Fifth wheels, Installation & maintenance instructions, Warning
XL-FW152-03
GENERAL INFORMATION:
1.
Verify that you have sufficient cab-to-axle
(C.A.) clearance on the tractor for the elevating
fifth wheel (
see Figure 1). A minimum of 60˝
is required. The 60˝ C.A. dimension is the
recommended minimum and is based on a 96˝
wide square-nosed trailer with a 36˝ kingpin
setting. More or less C.A. may be required for
other nose configurations, kingpin settings,
refrigeration units, etc.
Note that the pivot centerline of the fifth wheel
top plate should be located as near as possible
to the OEM’s recommended location and a
minimum of 1˝ ahead of the suspension
centerline, when in the down position. (
see
Figure 1.)
2.
The FW67 and FW69 Series lift wheels require
certain air components for operation. If these
air components are not obtained from Holland
Hitch Company, they should have the
following characteristics:
A. Air Tank – 9 cu. ft. capacity
(150 p.s.i. minimum working pressure).
B. Air Compressor – Minimum 14 cu. ft.,
24 cu. ft. recommended (150 p.s.i.
minimum working pressure).
C. Hose and fittings – Multipurpose hose –
medium and low pressure (see Figure 4 on
page 3, and parts list on page 5 for sizes).
C.A.
FIGURE 1
C. Mark the “T”style mounting angles for
required clearances. The mounting angles
may require cut outs to clear the bolts,
rivets, spring hangers, etc. on the frame.
A riser to elevate the fifth wheel assembly
and mounting angles may be required to
obtain clearance for the transmission or
crossmembers.

wheel unit. Make sure the mounting angle
is flush with each end of the fifth wheel
base, then mark the fifth wheel top plate
pivot location on the mounting angle.
B. Position the mounting angles on the tractor
frame with the fifth wheel pivot location
ahead of the suspension pivot centerline
as noted above in General Information.

When welding, use a procedure
which assures a sound, good
quality weld and which protects
the operator and others.
Overwelding may cause distortion
and damage, and underwelding
may not develop sufficient strength. A low hydrogen
process and AWS E70XX filler metal are recommended.
Take precautions to insure that the tractor electrical
system is not damaged by the welding.
