Adjusting the timing belt tension.
Act on the tensioner roller (18)to align the marks «g»and «h», avoiding detensioning the
timing belt, using an allen spanner at «d».
Should this fail, repeat the operation to tension the timing belt.
Hold the tensioner roller (18).
Tighten the tensioner roller fixing nut to 3,7 ± 0,3 m.daN.
Check the position of the tensioner roller
(the alignment of the marks «g»and «h»should
be correct).
Remove tools [2] and [3].
Rotate the crankshaft six times
(clockwise).
IMPERATIVE: Never rotate the engine backwards.
WARNING: Do not touch or damage the track of the target of the engine speed sensor
(14).
Peg the crankshaft, using tool[3].
Check the position of the tensioner roller
(the alignment of the marks «g» and «h»should
be correct).
If this is not the case, repeat the operation to tension the timing belt.
Peg the camshaft pulley, using tool [2].
IMPERATIVE: Should it be impossible to peg the camshaft, check that the offset
between the camshaft hole and the pegging hole is not more than 1 mm. If the offset
is too great, repeat the operation.
Remove tools [2] and [3].
