critical to insure that the T.V. mechanism moves in the
correct proportion to the throttle opening. The mounting
location for the T.V. cable connector pin will have to be
established on the throttle bellcrank at a radius of 1.094 /
1.125 in. There may a suitable existing hole at the correct
radius on the throttle bellcrank, otherwise you will have to
fabricate an attachment to the bellcrank that will properly
locate the connector pin.
Diagrams of several typical factory installations are shown
for reference (see Fig. 6). Notice the geometric relation-
ship between the T.V. cable bellcrank (attached to the
carburetor or the throttle body) and the mounting bracket.
Several things should be kept in mind during this stage of
the design:
1. The proper location of the T.V. cable mounting bracket
is determined by the angular and radial position of the
T.V. cable connector pin on the throttle bellcrank.
2. Make sure that all of the cables or rods that will be
attached to the throttle bellcrank do not interfere with
each other when the throttle is advanced from idle to
wide open.
3. Mount the T.V. cable adjuster housing so that the locktab
is readily accessible and not blocked by other cables,
rods, brackets or other engine mounted accessories.
STEP 4. Fabricate T.V. cable bracket using 0.090 - 0.125
in. sheet metal (see Fig. 7) for the adjuster housing cut-
out dimensions. If you use the thicker stock a chamfer
will be required on two sides of the cable mounting cutout
to allow the lock tabs to expand properly. The T.V. cable
adjuster requires a pull of about 18 lbs. to ratchet out, so
try to make the mounting bracket as rigid as possible. If
the mounting bracket flexes the T.V. pressure will not be
consistent.
