Engine Seat OF Trouble.
The engine is the seat Of the greater
part Of the unnecessary noises that
seem Inevitable in the operation Of the
car. The commonest engine noises are
valve clicks and slaps, both Of which
may be detected by the rhythmical
regularity Of their occurrence.
The reaso for noisy gear operation
In too great clearance between the
valve and Its seat. In the case Of over
head valves too great a clearance be-
tween litter and push rod will cause
the trouble. The remedy Is obviously
the reduction ef-the clearance to the
correct distance and this work should
be done while the engine Is heated.

While the valve system Is the com

engine 1t Is not the sole location where
this trouble may be looked for. The
bearings in most engines are Of soft
metal, which must be kept copfously

out with a knock as the result. The
ordinary remedy for this is to take up
the bearing by removing the SHIN be-
tween the two halves, Or else to trim
the metal on the movable part. Care
must be used in performing this opera
tdon to see that the bearing touches
the shaft all around without being too
light.
Reason for Many Noises.
Transmission noises are not at all
uncommon and generally result from
one Of the shafts being out Of line by
reason Of a worn bearing or a binding
gear. Sometimes the entire transmits
sion is out Of line, 10 that both shafts
are out Of true. Very often a gear
may be broken because the shaft has
been out Of line. The a owner has

help for long, because the entire unit
Is out Of alignment. -

This finishes the major noises, but
