Engine : RFN # 2003
Fitting tension of the timing belt.
Remove the tool [3].
(D) : Maximum position.
(E) : Nominal tension position.
Using the hexagonal key (C), turn the hub of the roller (anti-clockwise), to bring the index (10) to position (D) so as
to tension the belt to the maximum.
Turn the eccentric hub (8) of the roller (9) (clockwise), until the cursor (10) just comes into contact with the peg [4].
IMPERATIVE : Never turn the eccentric hub (8) by a complete rotation if the tool [4] is in position.
NOTE : This operation enables you to place the index (10) in the nominal position (E).
Tighten the screw (7) to 2 ± 0,2 m.daN holding the roller with the aid of the hexagonal key (C).
Remove pegs [1], [2] and [4].
Checks.
Turn the crankshaft by two rotations (direction of engine rotation).
IMPERATIVE : Never rotate the crankshaft backwards.
Make sure that the timing is correctly set by refitting the pegs [1] and [2].
Remove pegs [1] and [2].
Rotate the crankshaft ten times (direction of engine rotation).
Check the position of the index (10).
If the tensioner index is not at its adjusting position (E), recommence the operation to tension the timing belt.
