Tightening torque procedure

1. Position the timing belt take-up device so that stud “a” is as shown in the figure. Then torque the two fastening nuts locking them slightly.
2. Insert a template 10 mm from tension lever “b”. Then turn it anti-clockwise so to advance hand “c” by 2 - 3 mm until they meet. Then fasten the two belt take-up device nuts without locking them.

• Turn the crankshaft clockwise by two turns to take cylinder 1 piston to DTC.
• Check whether hand “c” meets central notch “d” and torque the two belt take-up fastening nuts as prescribed.
• Remove the belt take-up tension lever “b”.

1. Turn the crankshaft to take cylinder 1 piston to TDC firing stroke with tool no. 1.825.013.000 (C.6.0183) and gauge.
2. Check alignment of the notches on the camshafts and those on the respective caps.

Tightening torque procedure

• Torque the cylinder head fastening screws as follows. The tighten torque order for each stroke is given in the figure.

1. Furthermore, check alignment of the notch on the phonic wheel with the reference pin on the front crankcase cover.
