cerned Wear and noise, as In the case
Of the gears, can be delayed by careful
fabrication. II the chain runs exposed
to dirt, take care to Intricate it only
on the under side, and when your
motor Is taken down clean the chains
with kerosene and let them soak in
light oil.
"A very annoying squeak may often
be traced to valve stems in sliding in
dry guides. The valve and its stem
are in a particularly undesirable place
as regards lubrication and. although
some oil from the crankcase finds its
way to the stem bushing, you may find
it necessary to supplement this lubri
cation by oiling any friction surface
which can be reached with the oil can.
Leaving the motor and taking up
now the transmission of power, wa

"A loose flywneel connection may
cause a noise similar to that of loose
bearings, but as a rule pounding from
this cause is so severe that 1t obtains
your immediate attention and the ny.
wheels bolts are made tight. II no
privision is made for locking them, and
You experience frequent trouble from
loose bolts, drill a small hole through
nut or bolt and join them together by
threading a wire through each in turn.
Pass on to the clutch. When the
clutch pedal Is thrown out a yoke or
fork presses a collar against the clutch
spring and brings the clutch out OF
engagement. An end thrust ball Is
toll hn q
spring is tensed or compressed. This
bearing Is imperative when the clutch
is in and hence is very likely RESPONSE
BILE for any squeak that exists only
while the clutch pedal is depressed.
Wear of the contact surfaces Of yoke
and collar will cause a rattle, and con-
tinued squeaking is usually caused by
the collar itself. This collar bears upon
the rapidly rotating shaft, and since in
many clutch constructions no provision
Is made for oiling it, it heats up rapid
ly and becomes noisy. If you experi
ence particular difficulty from this
cause, tap the ring and screw in an Oh.
cup to insure proper fabrication.

continual abuse, and noisy transmits

Between the gearcase and the differ

should run well packed in grease, but
because they are inaccessible and
escape your attention they frequently
run dry, wear rapidly and squeak

contain the grease, and If this JACKIE:
does not enclose the Joint 1t should
be replaced or laced tight.
Adjusting DifferentiaI
We come now to the differential.
Any harsh noise or violent hummina
is usually due to poor adjustment of
the main shaft driving pinion and its
mating gear on the differential. The
pinton can sometimes be moved in or
out by turning a nut found at tha
rear Of the transmission case. When
such adjustment is not provided the
same result may sometimes be &C.

ing the rear part Of the housing con,
tanning the main shaft bearing. and
varying the thickness of the shims
between its face and that Of the main
housing. For instance, you desire to
withdraw the pinion one-sixty-fourth
Of an inch. You insert a SHIN Of this
thickness and bolt the housing back
IN place. The noise may be lessened
but not remedied, for in all probable
ity the large differential gear must
also be moved in order to come more
snugly into mesh. Sometimes an ad
1usttng ring is provided behind the
gear, but whatever the device may be,
1t will be readily revealed by inspec.
ton. If your differertial is to run
quietly adjustment must follow wear.

cannot be given here, for such adjust

turers and even with different models
