GENERAL MAINTENANCE
This section
of the
Cherokee
Handbook
contains
information
which
pertains
to
minor maintenance
of
the
airplane.
For further
maintenance assistance refer
to the
Service Manual for this
airplane.
Any
complex repairs
or
modification
should
be
accomplished
by
a
Piper Certified Service Center
or

LANDING GEAR SERVICE
The main
wheels
are Cleveland Aircraft Products,
Modelf
40-86,
with
Cleveland
single disk hydraulic brake
assemblies,
ModelA30-55.
The
nose wheel
is a Cleveland Aircraft Products, Model
40-76B.
All
wheels
use a
6.00
x
6, four
ply
rating,
Type III
tire with tube.
Main
wheels are easily removed
by
taking
off
the
hub cap, axle nut,
and the two
bolts
holding the
brake
segment
in place,
after which the
wheel
slips easily
from
the axle.
Tires are
demounted
from
the
wheels
by deflating
the
tire,
removing the three
through-bolts,
and
separating
the wheel
halves.
Landing
gear
oleo
struts should
be
checked
for proper
strut
exposures
and
fluid
leaks. The
required
extensions for the strut when
under normal
static
load
(empty
weight
of airplane
plus
full
fuel and
oil)
is
3.25
inches for
the
nose
gear
and
4.50
inches f'or
the
main
gear.
Should the
strut exposure
be below
that
required, it
should
be
determined
whether
air
or oil
is
required
by first
raising
the
airplane on
jacks.
Depress
the valve
core to allow air to
escape
from
the
strut
housing
chamber.
Remove the
filler plug
and
slowly
raise
the strut to
full
compression.
If
the
strut has sufficient
fluid
it will
be
visible
up
to
the
bottom
of
the
filler plug hole
and
will
then only require
proper
inflation.
