There is a grinding sound in the rear
axle or gears of my car which ! cannot
locate. When the wheel turns halfway
around 1t erinds, and the rest OF tho
way it runs smoothly. Can you ex-
plain this trouble?
1t is a good plan to look for the sim
plest troubles first. If tIe sound is a
rasping or scraping one it is probably
due to dragging brake bands, or the
drums may be out of true. II the
brake bands are dragging loosen them
up slightly. Unless the drums are not
badly out of round 1t will be sufficient
to loosen up the bands, but if this will
not answer the drums should be trued
up In a lathe or else replaced. The
grinding noise may be due to a shaft
that is bent, and 1t is more probable
that an axle shaft instead of a trans
mission shaft would give trouble in
this way. The bending of a shaft will
cause any gear on it to alternately
mesh too loosely and too tightly with
its mating gear. This will cause a
grinding sound. Whether this Is the
trouble can only be determined by in
spection. The Strengthening of the
shaft should be left to some man who
has had experience, and probably you
could not do 1t anyway because Of lack
Of equipment.
Another possibility is that one Of the
roller bearings Is causing the trouble.
One Of the rollers may be broken, al
though this Is not very likely, or the
roller race may be worn out Of round.
would like to replace my five pas
senser body with a seven. Will the ex-
ira %overhang on the rear axle hurt the
motor?
The extra load will not harm the
motor If 1t is not allowed to labor on
high gear. When it is evident that the
car cannot climb a certain hill on high
gear, rather than force it up, a shift
to second should be made. The same
applies when running on second gear
and low gear is required. There is
more danger of hurting the springs or
wearing out the tires. Possibly it
will be necessary to substitute sitter
springs. Unless the tires are amply
large for the weight they are now car
rying, OVERSEES should be put on, at
least on the rear, where the greater
load Is.
Can you tell me of a solution to clean
out a radiator which expeIs water that
is very dark brown in color when
emptying the radiator?
Dark brown water in a radiator Is
due to the suspension in the water of
particles of dirt or rust. There is no
necessity of applying a solution to the
radiator that will dissolve these par
ticles because they can be very easily
removed by flushing the radiator with
large quantities Of water.
have four dry cells located in the
tool box Of my machine which are
used for starting tho motor. They will
last only about three weeks, whereas
one set should last tho whole season.
There is no short circuit, and the con.
nections seem to be all right. Can you
tell mo tho troubIe7
One possible cause is that the cells
you are using are defective, or it may
be that the coil is out of adjustment.
You do not state the type Of coil that
you have, but If 1t is that vibrator de-
sign it is quite possible that your high
battery consumption is due to the trem-
blers being out of adjustment If you
have this type Of coil try cleaning the
contact points Of the tremblers, and
then adjust each trembler until 1t is
working well and produces a good
spark at the plug.
The most likely cause Of your diff
Guilty is that you are using too few dry
cells. It would be much better to con-
meet up five or six in series, as the volt
age generated by four is not enough to
do the work.
Tho slips covering the cushions and
top of my car, which 10 almost a new
one, have become black and have
grease spots On them. Can you tell me
what will clean and remove the spots?
Chloroform will be found quite salts
factory for taking the grease spots out
Of your cushions and top, although it
will not clean out any dust or dirt
that has settled on them. In cleaning
the cushions and top it is we'll to first
brush the dust out thoroughly, then re-
move grease by the use of chlOroform
and finally wash thoroughly with cas-
tile soap and lukewarm water. Case
line has often been suggested as a good
cleaning fluid for such purposes. but
gasoline is a solvent for rubber. and
the material that tops and cushions
are made of often contains a rubber
compound that is injured by the use of
gasoline.
What are the objections to a two
cycle motor?
The objections to the two cycle mo-
tor are that 1t Is difficult to throttle
down. It Is uneconomical and is not as
adaptable to high speeds as the four
cycle.
Will one new patent piston ring in
each cylinder give good results with
the old rinss Of the ordinary type? 10
