ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 9HX - 9HY - 9HZ
Checking and setting the timing (continued).
Turn the engine in the normal direction of rotation until the peg [1]engages in the setting hole.
Peg the flywheel at «b», using tool [1].
Move aside the electrical harness (6).
Remove:
- The engine support (7).
- The screw (8).
- The accessories drive pulley (9).
- The lower timing cover (10).
- The upper timing cover (11).
- The tool [1].
Refit the screw (8).
Rotate the crankshaft to bring the camshaft to its pegging point.
Peg:
- The camshaft at «c», using tool [2]
(oil the pegs).
- The fuel high pressure pump pulley (15)at «f»using a 5 mmdiameter peg.
WARNING: Do not touch or damage the track of the engine speed sensor target (14).

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).
