DESCRIPTION & OPERATION

7.7 LANDING GEAR

The fixed-gear PA-28-161 is equipped with a Cleveland 5.00 x 5 wheel
on the nose gear and a Cleveland 6.00 x 6 wheel on each main gear (Figure
7-1). Cleveland single disc hydraulic brake assemblies are provided on the
main gear. The nose gear has a 5.00 x 5 four-ply tire, while the main wheel
assemblies have 6.00 x 6 four-ply tires. At gross weight, the main gear tires
require a pressure of 24 psi, and the nose gear tire requires a pressure of 30
psi.
A spring device is incorporated in the rudder pedal torque tube assembly
to provide rudder trim. A bungee in the nose gear steering mechanism
reduces steering effort and dampens bumps and shocks during taxiing. By
using the rudder pedals and the brakes, the nose gear is steerable through a
30 degree arc each side of center. Later aircraft have the bungee removed from
the nose gear steering mechanism and are steerable through a 20 degree arc
each side of center. A shimmy dampener is also included in the nose gear.
The three struts are of the air-oil type with the normal static load
extension being 3.25 inches for the nose gear and 4.50 inches for the main
gear.
The brakes are actuated by toe brake pedals which are attached to the
rudder pedals or by a hand lever and master cylinder located below and
behind the center of the instrument sub panel. Hydraulic cylinders are located
above each pedal and adjacent to the hand brake lever. The brake fluid
reservoir is installed on the top left front face of the fire wall. The parking
brake is incorporated in the master cylinder and is actuated by pulling back
on the brake lever and depressing the knob attached to the left side of the
handle. To release the parking brake, pull back on the brake lever to
disengage the catch mechanism and allow the handle to swing forward
(refer to Figure 7-5).
