1. Check that cylinder 1 is at top dead center (TDC on the pulley vibration damper, cylinder 6 in overlap position).
2. Apply clean engine oil to the idler gear and hub.
3. Install the idler gear (7). Make sure that the marks line up with the marks on the camshaft gear (3) and the crankshaft gear (6).
If the crankshaft or the camshaft of an engine is rotated separately without an idler gear (7), the engine’s pistons may touch the valves.
4. Install the thrust plate (4).
5. Fit the idler gear attachment bolt (5) and tighten it to the specified torque.
