ENGINECHECKING THE VALVE TIMING
Engines: 9HX - 9HY - 9HZ
Tools.
[1]Flywheel setting peg: (-).0194.C
[2] Camshaft setting peg: (-).0194.B
[3] Crankshaft setting peg: (-).0194.A
IMPERATIVE: Respect the safety and cleanliness requirements specific to High pressure Diesel
injection (HDi) engine versions.
Checking and setting the timing.
Raise and support the vehicle, wheels hanging.
Disconnect the battery.
Uncouple:
- The fuel supply unions (1).
- The air/air heat exchanger inlet and outlet pipes (3).
- The exhaust line at the catalytic converter flexible pipe.
- Disconnect the connecteur at «a».
Remove the accessories drive belt
(see corresponding operation).
Support the engine with a roller jack equipped with a block.
Remove the four screws (5), the three screws (4)and the engine supports (3).
