2. Inspection and adjustment
87
Part code of C.S.D. cancel spacer:
129671-51990.
1. Never turn the screw driver or steel bar to
the right for W-C.S.D. release. The C.S.D.
lever or wax pellet will be damaged.
2. The work under the W-C.S.D. canceled
should be done for less than 1 hour. If a wax
is no-loaded (canceled) for 1 hour or more,
the wax pellet may be damaged and
stabilizing treatment must be performed for
the wax pellet to recover.
3) Turn the crankshaft slowly 20-30 degrees
before the compression top dead center of
No.4 cylinder (gear case side), and find the
point (crankshaft angle) that the plunger lift is
0. Set the dial gage to 0 at the minimum value
of the plunger lift. Check the minimum value is
set to 0 by turning the crankshaft right and
left.
4) Turn the crankshaft slowly to the engine
rotating direction (counterclockwise viewed
from stern) and set the crankshaft to the
compression top dead center.
5) Check the dial gage. If the plunger lift comes
off the standard value, loosen the 5 nuts
about 90 degrees, which fix the VE pump
bracket to a gear case flange.
The standard value of plunger lift (when the
W-C.S.D. is released)
6) Turn the pump for injection timing adjustment
and adjust the plunger lift to the standard
value.
After the adjustment of the injection timing,
tighten the 5 nuts and fix the VE pump
bracket.
7) Remove the spacer and the screw driver or
steel bar.
