REMOVAL, DISASSEMBLY AND ASSEMBLY
OF VARIABLE SPEED WINDSHIELD
WIPERS (FIG. 41)
a. Removal
To facilitate assembly of eccentrics at crank
arm link ends, it will be necessary to remove
windshield wiper assembly as a unit whenever
wiper or links are to be serviced.
CAUTION
Before attempting to remove wiper motor for
complete disassembly, wiper should be operated
and shut off by disconnecting it at circuit break-
er behind dash panel control switch, or by turn-
ing off ignition key. Failure to observe this pre-
caution will result in damage to motor switch
and spring parking cam when switch cover is
removed. The motor must not be disassembled
when cranks are in parked position.
Disconnect wiper motor, remove radio (if
so equipped) and remove right-hand fresh air
door. Remove clips that hold links to pivot
cranks. Clips are removed by lifting top tab
and sliding sideways out of engagement with
groove in pivot crank pin. Remove brass spac-
ing washer, slip end of link containing nylon
ball bushing off pivot crank pin, and remove
three windshield wiper bracket to dash panel
retaining nuts. Remove wiper motor bracket
and links as an assembly. A thick rubber gas-
ket is assembled between motor bracket and
dash panel.
b.
Disassembly of Windshield Wiper Links
(Fig. 41)
With motor and link assembly laying on clean
bench, remove clip that holds left-hand link to
crank arm. Remove bevel washers, and care-
fully remove link. The pivot end of link is pro-
vided with a stop to prevent wipers from going
over center and locking.
Remove parking cam and spring release. Re-
move coil spring from around pin by spread-
ing, the springs ends apart, and remove spring
washer.
The right-hand link is disassembled in same
manner, after removing crank arm to crank
lever retaining nut, the brass spacing washers
between link, crank arm and crank lever. After
removing links to clean switch contacts, or re-
place wiper switch or spring cam, disassembly
of wiper motor can be performed as follows:
Remove switch cover and switch plate. Observe
position of cam spring and remove it. Do not
attempt to disassemble switch while wiper is
in parked position. With wiper in this position,
same spring will be under projection at bottom
of switch plate. Application of extreme force
will be required to disassemble it, resulting in
damage to switch and spring.
c. Assembly oi Motor Switch (Fig. 41)
Make sure gear box contains lubricant. Install
parking switch cam spring so that it will en-
gage with nylon drive gear, and the top end
of spring points in same direction as crank
arm. Install motor switch plate and switch
cover.
d. Assembly of Windshield Wiper Link (Fig. 41)
Install spring washer, with concave surface
toward crank arm. Compress ends of crank
pivot coil spring and install on pivot. The
springs are not interchangeable. Install spring
release. The spring releases also are not inter-
changeable. Install parking cam so that it will
index with spring release, and engage ends of
spring between release and parking cam in
openings at point of index.
While parking cam is interchangeable, the
face of cam marked "L" must be away from
link when installed on correct link. The face of
cam marked "R" must be away from link when
installed on correct link. When assembling to
left link, "L" on left crank and on parking cam
should be seen. This positioning also applies to
right link, and "R" on crank and parking cam
should also be seen.
Install spring washer with convex surface
toward cam assembly. Install link arm with
stop projection on link arm toward cam assem-
bly. Install retaining bolt and nut. Assemble
left link and cam assembly to crank lever pfvot
in same manner, locking in place with a clip
instead of retaining bolt. Should windshield
wiper pivot replacement be necessary, perform
following operation, while windshield wiper
assembly is removed. Remove wiper blade. From
under dash, remove two pivot retaining bolts
and Belleville washers. The retaining plate
should drop off when bolts are removed. Re-
move pivot from outside and remove gasket.
