ENGINECHECKING AND SETTING THE VALVE TIMING
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.

ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 9HX - 9HY - 9HZ
Checking and setting the timing (continued).
Refitting.
Fit the timing belt on the crankshaft pinion.
Position the belt on the guide roller, belt well tensioned.
Refit:
- The timing belt protector (13).
- The engine speed sensor (14).
Reposition the timing belt, strip «f»well tensioned, in the following sequence:
- Guide roller (17).
- Camshaft pulley (16).

CHECKING AND SETTING THE VALVE TIMING
Engines: 9HX - 9HY - 9HZ
Adjusting the timing belt tension.
Act on the tensioner roller (18)to align the marks «j»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 «j» 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 «j»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].
