PROCEDURES FOR INSTALLATION OF SECONDARY LOCK ON MODELS
ALREADY EQUIPPED WITH ADJUSTMENT BLOCK AS SHOWN IN FIGURE C,
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.

(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

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.
