ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 8HX 8HW 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.
