DR3 wiper motor
With the wiper arms positioned on their serrated
spindles so as to provide the best arc of wipe, the
blades should be parked at the lower edge of the
screen. If the blades fail to park In this position,
adjustments can be made by rotating the knurled
nut which projects from the cable rack outlet-end
of the gearbox.
The knurled nut is to be rotated a little at a time
until the correct parking position Is obtained;
during this adjustment the windscreen is to
be maintained
in
a wet condition.

The switch portion of the gearbox cover Is adjust­
able and can be set to alter the position of the limit
switch with respect to the crank pin and this
determines the position at which the wiper blades
park.

ALIGNING PIP
DR3A wiper motor (Later models)
With the wiper arms positioned on their serrated
spindles so as to provide the best arc of wipe, the
blades should be parked at the lower edge of the
screen. If the blades fail to park In this position,
slacken the four gearbox cover-securing screws
and rotate the domed cover until the setting pip,
formed in the top of the cover, is aligned with the
control groove In the gearbox cover.
The aligning pip must be on that side of the cover
nearest the cable rack outlet in order to obtain
parking with the crosshead away from the worm
gear, or rotated through 180
°
to obtain parking
with the crosshead towards the worm gear.
During this adjustment,
the
windscreen is to
be maintained in a wet condition.
Any attempt to obtain a parked position with the
wiper blades against the screen moulding will
result in noisy operation and a reduced arc of wipe.
Slight adjustments to the parked position of the
wiper blades may be carried out as described
above.
