NOSE GEAR
The nose gear comprises a steerable nose wheel mounted on a welded steel assembly
with an aluminium wheel yoke and a rubber spring system.
The steel tube is constrained within two Ertalite bushes mounted in an aluminium housing
which is attached to the front of the firewall.
Nose wheel steering is achieved by connecting the rudder pedal assembly to the nose
wheel steering link by push rods. The nosewheel is centred by springs.
A nose wheel speed fairing (wheel spat) is standard equipment.
Disassembly, inspection, repair and reassembly of the nose wheel assembly are
described in separate paragraphs.
The wheel is in two halves which are joined by through-bolts to the wheel hub as shown in
Figure 18. During assembly of the nose wheel, the through-bolts must be tightened
evenly and torqued to the value specified in Table 2.
