Fig. 10 shows the mounting with reinforced and non-
reinforced frame rail. (Section A-A. ) Where the mounting is
made on a reinforced rail, an additional 4 x 3-1/2" angle is
utilized as a spacer. (A-A reinforced.)
The illustration, Fig. 10, represents a typical installation.
Wheel base or fifth wheel location requirements may dictate
some modification or deviation from that shown.
Where the fifth wheel is to be in a raised position, the
mounting details shown in Fig. 11 are to be followed.
With reference to Fig. 11, it will be noted that the support
plates or spacers are fabricated to minimize weight and
assure sufficient fifth wheel support. Note also that these
fabricated sections are extended well forward of the rear
spring front brackets. Here again, welding applied to these
parts should be performed off the vehicle to avoid heating the
frame rail. When welding the spacer or support plate, apply
short runs of weld alternately on each side of the plate as
shown in View D. This procedure will minimize warpage of
the plate during welding.
Fig. 11 shows details of the mounting with reinforced and
non-reinforced frame rail. (Sections A-A and B-B. )
Fig. 11 is also a typical installation and can be varied to
suit requirements. NOTE: Holes drilled should be 1/32"
oversize. Additional bolts can be added where need is
