Distributor Contact Points
•
_,
After every 240 hours of operation, the
distributor contact points should be checked
for wear and correct gap setting. Clean the
points, if necessary, with a few strokes of a
fine sharp file. Never use emery cloth or
sandpaper to clean points, since particles
will embed and cause arcing and rapid burn-
ing of the points. If the points are worn or
pitted exc e ss ive Iv, both points must be re-
placed with new ones. After dressing both
points adjust them for correct gap setting.
Adjustment of contact points can be made
with the distributor rnourited on the engine
as follows:
1. Disconnect the coil-to-distributor
cable at the coil end. Pull the compression
release rod out to the gasoline (starting)
position.
2. Remove the distributor cap, rotor
and seal
(nzust.
71).
Crank the engine
slowly until the breaker arm rests on the
high point of the cam lobe.
3. Loosen the breaker arm locking
screw and turn the eccentric screw until
there is from 0.018 to 0.024 inch gap be-
tween the contact points. Be accurate; use
a feeler gauge.
