  4. Loosen the four fixing screws on the front parties of a door.
  5. Remove a support of assembly knots of a door upwards.

Dismantling of the external handle of a door

1 – a drum of the lock with a heating element;
2 – the door handle;
3 – a rotary latch;

4 – the decorative panel;
5 – fixing bolt TORX ahead.
By arrow the spring clip of an operating bar of disconnecting contact is shown.

Operating bar of the lock with following details

1 – the lever of a drum of the lock;
2 – a spring clip;
3 – a bar;

4 – an operating spring clip;
5 – the switching off lever of the lock.

Стеклоподъемник it is visible from the back party on functional model:

1 – the top directing roller;
2 – the directing tyre window lifterа;
3 – the support has flown down;

4 – the engine window lifterа.
Arrows – screw connections of glass/steklopodemnika.

In a photo screws (1 and 2) which should be weakened for a detachment of both parts of a door are shown.

The door lock hangs only on two screws (1 and 2). But at preliminary works on lock dismantle considerable volume since it is necessary to dismantle a support of assembly knots from a door basis.

Dismantle of the external handle of a door: besides other, it is necessary to cast away a rotary latch (1) and to unscrew bolt TORX (2).

In drawing screw connection (2) window lifterа with glass of a window (1) behind in a box of a forward door is shown.

  1. Remove a support of assembly knots of a door from its basis how it is described above.
  2. Unscrew two bolts TORX on 6 mm.
  3. Remove the lock.

 Councils: In a small series door-locks have been established without a synthetic covering. These locks are dismantled without removal of "a support of assembly knots from a door.

At installation of a new operating bar between the cylinder of the lock and the door lock it is necessary to adjust its length.
