7. CHECK ENGINE TIMING
7.1.
NON VVT ENGINES
7.1.1.
Set the engine to TDC No.1 cylinder. Insert the VSE5006-04 Camshaft Sprocket Locking Tool.
7.1.2.
Check that the timing lines correspond with the line on the Camshaft Sprocket Locking Tool and the mark on the crankshaft sprocket is
opposite the marker on the housing. If the marks are not aligned then it will be necessary to adjust the timing.
7.2.
VVT (XER) ENGINES
7.2.1.
The procedure is similar to that of the non VVT engines, but the VVT engines have dots instead of lines as described earlier (section
5.7.1.) which do not line up exactly with the centre line on the VSE5006-04 Camshaft Sprocket Locking Tool.
7.2.2.
Remove the cylinder head cover and insert the VSE5006-05 Camshaft Setting Plate into the slots at the rear of the camshafts (fig.8)
to see if the camshafts are aligned correctly. Check that the timing dots are aligned and the mark on the crankshaft sprocket is
opposite the marker on the housing (fig.9).
7.2.3.
If the timing dots are not correctly aligned, the Camshaft Setting Plate cannot be inserted or the mark on the crankshaft sprocket is
misaligned then it will be necessary to adjust the timing.
8. ADJUST ENGINE TIMING
8.1.
NON VVT ENGINES
8.1.1.
Timing adjustment is achieved by removing the timing belt, correctly aligning the crankshaft sprocket and the camshaft sprockets and
re-fitting the timing belt.
8.1.2.
Remove the timing belt as described in section 5.
8.1.3.
If the camshaft sprockets are misaligned, adjust so that the timing marks are directly opposite. Use the centre line on the VSE5006-04
camshaft Sprocket Locking Tool to check the alignment (fig.10) and check that the mark on the crankshaft sprocket is aligned with the
marker on the housing (fig.11).
NOTE: The flywheel holding tool will have to be removed before rotating the crankshaft sprocket.
8.1.4.
Once all timing marks are correctly aligned, fit the flywheel locking tool and re-fit the timing belt as described in section 6.
8.1.5.
Remove Camshaft Sprocket Holding Tool and Flywheel Holding Tool.
8.1.6.
Rotate the engine in the direction of rotation for 2 full cycles and return to TDC No.1 cylinder.
8.1.7.
Check the position of the timing marks on the camshaft sprockets and fit the Camshaft Sprockets Locking Tool to confirm that the
engine timing is correct.
8.1.8.
Remove Camshaft Sprockets Locking Tool, remove Flywheel Locking Tool and re-fit components as described in section 6.

8.2.
VVT (XER) Engines
NOTE: The ignition module will need to be removed from the top of the engine to allow access to the camshafts.
8.2.1.
Remove the timing belt as described in section 5.
8.2.2.
Remove the cylinder head cover and adjust the position of the cams so that the VSE5006-05 Camshaft Setting Plate can be inserted
into the slots at the rear of the camshafts. Check that the timing dots on the camshaft sprockets are in the correct position (fig.11).
8.2.3.
Check that the mark on the crankshaft sprocket aligns with the marker on the housing (fig.9) If the position of the crankshaft needs to
be adjusted in will be necessary to remove the Flywheel Holding Tool.
8.2.4.
Once all timing marks are correctly aligned, re-fit the Flywheel Holding Too and re-fit the timing belt as described in section 6.
8.2.5.
Remove Camshaft Sprocket Holding Tool and Flywheel Holding Tool.
8.2.6.
Rotate the engine in the direction of rotation for 2 full cycles and return to TDC No.1 cylinder.
8.2.7.
Check the position of the timing dots on the camshaft sprockets and fit the Camshaft Sprockets Locking Tool and the VSE5006-05
Camshaft Setting Plate to confirm that the engine timing is correct.
8.2.8.
Remove camshaft sprockets locking tool and the camshaft setting plate, and re-fit components as described in section 6.
