SERVICE MANUAL
To locate code number on key switch, remove
key switch mounting cap nut and detach key switch from
instrument panel.
The key switch cylinder can be replaced providing the
regular key is used.
REMOVE
To remove key switch cylinder from switch body,
place key in switch cylinder’ and insert a piece of stiff
wire or rod 1.5 mm (1/16") dia. in the small hole behind
cap nut in switch body. Turn key to left (accessory
position) and press the cylinder retainer down with the
wire. The switch cylinder can then be pulled out of
switch body.
INSTALL
To install a new switch cylinder, simply push
cylinder into switch body and turn to right ("ON" position)
until the cylinder retainer snaps into place.
Door lock cylinder replacement is by the
complete assembly. Lock cylinder itself (tumbler unit) is
not removable. If door lock replacement is required, lock
cylinder assemblies should be replaced in pairs.
If a replacement of key switch cylinder is
necessary and the operator wants to use the original key,
the tumblers on the new switch cylinder can be coded
accordingly.
This is accomplished by inserting original key in
new cylinder (cylinder removed from body) and filing off
the tumblers that protrude from cylinder. When making
this change, be sure no burrs are left on tumblers and all
filings are blown out with air. Apply a small quantity of
powdered graphite to tumblers and reinsert cylinder in
key switch body.
IMPORTANT
If keys are lost, switch cylinder must be
drilled out using a 7.9 mm (5/16") drill,
12.7-19 mm (1/2-3/4") deep. This will
permit tumblers to drop out and free
lock.
