How do I measure a fifth wheel? How do I find my serial number? X 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). A Old style serial number (before 11/27/00). Serial number located on small rectangular tag on front of top plate. Note: position 3 and 4 of the serial number indicates the year built. New style serial number (after 11/27/00). Serial number engraved directly into the right side of fifth wheel skirt. Note: position 5 and 6 of the serial number indicates the year built. XXXXXXXXX XXXXXXXXX No-Slack front view No-Slack right side view What about cold weather? 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 Mobilgrease XHP320 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. No-Slack (6000/7000/7000CC) Clean, oil and grease all moving parts (see arrows). Serial number engraved directly into the left side of fifth wheel skirt. Note: position 5 and 6 of the serial number indicates the year built. XXXXXXXXX 3000 left side view Which fifth wheel is best for my application? Fontaine has an application guide (LT-076) that can be obtained on our website or by calling Fontaine Parts Connection. Can worn bracket bushings be replaced under warranty? Jaw and wedge Grease fittings Jaw Kingpin contact area 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. 5092 See page Sec B: 5 Wedge 3000 See page Sec C: 5 Sec E: 2 Separate jaw and wedge with screw driver and grease full length. 800-874-9780 www.fifthwheel.com
How much stationary jaw wear is allowed until rebuilding the fifth wheel will not eliminate slack/ movement between the trailer kingpin and locking mechanism on 6000/7000 series models? After determining the fifth wheel is in need of rebuilding, install the appropriate genuine rebuild kit. 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 How can I tell if a 5000/5092 wheel is locked? If the wheel is a No-Slack 5000 or 5092 series the locking jaw and wedge should be across the throat of the wheel. In addition, the bottom section of the two-piece pull should be in and down behind the triangular piece located just inside the fifth wheel skirt. Closed Side view Not closed Triangle piece NOTE: The two-piece pull dropping in behind the triangular piece Fifth wheel skirt NOTE: The two-piece pull not dropping in behind the triangular piece Side view Fifth wheel skirt Note: Bar is visible Triangle piece How can I tell if a 6000/7000/7000CC wheel is locked? How can I tell if a 3000 wheel is locked? must be fully retracted behind skirt notch and secured in place using the clip. Handle clip 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 must be within 1" of the skirt of the wheel. The pull should be used as a positive lock indicator. Closed 6000 series shown Not closed NOTE: Gap between pull and skirt of wheel less than 1 Fifth wheel skirt NOTE: Gap of 1" or more between wheel skirt and pull Skirt notch Fifth wheel skirt 800-874-9780 www.fifthwheel.com Sec E: 3
What is allowed vertical movement between fifth wheel plate and mounting plate? What is allowed vertical movement between slide rail and slide bracket? 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 1/2" vertical movement Up to 3/16" vertical movement is possible. Any movement beyond the specified dimension may be due to wear or another issue. 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 Up to 3/16" vertical Movement between slider bracket and rail 3/16" Side view Front view of bracket and rail What is allowed horizontal (side to side) movement between fifth wheel plate and mounting base? What is allowed horizontal (side to side) movement between slide rail and slide bracket? Up to 1/4" horizontal (side to side) movement is possible. Any movement beyond the specified dimension may be due to wear or another issue. 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 Up to 1/4" horizontal movement between fifth wheel and bracket stand Rear view of fifth wheel assembly Up to 5/16" horizontal (side to side) movement is possible between the slide rail and slide bracket. Any movement beyond the specified dimension may be due to wear or another issue. Steps should be taken to determine the cause. This dimension is to be used as a reference for service criteria only.

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. 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. 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 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 similar 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 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 serves as a positive stop which will only release when activated by the pull. The use of the pull allows the latch to rotate enough to bypass its stop and open the wheel. If the pull 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? Worn kingpins can cause various problems. It is recommended that kingpins with.080" of wear (1.920 minimum diameter) be refurbished or replaced because of the potential premature wear or damage that the wheel may incur. DOT out of service criteria is.125" (1.875 minimum diameter). Order kingpin gauge part # MSC-GAUGE. 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. How much wear is allowed on the bearing pocket? If wear is evident at any point in the bearing pocket channel that does now allow lubricant to flow evenly, then steps should be taken to ensure the unit is discarded. Failure to do so will cause damage to the mounting bracket stands. Good pocket channel Worn pocket channel 800-874-9780 www.fifthwheel.com Sec E: 5
