How can pistons be ioosened when
the oil has run out. causing them to
stick to the walls?
The best way to do the work Is to
discOnncct the rods at the lower ends
and then remove the cylinders with
the pistons and connecting rods. KerO.
sene OF oil should be poured into the
cylinder. and then with a large mon.
key wrench an attempt should he made
to twist the connecting rod. This at
fords means Of turning the piston in
the cylinder. If you cannot loosen the
piston in this way, try heating the pis-
ton and cylinder with a torch and at
the same time twist the rod. Do not
twist too much, for otherwise you will
distort the rods. If the methods sug-
gested are not successful. the best way
appears to be to break the pistons.
Is there any electric system which

them is it safe proposition. The bat

this outlet for current it is very likely
that the generator will suffer.
am having trouble with my motor
overheating. It steams when driven
eight or ten miles. Would too much
oil cause this, as it smokes at the OK.
haust?
The use of too much oil for any
length Of time will cause carbon to de-
posit on the piston and cylinder head
and thus cause the motor to heat. If
misfiring is evident and loss of power,
then treat the motor as one badly car
bombed. However, the heating may
be due to other things besides carbon.
The motor should not be operated with
the spark retarded too far, and the
brakes should not drag. The water
system must, of course, be free from
distractions. If the pistons are poorly
fitted or the rings worn excessively
the oil will work up into the cOmbus-
ton chamber, deposit carbon and cause
heating. Try to do as little intermedi-
ate and low gear work as possible.
What is meant by casshardening?
Casehardening refers to process
of producing a hard coating Of metal
over a piece Of STEEL The process con-
sists of heating the metal and then
lightly sprinkling potassium cyanide
over it while it is hot This causes an
action between the metal and the cy-
anide with the production Of coating
which is very hard. This case or coat
ing has good wearing qualities and
protects the inner metal, which Is soft
err and acts as cushion for the case
Aside from the cyanide mentioned
above, charcoal is used or charcoal
mixed with barium carbonate.

Before giving up the cylinder casting
you should take it to good welder
and have it gone over. Many an ap-
parently hopeless job has been repair
ed by the welding process.
