NO-SLACK®II ASSEMBLY

Before rebuilding the assembly, check to make sure that there are no cracks in the cross members or other components. Also check bracket pin holes to ensure they are not worn oversize (pins should fit snugly). Under no circumstances should a fifth wheel be repaired or used if any component (cross member, saddle bearing, etc.) is cracked.

Step 3: Unbolt and remove the bumper from the operating handle.

Step 3: Insert the operating handle (Item Number 23) and bolt to the pivot mount. Use the provided bolt, lock nut, 2 washers, hairpin cotter and the bushing supplied in the kit (Item Numbers 26, 25, 17, 13, 9). Note the orientation of the bolt. The bushing used in this step is the largest of the three bushings in the bag.

Step 2: Unbolt and remove the secondary lock from the operating handle.

Step 2: Insert the timer (Item Number 24) and the timer spring (Item Number 11).

Step 1: Remove the sec-ondary lock spring and the bumper spring. Remove the pull handle cotter pin and washer then, slide out the pull handle.

Step 1: Always assemble the parts around a 2” kingpin or a 2” diameter shaft. Insert the jaw first and then the wedge below it (Item Number 12). Grease the jaw and wedge on the top and bottom.

Step 4: Unbolt the operating handle from the pivot mount and remove.

Step 4: Install the bumper (Item Number 22) and bolt to the operating handle. Use the bolt, 2 washers, lock nut and the bushing supplied in the kit (Item Numbers 21, 17, 10, 9). Note the orientation of the bolt. The bushing used in this step is the smallest of the three bushings in the bag. After installing the bumper, check to make sure that it can pivot freely.

Step 7: Pull out the cotter pin and then unscrew the rod from the wedge stop nut. Remove the wedge stop rod.

Step 7: Install the wedge stop rod (Item Number 4). Use the wedge stop rod nut and spring, as well as the 2 washers and a cotter pin (Item Numbers 1, 2, 3, 5). Note that the spring is placed between the 2 washers and the cotter pin is inserted through the rod behind the first washer. The rod is then screwed into the nut. Close the fifth wheel several times with a standard 2” kingpin tool. With the lock closed, adjust the wedge stop rod so that the end is 1/4 inch from the wedge.

Step 5: Remove the timer spring and the timer.

Step 5: Install the secondary lock (Item Number 20) and bolt to the operating handle. Use the bolt, 2 washers, lock nut and bushing supplied in the repair kit (Item Numbers 18, 17, 13, 9). Note the orientation of the bolt. The bushing used in this step is the medium sized bushing of the three in the bag.

Step 6: Remove the jaw and wedge.

Step 6: Install the pull handle (Item Number 19). Use the washer and cotter pin supplied in the repair kit (Item Numbers 17, 5). Attach the handle spring (Item Number 7) to the secondary lock and the bumper spring (Item Number 6) to the bumper. These springs are supplied in the repair kit. Now open and close the wheel to ensure that it works properly. Ensure the fifth wheel is properly lubricated before opening and closing the wheel.

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.

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 the added 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.

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 fifth wheel 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 top surface 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 a pry 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 bumper off 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 moly based 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 the kingpin 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 should move 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 and 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 skirt). 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.

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 model number: SL7ATB775024).

When the temperature drops below freezing, Fontaine recommends a thorough cleaning of the latching mechanism using a suitable cleaner or degreaser. Lubricate the fifth 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 reduce negative load stresses that can be harmful to the fifth wheel assembly and keep the bracket pins from making unnecessary noise from vibrations.

What is allowed vertical movement between fifth wheel plate and mounting plate?

What is allowed vertical movement between slide rail and slide bracket?

What is allowed horizontal (side to side) movement between fifth wheel plate and mounting base?

Up to 1/2" vertical movement is possible. This movement helps to reduce negative load stresses that can be harmful not only to the fifth wheel assembly, but to the truck frame also. This feature can only be found on Fontaine products.

Up to 3/16" vertical movement is possible. Any movement beyond the specified dimension may be due to wear or other problem. Steps should be taken to determine the cause. This dimension is to be used as a reference for service criteria only. For DOT out of service criteria, please consult the following website www.cvsa.org

How can I tell if 6000/7000/7000CC wheel is locked?

If the wheel is a No-Slack® 6000/ 7000/7000CC series the locking jaw and wedge must be across the throat of the wheel. In addition, the pull handle must be within 1" of the skirt of the wheel. The pull handle should be used as a positive lock indicator.

How much stationary jaw wear is allowed until rebuilding the fifth wheel will not eliminate slack/movement between the trailer kingpin and locking mechanism?


After determining the fifth wheel is in need of rebuilding, install the appropriate genuine rebuild kit (see page 2). Using the following steps, test the fifth wheel:

1. Insert a 2" test kingpin or plug.

2. With the fifth wheel in the fully closed position, use the illustration below to determine if the unit is within usable specifications.

If gap is less than 5/16" at any point along indicated area, then fifth wheel must be replaced


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 will resemble 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 the 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 wedge itself. 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 small 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 after coupling the secondary latch should be engaged. ALWAYS BE SURE TO CHECK THE PRIMARY AND SECONDARY LOCKS AFTER COUPLING.


Can I change the height of my fifth wheel?

Changing fifth wheel height can be as simple as changing the brackets. It all depends on the type of application, style of fifth wheel and the type 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 .125 (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 on the 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 fifth 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" maximum vertical movement between the wheel and base stand or any apparent deformation or material separation requires the pins to be replaced.
