Camshaft / timing gear
SOHC engine with 16 valves SOHC engine with 16 valves
| - Check axial play of the camshaft. Required value:
- Engines OT, B6 (SOHC): 0, 04-0, 13 mm
- Engines BP (SOHC): 0, 06-0, 20 mm
- Engines BSE, B5, V6E: 0, 05-0, 18 mm
- If the values do not meet the requirements, replace the bearing plate, and possibly also the camshaft.
 | - Hold camshaft key, unscrew the bolt gear camshaft. Remove the gear if necessary to bring down the light blows of a rubber hammer.
|
 | To remove the camshaft gear carefully so as not to lose the guide pin. |
 | - Unscrew the thrust plate and remove the camshaft through the hole of the distributor.
|
- Knock old camshaft oil seal using a punch.
| This should not be damaged by the landing gland. |
|
|
Setting | - Lubricate the landing site and the camshaft oil seal a small amount of engine oil. Carefully score the seal using the pipe of the same diameter in place. Score gland so that it is flush with the cylinder head.
| Gland during installation not to warp. |
- Lubricate the camshaft bearing all the places a small amount of engine oil.
- Carefully insert camshaft into the cylinder head through the hole of the distributor.
| When retracted, the shaft should not warp. Carefully move in through the gland, so as not to damage the sealing lip. |
- Install the camshaft so that the pressure plate can get in the groove of a cam. Screw the thrust plate with a force of 10 Nm.
- Insert the guide pin in the camshaft. Install the wheel of a cam so that the guide pin engages the groove.
- Hold the key to screw cam camshaft gear with a force of 60 Nm.
| While holding the shaft as not to damage the cylinder head with a wrench. |
- Check whether the cost of a crank and camshafts on labels ignition cylinder 1 and adjust if necessary. See Section Removal and installation of camshafts.
 | - Tighten bearing caps with a torque wrench in the specified sequence. Tightening should be carried out in two passes.
|
- 1st pass: 15 Nm
- 2nd pass: 25 Nm
- Clean the wheel of a cam of water and oil.
- To establish and pull the toothed belt, see. Section Removal and installation of a gear belt of engines VZ, B5, B6 (SOHC), BP (SOHC).
- If there is, install the cylinder head mechanical fuel pump, see chap. The power supply system, the carburettor, fuel injection system, Section Removal and installation / check of the fuel pump.
- If the engine is not equipped with hydraulic tappets, check valve clearance. See Section Checking / adjusting valve clearance.
- Install the cylinder head cover gasket. See Section Removal and installation of the cylinder head / replacement of the cylinder head gasket.
- Set the air filter, see chap. The power supply system, the carburettor, fuel injection system, Section Removal and installation of the air filter.
- Screw the battery holder with a torque of 20 Nm.
- Install the battery. See section Removing and installing the battery.

Removing the diesel engine 1, 7 l | With the removed gear belt wheel to rotate the camshaft must not otherwise be met with piston valves. |
| - Remove toothed belt, see. Chapter diesel engine.
- Unscrew the rear casing of a gear belt.
 | - Remove the spring rocker arms.
|
- Marked rockers to when installing them can be installed in its place.
- Remove rocker arms from their seats.
 | - Check axial play of the camshaft. Desired value: 0, 02 - 0,18 mm. The maximum allowable axial play: 0, 20 mm. If this value is exceeded, it is necessary to replace the cam and possibly the cylinder head.
|
 | - Unscrew pressure plate -1-.
|
- Unscrew the support bracket 3 -2-lift camshaft with cam -3.
- Remove the front support bracket to the camshaft oil seal -4- and remove with a screwdriver.
