Fitting the piston and the cylinder

– Fit a new cylinder base gasket.
– Oil the piston pin bearing in the connecting rod and the piston

pin itself.

– Fit the piston and fasten the piston pin with two new retaining

rings.

NOTE:

THE ARROW ON THE PISTON TOP MUST POINT IN

THE DIRECTION OF TRAVEL.

- Oil the piston and fit the piston rings.

The scraper ring gap should face the back of the vehicle.

The compression ring gap should form an angle of 90° with the
scraper ring gap.

– Pull up the timing chain through the chain tunnel.

– Push the cylinder onto the piston and remove the mounting

ring.

WHEN FITTING THE CYLINDER, TAKE CARE NOT TO
BREAK THE OIL SCRAPER RING!

Fitting the cylinder head

– Check that the two centring bushes are properly seated in the

cylinder.

– Fit a new cylinder gasket (with the inscription “ALTO” facing

upwards) and fit the cylinder head and the timing chain.

– Oil the threads and the contact surfaces of the four flange

screws and fit them along with the related washers.

– Tighten the flange screws in three steps following a crosswise

pattern:

1st step – tighten until a slight resistance is felt.
2nd step – tighten to 40 N·m.
3rd step – tighten to 50 N·m.

– Fit and tighten the three screws 1 (M6x45) and 2 (M6x40) to

10 N·m.

Screw 2 must be fitted laterally on the timing chain guard
with a new copper retaining ring (6x10x1).
