive Maintenance will contribute to the long life
and dependability of the truck and its components. The
use of proper lubricants and the performance of
checks and adjustments at recommended intervals is
most important.
Lubrication requirements are referenced to the lube
key found in the Truck Lubrication Specifications Chart
(page P2-2). For detailed service requirements for
specific components, refer to the SERVICE MANUAL
section for that component (i.e. Section "H" for Sus-
pensions, Section "L" for Hydraulic System, etc.).
Refer to manufacturer's service manual when servic-
ing any components of the General Electric System.
Refer to engine manufacturer's service manual when
servicing the engine or any of its components.
The service intervals presented here are in hours of
operation. These intervals are recommended in lieu
of an oil analysis program which may determine
different intervals. However, if the truck is being
operated under extreme conditions, some or all, of the
intervals may need to be shortened and the service
performed more frequently.
The 930E Truck is equipped with a Lincoln Automatic
Lubrication System. The initial setup for this system
provides for nominal amounts of lubricant to be deliv-
ered to each serviced point. The lubrication injectors
can be adjusted to vary the amount of lubricant deliv-
ered. In addition, the timer for lubrication intervals is
normally adjustable. For adjustments to these devices,
consult the "Lincoln Automatic Lubrication System" in
this section.

LUBRICATION AND SERVICE

HYDRAULIC TANK SERVICE

There are two sight gauges on the side of the hydraulic
tank. With engine stopped, keyswitch "off", hydraulic
system bled down and body down, oil should be visible
in the top sight gauge. If hydraulic oil is not visible in
the top sight gauge, add oil as follows:

Adding Oil

Keep the system open to the atmosphere only as long
as absolutely necessary to lessen chances of system
contamination.
Service the tank with clean Type C-4 hydraulic oil only.
All oil being put into the hydraulic tank should be
filtered through 3 micron filters.
