The wiper arm is attached to the wiper motor's shaft over a splined
cone. The shaft is made of hardened steel and the wiper arm’s at-
tachment is made of mild die cast material.
When installing, it’s very important to make sure that the splines are
free from metal filings and similar. Also, the nuts shall be tightened
so hard that the splines are pressed into the attachment and act as
a flange. Hold still the wiper arm when installing so that the torque
isn’t transmitted to the motor, which may be damaged (16–20 Nm
tightening torque).
