Removal and installation of camshafts
Engines BP (DOHC) Withdrawal | - Remove the spark plug, see. Chapter Introduction.
- Remove the cylinder head cover gasket.
- Install the crankshaft position corresponding to the top dead center of the piston of 1st cylinder. See section Removing and installing toothed belt (DOHC).
 | The position of the crankshaft then more should not be changed. |
- Remove the timing belt. See Section Removal and installation of a gear belt of engines VZ, B5, B6 (SOHC), BP (SOHC).
- Remove the ignition distributor, see. Chapter Ignition system, Section Removal and installation of the distributor of ignition.
 | - Hold camshafts key, unscrew the bolts gears. Remove the camshaft gears, if necessary, to bring down the light blows of a rubber hammer.
|
| Gears removed carefully so as not to lose the guide pins. |
- Unscrew the sealing plate.
 | - Check axial play of the camshaft. Desired value: 0.07 - 0.19 mm. The maximum allowable axial play of 0.20 mm. If this value is exceeded, it is necessary to replace the camshaft and possibly the cylinder head.
|
- Mark bearing caps with chalk or felt-tipped pen to when installing them can be established on former places, and in the same position.
 | - Evenly loosen the bearing caps of inlet and exhaust camshafts in several passes in the order shown and remove the cover.
|
- Remove camshafts with old seals.
|
|
Setting | Since the axial clearance is extremely small camshaft, the camshaft during installation must be kept in a horizontal position. To achieve this you must follow these requirements. If the camshaft during installation will be skewed, it can be damaged by the shaft itself or cylinder head. |
| - To cover all the places camshaft supports a small amount of engine oil.
- Insert camshafts.
 | - Apply a shaded place sealant based on silicone (eg, DOW CORNING Q3-7057).
|
| On neck bearings applied sealant should not. |
- Install all bearing caps according to the labeling.
 | - Tighten bearing caps with a torque wrench in the above sequence. Tightening is carried out in two passes.
|
- 1st pass: 10 Nm
- 2nd pass: 15 Nm
- Lubricate camshaft seals and their place of landing a small amount of engine oil. Carefully score the gland pipe of the same diameter. Score gaskets so that they are flush with the cylinder head.
| Seals during installation not to warp. |
- Install a sealing plate and tighten the bolts with a force of 10 Nm.
- Clear camshaft gear from oil and water.
 | - Rotate camshafts to guide pins are facing upward.
|
- Install the camshaft gears up marks I (inlet side), E (the outlet side).
- Tighten the camshaft with a force of 60 Nm. In this case, hold the wheel wrench.
| When tightening camshaft not to damage the cylinder head key. |
- To establish and pull the toothed belt, see. Section Removal and installation of a gear belt of engines VZ, B5, B6 (SOHC), BP (SOHC).
 | - Apply a shaded place sealant based on silicone (eg, DOW CORNING Q 3-7057).
|
- Install the cylinder head cover gasket and tightened to 10 Nm.
- Set the ignition distributor, see. Chapter Ignition system, Section Removal and installation of the distributor of ignition.
