Fitting

Tyres

Once

you

have'

grasped

the

knack, the job

of

removing

and

refitting

the

low-pressure wired-on tyres mounted

on well-base rims

as

employed

in

the

"Max"

is

sim-

plicity itself. The

secret

of

easy

tyre removal

and

refitting

is

to

press

the

wired

edge

right down into the well

at

one

point with

the

tyre wholly

deflated;

this will loosen

the

point

diametrically

opposite,

so

that

it

can

be

levered

over the

edge

of

the rim. Using

torce

is

very

dangerous

-

the

steel wire

in

the

cover

edge

may

be

rent

in

the

process, which would wreck the tyre

beyond

repair.

Attaching a Sidecar

is

a very simple matter. The

sidecar

bracket

is

fitted to

the

bottom

of

the

frame.

By

means

of

ball connections,

the

"Max"

can

be

quickly

and

conveniently converted

into a

sidecar

machine

and

back into a solo.

To

ensure

easy

steering

and

minimum tyre

wear,

the

combination

must

be

adjusted

for toe-in

and

lean. There-

fore, when fitting a

sidecar

for

the

first time

remember

the

following points: - The

sidecar

wheel should point

in

slightly (1"

to

11fa")

(25-30

mm)

towards

the

front

wheel. Measurements should

be

taken

by

means

of

a

straight

edge

which, when

placed

against

the

sidecar

wheel, must not

be

parallel

with

another

straight

edge

placed

against

the

wheels

of

the

machine, but must

"toe-in"

towards

the

front wheel.

Moreover,

the

machine should

have

a lean

of

5/8"

to

3/4"

(15-20

mm).

In

other

words, with

the

sidecar

empty,

the

machine must

lean

this

amount

outwards,

away

from

the

sidecar. This allows

the

combination

to

run straight

ahead

at

the

most

frequent

cruising

speed

of

aboul

37

m.

p.

h.

on

level

or

slightly

cambered

roads

with the

hands

taken

off

the

handlebars.

If

the

machine pulls. to-

wards

the

sidecar,

increase

the

lean;

if it pulls

away

from

the

sidecar,

reduce it.

The

sidecar

wh'eel

also

should

be

given

some

lean 3/8"

to

5/8"

(10

to

15

mm).

If

the

sidecar

has a floating axle,

this

amount

should

be

measured

with

the

sidecar

loaded.

For

sidecar

work, a 14-tooth chain sprocket should be

fitted

in

place

of

the

16-tooth sprocket.
