ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 8HY 8HV
B1EP18YD
Checks (continued).
Refit the screw (8).
Rotate the crankshaft six times
(clockwise).
IMPERATIVE: Never rotate the engine backwards.
Peg:
The camshaft, using tool
[2](oil the pegs).
The fuel high pressure pump pulley (14), using tool [3]at «c».
WARNING:The magnetic track should show no signs of damage and should not be
approached by any source of magnetism.
Peg the crankshaft at
«b», using tool [3].
IMPERATIVE:Should it be impossible to peg the camshaft, check that the
offset between the hole in the camshaft pinion and the pegging hole is not
greater than 1 mm.Otherwise repeat the operation to position the timing belt
(see corresponding
operation)
.

CHECKING AND SETTING THE VALVE TIMING
Engines: 8HY 8HV
B1EP18VD
Setting the timing.
Perform the preliminary operations for checking the timing up to removing tool [1]at «a»for immobiling the
engine flywheel.
Refit screw
(8).
Rotate the crankshaft to bring the camshaft towards its pegging point.
Peg the camshaft, using tool
[2](oil the pegs).
WARNING: Do not press or damage the track which is the target for the engine speed sensor (14).
Peg the crankshaft at «b», using tool [3].
Remove:
The timing protector
(13).
The engine speed sensor
(14).
Slacken the screw
(12)of the tensioner roller, keeping it slack with the aid of a hexagonal spanner at
«c».
Detension the belt by pivoting the tensioner roller
(clockwise).
Remove the timing belt, commencing with the coolant pump pinion.
Peg the pulley
(15), using a 5 mmdiameter peg at «d».
