Put ring compressor (A) in position on the cylin-

position in the same cylinder liner from which it
was removed and into the ring compressor. Make
sure the “V” mark on the piston is in alignment
with the “V” mark on the cylinder block.
Push the piston into place as the connecting rod is
put into position on the crankshaft.
Put clean engine oil on bearings, bolt threads
and surfaces of the nuts that make contact with
the connecting rod caps. Put caps (1) in posi-
tion on the connecting rods and install the nuts.
Tighten the nuts to a torque of 40 ± 4 N·m (30
± 3 lb.ft.). Put a mark on each nut and the end
of each bolt. Tighten the nuts 90° more.
CAUTION
When connecting rod caps are installed, make
sure the number on the side of the cap is next to
and respective with the number on the side of
the connecting rod.
