which is quick, efficient and cheap.
If carbon Is removed 1t is suE-
gested that the valves be ground.
and, while this work may be done by
the owner withsut much trouble. II
he is the possessor of a valve spring
litter and grinder, the shops usually
charge but 81 to SIS for the work.
, However. this may mean much to
some owners. Valve grinding may
be necessary in other motors also.
! If the compression in the cylinders
varies, grinding may be necessary,
yet the valves should not be sus-
pected unless it is known that the
| piston and rings are not loose and
there are no compression losses
through cylinder leaks.
II is rather hard to tell whether
there is leakage past the piston with
out actually fitting the piston and
rings in the cylinder. Testing for
leaks is an easy matter. Get an oil
can, and, while the motor is running.
force "A little oil around the base of
the cylinder plugs, spark plugs, also
at the inlet manifold connection, to
the cylinder, and other joints. If
small bubbles appear when the en-
gine is running there is n leak.
Sometimes one can tell an inlet mani
fold leak by feeling with the hand.
If the cylinder plugs leak, the Plugs
should be removed. the threads
cleaned, some paste, stove backing or
graphite lightly spread over them. II
the motor has a removable cylinder
head and it leaks, new gasket is
needed. The gasket should be lightly
covered with shellac before being re-
placed. Do not use too much shellac |
for the excess may get into the water
jacket or cylinder Also in replacing |
the cylinder head be sure to tighten
the nuts properly. First tighten one
nut slightly then take another on the !
opposite side. and so on. II the nuts
on one side are tightly drawn and then |
those on the other side. the head may |
be sprung and leaks result. Be sure |
the face of the cylinder head is per-
fectly clean and also the gasket. Clean !
every part with cloth before replac-
ing.
After the leaks have been stopped,
tighten all nuts and bolts on the
motor. Tighten the L is holding the
timing gear case cover, tighten the
motor holding down bolts, the nuts
holding the cylinders down, and all
parts that can be frightened with
ing. get n new one, for the nut may
become loose in a day or so. Tighten
the nuts holding down the push rod
guides, or the nut holding the clamp
which holds the guide in place. Most
owners are familiar with the parts of
the motor which require tightening
after use, but it is best to go over
|
from loosening later on in the season.
After tightening these parts, pro-
ceed to the various systems. The
water system may not require much
attention. To be safe. drain the sys-
tenn and refill it with saturated solu-
tion OF washing soda in boiling hot
water. This will have a tendency to
remove deposits. Allow the solution
to remain in the system for a few
minutes. and. II possible, operate the
motor for few minutes while the
solution is in. Then drain and refill
the system with clear water. Do this
flushing twice to be sure all soda solu-
ton has been removed.
Examine the connections to the
radiator, especially those made of rub
ber. Remove the rubber ones and ex-
anime the interior. Sometimes the
rubber disintegrates on the interior
and clogs the system. If this condi-
tion exists. get new hose. for it does
not pay to try to repair the old hose.
With clear water in the system oper-
ate the motor and look over every
for leaks New packing
may be needed in the pump nut. If the
motor is syphonically cooled. there is
no pump, of course. But above all,
stop the leaks. In repacking the pump
nut, use asbestos rope graphited. The
rope may be bought in the supply
store. Rub a little graphite into it .
Finish up the water system
by examining the radiator for leaks 5
and tightening the holding down nuts.
DO not attempt to repair radiator {
