VALVE
LIFTER-RECONDITION
NOTE:
Because of the important part hydraulic
valve
lifters
play in the operation of an engine and
the
close
tolerances to which
they
are manufac-
tured,
proper handling, and above all, cleanliness,
cannot be
overstressed
when
servicing
these
parts.
New
lifters
are serviced as
individual
units pack-
aged
with
a plastic coating. Leave the coating on
until
ready to check leak-down rate. It is not
nec-
essary
to remove the oil
from
new
lifters
prior
to
checking
leak-down
rate
since special leak-down oil
is
already in new
lifters.
