To remove the distributor cap on models with the TFZ ignition system, turn the cap screws a quarter of a turn.
Alignment of the distributor rotor with the mark on the ignition distributor housing
EZL ignition system
Removing
1. The ignition distributor is installed in a vertical position on the side of the cylinder block.
2. Remove the ground wire from the battery.
3. Set the piston of the first cylinder to top dead center as follows. Unscrew the screws, lift and move the ignition distributor cover to the side without disconnecting the high-voltage wires from it. Locate the location of the alignment mark on the ignition distributor housing, which is a small notch on the top edge of the ignition distributor housing.
4. For the crankshaft pulley bolt, turn the engine crankshaft in the direction of working rotation until the distributor rotor electrode aligns with the mark on the distributor housing.
5. Continue cranking the engine until the top dead center mark on the vibration damper aligns with the pointer on the timing chain cover.
Attention! Align the alignment mark with the pointer very accurately.
6. Check that the distributor rotor is exactly aligned with the mark on the distributor housing. If the distributor rotor is rotated 180°from the mark on the distributor housing, then the piston of the first cylinder is at top dead center on the exhaust stroke. In this case, turn the engine crankshaft one full revolution and align the alignment mark on the vibration damper with the pointer on the timing chain cover.
7. The ignition distributor can now be removed and installed without violating the angle of the ignition timing, if the engine crankshaft is not turned at the same time.
8. Unscrew a bolt of fastening and remove the case of the distributor of ignition from the block of cylinders.
9. Check the condition of the O-ring and replace it if necessary.
Installation
1. If, after removing the ignition distributor, the engine crankshaft was turned, perform the following steps.
2. Unscrew the spark plug from the first cylinder. Close the spark plug hole with your thumb and turn the engine crankshaft until the finger feels pressure in the cylinder. Continue turning the engine crankshaft until the top dead center mark on the vibration damper aligns with the pointer on the timing chain housing.
3. Insert the ignition distributor into the cylinder block and align the distributor shaft with the drive so that the distributor rotor is aligned with the mark on the ignition distributor housing. The ignition distributor housing must be clearly installed on the cylinder block mounting flange, and the hole in the mounting flange for the ignition distributor mounting bolt must be centered in the groove at the base of the distributor housing. Rotate the distributor housing if necessary.
4. Secure the distributor housing with a bolt, tightening it to the required torque.
5. Establish a cover of the distributor of ignition and fix it with screws.

1. The ignition distributor is installed in a vertical position on the side of the cylinder block.
2. Remove the ground wire from the battery.
3. Set the piston of the first cylinder to top dead center as follows. Turn the screws securing the ignition distributor cover a quarter of a turn, lift and move the ignition distributor cover to the side without disconnecting the high-voltage wires from it. Locate the location of the alignment mark on the ignition distributor housing, which is a small notch on the top edge of the ignition distributor housing.

7. The ignition distributor can now be removed and installed without violating the angle of installation of the ignition moment, if the engine crankshaft is not turned at the same time.
8. Remove the hose from the vacuum regulator located on the side of the ignition distributor housing.
9. On the side of the ignition distributor housing, disconnect the electrical connector of the pulse sensor.
10. Using paint, mark the position of the distributor body relative to the mounting flange.
11. Unscrew the mounting bolt and remove the ignition distributor housing from the cylinder block (see fig. Arrangement of a bolt of fastening of the distributor of ignition on models with system of ignition TFZ).
12. Check the condition of the O-ring and replace it if necessary.
