NOTICE
Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, testing,
adjusting and repair of the product. Be prepared to collect
the fluid with suitable containers before opening any
compartment or disassembling any component
containing fluids.
Refer to Special Publication, NENG2500, "Caterpillar
Dealer Service Tool Catalog" for tools and supplies
suitable to collect and contain fluids on Caterpillar
products.
Dispose of all fluids according to local regulations and
mandates.
Note: Change the engine oil and the filter after every
500 hours. This is the normal interval provided that the
following conditions are met:
• Only genuine Caterpillar filters must be used.
• Only Caterpillar Multigrade Diesel Engine Oil (DEO)
to specification CG-4 or an equivalent must be used.
Refer to Operation and Maintenance Manual,
"Lubricant Viscosities" and the appropriate Service
Manual for more detailed
lubricant information.
• Working conditions must be clean and applications
must be light. Obtain an SOS oil sample at the first
250 hours in order to determine if the oil change
interval can be decreased.
• The sulfur content of the fuel must be between
0.05% to 0.5%. If a higher percentage of sulfur is
present in the fuel, the engine oil and the filter will
need to be changed more often. 0.5% to 1.0% of
sulfur content will require the engine oil and the filter
to be changed after every 250 hours. 1.0% to 1.5%
of sulfur content will require the engine oil and the
filter to be changed after every 125 hours.
