Model 430 / 430A Hinge Assembly
INSTALLATION
the 431 Bracket aligning the bores as much as
possible.
14. At the opposite end that the 439 Flange
resides, insert the 434A Spacer between
434/434B Bushing and the inside surface of the
431 Bracket. Push the spacer in far enough so
the hole is centered with the bracket bore.
15. Slide the 432 Taper pin into the 431 Bracket
bore hole from the opposite end of the 439
Flange (see Figure 5). IF there
are
flats on
each side of the 431 Bracket (older version,
see Figure 6) then make certain the flat on the
taper pin is aligned with the flat edge on the
bracket. If there are
not
Flats on the bracket,
then continue reading.
16. Using a rubber mallet only, tap the taper pin
into the bracket until the head of the taper pin
is flush against the bracket.
17. Place one 321D Washer onto the 321B Bolt
and slide it through the 432 Taper pin. Place
the second 321D washer and 321C Locknut
onto the end of the 321B bolt. Prior to
tightening, check to make sure the 5/16” gap
between the 433 Housing and 431 Bracket
exists (see Figure 1).
18. Torque the 321C Locknut to 60 ft-lbs. Test
the hinge assemblies for desired rotational
stiffness. If a stiffer hinge is desired, tighten
the 321C Locknut in 10-20 ft-lb increments.
DO NOT EXCEED 200 ft-lbs of TORQUE.
19. Tighten the 351 Bolts to 80 ft-lbs of torque.
These bolts compress the 431 Bracket,
clamping both the 439 Flange and 432 Taper
pin. IMPORTANT NOTE: Both 351 Bolts must
be loosened prior to any future adjustment of
the of the 321B Bolt for hinge stiffness. After
adjustment, the 351 Bolts must be retorqued to
80 ft-lbs.
20. An “IMPORTANT WARNINGS!” sticker was
enclosed. This must be attached to the front
end, adjacent to the drawbar eye, visible for the
end user to read.
