CHECKING AND SETTING THE VALVE TIMING
Engines: 6FZ - RFN
Refitting (continued).
Remove the tools [1]and [2].
Rotate the crankshaft ten times
(normal direction of rotation).
IMPERATIVE: No pressure or outside force should be brought to bear on the timing belt.
Peg the inlet camshaft pulley, using tool [1].
Checks.
Tension of the timing belt.
ESSENTIAL: Check the position of the index «a», which should be opposite the slot «g».
If the position of the index «a» is not correct, repeat the operations to tension the timing belt.
Refit the upper timing cover (1).
Clip the fuel delivery hose on the timing cover.
Refit the accessories drive belt
(see corresponding operation).
Lower the vehicle.

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.

Engines: 8HX - 8HZ
B1EP18KC
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.
