at

all

times

until

the

nut

is

the

housing.

Do

not

screw.

If

necessary,

back

the

is

properly

seated

if

the

moves

back

and

forth

with

each

turn

of

the

eccentric

shaft.

Tighten

the

hex

nut/bushing

securely

with

a

is

inside

one

of

the

two

detent

cut

into

the

detent

plate.

Then

tighten

the

until

it

can

go

no

further.

Move

the plate

forward

1/16

of

an

inch

and

tighten

the

two

detent-plate

mounting

screws.

You

should

feel

some

lever

play

in

either

the

ENGAGE

or

DISEN-

position.

Removing

a

Rusted

Wheel

If

you

need

to

remove

the

wheel

shaft

and

the

left

wheel

or

both

wheels

are

rusted

to

the

shaft,

fol-

low

these

instructions.

If

only

the

right

wheel

is

rusted

to

the

wheel

shaft,

you

can

still

remove

the

wheel

shaft

by

following

the

instructions

in

Section

5

of

this

manual.

Once

the

wheel

shaft

is

off

you

can

soak

the

rusted

wheel(s)

in

a

penetrating

lubricant

until

you

can

remove

it.

1.

Remove

the

roll

pin

that

holds

the

wheel

to

the

wheel

shaft.

If

the

pin

does

not

come

out

smoothly,

tap

it

out

using

another

pin

as

a

driver.

It

is

important

to

use

a

pin

that

is

the

same

size.

2.

Remove

the

hubcap.

3.

Spray

a

penetrating

lubricant

into

the

wheel

hub

and

let

it

soak.

4.

Raise

the

wheels

off

the

ground

and

leave

them

suspended

in

the

air.

5.

Insert

an

old

wheel

shaft

into

the

hub

until

it

butts

against

the

tiller's

wheel

shaft.

Then,

using

the

old

shaft

as

a

driver,

strike

the

end

of

the

old

shaft

with

a

hammer.

Note:

Only

strike

a

few

times

and

not

very

hard.

You

do

not

want

to

run

the

risk

of

popping

the

snap

ring

out

of

its

groove.

Doing

so

will

make

it

very

difficult

to

remove

the

wheel.

6.

If

you

are

successful,

the

wheel

will

begin

to

vibrate

off

the

wheel

shaft.

7.

If

you

are

not

successful,

you

will

have

to

saw

the

rusted

wheel

off.

Then,

the

wheel

shaft

can

be

removed

by

following

the

instruc-

tions

in

Section

5

of

this

manual.

Note:

Soak

the

rim

of

the

sawed-

off

wheel

in

lubricant

overnight.

Then

use

an

arbor

press

to

remove

the

shaft

from

the

wheel.

Removing

the

Wheel

Shaft

Without

Disassembling

the

Transmission

This

wheel

shaft

removal

and

replacement

method

may

take

some

practice

before

you

are

truly

proficient,

but

it

can

save

you

time

in

removing,

inspecting

and

replacing

a

wheel

shaft

because

you

do

not

have

to

separate

the

transmission

from

the

tiller

or

dis-

assemble

the

transmission.

See

Figure

7-2

as

a

reference

for

the

part

numbers

in

this

section.

Removal

1.

Remove

the

oil

drain

plug

and

drain

the

transmission

gear

oil.

Inspect

the

plug

and

if

it

is

not

damaged,

replace

it

after

the

oil

is

drained.

2.

Remove

both

wheels.

See

the

Owner/Operator

Manual

for

Instructions.

Note:

If

a

wheel

is

rusted

to

the

shaft,

see

"Removing

a

Rusted

Wheel"

in

this

section.
