Maintenance
Coupling ball on base vehicle
The coupling ball should be dimensionally
stable, free of damage, clean and free of grease.
When using dacromet-coated (dull silver anti-
corrosion coating) as well as lacquered coupling
balls, the coating must be removed completely
with sandpaper (200-240 grain) so that it does
not create deposits on the friction lining. The
metal surface of the coupling ball must be
bright. A damaged or dirty coupling ball causes
increased wear of the friction linings; a greasy
one greatly diminishes the stabilization effect.
Thinning solvents or spirit are both suitable for
cleaning.
Tension ball coupler
The interior of the tension ball coupler in the area
of the friction linings should be kept clean and
free of grease (Fig. 5). When the friction linings
are dirty, the surface can be cleaned with 200-
240 grain sandpaper. Then clean with petroleum
ether or spirit. All movable bearings and bolts
are easy to grease. By regular upkeep and
maintenance of your WS 3000, you increase its
overall life span, function and safety.
Changing the friction lining
The front friction lining (1) can be changed in
case of excessive wear. Note the detailed as-
sembly instructions in the manufacturer's set
of spare parts. The rear friction lining has such
a large dimension that it does not have to be
replaced.
