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.
