6 Carefully push the piston through the piston ring compressor and check that the connecting rod is onto the
crank pin.
7 Rotate the crankshaft counter-clockwise, when seen from the front, until the crank pin is at its lowest
position. At the same time carefully apply pressure to the top of the piston with a suitable piece of wood or
plastic. This will keep the big end in contact with the crank pin.
Note: The crankshaft is rotated counter-clockwise to ensure that the shell bearing in the big end remains in
position.
8 Clean the connecting rod cap and the lower half of the shell bearings. Fit the bearing to the cap; ensure that
the location tag is fitted correctly in its recess (C1). Lubricate the bearing with clean engine lubricating oil.
9 Fit the cap and ensure that the assembly number is the same as that on the connecting rod and that the
numbers (D) are on the same side. Fit the nuts finger tight; ensure that the flat side of the head of the bolts is
towards the connecting rod. Tighten the nuts gradually and evenly to the recommended torque of 77 Nm
(57 lbf ft) 7,9 kgf.
