No-Slack ® 6000 series (Driver side; SLTPL6000 • Passenger side; SRTPL6000 • Air Actuated; AATPL6000)
50,000 pounds vertical load. 150,000 pounds drawbar pull .The innovative 6000 series fifth wheel is designed for standard and moderate duty applications. It
features the patented self-adjusting No-Slack ® locking mechanism with a positive secondary lock that
can only be released by pulling the handle. A safety trigger eliminates the possibility of false couplings
to prevent dangerous high hitching.
No-Slack ® NT (Driver side; SLTPLUNT • Air Actuated; AATPLUNT)50,000 pounds vertical load. 150,000 pounds drawbar pull .The new No-Slack ® NT is designed for 100% on-highway standard duty applications. The stamped
steel fifth wheel features the patented self-adjusting No-Slack ® locking mechanism with a positive
secondary lock that can only be released by pulling the handle. A safety trigger eliminates the
possibility of false couplings to prevent dangerous high hitching. The pull force required to open the
lock is only 65 lbs. The No-Slack ® NT also features savings of up to 50 lbs or more over competitive
products–helps fleets offset heavy 2010 emission system components. Optional air actuation with
in-cab air release (operates only when parking brake is engaged). Rated for on-highway use only,
including tankers. Only weighs about 228 lbs. Only use on LWO, LWI, ASB, APB or SMB mounts.
No-Slack ® 7000 series (Driver side; SLTPL7000 • Passenger side; SRTPL7000 • Air Actuated; AATPL7000)
55,000 pounds vertical load. 150,000 pounds drawbar pull.The 7000 series offers all the benefits of our 6000 series, but in a cast design rather than pressed
steel. It features the patented self-adjusting No-Slack ® locking mechanism with a positive secondary
lock that can only be released by pulling the handle. A safety trigger eliminates the possibility of false
couplings to prevent dangerous high hitching. 7000 series is also available as a blocked fifth wheel in
a variety of sizes to cover more frameless dump applications.
No-Slack ® 7000CC series Clean-Connect (Driver side; SLTPL7000CC • Air Actuated; AATPL7000CC
55,000 pounds vertical load. 150,000 pounds drawbar pull.
The 7000CC series Clean-Connect™ offers all the benefits of our 7000 series fifth wheels plus theadded benefit of a grease free top plate surface. With Clean-Connect™ technology the fifth wheel no
longer requires grease to lubricate between the top plate surface and the trailer coupling plate. This
eliminates the labor costs, materials and downtime associated with greasing the top plate surface.
Choosing the right fifth wheel – top plate styles
No-Slack ® X5092 Series (Driver side; SLTPLX5092 • Passenger side; SRTPLX5092)
75,000 pounds vertical load. 200,000 pounds drawbar pull.
The X5092 Series fifth wheel is designed for severe service applications. It offers the
same great features as the H5092 Series, plus additional steel reinforcement for even
greater capacity.
No-Slack ® H5092 Series (Driver side; SLTPLH5092 • Passenger side; SRTPLH5092 •
Air Actuated; AATPLH5092) 62,500 pounds vertical load. 150,000 pounds drawbar pull.The H5092 Series fifth wheel is designed for applications such as logging, chip hauling and
end dump trailers. This rugged fifth wheel uses a patented self-adjusting No-Slack ® locking
mechanism. Special steel cross members reinforce this wheel to reduce damaging fifth
wheel flex under heavy loads.

With the Fontaine Fifth Wheel complete product line
you can easily select the perfect fifth wheel for your
application. We offer top plates and mounting options
in a wide variety of sizes to handle even the most
demanding applications.
To specify the right fifth wheel for your application
two factors must be considered: load capacity and
service conditions.
“Weight” refers to the amount of weight that a fifth
wheel can handle. “Road type” refers to the operating
environment and the type of equipment used in an
application. “Travel type” refers to mileage between
stops.
You don’t choose a top plate based on “weight”
only. Consider service conditions because a heavy load
pulled on a paved road places less stress on a fifthwheel than a lighter load pulled in severe off-highway
conditions.
For more information on top plate selection
please refer to LT-076: Application guide available at
fifthwheel.com. Choose “Support and then choose
“Choosing the Right Fifth Wheel.” If you need further
assistance contact Fontaine Parts Connection at
800-874-9780.

