ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 6FZ - RFN
Tensioning the timing belt.
Turn the tensioner roller (8)in the direction of the arrow «c», by means of a hexagonal spanner at «d».
IMPERATVE: The index «a» should go past the slot «g» by an angular value of 10°.
If it does not, replace the tensioner roller or the timing belt and tensioner roller assembly.
Next bring the index «a» to its adjusting position «g», by turning the tensioner roller in the direction of
the arrow «e».
WARNING: the index «a» should not pass the slot «g».
Otherwise, repeat the operation to tension the timing belt.
IMPERATIVE: The tensioner roller should not turn during the tightening of its fixing.
If it does, repeat the operation to tension the timing belt.
Tighten the screw (9)of the tensioner roller (8)to 2,1 ± 0,2 m.daN.
IMPERATIVE: The hexagonal tensioner roller drive should be approx. 15° below the level of the cylinder
head gasket «h».
If it is not, replace the tensioner roller or the timing belt and tensioner roller assembly.

ENGINECHECKING AND SETTING THE VALVE TIMING
Engine: RFK
Tensioning the timing belt.
Turn the tensioner roller (9)anti-clockwise, using a hexagonal spanner at «c».
Place the index «a»in position «e».
IMPERATIVE: The index «a» should go past the slot «f» by an angular value of 10°.
If it does not, replace the tensioner roller or the tensioner roller and timing belt assembly.
Then bring the index «a»to its adjustment position «f», by turning the tensioner roller in the direction
of the arrow «d».
WARNING: The index «a» must not go past the slot «f».
If it does, restart the operation to tension the timing belt.
IMPERATIVE : The tensioner roller must not turn during the tightening of its fixing. If it does
turn, restart the operation to tension the timing belt.
Tighten the screw (10)of the tensioner roller (9)to 2,1 ± 0,2 m.daN.
IMPERATIVE: The hexagonal tensioner roller drive should be at approx. 15° below the level of
the cylinder head gasket «g».
Otherwise, replace the tensioner roller or the tensioner roller and timing belt assembly.

ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 8HX - 8HZ
B1EP18HC
Setting the timing (continued).
Hold the tensioner roller, using a hexagonal spanner at «b».
Slacken the screw (9).
Remove the timing belt (10).
Refitting.
IMPERATIVE: Check that both the tensioner roller and the fixed roller turn
freely
(no tight spots). If this is not the case, replace the rollers.
Fitting of the pulleys.
- Camshaft pulley : Tighten to 4,3 ± 0,4 m.daN.
- Fuel high pressure pump pulley : Tighten to 5 ± 0,5 m.daN.
The crankshaft pinion is located without a screw at the end of the crankshaft.
Fitting of the rollers.
IMPERATIVE: Check that the tensioner roller turns freely
(no tight spot).
Otherwise, replace the rollers.
- Guide roller : Tighten to 4,5 ± 0,4 m.daN.
- Tensioner roller : Pre-tighten to 0,1 m.daN.
Check the condition of the seals at the camshaft and at the crankshaft pinion.

Setting the timing (continued).
Turn the tensioner roller to the right to bring the index «c»to position «d», using
a hexagonal spanner.
Tighten the screw (9)of the tensioner roller, tighten to 3 ± 0,3 m.daN.
Remove the tools [4]and [5].
Rotate the engine ten times
(check that the timing pinion is correctly up against
the crankshaft).
Check:
- The pegging of the camshaft.
- The crankshaft pinion.
- The fuel high pressure pump pinion (15).
- The correct positioning of the index of the dynamic tensioner.
If these are not correct, repeat the operation to position the timing belt.
Refit:
- The engine speed sensor (6).
- The belt retaining stop (5), tighten to 0,7 m.daN.

CHECKING AND SETTING THE VALVE TIMING
Engines: 9HX - 9HY - 9HZ
Checking and setting the timing (continued).
Peg the crankshaft at «e», using tool [3].
Remove:
- The timing belt protector (13).
- The engine speed sensor (14).
Slacken the screw (12)of the tensioner roller and keep it slackened using an allen spanner at «d».
Detension the timing belt by pivoting the tensioner roller
(clockwise).
Remove the timing belt, starting with the coolant pump pinion.
Checks.
ESSENTIAL: Just prior to refitting, proceed to the checks as below.
Check:
- That the rollers and the coolant pump pulley turn freely
(without play and without tight spot).
- That there are no signs of oil leaks (at the crankshaft and camshaft seals).
- That there are no leaks of coolant fluid (at the coolant pump).
- That the track of the engine speed sensor target (14)is not damaged or scratched.
Replace any components that are defective
(if necessary).
