Removal
With the front timing belt cover removed, set the engine in its correct timed position,
inserting special tool 18G 1570 to lock the front camshaft gears.
• Using 18G 1521 to restrain the rear camshaft gear, loosen and remove both bolts
securing each camshaft gear.
• Mark D.O.R. on belt if it is to be re-used, and ease gears with belt from the camshafts.

Refit
• Make sure gear to camshaft mating faces are clean and dry.
• Fit inlet gear to camshaft and align the timing mark on the gear with the mark on the
backplate.
• Using finger pressure only, fit exhaust camshaft gear and timing belt together, ensuring
that the gear is correctly aligned with the dowel on the camshaft.
• Using a straight edge, check the alignment of the timing marks on the camshaft gears
with the mark on the backplate.
• Fit camshaft gear retaining bolts, then restrain gears from turning with 18G 1521 and
tighten bolts to 65Nm.
• Make sure the timing belt is positioned centrally around the gears, and re-check the
alignment marks using the straight edge.
• Remove 18G 1570 from the front camshaft gears and refit remaining components.
NOTE: The same torque setting, 65Nm, also applies to the front camshaft gear retaining
bolts.
