fabrication is Intended to Conserve
Power Not to Waste 1t.
Much of the power which the pistons
receive from the burning charges Ia
wasted, before it can act usefully at
the rear wheels and these losses are
being intensively studied in the inter
I est of gasoline economy. fabrication of
all moving parts is designed to reduce
these losses to a minimum. but 1t is
being realized that all too often, pre-
calling fabrication methods entails
serious power waste. The viscous,
sticky lubricants of a semi solid nature
frequently used in transmissions and
rear aNles, clingins to rapidly moving
gears and constantly churned and
beaten by them, absorb a great deal of
power in their internal friction just
as molasses candy requires power to
work" it A transmission filled with
sticky grease, is very much like
bread mixed filed with dough and one
can imagine that considerabl power
would be required to turn the bread
mixer and several thousands revolu-
tons per mnute-the speed of the
transmission shafts, These "Churning"
losses increase very rapidly with speed
and contribute material to low fuel
economy at high speeds. Wasted power
manifests itself as heat and transmits
sions filled with thick adhesive greases
become very warm from this cause.
Cars making fuel economy runs always
| use thin oil in their gear boxes and
| rear ends, to reduce power waste and
the proposition is being made. that
gear boxes he designed for forced lub-
| rication, with thin oil. instead of be-
| ing adopted to use heavy lubricant
\ The lesson from all this Ia that the
| transmission and rear end of the ordi-
nary car should be supplied with as
| hud n lubricant as can be used with
| nd ytvit f,ria ont
gear quieting results When a heavy
grease filling is specifically recon-
mended for certain transmission by
| the manufacturer. IT may be best to
FOLLOW, such instructions but when the
use OF a steam cylinder oil or even n
lighter oil is permissible or recon-
mended. heavy grease flling is in,
advisable on all accounts
Clutch Pedal Needs Adjustment
j. 7. u. writes: | have to push the
clutch pedal OF my car hard agsins,
the floor boards. when changing
speeds, or else the gears grind. What
can ! do to improve matters7
Answer: II appears that your clutch
discs have worn sufficiently so that
the pedal. in its engaged position. is
too far forward, the result being that,
before It can be pushed forward far
enough ito fully separate the discs, i,
strikes the floor or comes very near
doing so. The grinding is due TO the
driven discs and the clutch-shaft gears
keeping in motion tsp'nping) when
they should be at rest. because they
are not fully out Of contact with the
driving gears We think that your
clutch pedal can be adjusted on its
shaft SO that II will stald lack further
This will insure full release while yet

1t and the floor board.

Answer Apparently. not enough fuel
