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 pump speed N1, adjust using a shim to obtain the decrease for the altitude shown in the table.
X1 = atmospheric pressure
X2 = altitude
Y = decrease quantity
(A) = adjustment value
(B) = test value

Timer adjustment
Assemble the timer's measuring device on the low pressure side and measure timer advance.
Select one of the 6 timer springs. It is necessary to install at least 1 shim (0.6 mm) on either side.
Maximum is L1 mm on piston side and L2 mm on cover side. Do not exceed.
Use pipe corresponding to 146606-3920.
