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

DISTRIBUTOR OFF-ENGINE TEST
The distributor's centrifugal and vacuum advance can
be checked in a distributor testing machine or synchro-
scope specially adapted or designed to accommodate this
type distributor. However, since this involves removing
the distributor from the engine, this test may be post-
poned until other system checks have been made. A dwell
reading cannot be obtained on this distributor and it is not
likely that the centrifugal or vacuum advance will be a
cause of trouble.

GENERAL DESCRIPTION
The four-speed synchromesh transmission incorpo-
rates helical gears throughout specially designed to pro-
vide high torque capacity without additional weight, and
gear teeth proportioned to operate at high speeds with
neither excessive heat generation nor excessive fric-
tional losses. Shafts, bearings, high capacity clutches
and other precision parts are held to close limits, pro-
viding proper clearances necessary for durability during
extended heavy usage.
The main drive gear is supported by a heavy-duty ball
bearing at the front end of the transmission case and is
piloted at its front end in an oil impregnated bushing
mounted in the engine crankshaft. The front end of the
mainshaft is piloted in a row of roller bearings set into
the hollow end of the main drive gear and the rear end
is carried by a heavy-duty ball bearing mounted at the
rear end of the transmission case in a retainer casing.
The counter gear is carried on a double row of rollers
at both ends while thrust is taken on thrust washers lo-
cated between the ends of the gear and the thrust bosses
in the case.
The two-piece reverse idler gear is carried on bronze
bushings while thrust is taken on thrust washers located
between the front of the gear and the back of the reverse
idler thrust boss and between the rear of the gear and the
reverse idler shaft boss in the case extension.
Gearshifting is manual through shift control rods to the
transmission cover shifter levers for first through fourth
gears,
and to the reverse lever located in the case ex-
tension. The shifter lever to the rear of the transmis-
sion cover controls first and second gears while the
lever to the front controls third and fourth gears. All
four forward gears are fully synchronized. The trans-
mission may be used as an aid in deceleration by down-
shifting in sequence without double clutching. Reverse is
not synchronized, however, it is a helical gear to insure
quiet operation.
