Oil period can be extended to 200 hours when CD type oil is used.
Normal change interval when fuel sulphur is 0.4% or less.
When sulphur content is 0.4% to 1.0% reduce oil change interval one-half.
When sulphur content is above 1% reduce oil change to one-fourth the normal interval.
Regardless of hours, change oil and filters every six months.
More often in dusty conditions. If after servicing the air cleaner, the exhaust smoke and/or loss of power
continues, discard that element and install a new element at least once a year.
Check valve lash after the first 80-100 hours of operation and then at least every 6 months regardless of
Use only distillate fuels (ASTM No. 1 or No. 2 Fuel Oil, or No. 1 D or No. 20 Diesel Fuel Oil are
examples) with a minimum cetane number of 40. Heavier oil is generally preferable because of its
higher energy content.
Use oils which meet Engine Service Classification CD, or MIL-L-2104C, in Caterpillar diesel engine
Use oils which meet Engine Service Classification CC, MIL-L-2104B or MIL-L-46152 in these Diesel
Use Multipurpose-type Grease which contains both 3 to 5% molybdenum disulfide conforming to MIL-L-
7866, and a suitable corrosion inhibitor. NLGI No. 2 Grade is suitable for most temperatures NLGI No. 1
or No. 0 are suitable for extremely low temperatures.
Use either distilled water; or, odorless, tasteless drinking water. Do not use mineral water, water con-
taining iron, salt water or softened water.
Use clean water that is low in scale forming minerals not softened water. When the temperature is below
32°F (0°C), a sufficient amount of permanent type anti-freeze must be added to adequately protect your
engine against freezing. Adding Caterpillar Coolant System Conditioner is recommended if protection is
for temperatures above -20°F (-29°C).
