the

pilot

diameters

of

the

and

the

propeller

flange

engage

freely.

Butt

the

flange

faces

together.

Without

rotating

either

flange,

check

with

a

feeler

gauge

in

at

least

four

places

as

shown

in

the

illustration.

If

the

maximum

feeler

gauge

that

can

slip

between

the

flange

faces

at

any

point

is

.003",

the

unit

is

properly

aligned.

If

a

thicker

gauge

can

be

inserted

at

any

point,

the

V-drive

must

be

readjusted

until

proper

alignment

is

obtained.

Turn

the

pro-

peller

shaft

flange

1/4

of

a

turn

without

moving

the

gear

shaft

flange.

Try

inserting

the

.003"

feeler

gauge

as

described

above.

The

gap

will

not

change

if

the

propeller

shaft

is

straight.

If

it

increases,

the

shaft

or

flange

is

bent

and

must

be

removed

and

straightened.

Rotate

the

propeller

shaft

flange

in

two

more

1/4

turn

increments

and

repeat

the

procedure.

The

pilot

diameters

must

be

rechecked

to

ensure

that

they

still

engage

freely.

Tighten

the

nuts

on

the

mounting

brackets

and

the

locking

nuts

on

the

adjusting

screws.

Remove

the

set

screws

from

the

brackets

(none

on

RV-IO

or

RV-20),

spot

drill

and

securely

tighten.

Recheck

the

flange

alignment

to

make

sure

the

V-drive

did

not

move

out

of

alignment.

Secure

the

two

flanges

together

with

the

heat

treated

bolts

and

special

In
