Install timing belt.
Ensure that belt is tight between crankshaft and in-take pulley, if not reinstall.
Tighten the center screw to 5 Nm (4 ft.lb) .
Holding the center screw stationary, turn the eccentric (A) with a 6 mm allen wrench COUNTER-clockwise until the tension indicator passes the right side of the adjustment window (B).
Turn the eccentric (A) back CLOCKWISE until the indicator (C) reaches the correct position based on the temperature of the engine (see Fig 1).
Hold the eccentric secure and tighten the center screw to 20 Nm (15 ft.lb) .
NOTE: When setting the final adjustment the needle (C) must enter the adjustment window (B) from the right. If the needle exits the window to the left, it must be readjusted past the window so that it enters from the right.
Press on the timing belt and verify that the indicator moves in response to the pressure.
Press the camshaft belt and check that the belt tensioner needle moves freely.
NOTE: If the bolts holding either cam wheel had been loosened, tighten them at this time to 20 Nm (15 ft.lb) .
