BELOW.

THESE INSTRUCTIONS REPLACE THE 

“SECONDARY LOCK INSTALLATION”

SECTION IN THE ATTACHED MANUAL.

1.

Pre-install the secondary lock (

10

) in the closed

position in the casting. Do not install spring,
handle, or secondary lock pin yet. Align the lock
pin holes and rotate the secondary lock up
against the adjustment block. Check the location
of the end of the secondary lock in relation to
the swinging lock. It should be 3/16” (0.188”)
±1/16” (0.06”) from point (

A

) on the swinging

lock (

see Figure D

) when the secondary lock is

resting against the adjusting block at point (

B

).

A. If the dimension is less that 1/8” (0.125”):

Mark the area where the secondary lock
made contact with the adjusting block.
Remove the secondary lock, then place a
bead of weld on the adjusting block where
the secondary lock makes contact with the
adjusting block and grind smooth. Do not
weld on the secondary lock. After welding,
recheck as in 

Step 1

, above.

B. If the dimension is more that 1/4” (0.25”):

Mark the area where the secondary lock
makes contact with the adjusting block.
Remove the secondary lock, then grind on
the adjusting block. 

CAUTION:

A small

amount of grinding on the adjusting block
results in a large movement of the secondary
lock. After grinding, recheck, as in 

Step 1

.

C.

After a final check of the dimension, coat the
lock pin hole in the secondary lock (

10

) with

Never-Seez

®

(supplied with kit). 

DO NOT

use

any substitute lubricant.

D.

Install the secondary lock release handle (

9

)

into the casting. Install the secondary lock
(

10

) onto the handle. Install cotter pin (

8

) in

handle and spread cotter pin. Drive the
secondary lock pin (

3

) through the holes in

the casting and the secondary lock and
secure with cotter cotter pin (

2

). Install

grease fitting (

25

) in lock pin so that the

fitting faces the side and will be accessible
from the left side of the tractor.

PROCEDURES FOR INSTALLATION OF SECONDARY LOCK ON MODELS

ORIGINALLY

EQUIPPED WITH SWINGING LOCK AND SECONDARY LOCK AS

SHOWN IN 

FIGURE A

, BELOW.

THESE INSTRUCTIONS REPLACE THE 

“SECONDARY LOCK INSTALLATION”

SECTION IN THE ATTACHED MANUAL.

1.

Coat the lock pin hole in the secondary lock
(

10

) with Never-Seez

®

(supplied with kit). 

DO NOT

use any substitute lubricant.

2.

Install the secondary lock release handle (

9

)

into the casting. Install the secondary lock
(

10

) on to the handle. Install cotter pin (

8

) in

handle and spread cotter pin. Drive the
secondary lock pin (

3

) through the holes in

the casting and secondary lock and secure
with cotter pin (

2

). Install grease fitting (

25

)

in the lock pin so that the fitting faces the
side and will be accessible from the left side of
the tractor.

3.

Move the secondary lock handle to the closed
position. Check the location of the end of the
secondary lock in relation to the swinging
lock. It should be 3/16” (0.188”) ±1/16” (0.06)
from point (

A

) on the swinging lock (

see Figure

B

) when the secondary lock is resting against

the casting at point (

B

).

4.

If the secondary lock is not in the current
position, install a secondary lock adjustment
block (

36

) as shown in 

Figure B

. Move the

adjustment block until proper adjustment is
achieved, then weld the adjustment block in
position, as shown in 

Figure B

. After welding,

check the dimension and for proper operation
of the secondary lock.
