TRUCK FRAME RAIL

The full length of the fifth wheel mounting angle should seat flush on

the truck frame when mounting to prevent flexing of mounting angle

and to give uniform weight distribution along truck frame rail.

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.

Weld as shown in FIGURE 3. Make

5/16˝fillet welds inside and 3/8˝

groove welds on the outside with skip

welds 3˝ long on approximately

8-1/2˝ centers (weld 3˝, skip

5-1/2˝). Weld inside opposite skips

on the outside. ALSO WELD: The

plate to the top of the angle at the

ends of the plate.

5. Attach the slider plate and

mounting angles to the tractor

using recommendations in

“General Recommendations”

and in FIGURE 4.

6. Reassemble the fifth wheel top

plate and bracket sub-assembly to

the slider base plate if they were

removed previously.

Outboard Angle Mounting

(See Figures 5 and 6):

1. If angles are not installed, see “Installation: General Recommendations,” on page 3,

for thickness and material. Use 3˝ minimum horizontal and 3-1/2˝ minimum

vertical leg size. Longer horizontal legs may be required with narrow frame widths.

The recommended length of each mounting plate is the same length as the slide

base mounting plate.

2. In addition to the information given in “Installation: General Recommendations,”

on page 3, follow the recommendations in FIGURE 5 and FIGURE 6. The following

sequence is suggested:

A. Securely position the mounting angles to the tractor frame and attach as shown

in FIGURE 5. Follow the bolting recommendations as shown in FIGURE 4. Angles

must be flush with the top of the truck frame.

B. Locate the slide base and center left to right and front to rear on the mounting

angles. Clamp in place and drill 21/32˝ diameter holes using the mounting

plate as a template if holes are not provided in the angle.

C. Align holes in the slide plate with outboard angle mounting holes and bolt

using Grade 8 fasteners, hardened steel washers and Grade C locknuts, properly

tightened, (see FIGURE 6). Use all mounting holes on the fifth wheel.
