Camshafts
1. Wrench (for turning camshafts); 73. Control circuit; 75. Intake camshaft gear 76. Exhaust camshaft gear; 77. Exhaust camshaft; 78. Intake camshaft; 79. Camshaft bearing cap; 79a. Mounting bolt
Control
1. Set cylinder 1 to 20°after TDC. Note: in this position (20°after TDC) it is possible to turn the camshafts with the control chain removed without the valves coming into contact with the piston base.
2. Remove the cylinder head cover.
3. Lock the camshafts. To do this, insert the fixing pins (01) through the hole (arrow) in the bearing cap of camshafts 1 and 6 into the bore of the camshaft flange. If it is not possible to insert the locking pins, adjust the basic positions of the camshafts.
Attention! For the 2.2L engine, turn the camshaft adjuster near the intake camshaft gear (75) into position "spat" (late) against the stop in the direction of rotation of the camshaft (arrow).
Adjustment
1. Cylinder 1 is at 20°after TDC and the cylinder head cover has been removed.
2. Remove the front covers.
3. Remove the chain tensioner.
4. Unscrew the exhaust camshaft gear with a T40 socket wrench while holding the camshaft against the hex. Remove the camshaft gear.
5. Remove the control chain from the exhaust camshaft gear.
6. Turn the camshafts with a wrench until the locking pins can be inserted.
7. Install the sprocket and apply the chain.
8. Install the chain tensioner.
9. Recheck the basic position of the camshafts. Repeat the adjustment if necessary.
10. Install the front camshaft covers.
11. Install the cylinder head cover.
