Fit the exhaust valve motor cable (m) inserting the end fitting (f) in the suitable hole of pulley (g).
Note
The exhaust valve motor cable (m) must be positioned above the wiring (h) of the exhaust valve motor (34).
Insert the cylindrical terminal (l) into the suitable seat of the exhaust valve motor (34) and make sure to bring it fully home.
Note
If it proves difficult to insert the terminal (l) fully home into its seat, apply lubricant for rubber to the terminal.
Tie the wiring (h) using a large self-locking tie wrap (n) in the area of the cover (32) shown.
If previously removed, place the exhaust valve motor assembly (32) on the right plate of the rear subframe, start the screws (29) with washers (30) and tighten them to a torque of 10 nm +/- 10 % (sect. 3 - 3, Frame torque settings).
Position the control cable (25) in the plate (c).
Insert the end fitting (b) on the exhaust valve (d) and block it with the circlip (39).
Warning
Make sure the end fittings (b) at cable ends are properly fitted onto the pulleys of the exhaust valve and of its motor.
Check that the cylindrical terminal (l) is fully inserted (fully home) into the suitable seat of the exhaust valve motor.
After assembly, the cable (25) on exhaust valve and exhaust valve motor is adjusted automatically by dashboard software, that causes the valve to open fully at the first key-on, and then goes back to rest position with the valve fully closed.
Refit the exhaust by-pass valve cover (27) by starting and tightening the screws (28) to a torque of 8 nm +/- 10% (sect. 3 - 3, Frame torque settings), starting with the front one.
Refit the silencer, as described in the paragraph "refitting the silencer" of this section.
If removed, fit the copper washers (18) to the plugs (17), start the plugs into the vertical (22) and horizontal (24) head exhaust manifolds and tighten them to the torque of 25 nm +/- 10% (sect. 3 - 3, Frame torque settings).
If the silencer heat guard had been removed, check the presence of clips (43) on the silencer (4).
Important
Assembly operations described below must be performed following sequence x - y - z.
Fit the washers (12) on the screws (40).
Insert the screws (40) in the holes of the heat guard (41).
Insert the other three washers (12) and the spacers with collar (42) on the protruding ends of the screws (40).
note
The spacers (42) must be oriented with the collar (j) facing the heat guard (41) as shown.
Fit the heat guard (41) by starting the screws (40).
Tighten the screws (40) to a torque of 5 nm +/- 10% (sect. 3 - 3, Frame torque settings), following sequence z - x - y and making sure the washers (12) are centred to the collars (j) of the spacers (42).
Check the presence of the rubber pad (46) on the heat guard (45).
Fit the washers (12) on the screws (44) using the recommended threadlocker.
Insert the screws (44) in the holes of the rear heat guard (45).
