Tractor Coupler Mounting (Kingpin or Fifth Wheel)
Non-Straight Frame – With or Without a Body:
1. Full Angle Mounting – Preferred
In addition to the general installation recommendations listed on the previous
page, the following specific recommendations must be followed:
A. If a folding kingpin is to be installed, the following procedures must be
completed before going to step C:
1. The 40˝ dimension of the kingpin plate must be installed parallel with the
rear axle with the upright kingpin centered between the pickup sides.
2. Check under the floor in the area where the kingpin is to be located to avoid
interference with the differential, drive shaft or frame cross members. The
area should be clear 3˝ below the floor when the springs are fully bottomed.
3. Cut a hole in the truck floor
to receive the folding
kingpin box (see Figure 4).
NOTE: The folding kingpin base is
offset. Cut three sides of the floor and
fold the flap down and out of the way.
B. Initially position the coupler
plate in the box or on the frame in
the desired position (at least 2˝
ahead of the rear axle). If possible,
the coupler plate should be
attached using a full-length
mounting angle (3˝ x 3˝ x 5/16˝
minimum, ASTM A-36) on each
side (see Figure 2).
C. A minimum of four (4) Grade 8, 1/2" diameter (minimum) bolts must be applied
to attach each mounting angle to the frame rail.
D. Proper length tube spacers (3/4˝ I.D. x 1 1/2˝ O.D. recommended) must be used
to shim the distance between the mounting angle and the coupler mounting
plate (minimum of 4 per side).
