Condenser - Hudson 1953 Jet Mechanical Procedure Manual

the stationary contact plate, then turning
eccentric adjusting screw (D) to move the
contact point. Tighten clamp screw when
correct gap is secured.

to secure correct alignment.
BREAKER ARM SPRING TENSION
1. Hook a spring scale to the breaker arm at the
contact and pull at right angles to the contact
surfaces. Tension should be 17 to 20 ounces
just as the points open.
2. Adjust spring tension by loosening screw
attaching breaker arm spring to plate and
move end of spring in or out of clip as
necessary.

CONDENSER

1. Inspect condenser lead to see that it is not
frayed or broken and is connected securely to
breaker arm clip. Condenser mounting screw
must make tight ground to breaker plate.
Ground wire from breaker plate to subplate
must be securely connected.
Check condenser with suitable equipment and
if capacity is not within range of .20 to .25 MFD,
replace with new part.

DISTRIBUTOR DWELL TEST
Check distributor cam angle or dwell on a distribu-
tor tester to determine the cam angle or degrees of
dwell of the distributor point. This should be 39 de-
grees with distributor contact point set at .020".
If the dwell angle is too great, the contact point gap
is set too close. If the dwell angle is too small, the
contact gap is too wide. An erratic reading of the
Dwell Meter will indicate faulty contact, a faulty
breaker plate, a worn distributor shaft and bearings. A
change of dwell angle when accelerating or deaccel-
erating, the engine will indicate a faulty breaker plate,
bearing or support plate.
VACUUM ADVANCE ADJUSTMENT
Vacuum should be checked on a distributor tester
that has a controlled source of vacuum and a vacuum
gauge
.
If the vacuum advance range does n ot conform
with specifications, it may be varied by inserting or
removing washers under the sp r in g in the vacuum
chamber. Carefully check for leaky diaphragm and
sticking linkage.
AUTOMATIC ADVANCE
Place distributor on tester and check the advance
curve R.P.M.'s against the degree of advance.
If the degree of advance is more than specifications
call for at the same R.P.M., it indicates that the gover-
nor spring tension is too weak and the advance is too
rapid.
If the degree of advance is less than specifications,
call for at the same R.P.M., the spring tension is too
stiff and the advance is too slow.
In most cases, the tension of the spring may be
increased or decreased by bending the brackets on the
weight plates to which the springs are attached, in
order to make the springs conform to specifications.
Check the advance both up and down the speed
range so that the sluggish action of the governor will
be indicated and may be corrected by cleaning and
lubrication.
NOTE: Every 2,000 miles, lubricate contact arm
pivot, wick top of shaft, cam lobes and 3 to 5 drops
of medium engine oil at oiler.
