Determining the injection angle, shim thickness, and fitting of injection
pumps
NOTE! The injection angle and type of camshaft is stated on the engine identification plate.
To follow the procedure described below, is only required if the engine block, camshaft or a roller tappet has been
replaced.
When fitting existing injection pumps see section "Injection pump installation" in this chapter.
When changing an injection pump only, see chapter "Changing injection pump".
44. Fit the protractor (999 8679) to the flywheel flange
on the crankshaft.
NOTE! Make sure that you tighten the screws so that
there is no play.
45. Attach a pointer.
Use a magnetic stand.
46. Position the measuring bar (999 8678) with
spacers on the engine block over the piston be-
longing to the injection pump for which you are
setting the timing.
Turn the crankshaft in the direction of engine
rotation until the dial gauge has reached its
turning point. Set the dial gauge to "0".
IMPORTANT! The dial gauge must be placed in
the center of the gudgeon pin direction.
