8.16 NOSE LEG HOUSING
8.16.1 DESCRIPTION
The nose leg housing is a structure bolted on to the lower, middle of the firewall. The nose leg tube
runs in Ertalyte bushes which are bonded into this housing.
Some models use a housing moulded from fiberglass while others are fabricated from bolted
aluminium.
8.16.2 REMOVAL
Before removing the housing the nose leg steering mechanism must be disconnected (Section 8.12)
and the nose leg removed (Section 8.13).
To remove, remove the bolts holding the housing to the firewall.
If required, the aluminium housing can be disassembled by removing the assembly cap screws.
Note that strong thread retaining compound is used on the cap screws holding the housing together.
To remove it may be necessary to heat the part to about 80°C using a heat gun. Take care not to
break screws.
8.16.3 INSPECTION & REPAIR
Before removing nose leg assembly, assess end float and radial wear in the nose leg bushes. If
necessary the bushes may be replaced as detailed in Section 8.13.5.
Visually inspect fiberglass housing: check for whitening, cracks or tears.
Visually inspect the flock bead of all housings: check for cracking and other damage.
Inspect hardware and metallic parts for wear, damage or corrosion.
