Check
clearance of shift dog which
engages
in slot
of clutches, and if found to be greater than .009" [0,229 mm.] clearance, replace the worn parts.
Assemble upper clutch lever assembly in housing
making
sure that the alignment
hole
in the housing
faces toward the engine.
Turn
the upper lever as­
sembly in as far as it
will
go and then back off one

full
turn
until the
hole
in the clutch lever aligns

with
hole
in the housing.
Assemble the lower clutch lever assembly in hous­ ing until faces of clutches contact then back off
not more than one-half
turn
which should bring
the aligning
hole
in the lever in line with the
hole
in
the housing. If the one-half
turn
does
not bring
the alignment
hole
in proper position, it
will
be
necessary to grind off (square with axis not to exceed .015") [0,397 mm.] the face of the lower

clutch;
in other words, backing off not more than
one-half
turn
from face to face contact
gives
the

proper
clearance of .015" to .031"
[0,397-0,794
mm.]

between
the two clutches.
Assemble the unit to the steering
post
in reverse

order
of dismantling and adjust remote control

rods.
After
assembly, if the shift dog catches on the
edge

of the slot in the clutch when moving the lever up

and
down, disconnect the shift rod at the
transmission
end and either lengthen or shorten it
slightly to correct this condition.

Initial
Adjustment —

a.
Should wheel brake units have
been
disassem­ bled for any reason, an initial adjustment
MUST
be made
before
drum installation.

b.
When the brake parts have
been
installed in
their correct position, initially adjust the adjusting
screw assemblies to a point where approximately Y% [9,53 mm.] of threads are
exposed
between
the

star
wheel and star wheel nut.

Note:
Following the initial adjustment and final
assembly, check brake pedal height to ensure

brake
operation. Then drive the car in reverse and

making 10 to 15 brake applications prior
to road testing.
This
action balances the adjust­
ment of the four brake units and raises the brake
pedal.
c. Adjustment may be made manually by remov­ing the access
slot
cover and using a brake adjust­
ing
tool
or screw driver to rotate the star wheel
until
the wheel is in the locked position. To tighten, rotate the star wheel in the clockwise direction.
Then
back off the star wheel at least 15 to 20

notches

d.
To back off the star wheel on the brake, insert
ice pick or thin blade screw driver in adjusting screw
slot
to hold lever away from adjusting screw.

Back
off on adjusting screw until wheel and drum

turn
freely. Replace adjusting
hole
cover.

Caution:
DO NOT attempt to back off on ad­
justing screw without holding adjuster lever away from screw as adjuster
will
be damaged.

DISASSEMBLY
a.
Remove the filler cap and empty all fluid.
b.
Remove the snap ring, push rod assembly, and
the primary and secondary piston assemblies. Air pressure applied in the piston
stop
hole
will
help
facilitate the removal of the secondary piston as­
sembly.
c. The residual check valves are located under
the front and rear fluid
outlet
tube
seats.

d.
The
tube
seats
must be removed with the
self-

tapping screws supplied in the repair kit to permit removal of the check valves. Screw the self-tapping
screws
into
the
tube
seats
and place two screw

driver
tips under the screw head and force the
screw upward as shown in Fig. P-14.
e. Remove the expander in the rear secondary cup, secondary cups, return spring, cup protector,
pri­

mary
cup, and washer from the secondary piston.
f. The primary piston, with the rubber cups in­ stalled, is supplied in the repair kit.

CLEANING
a.
After disassembly, immersion of all metal parts
in
clean brake fluid or a brake system cleaner is
recommended. Use air
hose
to blow out dirt and cleaning solvent from recesses and internal pas­

sages.
When overhauling a hydraulic brake unit,
use all parts furnished in the repair kit. Discard
all
old rubber parts.

b.
After cleaning, place
all"
hydraulic
system parts
on clean paper or in a clean pan.

INSPECTION
Inspect all other parts for damage or
excessive

wear.
Replace any damaged, worn, or chipped
parts.
Inspect hydraulic cylinder bore for
signs
of
scoring, rust, pitting, or etching. Any of
these
will
require
replacement of the hydraulic cylinder. 331
