Fig. 3.108. Selector lever



Check an emphasis and stoppers of cams on lack of wear.
Check automatic transmission selector lever plugs for lack of wear or damage.
Check a spring for lack of damage or wear.
Check a core tip assembled for lack of wear.

NOTE
When carrying out maintenance of system of blocking of the lever of the automatic transmission selector follow the instructions and procedures of adjustment given below to provide correctness of work of system.

Procedure of installation of a blocking cam

Fig. 3.109. Installation of the blocking cam of a key of the lock of ignition it is located in situation "B"


Move the blocking automatic transmission selector lever cam in the direction "A" and hold it a hand in this situation (see fig. 3.109).
Check that the blocking cam of a key of the lock of ignition is located in situation "B" and is kept by a persistent pin (fig. 3.109).

Procedure of adjustment of a cable of blocking of the lever of the selector and cable of blocking of a key of the lock of ignition

Fig. 3.110. The provision of the blocking cams


Check that both blocking a cam are established in the situation shown in the figure 3.110.
Establish cables of blocking of the lever of the selector and a key of the lock of ignition in the specified situation. At the same time other end of a cable of blocking of a key of the lock of ignition the cable of blocking of the lever of the selector – on a brake pedal in the relevant provision has to be recorded in the ignition lock, and.
Temporarily connect both cables to the automatic transmission selector lever, as shown in the figure 3.111.
Reliably fix each cable on a pin of the corresponding blocking cam.
Check that the tip of a cable of blocking of the lever of the selector concerns a pin of the blocking selector lever cam, then record a nut an external braid of a cable on an arm, and a cable tip – a washer and the forelock.
Slightly press the blocking ignition lock key cam in the direction specified by the arrow "Q".

Fig. 3.111. Selector lever cables


Slightly pull a cable of blocking of a key of the lock of ignition in the direction specified by the arrow "G" to pull a cable, and then record an external braid of a cable a nut (see fig. 3.111).
Make sure that the tip of a cable of blocking of a key of the lock of ignition is put on a pin of the blocking cam of a key of the lock of ignition and then record it a washer and a stopper. At the same time check that the cable of blocking of the lever of the selector is fixed on the blocking selector lever cam, as shown in the figure 3.112.

Procedure of check of correctness of installation of blocking of the lever of the automatic transmission selector
When the lever of the automatic transmission selector is in situation "P", at the released brake pedal the blocking button on the lever cannot be pressed (the lever of the automatic transmission selector cannot move from situation "P" to other situation). The button of blocking works in other provisions of the lever of the automatic transmission selector (except "Р").
If the pedal of a brake is pressed (the pedal course within 15–25 mm) when the automatic transmission selector lever in situation "P", then the button of blocking works without restrictions and the selector lever smoothly moves from situation "P" to other situation.
If the pedal of a brake is released, the automatic transmission selector lever smoothly, without jammings moves to situation "P" from any other situation.
The pedal of a brake has to move to all provisions smoothly, without jammings.
When the ignition lock key in the provision of "LOCK", the blocking button on the lever of the automatic transmission selector works even at the released brake pedal.
The key of the lock of ignition does not turn in the provision of "LOCK" when the lever of the automatic transmission selector is installed in situation, excellent from "Р".
If the lever of the automatic transmission selector is installed in situation "P", the key of the lock of ignition turns in the provision of "LOCK" without jamming.

Instructions to maintenance

Fig. 3.112. Check of a cable of blocking of the lever of the selector


Slightly pull a cable of blocking of the lever of the selector in the direction specified by an arrow "E" to create a gap of 2-4 mm between the blocking cams of a key of the lock of ignition and the lever of the automatic transmission selector, and then record a nut an external braid of a cable on an arm. After that check that the gap corresponds to the range of 2-4 mm (see fig. 3.112).

NOTE
If the specified gap does not correspond to the range of 2-4 mm, press a brake pedal stronger, than it is required for permission of the translation of the lever of the automatic transmission selector from situation "P" in other situation.

Check lack of sagging of a cable of blocking of a key of the lock of ignition.

NOTE
If the cable of blocking of a key of the lock of ignition sags, then the key of the lock of ignition cannot be taken out from a larva of the lock of ignition and the lever of the automatic transmission selector can move from situation "P" to other situation even if the key of the lock of ignition is established in the provision of "LOCK".


Fig. 3.113. The provision of the blocking cams of a key of the lock of ignition and the lever of the selector


Before and after implementation of the specified procedures the blocking cams of a key of the lock of ignition and the lever of the selector should not settle down in identical situation, as shown in the figure 3.113.

NOTE
If the blocking cams of a key of the lock of ignition and the lever of the selector are located in identical situation, then the translation of the lever of the automatic transmission selector from situation "D", "3", "2", "L" in situation "P", "R", "N" with effort can lead to damage of the corresponding details.

Transfer the automatic transmission selector lever from situation "D", "3", "2", "L" to situation "P", "R", "N" after turn of blocking ignition lock key cam in the direction specified by an arrow "A".
Transfer the automatic transmission selector lever from situation "D", "3", "2", "L" to situation "P", "R", "N" after turn of the blocking selector lever cam in the direction specified by an arrow "A" at the pressed brake pedal.

Installation of the device of blocking of a key of the lock of ignition
There can be a situation when the key of the lock of ignition cannot be taken out from an ignition lock larva because of the wrong installation of a cable of blocking of a key. For prevention of emergence of the specified situation follow the instructions given below when carrying out maintenance.

Assembly of the lock of ignition and cable of blocking of a key of the lock of ignition
The lock is assembled put on a steering column. Establish an ignition lock larva on the lock of a steering column in the provision of "LOCK".
Connect a cable of blocking of a key to the lock of ignition and fix by the adjusting screw.

Assembly of a cable of blocking of a key of the lock of ignition and lever of the automatic transmission selector
Install the automatic transmission selector lever in situation "P".

Fig. 3.114. Scheme of connection of a cable of blocking of a key of the lock of ignition


Connect a cable of blocking of a key of the lock of ignition, as shown in the figure 3.114, then temporarily fix an external braid of a cable by a nut (M8) so that the adjusting plate of an external braid of a cable moved by effort of retraction of the last.
Holding a tip of a cable of blocking of a key of the lock of ignition and an adjusting plate of an external braid of a cable, move them in the direction specified by the arrows "F" so that on site "B" there was no bend or sagging of a cable.

NOTE
Do not pull a cable in the direction specified by the arrow "X" to remove sagging of a cable. It can lead to a situation when the key of the lock of ignition cannot be taken out from an ignition lock larva.

Tighten a nut (M8) of fastening a cable of blocking of a key of the lock of ignition.
