Let's consider removing the steering wheel with an airbag, since without an airbag, removing the steering wheel is not particularly difficult and is performed in the same way as on models 2108-2110
To complete the work, you will need a special puller to remove the airbag and a new steering wheel nut.
If you don’t have a puller, you can make one from an old slotted screwdriver with a blade width of 5-6 mm; to do this, you need to make a small groove in the middle of the blade.
Remove the terminal from the negative terminal of the battery.
On a vehicle equipped with an airbag, to prevent the airbag from deploying, wait at least five minutes after disconnecting the battery before continuing to operate.
Gas generator module (rear view): 1 - gas generator; 2, 4 - hooks for fixing MNPBB; 3 - contacts of the sound signal switch; 5 - location of the identification label; 6 - gas generator igniter connector; 7 - body, with an inflatable cushion folded in it; 8 - hooks for positioning the MNPBV; 9 - facing cover
The driver's airbag is mounted on the steering wheel with two plastic hooks 2 and 4, Figure 1, and two positioning hooks 8.
Steering wheel: 1 - MNPBV mounting bracket; 2 - holes in the bracket for fixing the MNPBV; 3 - holes in the steering wheel for positioning the MNPBV
The pillow hooks fit into the holes in the bracket for fixation 2 and are fixed with spring clips. The airbag latches fit into recesses 3 on the steering wheel.
Set the steering wheel to the “straight” position and, removing the key from the ignition switch, fix this position.
Use a thin flat screwdriver to pierce the hole marked on the steering wheel.
We also pierce a hole on the other side of the steering wheel.
Use two screwdrivers to press out the spring clips through the holes (in the picture with the airbag removed), pulling the pillow towards you, we disengage the hooks of the pillow from engaging the clamps on the steering wheel.
Pull the cushion towards you, overcoming the resistance of the clamps, and remove it from the recesses of the steering wheel.
Move the airbag away from the steering wheel
Disconnect the horn wire ends
Pry it up with a screwdriver and pull the lock out of the wire block
Disconnect the wire block from the airbag connector
Removing the airbag
The removed airbag should be stored in a place protected from moisture and excessive heat, with its cover facing up.
Installing the airbag is done in reverse order.
Connect the wire block to the airbag connector, insert the lock into the block.
Connect the wire lugs to the terminals of the signal switch.
Install the cushion on the steering wheel so that the clips of the cushion fit into the recess of the steering wheel, and the hooks of the cushion fit into the recess of the steering wheel into the corresponding holes in the steering wheel.
Press the cushion until the cushion hooks snap into place with the steering wheel latches.
In a factory or car service, plastic wedges are used to remove airbags (Figure 10).
Using a device for removing the MNPV (view with the MNPV removed); 1, 2 - device 67.7812-9702 for removing MNPBV; 3 - mounting bracket MNPBV
And devices for removing pillows are used (Figure 11).
Place the removed airbag module with the actuator down and away from the workplace.
Removing the steering wheel: 1 - steering wheel; 2 - steering wheel fastening nut; 3 - rotating connector device; 4 - transport fuse
Set the front wheels of the car to the straight-line position.
Use a 24mm socket to unscrew the steering wheel mounting nut
We mark the position of the steering wheel relative to the shaft, for which we use a core to put a mark on the shaft opposite the triangle mark on the steering wheel
Tighten the steering wheel nut a few turns to avoid injury when the steering wheel is suddenly released
Wiggle, pull the steering wheel towards you and remove it from the shaft splines
Unscrew the steering wheel fastening nut and block the drum device from turning
To do this, remove the blocking plate from the holder on the steering wheel
Insert the blocking plate through the hole in the steering wheel hub into the slot of the drum device until it stops
And remove the steering wheel by passing the wire and horn blocks through the hole in the steering wheel hub
Installing the steering wheel
Install the steering wheel in the reverse order, aligning the previously made marks and installing a new self-locking nut.
Steering wheel mounting nut with a torque of 32-51 Nm (3.2-5.2 kgf m).
If it is necessary to install the steering wheel in a new position (for example, if the spokes are inclined when the car is moving in a straight line), put the wheel on the shaft and secure it with a nut without tightening it completely.
After driving straight a few meters, make sure it is in the correct position.
If necessary, move the steering wheel to the required number of splines and tighten the nut.
Installing the airbag is done in reverse order.
Connect the wire block to the airbag connector, insert the lock into the block.
Connect the wire lugs to the terminals of the signal switch.
Install the cushion on the steering wheel so that the cushion clamps fit into the recess of the steering wheel, and the hooks of the cushion fit into the corresponding holes in the steering wheel.
Press the cushion until the cushion hooks snap into place with the steering wheel latches.
