Steering Wheel Lock - Volvo 164, 1970 Service Manual

Steering wheellock
The engine of the vehicle has been made tamper-
proof by the installation of a steering wheel lock,
which is integrally built with the ignition switch. The
ignition switch has four positions, 0-1-11 - 111. Removing
the ignition key, which can only take place when it is
in position "O", releases a catch and lock pin (A) is
pressed forwards by a spring. When the steering
wheel is turned, so that a slot coincides with the lock
pin, the lock pin enters the sl,ot and locks the steering
column so that the front wheels cannot be turned.
When the ignition key is inserted and switch ed to
position "I", the lock pin is pulled back and this
releases the steering column which is secured in a
withdrawn position. At position "I" the vehicle can be
moved with the ignition switched off.
At position "II" the ignition is connected up and in
position "III" the starter motor can be engaged. The
ignition switch and steering wheel lock can only be
replaced as a single unit.
