Read dial indicator for proper lift (see Calibration
Chart for specification). Zero the pump stand
degree wheel at this point for phasing. Return
tappet to B.D.C. and repeat Steps 6 and 7 to
Compensate for deviation from the specified
measurement by inserting the proper size
adjusting spacer (available in thickness steps of
0.05 mm) between the barrel flange and pump
housing (Figure 4).
ADJUSTING SPACERS OF THE SAME
THICKNESS MUST BE USED ON
BOTH SIDES OF BARREL AND VALVE
ASSEMBLY AND ONLY ONE SPACER
SHOULD BE USED ON EACH SIDE.
Figure 4. Inserting Adjusting Spacers
Check port closure for the remaining plungers in
pump discharge order by rotating the camshaft
in 60 degree intervals.
At each of these intervals check port closure as
outlined in Steps 7 and 8 (nozzle bleeder screw
opening to correspond with element number).
If port closure is not exactly as specified 1/2
degree, adjust by selecting proper spacer for
under the barrel flange. If port closure occurs
too early, increase spacer thickness. If too late,
reduce spacer thickness.0.05 mm spacer

Step 2. Adjust shut-off lever stop screw (Figure
5) to 1.5 - 2.0 mm (.060 - .079") rack position.
