Center Gang & Gang Hanger Assembly
At this time it is best to hang the center
gangs and gang hanger tubes before you install
the hitch and hitch strut assembly, Figure 4.
U-bolt the center right and left gang
hanger tubes (1) & (2) to the center brace bar
with 5/8 x 3 x 5 1/2 u-bolts or 5/8 x 3 x 4 1/2 u-
bolts (3), with lock washers and hex nuts. Pin
the preassembled center gangs (4) & (5) to the
gang hanger tubes (1) & (2) with the 1 x 5 1/2
pins (6). Secure with 3/8 x 2 clevis pins & 1/8 x
1 cotter pins. Slide the spring washer (8) &
spring (9) on to the gang spring bolt (7) as
shown and slide it up into the cast swivel on the
gang hanger tubes. Place a 1” flat washer on
the spring bolt and thread the 1” hex nut and 1”
jam nut onto the spring bolt (7). Pin the other
end to the gang with 3/4 x 2 1/2 clevis pins
(10), secure with 1/8 x 1 1/2 cotter pins.
Finally tighten down the nuts on the spring bolt
until the spring has a preload length of 8 3/4”.
On disc models, bolt the center gang
rockshaft (11) to the center brace bar with 1/2 x
4 1/2 hex bolts (12) & 1/2 x 5 1/2 hex bolts (13)
using lock nuts. Attach the short and long
turnbuckles (14) & (15) to the gangs with 1 x 3
3/8 usable pin clevis, machine washers and
3/16 x 2 cotter pins.
