Dismantling

and reassembling

The

Hardy

Spicer

joint

has four

needle-roller

bearings

retained

on a

centre

spider by

circlips. The

joints

are

packed with

grease

on

assembly

and there

is

no

further

provision

for

lubrication.

Remove

any

enamel

and dirt from

the

circlips

and bearing

races.

Remove the

circlips by

pinching the

ears

together

and

prising

them

out

with

a

screwdriver.

If

a

ring

does

not

slide

readily from

its

groove,

tap

the

end

of the

bearing

race

lightly

to

relieve the

pressure

against

the

bearing.

Hold the

joint

in

one

hand

with the

side of

a

yoke

at

the

top

and

tap

the

radius of the

yoke

lightly with

a copper

hammer.

The

bearing

should begin

to

emerge;

tum)

the

joint

over

and

remove

the

bearing

and needle

rollers

with the

fingers.

If

necessary,

tap

the

bearing

race

from

the

inside

with

a

small-diameter

bar,

taking

care

not to

damage

the

bearing face,

or

grip

the

needle bearing

race

in

a

vice

and

tap

the

yoke clear.

Repeat this

operation

for

the

opposite

bearing.

One

yoke

can now

be

removed.

Rest the

two

exposed

trunnions

on

wood

or

lead

blocks

to protect

their

ground

faces,

and

tap

the

top

lug of the

■ange

yoke

to

remove

the

bearing

race.

Turn

the

yoke

over

and

repeat

the

operation.

When

reassembling,

replace the

cork gaskets

and

gasket

retainers

on

the

spider

journals,

using

a

tubular

drift.

The

spider

journal

shoulders

should be

shellacked

prior

to

■tting

the

retainers

to

ensure

a

good oil seal.

Smear

the

walls of the

races

with

grease

and

assemble the

needle

rollers

to

the bearing

races

and

pack with

grease.

the

bearings

into

position. It

is essential that the

bearing

races

are a

light

drive ■t

in

the

yoke

trunnions.

Repeat this

operation

for

the other

bearings

and

replace the

circlips,

making

sure

that they

are

■rmly

located

in

their

grOoves.

If the

joint

appears

to

lightly

with

a

wooden mallet

to

relieve

any
