0000001501 ANEROID COMPENSATOR

ACS adjustment Full load injection quantity at high altitudes and ACS adjusting method 1. Full load injection quantity adjustment (1)Remove the ACS cover and remove the bellows and adjusting shim. (2)Perform all adjustments as per the adjustment standard except for ACS adjustment. 2. ACS adjustment (1)Assemble the ACS cover, bellows and adjusting shim. (2)At N = N1, adjust using shims so that the decrease amount for altitude is as specified in the graph.

0000001801 POTENTIOMETER ADJUSTMENT

Adjustment of the potentiometer At pump speed N1 and oil temperature t, and at lever angle a (L1) from idle, adjust the potentiometer so that the specifications are satisfied. Standard value : V+-0.03=0.187Q+1.593 Q = injection quantity
----------
N1=700r/min t=48~52degC a=14deg L1=8.9mm

0000001901 W-CSD ADJUSTMENT

Adjustment of the W-CSD 1. Adjustment of the advance angle of the timer (1)Determine the timer advance angle using the graph. Graph TA-t: -10<= t(deg C) <= 20 TA = -0.0284t+1.367 20 <= t (deg C) <= 60: TA = -0.02 t + 1.2 Graph L-t: 10 <= t (deg C) <= 20 L = -0.0667t+3.23 20 <= t (deg C) <= 60: L = -0.05 t + 2.9 (2)(1) Adjust with the screw (A) so that the timer advance angle determined in the item (1) is obtained. 2. Setting the intermediate lever position (1)Insert a block gauge L1 between the idling set screw (G) and the control lever (F). (2)Align the intermediate lever (D) with the aligning line (I) and position it perpendicularly. Fix screw (E) so that it contacts the control lever (F). 3. W-CSD lever adjustment (1)Insert a block gauge L2 determined from the graph L - t in 1. (1) between the idle set screw (G) and the control lever (F). (2)Fix screw (B) so that the W-CSD lever (C)'s roller contacts the intermediate lever (D). Note: The temperature of the wax at adjustment must not exceed a. When inserting the block gauge, separate lever (C) and (D) using screw (B) to prevent excessive force on the lever.
