16-valve engines
To perform the work, you will need a special tool to hold the camshaft pulleys.
Note: The work can be done without this device. Unscrewing the camshaft pulley mounting bolts is usually possible without difficulty
Sequence of execution
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. Remove the front timing belt cover (see "Timing Belt - Replacement").
3. If there is a special tool for holding the camshaft pulleys, remove the timing belt (see "Timing Belt - Replacement") and, alternately holding the camshaft pulleys with this tool, with a key by 17 mm we unscrew the bolts that secure them.
If there is no device, use a socket wrench by 17 mm loosen the bolts securing the camshaft pulleys, holding them with a wrench at 17 or 19 mm crankshaft from turning by the bolt of its pulley (or by engaging fourth gear and setting the car to the parking brake).
4. Remove the timing belt (see "Timing Belt - Replacement").
5. Unscrew the pulley mounting bolts and remove the intake valve shaft pulley.
6. Remove the exhaust valve shaft pulley.
7. To avoid losing them, remove the keys from the shaft grooves.
8. Install the pulleys in the reverse order, making sure that the keys enter the pulley grooves. After installing the pulleys, install the timing belt (see "Timing Belt - Replacement") and adjust its tension (see "Timing Belt - Checking Condition and Adjusting Tension").
8-valve engines
To complete the work you will need: a socket wrench by 10 mm, key by 17 mm.
Sequence of execution
1. Remove the timing belt (see "Timing Belt - Replacement").
2. With a socket wrench by 10 mm, put on the nut of the rear timing belt cover, we hold the camshaft pulley from turning, with a key by 17 mm unscrew the pulley mounting bolt.
3. Remove the pulley from the shaft.
4. Remove the key from the groove.
Warning: When performing the following operation, do not scratch the working surface of the shaft
5. Install the pulley in the reverse order, while
make sure that the key has entered the pulley groove. After installing the pulley, install the timing belt (see "Timing Belt - Replacement") and adjust its tension (see "Timing Belt - Checking Condition and Adjusting Tension").