1. Inspect the top plate and degrease if necessary. Lubricate the topsurface of the fifth wheel with thin layer of grease. Leave area around
the jaw and wedge free of grease.
2. Grease the mount brackets (4 zerks). Lift the top plate up with apry bar to ensure grease gets to the top of the brackets.
Hint: If the zerks will not take grease, remove top plate and clear the
grease channels.
3. Trip the locking mechanism with a pry bar by pushing the bumperoff its seat. Keep your hands and arms out of the fifth wheel throat.
Note: For cold weather maintenance, please see page 20
or visit our website at www.fifthwheel.com.
4. Separate the jaw and wedge with a screwdriver and press a molybased lubricant between the serrated surfaces (Mobil grease moly 50
or equivalent). Also press the lubricant in the kingpin contact area on
both the stationary jaw and the moveable jaw. Work the action of the pull
handle back and forth to spread the lube over all the surfaces.

2. Insert a dimensionally correct test kingpin tool
into the throat of the fifth wheel. Carefully push thekingpin in until the locking mechanism is activated.
Keep your hands out of the fifth wheel throat.
4. Check the travel of the wedge stop rod by pushing in on it. It shoulmove in 1/4" with hand pressure and then spring back out. To obtain a
proper setting, turn the wedge stop rod clockwise to reduce the gap an
counter-clockwise to increase it. Adjust until the free travel is 1/4".
Hint: If necessary, tap the wedge-stop rod with a hammer to release a
tight wedge.
3. Verify that the pull handle is in the fully locked position (within 1"of the fifth wheel skir t). Check the pull handle for straightness. If bent,
replace immediately with KIT-PUL-6000L or R.
1. Wedge stop rod adjustment is not required as part of the pre-service procedure. It is set during the final assembly inspection at
our manufacturing facility. At the first recommended P.M. (90 days or
30,000 miles whichever comes first) and every 90 days or 30,000
miles there after, the wedge stop rod should be adjusted per technical
Bulletin TB-012. Note P.M. intervals are recommended based on
standard duty applications. Applications more severe than standard
duty may require different P.M. intervals to ensure peak performance.

What about cold weather?
A
The installed height of all Fontaine models is measured from the top
of the truck frame to the top of the fifth wheel. For standard models
dimension “A” is a part of the model number. For example, if dimension
“A” in this diagram is 7.75 inches, it would appear in the model number
as 7750 (Example: SL7ATB775024).
To determine the length of travel on a sliding fifth wheel, measure the
slide rail and deduct 30 inches from the “X” dimension (for Xtra® heavy
duty models deduct 42 inches). For example, if dimension “X” above
measures 54 inches, deduct 30 inches, leaving 24 inches of actual
slide travel. For standard models this dimension is a part of the modelnumber: SL7ATB775024 ).
Separate jaw and wedge with screw
driver and grease full length.
Clean, oil and grease all moving parts (see arrows).

When the temperature drops below freezing, Fontaine recommends a
thorough cleaning of the latching mechanism using a suitable cleaner
or degreaser. Lubricate the fif th wheel prior to opening and closing.
Refer to figures below. Open and close the fifth wheel several times
to distribute the grease. Fontaine suggests the use of a moly-based
lubricant such as Mobil grease moly 50 or equivalent. Areas or regions
that experience extreme and/or prolonged freezing temperatures should
consider using a less viscous substance such as: 90-weight oil, diesel
fuel, kerosene, motor oil, etc. Fontaine recommends contacting your
specific lubricant manufacturer for guidelines on mixing compatibility of
any lubricant.

