FIFTH WHEELS

INSTALLATION INSTRUCTIONS

Failure to read, understand and follow the important information
contained herein may result in a hazardous condition or cause a
hazardous condition to develop.

Fifth Wheel Design and Intended Use:

1. For pulling trailers with standard SAE kingpins which are in good condition and
securely mounted or locked in position in the trailer.

2. Within the capacities stated in Holland literature.

3. As recommended in Holland literature (available from Holland or Holland distributors).

Holland Fifth Wheels are NOT Designed or Intended For:

1. Use with non-SAE kingpins, such as kingpins which are bent, improper size or

dimension, not secured to maintain SAE configuration, or which are installed in
warped trailer bolster plates.

2. Tow-away operation.

3. The attachment of lifting devices.

4. The transport of loads in excess of rated capacity.

5. Applications other than recommended.

Installation

General Recommendations

1. Every user and installer using Holland products either recommended or not
recommended by Holland, must thoroughly satisfy himself that the installation
procedure used is appropriate for the vehicle, product and application.

2. Consult the Holland literature for fifth wheel capacities and applications.

3. Consult the tractor manufacturer’s body builder’s book and the latest SAE and
D.O.T. standards for additional installation methods. Holland recommends the
T.M.C. Recommended Maintenance Practice 603B for installation procedures.

4. Determine the proper fifth wheel position. See SAE J701a for proper placement, as
well as the tractor manufacturer’s body builder’s book.

Note: The center of the kingpin locks must always be positioned on or ahead of the truck
rear axle.

5. Use Grade 8, 1/2˝ minimum diameter bolts and Grade “C” locknuts for mounting.

6. Bolt holes can be 1/32˝ larger in diameter than the bolt fastener. Bolts must be
adequately tightened using charted torque ranges in foot-pounds for the
recommended Grade 8, 1/2˝ diameter bolts. Larger diameter Grade 8 bolts and
coated fasteners may be used.

7. The bolts attaching the fifth wheel mounting angles to the truck frame require
hardened steel washers under both the bolt and under the locknut, unless flanged
head bolts or flanged head locknuts are employed.

8. Whenever a cutout is made on the mounting angle, such as required to bypass
suspension components, a 1˝ minimum radius should be used and bolts should be
placed within 1-1⁄2˝, but not closer than 1˝ of the cut, fore and aft.

Do not use U-bolts in fifth wheel installation.

ecommended at the rear of the truck-tractor frame.

9. Trailer pick-up ramps ar

10. When mounting to aluminum frames, follow the truck manufacturer’s
recommendations. Holland has available a stationary mounting angle intended for
use on aluminum frames; contact Holland or Holland Distributors for availability

11. Review, in addition, the specific information on the following pages for each type of
fifth wheel mounting, as well as “

Tractor Coupler Mounting (Kingpin or Fifth Wheel)
Straight Frame - Without a Body:

In addition to the general installation recommendations listed above, the
following specific recommendations should be followed:

1. If a folding kingpin is to be installed, see additional procedures under “Tractor Coupler
Mounting (Kingpin or Fifth Wheel) - Non-Straight Frame - With or Without a Body,” on the
next page.

2. Attach the mounting plate (kingpin or fifth wheel plate) to the frame using a full­length mounting angle, ASTM A36, 3˝ x 3˝ x 5/16˝ minimum on each side.

3. When initially positioning the coupler plate for frame holes, the full length of the
mounting plate should seat flush on the top and side surface of the truck-trailer
frame rails to prevent flexing
and give uniform weight
distribution. There should not
be a gap over the top of the
truck frame rails. It is also
recommended to chamfer or
smooth sharp edges and corners
of mounting materials whenever
contact is made with the truck­tractor frame. See
mounting diagrams. A
minimum of four (4) Grade 8˝,
1/2˝ diameter (minimum) bolts
must be used to attach each
mounting angle to the frame.
The distance between the bolts
must not exceed 8˝, except
when cutouts are required in
the mounting angles.

1. Full Angle Mounting – Preferred

In addition to the general installation recommendations listed on the previous
page, the following specific recommendations must be followed:

A. If a folding kingpin is to be installed, the following procedures must be
completed before going to step C:

1. The 40˝ dimension of the kingpin plate must be installed parallel with the
rear axle with the upright kingpin centered between the pickup sides.

2. Check under the floor in the area where the kingpin is to be located to avoid
interference with the differential, drive shaft or frame cross members. The
area should be clear 3˝ below the floor when the springs are fully bottomed.

3. Cut a hole in the truck floor
to receive the folding
kingpin box (see

Figure 4).

NOTE: The folding kingpin base is
offset. Cut three sides of the floor and
fold the flap down and out of the way.

B. Initially position the coupler
plate in the box or on the frame in
the desired position (at least 2˝
ahead of the rear axle). If possible,
the coupler plate should be
attached using a full-length
mounting angle (3˝ x 3˝ x 5/16˝
minimum, ASTM A-36) on each
side (see

Figure 2).

C. A minimum of four (4) Grade 8, 1/2" diameter (minimum) bolts must be applied

to attach each mounting angle to the frame rail.

D. Proper length tube spacers (3/4˝ I.D. x 1 1/2˝ O.D. recommended) must be used

to shim the distance between the mounting angle and the coupler mounting
plate (minimum of 4 per side).
