When turning camshaft, crankshaft should not be at TDC. Risk of piston valves / head fault.
t
Respect the toothed belt D.O.R. - risk of breaking.
–
Align camshaft sprocket mark with marking on cylinder head cover -arrows-.
Engine installed:
–
Set the crankshaft to the TDC for cylinder 1 -arrow-.
Engine removed:
–
Set the damper to the TDC for cylinder 1 -arrows-.
–
Carefully turn the eccentric with the rotation tool -T20197- clockwise, until the eccentric is almost at the limit -B-.
–
Place timing belt on crankshaft sprocket (observe direction of rotation).
–
Fit timing belt onto coolant pump, tensioning roller and camshaft sprocket.
–
Install tensioner for timing belt.
–
Turn the eccentric with the rotation tool -T20197- anticlockwise (eccentric projection moves to the limit -A-) until the counterhold -T10008- can be removed without tension.
–
Relax the counterforce of the tensioner clockwise (the eccentric projection moves to the limit -B- until reaching the dimension -a-.
Dimension specification -a-: 4 ±1 mm
Note
t
The dimension “a” reduces when tightening the tensioning roller securing bolt. Therefore, adjust generously with a drill of 4 mm of Ø.
t
With a hot engine, the dimension “a” may reduce to 1 mm.
–
Hold tensioning roller in this position and tighten to 20 Nm 45° (1/8 turn).
–
Install lower and centre timing belt guards.
Note
Place the bolts into the console support before positioning it.
–
Place the console in the cylinder block and tighten bolts -arrows- to 45 Nm.
