GENERAL

Recommended preventive
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 the recommended intervals is most
important.
Lubrication requirements are referenced to the lube
key found in the Lubrication Chart (page 40-4). For
detailed service requirements
components, refer to the shop manual section for
that component (for example, Section H for
suspensions, Section L for hydraulic system, etc).
Refer to the manufacturer's service manual when
servicing any components of the General Electric
propulsion 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
place 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 should be 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
delivered to each serviced point. The lubrication
injectors can be adjusted to vary the amount of
lubricant delivered. In addition, the timer for
lubrication intervals is normally adjustable. For
adjustments to these devices, refer to Section 42,
Automatic Lubrication System.

HYDRAULIC TANK SERVICE

There are two sight gauges (1, Figure 40-1) on the
side of the hydraulic tank. With the engine stopped,
key switch OFF, hydraulic system depressurized, and
body down, the oil level should be visible in the
center of the top sight gauge. If the oil level is not
visible in the center of the top sight gauge, follow the
instructions below for adding oil.

Adding Oil

NOTE: 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.
1. Make sure that the engine is stopped, key
switch is OFF,
depressurized, and body is down
2. Remove fill cap (2) and add hydraulic oil until
the oil level is visible in the center of the top
sight gauge.
3. Install the fill cap.
4. Start the engine. Raise and lower the dump
body three times.
5. Check the hydraulic oil level again with the
engine stopped, key switch OFF, hydraulic
system depressurized, and body down.
6. Repeat Steps 1 - 5 until the oil level is
maintained in the center of the top sight gauge.
