2. Remove the quadrant and lubricate the spindle
with
Ragosine
204G
or equivalent grease. Refit the
quadrant and
finally tighten the
4
in.
U.N.F. nut.
3. Do not overtighten the nut, since the bearing
boss tends to spread slightly and a tight bearing may
be formed.
4.
Fit the rocking arm assembly, then check to
ensure that the roller lines up correctly with the
quadrant detent form.
5.
Remove the rocking
arm
and hook the tension
spring onto the anchor pin roller on the underside of
the quadrant and onto the spring anchor on the
underside of the
rocking arm.
This operation is made easier by rotating the
quadrant anti-clockwise beyond its normal travel, so
that the spring is not under tension. Rotate the
quadrant clockwise whilst holding the
rocking arm
clear, then allow the roller to locate on the detent
forms. Fit the spring on the top side of the quadrant
and
rocking arm.
Note Do not fit the retaining clip to the rocking
arm at this stage. (They are difficult to
remove, should the need arise).
6. Move the quadrant to
a
mid-way position and
fit the phosphor-bronze contact.
This contact is
assembled between two insulating strips which are
located by two insulating dowels. This sandwich
assembly is then secured to the quadrant by two
screws and washers.
Important Extreme caution must be taken with
the moving contact, so that it is not
bent or damaged
in
any way.
7.
Before fitting the selector lever assembly
carry
out the following checks.
Check that the clevis pin
will
slide through both the
fork end on the lever and the holes
in
the mounting
bosses on the quadrant, then check that the fork end
will
slide between these bosses.
8.
Lightly smear Ragosine 204G or equivalent
grease on the outside of the fork end, the inside of the
bosses, the clevis pin and the clevis pin holes, then
locate the fork end in the bosses by the clevis pin and
fit the spring inside the fork end and over the clevis
pin. Push home the pin and fit the
circlip. Check that
the lever
will
return easily under the load of the spring.
9.
Secure the gate assembly to the underside of the
base by means of the two hexagon-headed 3 B.A.
screws.
Check that, when the position of the lever is con-
trolled by the
detents, it lines up with the profile of
the gate liner and that the extreme positions of the
lever are not limited by the gate.
10. Fit the insulating plate complete with the feed
and supply contacts fitted to it.
When the unit is screwed down by the three screws,
check that the inside leg of the moving contact is
pressing onto the supply contact and that at the
extremities of its travel the hemispherical head is still
making good contact with the supply contact.
11. Each selection should then be ma& in turn,
checking that the outside leg on the moving contact
lines up correctly with each of the feed contacts.
12. Mount this assembly on the two bosses on the
base by means of the two screws and shake-proof
washers.
13. Fit the blue filter with its flattened end in front
of the bulb and behind the bracket mounting screw
heads. Bend the radiused top end over the bulb and
check that it follows the contours of the support
bracket.
14.
Hold the filter in this position by means of a
0.025 in. (0'64
mu.)
feeler gauge held from the front
of the unit, fit the indicator scale over the support
bracket and secure it with two self-tapping screws. The
scale should drop onto the bracket and its lip must
not be forced down.
15. Feed the pointer under the indicator
scaIe, then
with '3 range' selected use a thin-blade 'Phillips' head
screwdriver, to feed the single
5
B.A. screw through
the pointer leg and screw it into the quadrant boss.
Care should
be
takeh not to scratch either the pointer
or
the indicator scale.
16.
Each selection should then be made and the
alignment of the pointer checked.
17. Fit the
micro-switch(es) onto the two bosses on
the rear
face
of
the base assembly. Fit the operating
arm
onto the spindle of the quadrant. On a
car
not
fitted
with
refrigeration set the operating
arm
so that
the single micro-switch is depressed when the selection
is
'R'.
On a
car
fitted
with
refrigeration the two micro-
switches require setting so that the fast-idle micro-
switch is depressed just as the selector is engaging
'N'.
Check that the 'R' micro-switch is operated satis-
factorily.
Note On left-hand drive cars with refrigeration
the fast-idle cam is engaged in both N
and P positions.
18.
Fit the. retaining clip to the rocking arm pivot.
19. Lightly smear
Ragosine 204G or equivalent
grease on the quadrant
detents, then operate the
switch several times to ensure that the
Ragosine is
spread evenly.
