Changing the friction lining
It is very easy to exchange the friction pads
j
when they are worn out. Messrs. Winterhoff
offer a corresponding set of spare parts. Please
note the detailed instructions for assembly in the
manufacturer's spare part kit.
Noises
Certain noises can occur during the course
of the drive; these noises, however, have no
inuence on the operative effectiveness of the
tension ball coupler.
Possible causes of these noises can be:
1. a dacromet-coated coupling ball on the
base vehicle.
2. A galvanized or varnished coupling ball on the
base vehicle.
3. A damaged, rusty or dirty coupling ball on the
base vehicle.
4. dirty friction elements
j
on the tension ball
coupler.
5. the towbar or tie rod in the linings of the over-
running equipment are running dry.
Hints
For 1., 2. and 3.:
Sand down the surfaces of the coupling ball and
clean them with a thinning solvent or spirit.
for 4:
Clean the surface of the friction elements with
sandpaper (200-240 grain) and then clean with
petroleum ether or spirit.
for 5:
Use a lubricating nipple to grease the linings.
Pull back the shock absorber and grease the
bare towbar.

Tension ball coupler
Keep the friction linings inside the tension ball
coupler 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.
