STROKE CHANGES
Remove the plastic gear from the crankshaft by supporting
the edge of the gear and tapping the shaft with a soft
hammer. Be careful not to damage the circlip groove.
The position of the crankpin must be changed in order to
increase the stroke of the cable: Punch the underside of
the crank plate exactly opposite the center of the crankpin.
Use a
3 /
8
" Blair spotweld cutter to cut the pin from the
plate, drilling from the back side at the punch mark. The
pin will be removed, together with a small piece of the
plate.
b\wiper2
Drill a
17
/
64
" hole in the opposite side of the crankplate at
the position indicated in the illustration. Countersink
from the crankpin side just enough that the crankpin will
be flat on the plate after insertion into the hole.
Weld or braze the pin in the new hole from the back.
Clean and deburr the crankshaft.
Install the plastic gear onto the crankshaft, engaging the
tangs of the gear into the crankshaft notches. The
orientation of the plastic cam is dependant on which
footbox your wiper motor is mounted.
Wiper mounted on the passenger’s footbox.
The pin is adjacent to the parking cam
.
b\wipgear
Wiper motor mounted on driver’s footbox.
The pin is opposite the parking cam.
Grease the shaft lightly, install the conical thrust washer,
and insert it into the housing. Install the outer thrust
washer and circlip.
Trim the cable so that it measures 38” from crankpin hole
to the end. Since the wire material is very hard, it must be
done with an abrasive wheel or bolt cutter.
Partially fill the gear housing with grease, and place the
cable into the guide. Some guides are integral; others have
separate plastic liners. Install the connecting rod with its
thrust washers, and the connecting rod circlip.
Install the cover plate with 4 screws.
