Landing Gear Service - Piper Cherokee Arrow II Pilots Operating Manual

ARROW I1
LANDING GEAR SERVICE
The main landing gear uses Cleveland Aircraft Products wheels and Cleveland single disc
hydraulic brake assemblies. The main wheel tires are 6.00 x 6, four-ply rating, type
Ill
with
tubes. The nose wheel uses a Cleveland Aircraft Products 5.00 wheel with a 5.00 x 5, four-ply
rating, type 111 tire with tube.
Wheels are removed by taking off the hub cap, cotter pin, axle nut, and the two bolts
holding the brake segment in place. Mark tire and wheel for reinstallation; then dismount by
deflating the tire, removing the three through-bolts from the wheel and separating the wheel
halves.
Landing gear oleos on the Cherokee Arrow should be serviced according to the instructions
on the units. The main oleos should be extended under normal static load until 2.0 f .25 inches
of oleo piston tube is exposed, and the nose gear should show 2.75 f .25 inches. To add air to
the oleo struts, attach a strut pump to the valve assembly near the top of the oleo strut housing
and pump the oleo to the desired position. To add oil, jack the aircraft, release the air pressure
in the strut, remove the valve core and add oil through this opening with the strut extended.
After the strut is full, compress it slowly and fully to allow excess air and oil to escape. With the
strut still compressed reinsert the valve stem and pump up the strut as above.
In jacking the aircraft for landing gear or other service, two hydraulic jacks and a tail stand
should be used. At least 250 pounds of ballast should be placed on the base of the tail stand
before the airplane is jacked up. The hydraulic jacks should be placed under the jack points on
the bottom of the wing and the airplane jacked up until the tail skid is at the right height to
attach the tail stand. After the tail stand is attached and the ballast added, jacking may be
continued until the airplane is at'the height desired. There is also a jack point behind the nose
gear actuating cylinder.
The steering arms from the rudder pedals to the nose wheel are adjusted at the rudder
pedals or at the nose wheel by turning the threaded rod end bearings in or out. Adjustment is
normally accomplished at the forward end of the rods and should be done in such a way that
the nose wheel is in line with the fore and aft axis of the plane when the rudder pedals and
rudder are centered. Alignment of the nose wheel can be checked by pushing the airplane back
and forth with the rudder centered to determine that the plane follows a perfectly straight line.
The turning arc of the nose wheel is 30 degrees in either direction and is factory adjusted at
stops on the bottom of the forging. The turning radius of the nose wheel is 13 feet.
The steering
arm
stops should be carefully adjusted so that the nose wheel reaches its full
travel just after the rudder hits its stops. This guarantees that the rudder will be allowed to move
through its full travel.
