[8.21±0.04 in.]) control link A-2.

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.
