insert dirt & water
8.
Place housing (15), wearplate
seal
surface down, on a clean work
surface. Apply a small amount of
clean grease to a new dirt and
water seal (20) and press the seal
into the housing seal cavity. The
end of a hammer handle would be
an appropriate tool. Be sure the
seal is not cocked or deformed as
it enters housing seal bore. SEE
FIGURE 38.
place housing
9.
Place housing (15) assembly into
assembly into vise
a soft-jawed vise with coupling
shaft bore down, and clamp the
vise jaws against the edges of the
mounting flange. SEE FIGURE 39.
CAUTION
CAUTION: Clamping on the body
of the housing in the area of
commutator bore could distort the
housing and prevent the assembly
of the commutator (9).
NOTE
NOTE: The assembly of the rotor
set (6) components, if required,
should be done at this time in
order to utilize the housing in the
vise, as a rotor set assembly
"Fixture". SEE "Rotor Set
Component Assembly Procedure"
on page 23.
NOTE
NOTE: The coupling shaft (11)
has a timing mark on the small
(output) end that is radically in line
with two internal spline teeth and
a "commutator drive pin slot"
that transverses the opposite end
of the coupling shaft, SEE FIGURE
40. The "commutator drive pin
slot" indicated by the timing mark
is the only slot of two oil passage
slots across the large end of the
coupling shaft, wide enough to
engage the commutator drive pin
(10) at assembly. This orientation
of the coupling shaft splines aid
drive pin slot is important to
subsequent assembly procedures
that will produce the required
rotor (6A) lobe and commutator
(9) "fixed" radial relationship at
assembly.
NOTE
NOTE: FIGURE 40, shows two
coupling shafts to better illustrate
the relative positioning of the tim-
ing mark, drive pin slot and
internal spline tooth.
