(1) Install the fixed-length (304±1.0 mm [12±0.04 in.])
control link A-1 in between the fuel injection pump
control rack and the control lever on the right bank.

(2) Adjust the variable-length control link B-1 on the left
bank to 95.5 mm [3.76 in.], and tentatively tighten it.
Then fix it to the fixed-length (208.5±1.0 mm
[8.21±0.04 in.]) control link A-2.
(3) Assemble the variable-length control link B-1 into the
stop lever having a serrated hole. Install the fixed-
length (208.5±1.0 mm [8.21±0.04 in.]) control link A-2
to the fuel injection pump control rack.
Check that the fuel injection pump racks of both banks
are at the no-injection position, then install the stop
lever together with the spacer and cancel spring to the
serration on the control shaft.
Note: Adjust the engagement lengths even on right and left-
handed threads.
(4) Fine adjust the variable-length control link B-1 for the
left bank so that movement of the fuel injection pump
rack becomes the same on both banks.

If the play of fuel injection pump rack is in excess, fuel can not be stopped even when the governor brings the link to
engine stop position, and engine over-running may results.
