When mounting distributors for tests, first secure the
gear in the test drive mechanism, then push the distribu-
tor housing downward toward the gear to take up any end
play between the gear and the housing.
NOTE:
When testing distributors that have
their lower shaft support bushing located in the
engine block (6 cylinder engines), a special
adapter should be used to insure the shaft will
run true in its housing.
Test the distributor for variation of spark, correct
centrifugal and vacuum advance and condition of contacts.
This test will give valuable information on distributor
condition and indicate parts replacement which may be
necessary. Check the area on the breaker plate just
beneath the contact points. A smudgy line indicates that
oil or crankcase vapors have been present between the
points.
