GOOD WORDS
Alignment of the gear case head holes
with the holes in the reverse coil is very
difficult because once the head
is
in place,
the O-ring prevents the head from turning.
Therefore, before installing the gear case
head, insert a guide pin into opposite corner
holes in the reverse
coil.
Check to be sure
the large O-ring is properly positioned in the
groove in the gear case head.
24- Install the gear case head with the
holes in the head indexing over the pins
protruding from the reverse
coil
holes as
described in the previous paragraph, "Good
Words". Dip the gear case head screws in
Perfect Seal No.4, or equivalent, and then
slide
an O-ring onto the screw. Now, start
the screws through the holes that do not
contain pins. DO NOT tighten the screws at
this
time.
Remove the two pins and start
the other two screws. Tighten the four
screws alternately and evenly. Rotate the
propeller shaft and check to be sure it turns
without excessive drag.
25- Set the wires into the retainer and
secure them in place with the screw and
washer. The washer will hold the screw.
ELECTROMATIC SHIFT 8-71
Bearing head screw with O-ring. A NEW O-ring
should be installed each time the screw is removed
during service work. The recess in the screw head must
be
cleaned
to
allow the O-ring
to
seat properly. If the
ring is left exposed, when the screw is tightened, the
head will cut and destroy the sealing ability
of
the ring.
26- Check to be sure the coils have not
grounded to the lower unit. This can be
accomplished by using an ohmmeter to
check the forward and reverse coil for resis-
tance. The meter should indicate 4.5 to 6.5
ohms resistance.
27- Turn the upper section of the lower
unit upside-down. Apply a heavy coating of
Iii.

coil with the babbitt side of the washer
