Fuel system
Note: A change of shim size by 0.1 mm (.0039 in)
implies that the injection start is moved approx. 1 °.
An increase in shim size reduces the injection
angle and conversely a decrease in shim size in-
creases the angle.
Shims are available in the following sizes: 0.2, 0.3,
0.4
and 0.5 mm (.0078, .0118, .0157 and .0196 in).
NOTE! In the event that no shims are required,
liquid sealing compound should be used.
Replace the pressure valve. Screw in the pressure
valve holder by hand. If the pressure valve holder
will not go in, screw the holder backwards and for-
wards quickly 1/4-1/2 turn until the pressure valve
goes in the pressure valve holder. Screw down the
pressure valve fully by hand until the 0-ring begins
to be pressed together. Tighten after this with a
17
mm spanner.
Tightening torque, see Technical data.
Q
WARNING! The pressure valve holder must be
screwed in by hand so that it is possible to feel
that the pressure valve goes correctly into the
valve holder. Never use force to screw the valve
holder down since this can damage the pressure
valve. If the pressure valve cannot be turned in
the valve holder the pump must be dismantled
and the same method applied with the pump in a

Adjustment of the injection angle can also be made
by measuring the piston height with a dial gauge.
