First, drairl the water off by opening the pet cock at the bottom of
the radiator; then disconnect the wires at the top of the motor and
also the radiator connection attached to the radiator. Remo ve the
15 cap screws which hold the cylinder head ~n place . Take off the
cylinder head and, with a putty ~ife or screw ~ -driver, scrape from
the cylinder and piston he ads the carbonized matter, being careful
to prevent the specks of carbon from getting · into the cylinders or
bolt ho l es: In re placing the cylinder head gasket tum the motor
over so that No. 1 and No. 4 pistons are at top center; place the gas-
ket in pOsition over the pistons and then put the cylinder head in
pl ace. Be sure and draw the cylind er head bolts down even ly (i. e.,
give each bo lt a few turns at a time); do not tighte n them on one
end before drawine them up at the other.
How ore Spark A 7\ T J1
Plug ,r cleaned? nswer 1 VO.
After i· emov ing the plug from the engine the points may be cleaned
with an o ld toot.h-brush dipped in ga ·soline. However, if!, order to
do the w ork thoroughly, the plug shou ld be taken apart by securing
the lar gt' hexagon steel shell in a vise and l oosening the pack . nut
which holds the porcelain in place. T he carbon depasits can then
be easily re moved from the porcelain and shell with a small knife ..
Care should be exercised not to scrape off t.he glazed surface of the
pOrcelain, otherw i se it will be apt to carbonize quickly. The pOrce-
lain and other parts should finally be washed in gasoline and wiped
dry with a doth.
In assemblin~ the plug care should be taken to see that the pack nut
is not tightened too much so as to crack the parcelain, and the
distance betwten the sparking paints should be ;~" , about the thick-
ness of a . smooth dime.
Di rty plugs usually result from an excess of oil being carried in the
crank case-<>r fr om using oil of paor quality.
