Crankshaft fitting
NOTE
ACCORDING TO THE TYPE OF CRANKSHAFT, ITS INSTALLATION WILL FOLLOW TWO DIF-
FERENT PROCEDURES ("OPTION 1" AND "OPTION 2").
OPTION 1
Crankshaft with removable gear.
If the two timing chain control sprockets (1 - 2) on
the crankshaft were removed, check their exact
positioning carefully because the two components
cannot be interchanged.
Remember that the thicker sprocket (1) must be
positioned from the clutch side of the crankshaft.
