Carry out removal of the distributor of ignition in the following order:

– disconnect ignition;

– install the lever of gear shifting in neutral situation, and tighten the emergency brake;

– install the piston of the first cylinder of the engine in VMT on a compression step, for this purpose use one of receptions:

– remove spark plugs, then turn a bent shaft of the engine clockwise, for a belt pulley;

– include the 4-or 5 transfer and move the car;

– raise a forward part of the car and by the included transfer turn a forward wheel;

– close an opening of a spark plug of the first cylinder a finger or a wooden stopper;

– when the piston of the first cylinder approaches VMT at the end of a compression step, pressure upon a stopper will increase;

– remove a stopper with an ear from the top part of a case of coupling and continue to turn a bent shaft of the engine before combination of a tag of VMT on a flywheel and the index (fig. 6.11) . Tags on a flywheel to the left of a tag of VMT are intended for installation of a corner of an advancing of ignition;

– check the provision of tags of VMT:

– the groove on a pulley of a bent shaft has to be combined with an arrow in the lower cover of the drive and VMT tag on a back surface of a pulley of the camshaft;

– VMT tag located from a reverse side of a pulley of the camshaft has to coincide with the upper edge of a head of the block of cylinders, otherwise turn a bent shaft on one turn;

– note position of the case of the distributor;

– if necessary disconnect high-voltage wires from a distributor cover;

– remove brackets of fastening and a cover of the distributor. If is available, raise and remove a plastic cover at the distributor basis. The cover at the same time collapses;

– disconnect a vacuum hose of 20 (fig. 6.12) from the vacuum regulator 16 of an advancing of ignition;

Fig. 6.14. Combination of contact of the runner with a tag on the distributor case

– check whether there is a tag on the top part of the case of the distributor (see fig. 6.14 ) which has to be on the center of a rotor of the distributor. In the absence of a tag, put it with a pencil;

– turn off fastening bolts in the distributor basis, then remove the distributor from the engine;

– check a condition of a sealing ring 19 on the basis of the distributor (see fig. 6.13 ).

PREVENTION Do not change the provision of a bent shaft of the engine at the removed ignition distributor.

Dismantling and assembly of the distributor of ignition is carried out in the following order.

Distributors of ignition of the Digifant system and TC1-H:

– clear the ignition distributor;

– remove a rotor of 1 distributor from a shaft and a dustproof cap 2 (see fig. 6.12 );

– note position of the steel screen 5 with cuts of rather power shaft;

– remove a lock ring 3 and take the steel screen 5 with cuts together with an adjusting pin 4;

– remove flat and spring washers 6, at the same time note their arrangement for repeated installation on the places.

– unscrew screws and remove the vacuum regulator 16 of an advancing of ignition;

– take a lock ring and a washer of fastening of the support plate, unscrew the screws fixing the electric socket to the case of the distributor and remove the sensor 12 of Hall and the electric socket 11;

– unscrew side screws, remove the support plate 14, a persistent washer and spring brackets;

– clear all details and check their state;

– examine an internal part of a cover of the distributor on existence of signs of an erosion;

– check smoothness of movement of a coal brush;

– check a condition of a rotor of 1 distributor;

Fig. 6.15. Check of resistance of a rotor of the distributor

– measure by a tester distributor rotor resistance between the central and side contacts which has to make 600–1400 Ohms (fig. 6.15) ;

– check operability of the vacuum regulator of an advancing of ignition for what create vacuum on the union of the regulator and check movement of draft of the vacuum regulator of an advancing of ignition;

– collect the ignition distributor in the sequence to the return dismantling. Grease the working surface of the bearing of the support plate.

FEI distributor and KE-Motronic. On the FEI and KE-Motronic distributor (fig. 6.16) it is possible to make only replacement of the sensor of Hall 5 which is delivered in the set consisting of the coupling 9 of the drive, a pin 7 and a lock ring 8;

– the rotor of the distributor is pasted to a shaft 1 and for replacement it needs to be destroyed, and to paste a new rotor glue;

– note the provision of shift of the coupling 9 of the drive concerning a distributor rotor;

– fix the drive coupling in a vice, then beat out a cylindrical pin 7 and remove a lock ring 8;

– remove the coupling 9, laying and a plastic washer 9;

– remove a shaft 1 with a distributor rotor, a plastic protivopylevy cap, laying and a plastic washer;

– unscrew screws 4 and take Hall's sensor 5 of the distributor case;

– install the new sensor of Hall in the sequence, the return to removal.

Carry out installation of the distributor of ignition in the following order:

– turn a distributor rotor from a starting position (VMT) clockwise and install the distributor over an opening in the block or a head of the block of cylinders according to previously put tags on the case and the block and install the distributor into place;

– on SOHC engines install the distributor into place and check that the rotor of the distributor moved counterclockwise to a starting position. If the distributor is not installed in a starting position, remove the distributor and the screw-driver turn a power shaft of the oil pump, then again install the ignition distributor;

– check combination of earlier put tags and fix the distributor by a bolt on SOHC engines or two bolts on DOHC engines;

– establish a distributor cover together with the central cover and connect wires;

– connect a vacuum hose to the ignition advancing regulator;

– check and, in case of need, adjust an ignition advancing corner (see section 6.10).
