Right-bank linkage - Overall view
(1) Set the length of the link A between the fuel injection
pump rack and the control link lever (for both right and
left banks) to 126.5±0.3 mm [4.98±0.012 in.], and
install the link A to the right and left banks respectively.
(2) Install the right-bank variable length control link B-1
(140.5±0.3 mm [5.53±0.012 in.]) between the control
link lever and control lever.
(3) Set the left-bank variable-length control link B-2 to
147 mm [5.79 in.], and fit the link to the stop lever hav-
ing a serration hole.
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.
Right and left-bank control links
(4) Fine adjust the left-bank variable-length control link C
so that both right and left-bank fuel injection pump
racks move the same distance.
