split
pin
from the swivel axle locking nut. Using a
box spanner and tommy
bar
remove the axle nut
and
ease the flat washer, under the nut, clear
of
the axle
thread.
The front hub can now
be
withdrawn by using
an
extractor.
It
is preferable to use an extractor which
screws into position
on
the hub cap thread,
but
an
ex-
tractor which fits over the wheel studs may also be used.
The hub
is
withdrawn complete with the inner
and
outer
bearings, the collapsible distance piece and the oil seal.
Should the inner bearing remain
on
the swivel axle it can
be
removed by carefully inserting a narrow rod into the
two small holes, in turn, in the back plate each side
of
the
swivel axle and tapping the race lightly.
If
the extrac-
tor is used to remove the race there is a danger
that
the
outer ring
of
the race will be pulled clear
of
the balls and
the bearing will fall apart.
With the hub removed, the outer bearing and the
collapsible distance piece can
be
dismantled by inserting
a drift through the inner bearing
and
gently tapping
the outer bearing clear
of
the hub. The inner bearing
and oil seal can then be removed
by
inserting the drift
from the opposite side
of
the hub.
The removal
of
the brake back plate
is
described
fully in the section on brakes.
Assembling the Front Hubs
When assembling the hub the inner ball bearing race
should first be inserted into the hub with the side
of
the race marked
"thrust"
facing the collapsible distance
piece.
Pack the hub with recommended grease and then in-
sert the collapsible distance piece
so
that the domed
end faces the outer bearing.
Replace the outer bearing so that the
"thrust"
side
faces the distance piece. Use a soft metal drift to replace
both bearings, tapping them gently
on
diametrically
opposite sides
of
the bearing to ensure they move evenly
into their respective housings on the hub. Replace the
hub oil seal over the inner bearing
so
that the hollow
side
of
the seal faces the bearing. Renew the seal
if
it
is
damaged
in
any
way.
The hub can now be replaced on the swivel axle.
This
is
done by using a hollow drift which will bear evenly
on
both the inner and outer races
of
the outer hub
bearing. Gently tap the hub into position until the inner
race bears against the shoulder on the swivel axle.
