6·SPEED TRANSMISSION ASSEMBLY
In order
to
facilitate
reassembly install the
transmission
housing
on
an
engine stand then
proceed as follows:
1.
Assemble the synchromesh
unit
(Item
A,
Fig.
8.11/7)
separately on the work bench, as
follows:
Install on the shaft the 2nd and 5th speed
driven gear (Item 63, Fig.
8.11/11)
with
inner
ring, one synchromesh ring (Item
58)
and the
fixed ring (Item
59)
with
the three
toothed
sectors
fitting
the vanes
of
the previously
fit·
ted rings.
A CAUTION: Arrange the
two
inner rings (Item
56,
Fig.
8.11/8)
and the fixed ring (Item
59)
on
the shaft
with
the
spline
chamfered ends
positioned
as illustrated in Fig.
8.11110).
Install the
sliding
ring (Item
62.
Fig.
8.11/11)
so that the relieved teeth (Item
D)
match
the
splined sectors
of
the fixed ring (Item
59).
NOTE: The assembly
condition
previously
indicated
is the only
which
sets the three
vanes (Item
V)
of the
sliding
ring (Item
62)
symmetrically
with
respect
to
the
toothed
sectors
of
the fixed ring (Item
59).
thus
allow-
ing the
projections
(Item
A)
of
the spring
'
holders (Item
61)
to
fit in
their
respective
locations
(Fig.
8.11112).
Place the flat
springs
(Item
60)
on
their
holders
(Item
61)
as shown in Fig.
8.11/12
then
install
them in place. Install the second syn-
chromesh
element (Item
58,
Fig.
8.1118)
with
the three front
wings
aligned
with
those
of
the
aforementioned
ring, and
finally
install
the 3rd-6th driven gear (Item
57)
complete
with
inside
ring (Item
56).
Try
to
engage the
sliding
collar
by hand in
both
directions,
then
withdraw
the syn-
chromesh
unit
from the shaft.
2.
Reinstall the driven
shaft
(Item
42.
