The LUBRICATION AND MAINTENANCE CHART lists all serviceable items which are either standard equipment or attachments commonly ordered on your model of engine.
Items needing periodic maintenance are grouped according to frequency of service. Items needing service as required are grouped according to the general system of which they are a part, and follow the periodic interval items.
The page letter and number in the right hand column of the chart is the reference page for the detailed instructions in the LUBRICATION AND MAINTENANCE PROCEDURES. These procedures are grouped according to the various engine systems, e.g., the Diesel Engine Lubrication System is A, the Air Induction and Exhaust System is B, etc.
The number following the letter indicates the page number within that system, e.g., B-2 is the second page in the Air Induction and Exhaust System.
Items which do not pertain to your engine may be lined out to customize your charts.

The service meter is the most reliable method of determining service intervals. If your engine does not have a service meter, use the following figures. These figures are based on a 10 hour day and a 2000 hour year. If your operation differs from these limits, base your service intervals on actual running time. Keep an accurate record of operating time.
Do not use these figures as an optional service interval for engines with service meters.
10 hours - One day
50 hours - One week
100 hours - Two weeks
200 hours - One month
Note 1. 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.
Note 2. 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.
Note 3. Check valve lash after the first 80-100 hours of operation and then at least every 6 months regardless of service hours.
Key To Lubricants And Fuels
CD - Use oils which meet Engine Service Classification CD, or MIL-L-2104C, in Caterpillar diesel engine crankcases and gear compartments.
CC - Use oils which meet Engine Service Classification CC, MIL-L-2104B or MIL-L-46152 in Caterpillar 3100 Diesel Engine crankcases and/or gear compartments.
MPGM - Use Multipurpose-type Grease which contains both 3 to 5% molybdenum disulfide conforming to MIL-M-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.
Fuel - Use only distillate fuels (ASTM No. 1 or No. 2 Fuel Oil, or No. 1D or No. 2D Diesel Fuel Oil for examples) with a minimum cetane number of 40. Heavier oil is generally preferable because of its higher energy content.
