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

Dismantling of the external handle of a door

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

4 – decorative panel;
5 – fixing bolt of TORX ahead.
The arrow showed a spring clip of the managing director of a bar of the disconnecting contact.

The operating lock bar with the following details

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

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

The window regulator is visible from the back party on functional model:

1 – the top directing roller;
2 – the directing window regulator tire;
3 – the support flew down;

4 – window regulator engine.
Shooters – screw connections of a glass/window regulator.

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

The lock of a door hangs only on two screws (1 and 2). But at preliminary works on dismantle of the lock the 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: in addition, it is necessary to cast away a rotary latch (1) and to unscrew a bolt of TORX (2).

In drawing screw connection (2) window regulators 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 as it is described above.
  2. Unscrew two bolts of TORX on 6 mm.
  3. Remove the lock.

 Councils: In a small series door locks were put without synthetic covering. These locks are dismantled without removal of "a support of assembly knots" from a door.

At installation of the new operating bar between the cylinder of the lock and the lock of a door it is necessary to adjust its length. Length can be regulated by moving of the including plug on a hinge detail from the lock of the operating bar back. Then the including plug again moves forward therefore the bar is fixed.
