both worn out.
- Coupling ball is new (diameter of 50), but
shells of friction pads (Fig. 14/ Pos.
l
) of the AKS 2004/AKS 3004 are comple-
tely worn out.
• Determine the diameter of the coupling ball in
order to deduce how much the shells of the
friction pads of the AKS 2004/AKS 3004 are
worn out (diameter of ball may not be less
than 49 mm).
All maintenance work must be carried
out by service stations that have been
authorised by AL-KO!
Replacing the shells for friction pads
• Always replace both of the shells for friction
pads!
• AKS 2004/AKS 3004 must be unhitched.
• Remove the lateral friction pads.
• Pull the rubber cushion up (Fig. 20/Pos.
to remove it.
• Press the safety display (Fig. 20/Pos.
outward and hold it in place, e.g. with a SW
14 spanner (Fig. 20/Pos.
• Remove the cheese head screws (Fig. 20/
l
Pos. ).
• Press the shell of the friction pad (Fig. 20/Pos.
m
) inward and down to pull it out.
• To open the ball-shaped coupling: pull the
clutch grip (Fig. 20/Pos.
position).
• Remove the countersunk screw (Fig. 20/Pos.
n
).
• Use a screwdriver to push the shell of the
friction pad (Fig. 20/Pos.
it out of the ball socket.
A Torx spanner (T25/T30) is required to
unscrew Pos.
The new shells for the friction pads are inserted
in the reverse order.
• Torque up the bolts (Fig. 20/Pos.
to 5 Nm.
• Hang the rubber cushion (Fig. 20/Pos.
over the bottom, then the top of the inset
profiles on the case.
• Attach the lateral friction pads.
