To check the valves clearance, it is necessary to have access to the cylinder head covers and then remove the components listed below.
Unscrew the two fixing screws (1) of the cover (2) according to the crankshaft.
Fit the tool handgrip 88713.0123 In the holes of the generator cover to be able to turn the crankshaft so that the valve on which the control is carried out is in rest position.
With the valve in the rest position, slide a feeler gauge between rocker arm (a) and the lowest side of the cam (b) to measure the clearance.
The clearances must be within the specified limits:
With the valve in the rest position, slide a feeler gauge between closing
rocker arm (c) and the highest side of the cam
(d) to measure the clearance.
If detected values exceed the specified limits, replace opening and/or closing shims, as described in paragraph "removing the valves" (sect. 9 - 4.5), With an adequate height to obtain the specified clearance.
Note
Opening rocker arm shims measuring from 1.8 To 3.45 Mm and closing rocker arm shims measuring from 2.2 To 4.5 Are available as spare parts. The size is punched on the shim.
Remove the handgrip tool 88713.0123 From the hole of the generator cover.
Make sure that the o-ring (3) is fitted on the cover (2).
Refit the external cap (2) by tightening the two retaining screws (1) to a torque of 10 nm (min. 9 Nm - max. 11 Nm) (sect. 3 - 3, Engine torque settings).
Change timing belts
To replace the timing system belts follow the procedures described in paragraph "removal of the movable tensioner/timing belt" and "refitting the timing belts" (sect. 9 - 4.2).
Passive key
Introduction
The passive key (1) is used when the active key is not working correctly or
is not available.
The passive key works as a transponder, and must therefore be placed physically
onto the antenna to work.
The mechanical part (2) of the key is used to open the seat or the tank plug ...
Reassembly of the control unit
Insert the control unit (4) into the protecting sheath (5) and position it on
the airbox.
Position the relay supporting bracket (2) by starting and tightening the
screws (1) to a torque of 6 nm +/- 10% (sect. 3 -
3, Frame torque settings), and connect the control unit connectors (3).
