10. Align the cylinder liner alignment mark with the
corresponding mark on the front edge of the
crankcase.
Note:
• Ensure that the piston/liner/connecting rod
assemblies align correctly with the crankpins
during assembly into the crankcase.
Always renew the big end bolts and nuts. The bolts are
torqued near to their yield point when first installed and
are severely weakened if re-used. Re-using the original
bolts may cause bolt breakage resulting in engine
damage, loss of motorcycle control and an accident.
11. Align the connecting rod to the crankshaft and fit the
big end cap. Tighten the NEW cap nuts as follows:
The torque characteristics of the connecting rod bolts
are sensitive to the rate at which they are tightened. If all
the torque is applied in one action, the bolts will be
stretched beyond their yield point. This may cause bolt
breakage resulting in engine damage, loss of motorcycle
control and an accident.
Lubricate the under-head and thread areas of the bolts
with undiluted molybdenum disulphide grease. Tighten
the bolts, in two stages as follows:-
a) Tighten to 14 Nm.
b) Tighten through 120
