3.7 Adjustment of crank angle offset in WECS
After the mechanical work on the CAS and CAS drive, the crank angle offsets must
be adjusted.
⇒ Turn the engine with the turning gear until the flywheel marks show T.D.C. of
Cyl. No.1 = 0.0
_ .
⇒ Marks ’MK’ must be aligned as indicated in Fig. ’J’.
⇒ T.D.C. of the Cyl. No.1 can be cross checked from the crankcase. But safety
measures must be taken accordingly before opening of the crankcase, see
’Warning labels’ located near the crankcase doors on the engine.
⇒ Start the ’flexView’ programme and go to the ADJUST card.
⇒ With the flywheel position as described above, read the crank angle values
displayed in the fields ’Crank angle 1/2’. If they are different from
0.0 _ CA,
enter the displayed values as offset in the fields ’CA 1/2 Offs’.
Remark! For negative deviations, e.g. 359.8 < _ , use negative values − 0.2 < _ .
