Clean, lubricate and install the lower bearing shell in
the cap. Ensure that the guide lug is slid well into
the cut out (A2). Remove the protective hosing from
the connecting rod screws and check that the
screws have not been damaged. Install the con-
necting rod cap. Ensure that the unit number on the
cap is the same as on the connecting rod (B) and
that both unit numbers are turned in the same direc-
tion.
11
Install new nuts for the connecting rod screws.
Tighten them evenly and in stages to 47 Nm.
12
Check that the crankshaft can be freely turned.

Piston and connecting rod as-
sembly, replacement (13A-03)
1
Drain the engine oil and the engine coolant system.
2
Remove the cylinder head assembly, operations
12A-07.
3
Turn the crankshaft until the pistons are at the
same height in the cylinder bores. Place a suitable
clean rag over the piston to fill the cylinder bores.
Remove all soot from the upper section of the cylin-
der bore with a coarse emery cloth. The emery
cloth should be dampened with oil in order to retain
the impurities. Polish the cleaned surface with a
fine emery cloth. Clean the cylinder bore and re-
move the rag.
4
Remove the oil pan, operation 18A-03.
5
Remove the oil screen and extractor pipe if re-
quired, operation 18A-04.
6
Check that all the connecting rods and the caps are
marked with the correct cylinder number (A). If they
are not marked, mark them from 1 to 4 with the
number 1 at the timing belt cover end.
Big ends, inspection (13A-02)
Check the bearing shells and the big end journals
for wear and other damage.
