Sliding Fifth Wheel Installation - ILS Slider
Prior to proceeding with the installation of the sliding fifth wheel assembly,
carefully review the “General Safety Information” section on page 2.
Inboard Angle Mounting
(See Figures 3 and 4):
1. Angles must be installed on the sliding fifth wheel base plate to facilitate mounting.
See “Installation: General Recommendations,” on page 3, for angle thickness
and material.
2. Use a mounting angle which is at least 2˝ longer than the slide base, 36˝ minimum
length, and 3-1/2˝ minimum vertical leg size. For horizontal leg size, see TABLE 2. The
fifth wheel top plate may be
removed from the base plate for
ease of handling.
3. Position the angles on the slide
plate for the required frame width.
Be sure to keep the plate centered
left to right, and front to rear on
the mounting angles.
4. Weld as shown in FIGURE 3. Outside welds to have a 3/8˝ fillet weld placed either on
or between the tabs, depending on frame width. Inside welds to be 3/8˝ fillet skip
weld alternating with the outside welds so that they are staggered along the angle.
Also weld the fifth wheel base plate to the top of the angle at the ends of the plate
as shown in FIGURE 3.
5. Attach the slider plate and mounting angles to the tractor using recommendations
in “Installation: General Recommendations,” on page 3 and in FIGURE 4.
6. Reassemble the fifth wheel top plate to the slider base plate, if it was
removed previously.
