Engine Oil

For
maximum
engine
protection under all driving conditions encountered during the recommended

oil
change intervals, it is necessary to use only

"MS"
certified
sequence-tested
oils. The term
"MS"
must appear on the oil container singly or

in
conjunction with other designations. "MS" des­
ignated oils are heavy-duty detergent oils that are
formulated to withstand all service conditions in
modern powerplants. Engine oils designated only
as
"ML"
and/or
"MM"
are not recommended and should not be used except in an emergency when

"MS"
oil is not available. Certified
sequence-tested

engine
oils are described on their containers by

such
phrases as:
meets,
exceeds,
excels, or has
proven superior in the
test
requirements,
test
sequences, MS Service
tests,
standards, and service

requirements,
of automotive manufacturers, auto­
makers,
or car manufacturers for MS service or
Service
MS.
It
may be necessary to change
engine
oil more
frequently than normally recommended, depending upon the type and quality of oil used, the severity
of operation conditions, if the
engine
is used for
short
periods in cold weather, or if the
engine
is allowed to idle for excessive periods.

Always
drain
the crankcase while the
engine
is hot since
dirt
and contaminants are then more
likely
to be held in suspension and therefore
will

drain
out more completely.
Drain
the crankcase as follows:

a.
Position the
drain
receptacle under the
drain

plug.

b.
Remove the
drain
plug using the correct size

wrench.
Be careful of hot oil.
c.
Carefully
clean the
drain
plug. Inspect and

replace
the gasket, if deteriorated.
d.
When the oil has drained, replace and tighten
the crankcase
drain
plug. 12

Wiper Troubleshooting on Bench

Using
ammeter, capable of reading at least 30
amperes, check
feed
wire circuit for open circuit.

a.
If wiper is inoperative, connect wiper to operate
in
low speed and observe current draw. If the read­
ing is zero amp., check for
loose
solder connection
at wiper terminal or
loose
splice joints. If reading is
1
to 1.5 amp., check for open armature, sticking
brushes, or
loose
splice joint. If reading is 11 amp.,
check for broken gear seized shaft or
some
other
condition that
will
stall the wiper.
b. If wiper
will
not shut off, this condition may
exist if wiper has one or both speeds. If wiper has both speeds, check for
park
switch contacts not
opening or internal wiper motor lead that connects to wiper terminal being grounded. If wiper has low
speed only, check for internal wiper motor lead that connects to wiper terminal being grounded. If

wiper
has high speed only, check for
internal
wiper motor lead that connects to wiper terminal being
open.

c.
If wiper
crank
arm
does
not return to
park

position when wiper is turned off, check for dirty, bent to broken
park
switch contacts.

d.
If wiper operates erratically, check for sticky
brushes or
loose
splice joints.
e. If the wiper
will
not shut off, or wiper
crank
arm
fails to
stop
in
park
position when jumper wire is
removed from terminal, check that
park
switch contacts are opening. Also check for ground in in­

ternal
motor lead that connects to terminal.
f-
Remove fastening screws, cover plate assembly

and
gasket.
g. Remove parking plate and gear assembly.

h.
Remove parking brushes, spring and bowed
washer from gear assembly.

i.
Remove the two through
bolts
and mounting

bracket.

j.
Remove the magnet housing, armature and end cap as an assembly.

k.
Tap end of armature shaft to
loosen
end cap
assembly and remove cap from armature shaft. Be
careful
not to
lose
thrust disc, which is in end cap
bearing bore.

I.
Remove armature from magnet housing.
Care

should be taken to protect armature shaft bearing

journals.

m.
Remove brushes and brush spring from brush
holders.

H-147.
Cleaning
of
Two-Speed
Wiper
Motor

a.
Clean
magnet housing and
armature
with a cloth dampened in cleaning solvent.

b.
The following bearing equipped parts should

not
be immersed in cleaning fluid: 1. Cover plate assembly.
2.
Gear
housing assembly.

3.
End cap assembly.

The
metal surfaces of
these
assemblies should be cleaned with a brush dipped in cleaning solvent,

making
certain that cleaning fluid
does
not contact bearings.

c.
Clean
remaining parts with a brush and cleaning
solvent.

H-148.
Reassembly
of
Two-Speed
Wiper
Motor

Refer
to Fig. H-67.
To
reassemble motor, reverse the
steps
given in

Par.
H-146.
When
reassembling motor, fingers must be clean
when handling brushes. Hold brushes in the holders by applying paper clips to brush shunts. Apply a
light film of lubricant to armature shaft ends,
armature
worm gear and gear assembly shaft ends.
Remove paper clips after assembling armature to gear housing. Align marks on magnet housing and
gear housing. Armature end play should be .002 -
.010".

Be
sure to operate wiper to
park
position prior to installing drive arm.
