The position of the
conrod on the crank-
shaft must be as
shown in Table A,
which lists the screw
tightening torque
values.

If necessary, tighten the nuts with a calibrated dynamometric
wrench, adjust conrod-crankshaft coupling with light hammer
blows. After that, tighten the nuts again with the dynamometric
wrench; the conrod must be able to rotate freely (see Table A).
Fit the conrods onto the crankshaft after placing the latter into its crankcase (see section 1 page 3); once
you have completed the tightening process, screw theoil spash pins into their housing and fasten them
with a special adhesive.
