Withdrawal

PERFORMANCE ORDER

1. Remove the cylinder head cover, gas distribution belt and sprocket camshafts. If you remove the shafts from the front cylinder head, remove the ignition distributor (model 1997 and earlier model years). If you shoot the camshafts from the back of the head, then remove the inlet manifold. A warning Before removing the camshaft bearing caps, align the positioning pins shafts tagged on the end caps. 2. On the front of the cylinder head, align the dowel pin (A) exhaust camshaft with the mark on the end cap (B) and labeled with an asterisk sinhranizatsionnoy shaft (C). 3. On the back of the cylinder head, align the dowel pin (A) of the inlet camshaft with a label on the end cap (B). 4. Loosen the screws end caps shafts in stages (on 1/4 turns). Loosen the first two external bolts, and then the two internal (in the rear head and there is a bolt (B) to be weakened in the last turn. 5. Remove the camshaft seals. 6. Using the specified sequence, loosen in stages (on 1/4 turns) bolts of covers of bearings of camshafts (see. Fig. Sequence of easing of bolts of covers of bearings of camshafts (front cylinder head) and fig. Sequence of easing of bolts of covers of bearings of camshafts ( the rear cylinder head)). 7. Remove the cover and camshafts. 8. Fold the bearing caps in order.

If necessary, remove the valve lifters with a magnet. Fold the pushers in order. Hydraulic jacks (models 1997 and earlier) should keep upside in clean engine oil.

Check

Inspect the camshafts and tappets (see. Subsection 3.1.10).

Setting

PERFORMANCE ORDER

1. Apply pushers molybdenum grease and install them on the spot. 2. Apply molybdenum grease on the cams and necks of bearings of camshafts. 3. Install the shaft to the head, and align the label synchronization gears with shafts. 4. Apply sealant to the outer edges of the front shaft bearing caps. 5. Align the mounting pins with the drive shafts synchronization marks and install thrust plates of camshafts, having tightened their bolts (see. 6. Install all bearing caps shafts. 7. Using the specified sequence, tighten in several stages (on 1/4 turns) bolts of covers (see. Fig. Sequence of a tightening of bolts of covers of bearings of camshafts (front cylinder head) and fig. Sequence of a tightening of bolts of covers of bearings of camshafts (rear cylinder head )). 8. Lubricate the new oil seal camshaft engine oil and set it in place. 9. Replace the caps, sealant smeared on the front of the driven camshafts. 10. Install the remaining components in reverse order.
