CHECKING AND SETTING THE VALVE TIMING
Engine : XFX
Checking the valve timing setting (continued).
- Peg the crankshaft, using tool[1].
- Check that the tool [2]engages without effort in the cylinder heads at the camshaft pulleys.
- Remove the tools [1] and [2].
Refit :
- The lower timing cover(13).
- The upper timing covers (9)and(10).
- The crankshaft pulley (12).
- The roller / dynamic tensioner assembly (11).
- The power steering pulley.
- Complete the refitting of components.
- Initialise the ignition injection ECU.

INJECTION
PROHIBITED OPERATIONS: HDi DIRECT INJECTION SYSTEM
Engines : RHY - RHZ - 4HX
Cleaning.
- The use of high pressure cleaners is prohibited.
- Do not use compressed air.
Fuel supply circuit.
- Required fuel : diesel.
Electric circuit.
- Swapping injection ECUs Between two vehicles will render it impossible to start either vehicle.
- It is forbidden to supply a diesel injector with 12 volts.
High pressure fuel pump.
Do not separate the following components from the high pressure fuel pump (5):
- Sealing ring (b)(no replacement parts).
- High pressure outlet connector (a)(will cause a malfunction).
PS : HDi = High pressure diesel injection.
