control arm
at
this time.

Slowly pull the transmission from the housing
being very careful not to damage the gear
selection cable. Once clear of the housing, rotate
the
assembly until the cable can be safely
removed.
Transmission Disassembly
Most
repairs to this 'Series
2”
transmission can
be
accomplished without removing the pivot arm
assembly from the output shaft. Only
if
components on
the output
shaft
require replacement will pivot arm
removal
be
necessary.
1.
Remove the six flanged head self-tapping
screws securing the transmission cover to the
transmission case and remove the cover. See
Figure
65.

2.
Before disassembling further, check for proper
operation of the input system, the gear reduction
system and gear selection system.
For
more
information on this, see Transmission
Oper-
ation, page

3.
Removal
of
the
input
shaft and pulley assembly
can
be
difficult because the
input
pinion will have
a
tendency to turn
as
the pulley nut is loosened.
Address this situation by using an impact wrench
or
by
removing the
20
and
25
tooth gears from
the intermediate shaft and then putting the
intermediate shaft assembly back onto the
transmission. The hexagonal intermediate shaft
can then be held with a
7/16'
end wrench while
the pulley
nut
is
loosened.
NOTE:
Using a cut-away transmission cover to
hold the intermediate shaft
in
place may facilitate
pulley
nut
removal.
See
Figure
66.
4.
Remove the intermediate shaft from the
transmission and clean.
Inspect
all gears
for
cracks and/or broken teeth. Inspect the
bushings
for
excessive wear. Replace
any
parts
necessary.
Be careful
not
to lose
the
two
spacers
that
fit
between the bevel gear
and
the bushing.
