DESCRIPTION & OPERATION P A-28-161, WARRIOR II
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 ha.ve 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
lo~ated
above each pedal and adjacent to the hand brake lever. The brake
.fluld 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).
