Installation Instructions

General Mounting Instructions

Do not

modify and/or customize any fifth wheel

or mounting assembly without prior approval from
Fontaine. Modifying or welding to the product
without approval will void product warranty. Only
Fontaine authorized procedures are acceptable.
Welding must be performed by an AWS certified
welder.

Note: The 3000 Series top plate is made

of ductile iron.

2. Installation shall be in accordance with DOT

regulations, state and local ordinances, SAE and TMC
practices and standards, and tractor manufacturers’
recommendations.

3. All fifth wheels shall be located so that the tractor and

trailer will maintain clearance at all times. On sliding
fifth wheels, it may be necessary to “block out”
forward slide positions.

4. All mounting fasteners must be a minimum of:

5/8" (16.0mm) diameter - Grade 8 bolts

5/8" (16.0mm) diameter - Grade C lock nuts
5/8" (16.0mm) diameter - Hardened flat washers

5. Outboard mounting angles shall be ASTM-A-36 or

equal with a minimum thickness of 5/16" (7.9mm).

6. Inboard mounting angles must have a 4" (101.5mm)

minimum vertical and horizontal leg and shall not
be less than 36" (913.7mm) long. (Stationary angle
mounts only)

7. Outboard mounting angles must have a minimum

horizontal leg of 3" (76.2mm) and vertical leg of
3-1/2" (88.8mm).

8. The full length, horizontal flange of the outboard

mounting angles must be at the

same elevation

the truck frame. The vertical leg of the angles must
fit flush with the truck frame.

Warning: Failure to

follow these specifications will void warranty and
could effect product performance.
