Fuel system
Adjustment of injection angle
Use a scrapped fuel pipe. The pipe makes it easier
to see when the fuel begins and stops flowing out
from the valve.
Fit the injection pump as per the previous section with
the exception of item 1 which is changed to item 1 be-
low.
1.
Place a shim 0.5 mm (.0196 in) in thickness under
the injection pump flange.

Remove the front pressure valve holder from the
injection pump.
5.
Continue turning the crankshaft slowly clockwise
until the fuel stops flowing out from the pressure
valve holder. Check the position of the crankshaft
to the marking on the pulley and engine block at
this point. See Fig. 90.
If the position is after "Y°" (B.T.D.C.) a thinner
shims should be used under the injection pump
flange. If the position exceeds "Z°" (B.T.D.C.) a
thicker shims should be fitted instead. (See table
below).
