REPLACEMENT
1. If replacement of the points is nec—
essary, this is easily accomplished by dis—
connecting the primary wire from the
points, removing the two point securing
screws, and taking off the points. Install
the new points after thoroughly cleaning
off the contact surfaces with a non—oily
solvent, and adjust the gap. If a breaker
plate assembly is purchased simply dis—
connect the yellow and blue point wires
from the wiring harness and remove the
two breaker plate screws. Install the new
breaker plate and connect the primary
wires. Clean the surfaces of the points
and adjust the gap. Whenever the points
are replaced, the ignition timing will
have to be set.
Breaker plate screws (1), point securing screws (3
and 4), pry point (2) (360)
2. Apply a bit of grease to the breaker
cam lubricating wick. Take care not to
apply too much to avoid fouling the
points.
GAPPING
Gapping is necessary to compensate
for wear of the contact surfaces due to
electrical arcing and for wear of the
breaker point fiber heel. As the heel
wears, the points will open later relative
to the rotation ofthe crankshaft, retarding
the timing.
Points should be filed (if necessary)
and cleaned before gapping.
1. Remove the alternator cover, and
points cover.
2. Using the rotor bolt, turn the engine
over until one set of points is open to
their maximum gap.
3. With the proper feeler gauge, check
the gap. The proper specification for all
Checking point gap
models is 0.3—0.4 mm (0.012—0.016 in.).
The feeler gauge should be a slip fit be—
tween the points if they are correctly
gapped.
4. If adjustment is necessary, loosen
the two screws which secure the points to
the base plate, and use a thin screwdriver
at the pry slot provided to bring the gap
to the proper specification.
NOTE: Loosen the screws just enough
to allow the points to be moved. If too
loose, the points will snap shut instead
of holding the adjustment.
5. Tighten the screws and recheck the
gap. It may change slightly when the
screws are tightened.
6. Repeat the procedure for the other
set of points.
7. Ifit is not possible to gap the points
correctly, the fiber heel is evidently
worn; the set of points should be re—
placed.
LUBRICATION
1. On all models it is necessary to lu—
bricate the cam follower fiber heel and
the pivot point of the contact breaker oc—
