(Fig.8.7.11).
Detach
the
retaining

(Fig.8.7.12).
Remove
the
filling

(Fig.8.7.13).
Now
the
motor
base
disc
is
free
to
be
removed;
however,
the
only
way
to
displace
it
is
to
press
it
out
on
a
bearing
press
(Fig.8.7.14)
(Fig.8.7.15).
Dismounting
the
driving
pulley:
take
the
top
screw
out
to
release
the
bushing
(Fig.8.7.16),
push
up
the
bushing
and
washer

(Fig.8.7.17),
push
the
washer
down
to
separate
them,
and
then
remove
the
bushing
(Fig.8.7.18).
Pull

This
will
release
the
washer.
Remove
it
(Fig.8.7.20),
dismount
sealer
cap
(Fig.8.7.21).
Now,
dismount
the

do
not
use
excessive
force
(Fig.8.7.22)
(Fig.8.7.23).
Push
the
sealer

sealant
and
center
the
holes
to
mount
the
pulley.
Change
the
two
other
pulleys
as
earlier
described.
While
the
motor
base
is
dismounted,
roller

can
also
be
changed
easily.
Unscrew
the

MOUNTING
THE
BELT
The
proper
orientation
of
the
belt
is
shown
in
Fig.8.8.11.
The
belt
can
be
installed
when
the
tensioner
is
fully
loosened.
This
can
be
done
by
loosening
nuts
(2)
and
(3).
Unscrew
the
nut
(4)
and
removing
bushing
(5)
from
hole
D
in
the
tensioner
(1).
This
will
allow
the
tensioner
to
move
freely.
The
belt
should
be
installed
as
shown
in
Figs.8.8.1
‐
4,
starting
around
the
central
pulley
and
weaving
outward
until
all
units
are
connected.
Ensure
that
the
belt
is
in
the
correct
orientation,
and
that
the
grooves
of
the
belts/pulleys
line
up
at
each
location.
Position
the
tensioner
such
that
the
bushing
(5)
can
be
reinserted
into
the
hole
D.
(The
bushing
can
be
pressed
by
screwing
screw
(4))
(Fig.8.8.4)
Tighten
the
nuts
(2)
(Fig.
8.8.5)
on
the
sectors
and
then
loosen
by
a
half
revolution.
This
will
allow
the
tensioner
to
turn
with
minimal
force.
Fasten
the
bolt
(Fig.
8.8.7)
in
order
to
achieve
the
right
Tension
and
then
tighten
the
center
nut
of
the
tensioner
(Fig.
8.8.6).
