in

the

next

It

is

possible

that

you

are

re-

moving

the

tiller

tine

shaft

as

part

of

the

tiller

drive

shaft

removal

procedure.

Regardless

of

why

you

are

removing

the

you

When

have

the

opportunity,

perform

the

following

two

steps.

a.

Put

the

on

an

open

vise

so

that

the

ends

of

the

cover

are

supported.

Tap

out

the

seal

(6)

and

discard

it.

Note:

Do

not

pry

or

tap

directly

on

the

side

Doing

so

using

a

punch

to

drive

the

inward.

Be

careful

not

to

damage

the

inside

of

the

tiller

housing.

Note:

You

only

need

to

remove

this

bearing

cup

if

you

will

using

a

new

right

its

bearing

if

you

intend

to

reuse

them.

Each

bearing

cup

wears

differently

according

to

its

bearing.

Use

a

punch

to

remove

the

bearing

cup

from

the

housing

cover

(only
