HOUSING INSTALLATION
RECOMMENDATIONS:
1.
The housing is designed for welded installation into the
upper coupler assembly. The design of the upper coupler
is the responsibility of the installer and must be consistent
with the type and capacity of trailer and design loads for
the upper coupler.
2.
The housing is manufactured from AISI 4130 steel and is
weldable by most processes; a low-hydrogen process is
required. The “square” external shape of the housing will
aid the attachment of required bracing or cross members.
3.
Since the inner portion of the housing is accurately
machined, a welding procedure which alternates
from side to side and which minimizes heat buildup is
recommended to avoid distortion. The threaded holes and
inner surfaces should also be protected from weld spatter
during upper coupler construction.

KINGPIN INSTALLATION
INSTRUCTIONS:
Before starting installation work, verify
that the trailer is securely chocked and
supported to prevent the trailer from moving or falling.
Failure to do so may result in property damage, personal
injury or death.
1.
Clean all foreign material from the housing and the
kingpin. The application of a VERY THIN coating of
rust preventative lubricant to the kingpin prior to
installation will aid subsequent removal.
2.
Insert the kingpin fully into the housing, taking care to
keep it in line to prevent binding. Rotate the kingpin to
align bolt holes and install all bolts until hand tight.
Continue tightening, alternating across the bolt pattern
to insure uniform fit. Tighten all bolts to 180-200 foot
pounds. Recheck torque on all bolts a second time.
3.
After bolts have been properly torqued, wind wire
through holes in bolt heads as shown in
Figure 1
. Feed
the wire through the bolt from the center of the kingpin
out, moving clockwise from bolt to bolt. Wire should be
pulled tight with no slack between bolts. When finished
winding, end of wire should be adequately wound with
the beginning, so as not to come loose.
Lock wire must be installed for a secure
installation. Do not use without lock
wire installed correctly. Failure to correctly install lock wire
may allow bolts to loosen during operation causing kingpin
failure, resulting in separation of the towed vehicle and
subsequent property damage, personal injury or death.
IMPORTANT: Lock wire integrity must be checked every
6 months. Replace if damaged, broken or missing, using
parts from RK-0882 kit and the preceding instructions.
