Test data Ex:

0000001801 W-CSD ADJUSTMENT

Adjustment of the W-CSD 1. Set the intermediate lever position. Insert a block gauge L1 determined from the graph between the idling set bolt H and the bracket I. Align the intermediate lever E with the aligning mark and position it perpendicularly, then fix it so that the control lever G contacts the screw F. 2. Timer advance adjustment Adjust using screw (A) so that the timer lift is the value determined from the graph. 3. W-CSD lever adjustment Insert a block gauge L2 determined from the graph between the idling set bolt (H) and the bracket (I). Adjust the screw (D) so that the W-CSD lever (C)'s roller contacts the intermediate lever (E). Then fix the screw. Note: The temperature of the wax at adjustment must not exceed a. When inserting the block gauge, separate (C) and (E) using screw (D) without using excessive force on the lever. A = after adjustment, turn clockwise 2 turns. X = temperature t (deg C) Y1 = timer stroke TA (mm) Y2 = control lever dimension L mm (control lever position

0000001901 DASHPOT ADJUSTMENT

Adjustment of the dash pot 1. Insert a block gauge L (thickness gauge) between the idle set screw and the bracket. 2. In the above condition, adjust the locknut so that the dashpot adjusting screw (A) contacts the pushrod, and then fix it using the locknut (B). Note: (1) The dashpot and control lever contact faces must be smooth. (2)Confirm that the control lever returns to the idling position.

Information:

Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
The following changes are adaptable to the products within the listed serial numbers, and are effective with all products after the listed serial numbers.The new and former parts and listed in Table 1.

(1) The 536-5400 Plates are used to rework the 536-3638 Catalytic Converter Gp (Left-Hand) and the 536-3639 Catalytic Converter Gp (Right-Hand).
(2) The new 549-2046 Clean Emissions Module Ar is universal and can be installed on both sides of the engine.Inspect the 536-3638 Catalytic Converter Gp (Left-Hand) and the 536-3639 Catalytic Converter Gp (Right-Hand) for cracks before replacing the DOCs. If no cracks are present during inspection, the two 536-5400 Plates can be welded to the top of each DOC for support. Refer to special instruction for the complete list of parts and rework instructions.Note: If the 536-3638 Catalytic Converter Gp (Left-Hand) and the 536-3639 Catalytic Converter Gp (Right-Hand) are reworked, install the DOCs back into the original position. The DOCs are not interchangeable.The special instruction is available through the normal literature distribution system. The publication can also be found on the Caterpillar Service Information System (SIS).