Which fifth wheel is best for my application?
Can worn bracket bushings be replaced
under warranty?
Fontaine has an application guide ( LT-076) that be obtained on
our website or by calling Fontaine Parts Connection.
No. Bracket bushings are a wear item and therefore not warrantable.
The bushings are not a structural component. They help reducenegative load stresses that can be harmful to the fifth wheel assembly
and keep the bracket pins from making unnecessary noise from
vibrations.

What is the warranty coverage?
Fontaine’s warranty is for five years covering parts for material and
workmanship. There are a few exceptions. See our existing warranty
standard or call us at for more information.
What is the recommended maintenance procedure?
For No-Slack and 3000 models, recommended maintenance is at least
every 90 days or 30,000 miles. All recommended practices are located
in the Fifth Wheel Handbook supplied with every unit shipped or may
be obtained by ordering from Fontaine. For 3000 models, lubrication is
recommended every 6 weeks or 15,000 miles.
What is the difference between wedge-stop rod
and knock-out rod
The wedge-stop rod serves as a slack adjustment and a knock-out
rod. A knock-out rod serves only as a emergency release in case the
wheel should ever bind up. Both type protrude through the side of
the wheel opposite the side of the pull handle. The adjustable type
requires a 1/4" gap between the tip of the locking wedge and the tip
of the wedge-stop rod when coupled to a 2" diameter pin. Proper
adjusting can be achieved by turning the hex head bolt counter clock
wise to increase the gap or clockwise to decrease the amount of
gap. The 1/4" will allow the lock to automatically compensate for
reasonable variances in kingpin wear. The non-adjustable type willresemble a rivet head or carriage bolt type head. This type is self
adjusting and will stay in constant contact with the tip of the locking
wedge when the wheel is in the closed position. Both of these are
spring loaded and may be struck with a hammer in the event the unit
will not release when trying to uncouple from a trailer.
How do the primary and secondary locks work on th
type of wheel I have?
The No-Slack ® 5000/5092 and 6000/7000/7000CC model wheels
carry the same primary locks. The primary lock is the jaw and wedgeitself. Between the mating surfaces of the two are small serrations.
The geometry of the serrations keeps the wheel from being able to
come open when the wheel is in the fully closed position.
5000/5092 models carry a two-piece pull handle in which the
bottom section when fully closed will drop in and down behind a sma
triangular piece located just inside the skirt of the wheel. This serves
as a secondary lock.
6000/7000/7000CC models have a slightly different feature to
serve as a secondary lock. A rotating latch located on the front on
the operating handle serves as a positive stop which will only release
when activated by the pull handle. The use of the pull handle allows
the latch to rotate enough to bypass its stop and open the wheel.If the pull handle is against the skirt of the wheel af ter coupling the
secondary latch should be engaged. ALWAYS BE SURE TO CHECK
THE PRIMARY AND SECONDARY LOCKS AFTER COUPLING.
Frequently asked questions
Can I change the height of my fifth wheel?
Changing fifth wheel height can be as simple as changing the bracket
It all depends on the type of application, style of fifth wheel and the ty
of existing base. These factors will determine just how high or low you
can go.
How much wear is allowed for a kingpin?
According to SAE J2228 - Kingpin Wear Limits, if the upper shoulder
which is 2.875" new or the smaller 2" diameter is worn more than .12
(1/8)" the kingpin should be replaced.
What if my fifth wheel is hard to open?
Make sure a pre-service lubrication has completed before unit is out
in service. Make sure the driver is backing tight against the trailer after
setting the trailer brakes. This will reduce any tension or pressure onthe locking jaw and wedge. DO NOT dump chassis air bags before
uncoupling from trailer. Make sure the wedge-stop rod is properly set to
the recommended gap. Make sure the truck and trailer are not in a bind
or twist (No daylight between top plate and trailer plate). Check for any
lower mount obstructions or interference underneath the wheel. Check
for damage to the fif th wheel. See troubleshooting chart on back cover.
How much wear is allowed on the bracket pins?
Any visible wear that allows the fifth wheel to exceed the 1/2" maximu
vertical movement between the wheel and base stand or any apparen
deformation or material separation requires the pins to be replaced.
