Place the stem in a vice, closing the teeth of the vice on the two flat areas, and proceed with setting, using a
torque wrench (pos. 1, fig. 50) as shown in section 3, “Screw tightening settings”.
Insert the connecting rod into the piston head (pos. 1, fig. 45) and then insert the pin (pos. 1, fig. 44). Apply
the two shoulder Seeger rings using the correct tool (pos. 1, fig. 43).
The assembly is correct if the small end, piston head and pin rotate freely.
Separate the small ends from the big end halves. Correct pairing is ensured by the numbering on one side
(pos. 1, fig. 42). After verifying that the casing is perfectly clean, insert the big end half/piston head
assembly into the cylinder tube in the casing (pos. 1, fig. 41).
The big end half/piston head assembly must be inserted into the housing with the
numbering of the big end halves visible from above.
Lock the three assemblies using the special device (p/n F27566200) (pos. 1, fig. 40). Lock the crankshaft
through the rear opening of the casing and lay it on the bottom.
Connect the stem to the piston head. Insert the Ø 5 roll pin in the hole on the piston head (pos. 1, fig. 48) and
connect the stem to the piston head using a M10x35 screw (pos. 1, fig 49).
