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.

Air Lift Fifth wheels

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.
