1. Uncouple the AKS 3004 stabiliser.
2. Remove protective caps (see diagram below

3. Press worn out pad inwards and remove
(use punch and hammer) (see diagram

Checking the efficiency of the
front/rear friction pads
1. Couple the AKS 3004 stabiliser to the
towball but do not activate the stabiliser.
2. If a green indicator is visible (on the handle),
then the AKS 3004 is in a new condition
or the pads and towball are within the
permissible limits (Fig 1 - Item 2).
3. If only a red indicator is visible (Fig 2 - Item
3), then this may have the following causes:
a. AKS 3004 is okay but the towball has
reached the lowest limit of 49.61mm.
b. AKS 3004 stabiliser shows signs of wear.
c. Towball is in a new condition (50mm) but
the front/ rear friction pads show a high
degree of wear.
Establish the diameter of the towball so that
conclusions may be drawn as to the wear of
the friction pads (ball diameter must not be
less than 49.61mm).
Friction pad replacement (front/rear)
1. Uncouple the AKS 3004 stabiliser.
2. Remove the soft dock (pull up & off), (Fig
5 - Item 1).
3. Press the safety indicator outwards and
secure with SW14 hex. spanner (not
included), (Fig 5 - Item 2).
4. Remove cheese-head screw (Fig 5 - Item 3
& Fig 18), using special torx tool.
5. Press friction lining recess (Fig 5 - Item 4)
inwards and pull down and out.
6. Open coupling handle (Fig 5 - Item 5).
7. Remove countersunk head cap screw using
special torx tool (Fig 5 - Item 6 & Fig 4).
8. Press friction pad inwards with a screwdriver
and remove.
9. Fit new friction pads in reverse. Tighten
screws to 5Nm (Fig 5 Items 3&6)
10. Replace rubber soft dock, insert top
section then bottom.
