Maintenance
Remedial Action
a) Clean the tow ball and friction pads by
lightly rubbing the surface (100-120 grit
emery paper).
b) Lubricate the drawshaft sleeve via the
grease nipples. In addition, push the
gaiter forward and grease (DIN 51 825
KTA 3K) the exposed part of the shaft
(Fig. 30).
c) Visit a specialist workshop to have the
ball holding area checked for damage
and the locking mechanism for function.
If necessary, change the towball.

Servicing and Cleaning
Friction Pad Replacement (please replace
one at a time)
1. Uncouple AKS 2004.
2. Remove protective caps (Fig. 31/Item 1)
with the aid of a small screwdriver.
3. Press worn out pad inwards and remove
(use punch and hammer) (Fig. 31/2)
4. Insert new friction pad from below (after
first re-inserting shim washers if they
were present) and press in as far as it will
go (Fig. 31/Item 4 & Fig. 32).
Checking the efficiency of the front/rear
friction pads
1. Couple the AKS 2004 to the towball but
do not activate the stabiliser.
2. If a green indicator is visible (on the
handle), then the AKS 2004 is in a new
condition or the pads and towball are
within the permissible limits (Fig. 33/Item
2).
3. If only a red indicator is visible (Fig.
34/Item 3), then this may have the
following causes:
a) AKS 2004 is okay but the towball has
reached the lowest limit of 49.61mm
b) AKS 2004 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)
