Grease Points Identification
Illustration 173 g0121 1917
Typical example
On machines that are equipped with the Open Roll
Over Protective Structure (OROPS), the identification
film is located in the engine compartment to the back
plate of the enclosure group. On machines that are
equipped with the Enclosed Roll Over Protective
Structure (EROPS), the identification film is located
on the inside of the lower door.
The identification film shows the lubrication points on
the machine that need to be serviced and the
maintenance intervals between each of the checks.
Note: Refer to Operation and Maintenance Manual,
"Maintenance Interval Schedule" for the
recommended intervals.
S O S Information
SOS Services is a highly recommended process for
Caterpillar customers to use in order to minimize
owning and operating cost. Customers provide oil
samples, coolant samples, and other machine
information. The dealer uses the data in order to
provide the customer with recommendations for
management of the equipment. In addition, SOS
Services can help determine the cause of an existing
product problem.
Refer to the appropriate Service Manual for detailed
information concerning SOS Services.
Refer to the Operation and Maintenance Manual,
"Maintenance Interval Schedule" for a specific
sampling location and a service hour maintenance
interval.
Consult your Caterpillar dealer for complete
information and assistance in establishing an SOS
program for your equipment.

Welding on Machines and Engines
with Electronic Controls
Proper welding procedures are necessary in order to
avoid damage to the electronic controls and to the
bearings. When possible, remove the component
that must be welded from the machine or the engine
and then weld the component. If you must weld near
an electronic control on the machine or the engine,
temporarily remove the electronic control in order to
prevent heat related damage. The following steps
should be followed in order to weld on a machine or
an engine with electronic controls.
1. Turn off the engine. Place the engine start switch
in the OFF position.
2. If equipped, turn the battery disconnect switch to
the OFF position. If there is no battery disconnect
switch, remove the negative battery cable at the
battery.
NOTICE
Do NOT use electrical components (ECM or ECM
sensors) or electronic component grounding points
for grounding the welder.
3. Clamp the ground cable from the welder to the
component that will be welded. Place the clamp
as close as possible to the weld. Make sure that
the electrical path from the ground cable to the
component does not go through any bearing. Use
this procedure in order to reduce the possibility of
damage to the following components:
• Bearings of the drive train
• Hydraulic components
• Electrical components
• Other components of the machine
4. Protect any wiring harnesses from the debris
which is created from welding. Protect any wiring
harnesses from the splatter which is created from
welding.
5. Use standard welding procedures in order to weld
the materials together.
