0000001801 M-CSD ADJUSTMENT
M-CSD adjustment
1. Fixing the M-CSD
(1)At roller holder advance angle a adjust the lever shaft ball pin so that it contacts the roller holder.
(2)At this time, adjust the position of the M-CSD lever (A) using adjusting screw (C) so that the clearance between the M-CSD lever (A) and the stopper (B) becomes L1. Then fix using nut (D).
TT
2. M-FICD adjustment
(1)Move the CSD lever (A) through its full stroke.
(2)Adjust screw (E) so that the control lever (G)'s position is b (the clearance between the control lever and the idling set screw is L2). Then fix using the nut (F).

Fuel System Information
Check the fuel level in the tank daily by observing the sight gauge, if equipped.
Fill the fuel tank at the end of each day of operation to drive out moist air and to prevent condensation. Maintain a fairly constant level in the tank (near the top) to avoid drawing moisture into the tank as the level decreases. Do not fill the tank to the top. Fuel expands as it gets warm and may overflow.Drain water and sediment from tank at the interval specified in the Maintenance Schedule.Do not fill fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to fuel system parts.
Fuel Recommendations
Use only fuel as recommended in this section. The fuels recommended for use in Caterpillar engines are No.2-D diesel fuel and No.2 fuel oil, although No. 1 grades are acceptable. The following fuel specifications are some of the worldwide fuels which may meet the requirements. Caterpillar Diesel Engines are capable of burning a wide range of distillate fuels. The use of clean, stable blends of distillate fuel which meet the following requirements will provide quality engine service life. Sulfur
The percentage of sulfur in the fuel will affect the engine oil recommendations. Fuel sulfur is chemically changed during combustion to form both sulfurous and sulfuric acid. These acids chemically attack metal surfaces and cause corrosive wear.Certain additives used in lubricating oils contain alkaline compounds that are formulated to neutralize these acids. The measure of this reserve alkalinity in a lubricating oil is known as its Total Base Number (TBN). TBN values are essential to neutralize the acids from combustion gases and to minimize corrosive wear.Fuels containing 0.5% or less sulfur may be used with recommended crankcase oil drain intervals using API CF-4 performance oils. With sulfur above the 0.5% level, use API CF-4 performance oils with an ASTM D-2896 Total Base Number (TBN) of 10 times the fuel sulfur for normal oil drain intervals.Caterpillar recommends infrared analysis (in conjunction with wear metal analysis) of used oil in determining the effectiveness of oil TBN and acid neutralization. The Caterpillar dealer S O S program provides this information. Regular oil analysis (S O S) will provide information to monitor oil properties and engine wear metals to maintain successful engine protection and establish oil drain intervals.Periodically request fuel sulfur content information from your fuel supplier. Fuel sulfur content can change with each bulk delivery. ASTM D-2896 can normally be found at your local technological society, library or college. Any American Petroleum Institute (API) classification performance oil should have sufficient TBN for fuels with less than 0.5% sulfur. Fuels containing 0.5% or less sulfur may be used with recommended crankcase oil drain intervals using API CF-4 performance oils.Additives
Fuel additives are generally not recommended nor needed for the specified fuels listed. Cetane improvers can be used as necessary for the direct injection engine requirements. Biocides may be needed to eliminate microorganism growth in storage tanks. In cold conditions, treatment for entrained water may also
