5. lnsert the key in
the shoftwith its bevelled
end into the runout of the keywoy, smeor
the
hub neck with oil so
thot it does not
drog in
the seoling ring, ond fit the hub with the broke
drum in position.
Moke sure thot the key did
not move further olong the shoft (its
lifted end
in the keywoy would couse the hub to burst)
ond tighten
lightly the nut. Since o high
torque
is required
for finol tightening of the nut, put
off the tightening ond locking of the nut till
ofter instollotion in the cor. Then
tighten the
nut with full torque (see
Chopter 1.8),
top on
the hub to relieve
the possive
stress of the
toper, retighten to the specified torque, ond
lock the nut with o cotter pin.

Repair of Window Regulator Defects
lf the windows are difficult to wind up and
down (the
maximum torque applied on the
spindle of the window regulator with the glass
installed in the doors exceeds 2.5 Nm) (1.77
tt
lbs), it is recommended that the following steps
are taken as regards both the front
and rear doors:
1. Disconnect the regulator driving plate
from
the window glass
channel. Push the glass
upward
and try the relieved regulator by turning the
regulator crank. lf the regulator does not work
smoothly (jamming,
rattling) or if
a torque higher
than O.7 Nm/(O.495 ft lbs) in front and 1.1
Nm/(0.78 ft lbs) in the rear is required for its
operation, replace the whole regulator with a new
one working satisfactorily.
2. Adjust the centre pillar position
in the door
using the jig
as per
drawing No. A1-1 5417-S.
Loosen the top screw of the centre pillar
and
retighten it while pressing
the centre pillar
against the window glass
wound up to its upper-
most position.
Loosen the bottom screw of the
centre pillar
and retighten it while pressing
the
centre pillar
against the
window glass. 5417

3. When bolting together the regulator driving
plate with the window glass
channel make sure
that the holes in these two parts
coincide along
the whole length of the channel. lf it is not so,
move the
channel into a satisfactory position.
4. lf the regulator is
not lubricated, lubricate the
regulator cable in the
tubing with grease
and
apply oil to the regulator
crank spindle.
