LR3/Disco 3
The wiper arm is similar in design to the front wiper arms. The arm attachment hole has tapered splines, which mate with
the splines on the wiper spindle. The arm is secured to the wiper motor spindle with a nut. The wiper arm has a pivot
point, close to the spindle attachment. A tension spring is connected to the wiper arm on each side of the pivot point and
applies pressure to maintain the wiper blade in contact with the windscreen.
The wiper blade is attached to the wiper arm with a clip that allows the blade to pivot. The blade comprises a number of
levers and yokes to, which the rubber wiper blade is attached. The levers and yokes ensure that the pressure applied by
the arm tension spring is distributed evenly along the full length of the blade and also allow the blade to adjust to the
curvature and contour of the windscreen.
A plastic cap located on the arm pivot point, covers the spindle attachment nut.
