AND

FRONT

SUSPENSION

(See

3.11.1

ENTIRENESS

OF

TIRE

The

tire

must

satisfy

several

basic

requirements

to

avoid

inopportune

punctures

or

lowering

of

the

pressure:

•

The

wear

of

the

tread

(1)

must

not

be

excessive.

•

The

tire

must

not

show

abnormal

abrasions

(2).

•

The

tire

(3)

must

not

show

radial

cracks,

which

are

symptoms

of

ageing.

It

is

possible

to

visually

check

all

these

requirements.

The

correct

inflation

pressure

(4)

helps

in

reducing

the

wear

of

the

tire.

Therefore

we

strongly

recommend

checking

it

carefully

and

regularly,

at

least

at

the

beginning

of

each

new

season.

The

correct

inflating

pressure

for

the

nose

tire

is

1,6

‐

1,8

bar.

Please

remember

that

taxiing

on

hard

surfaces

or

asphalt

increases

the

wear

of

tires.

Under

such

conditions,

we

recommend

to

check

the

tire

and

its

pressure

more

often.

3.11.2

FIXING

OF

NOSE

WHEEL

AND

FORK

(See

Fig.

3.11/3)

The

nose

wheel

(5)

and

fork

(6)

are

assembled

through

the

connection

of

the

bolt

pn

M12x160

and

the

fork

pn

093

(for

gyroplanes

with

serial

number

till

16053404)

(or

pn

426)

and

the

spacer

pn

094

(or

pn

427)

and

the

wheel

(5).

Tightening

and

blocking

the

wheel

is

done

with

a

fibrelock

nut

M12.

The

tightening

action

of

the

bolt

M12x160

must

be

adequate,

so

as

to

avoid

compression

of

the

bearings

6201

‐

LU

of

the

wheel

hub

and

allow

complete

freedom

of

wheel

rotation.

At

the

same

time,

the

wheel

must

not

have

any

lateral

play

on

the

fork,

which

could

cause

vibrations

to

the

entire

system.

3.11.3

ENTIRENESS

OF

FORK

The

fatigue

of

the

front

fork

pn

093

(or

pn

426)

can

generate

its

deformation.

Deformation

is

a

symptom

of

hard

landing

or

of

take

‐

off

and

landing

on

very

rough

surfaces.

Periodically

check

the

fork

so

as

to

prevent

excessive

deformation

or

failure

of

the

fork

stem.

3.11.4

CHECK

PROCEDURE

(See

Fig.

3.11/3

‐

3.11/2)

The

fork

check

parameter

consists

in

having

a

90°

angle

between

the

main

structure's

spar

(7),

which

supports

the

bearings

4T

32005X

that

allow

the

fork's

movement,

and

the

plane

created

by

the

fork.
