Locate the flywheel in position so that the marking (a cut-out)
near the rim is against the No 4 cylinder crankpin axis. While
holding the flywheel stationary with tool Ä.60330/R, bolt it to the
crankshaft flange to the specified torque.
Using a ring compressor (tool 67.8125.9502), fit the pistons
and connecting rods to the cylinders (Fig.2-17).
WARNING. The hole for gudgeon pin in the piston is 1.2
mm set off, so the arrows on the piston crown must face the
timing belt end of the engine when inserting the pistons into
the cylinders.
Press the big-end bearing shells into the connecting rods and
caps. Guide the conrods and big-end caps onto the crankshaft
journal, then tighten the connecting rod bolts. The big-end caps
must be positioned so that the cylinder number on the cap is
against the cylinder number on the connecting rod big-end.
Refit the crankshaft sprocket. Locate the oil pump shaft and
secure it with the thrust flange.
Insert two centering pins into the cylinder block (Fig.2-17) and
locate the cylinder head gasket over them.
WARNING. Always fit the new cylinder head gasket.
Never re-use the old gasket.
Before refitting the gasket, remove any oil from the mat-
ing surfaces of the block and cylinder head. Make sure the
gasket is perfectly clean and dry. Avoid any incidental oiling
of the gasket.
Turn the crankshaft so that the pistons are midway in the
cylinder bore.
Refit the cylinder head complete with the valves, exhaust
manifold and intake pipe over the centering pins.

Tighten the cylinder head bolts in the established procedure
(Fig.2-18) in four steps to ensure a reliable fit and exclude further
tightening during vehicle servicing.
1st step - tighten the bolts 1-10 to 20 N•m(2 kgf•m);
2nd step - tighten the bolts 1-10 to 69.4-85.7 N•m
(7.1-8.7 kgf•m), while the bolt 11 to 31.36 -
39.1 N•m (3.2-3.99 kgf•m);
3rd step - turn the bolts 1-10 to 90°;
4th step - turn again all bolts 1-10 to further 90°.
WARNING. The cylinder head bolts can be re-used only
when their length is not in excess of 120 mm, otherwise
renew the bolt.
Before reassembly, immerse the bolts, thread and head,
into engine oil. Allow the excess oil drip for at least 30 min-
utes. Remove all entrapped oil from the bolt bores in the
cylinder head.
