2-4. Apply anti-seize grease to the inner threads of
the Ranch Hitch Adapter base. Thread it clockwise
onto the seated collar, being careful not to cross-
thread the base. Spin the base onto the collar — it
should spin very easily — until the base contacts
the bottom of the pin box. Inspect the base/pin box
contact area and make sure the two touch each
other without any gaps.
2-5. Locate the spanner wrench and "cheater pipe"
(not to exceed 4 ft). Insert spanner wrench into the
punched hole near the bottom of the base. Place
cheater pipe over spanner wrench and tighten to
about 400 ft-lbs torque (this will be about as much
as two men can generate by pulling together on the
end of your cheater pipe). This will finish seating the
threaded collar onto the split collar and ensure a
very strong grip on the king pin.
2-6. Locate the grade 8 bolts, lock washers and
nuts. There are 8 holes drilled in the Ranch Hitch
Adapter Base, but only four need to be used. You
will be responsible to choose which 4 holes will be
used to accept the Grade 8 Bolts. Try to evenly
spread the load as much as possible. Take care to
locate the bolts where they will not interfere with any
gusseting that might be inside the pin box. Drill the
four holes using a 9/16" drill bit. Insert the bolts into
each hole and secure with a lock washer and nut.
Tighten to 55 ft-lbs.
NOTE: Some pin boxes are enclosed and cannot
be accessed for placement of the washers and
nuts. In this case, or in any other application, the
Grade 8 Bolts can be replaced by 4 one-inch tack
welds placed by a certified welder. Drilling and
tapping the pin box metal to accept the grade 8
bolts will not offer sufficient strength and is not
acceptable.
