Assembly and Installation Your Q20 5th Wheel has been partially assembled, inspected and tested for fit, function and completeness. The Q20 5th Wheel is an engineered unit that has been designed and tested at the rating of 20,000 lbs. (trailer GVW). Unpacking 1 4 5 3 2 Be sure that the leg with the Warning and Instruction labels is placed on the side of the unit with the activation bar. The Q20 5th Wheel is packed in a reusable box. Contents will include: 1.
Calculating the Assembly height Assembly includes measuring the height requirement for the Q20 5th Wheel Head in relation to your trailer ride height at the kingpin box and skid plate. Ideally the trailer should ride as near to level as possible. The Q20 5th Wheel is adjustable from 13 to 17 inches from the pickup bed to the top of its Skid Plate.
Coupling And locking Cab View Indicator Positions Showing Coupled and Locked 5th Wheel Green dot is visible at this position in guide tube Flip lock is fully seated and lynch pin is installed Follower / Indicator Rod Becomes Visible through Window Preparing VEHICLE/ trailer TO COUPLE 1. It is advised to perform trailer connections to the 5th Wheel on a firm and level surface. 2. Multiple wheel chocks should be used in front of and behind trailer tires.
Preparing 5TH wheel to Couple Refer to “Cab View” on the top of page 5 and the coupling diagram on the bottom of page 5. 1. Note that Green Dot is visible (cab side) through Lock Bar Guide Tube and Indicator Rod is visible through window. 2. Flip Safety Lynch Pin Bail and remove Lynch Pin. 3. Lift Flip Lock, rotate clockwise and let hang. 4. Pull Lock Bar to full extension (approximately 3-1/2 inches) until Jaws activate and open, then release Lock Bar. 5.
coupling If you are using a Lube Plate on the trailer kingpin, you are ready to couple the trailer to the 5th Wheel. (Up to (2) 3/16" thickness Lube Plates may be used). If you are not using a Lube Plate, apply a high pressure wheel bearing grease to the 5th Wheel Skid Plate. Never position yourself or others under the trailer’s kingpin area (DANGER ZONE) during coupling and uncoupling.
Uncoupling AND Resetting 1. When parking it may be necessary to “unload” the forces on the kingpin by lightly backing “against” the kingpin. This maneuver helps put the kingpin and 5th Wheel in a “neutral” position. Once parked on a firm and level surface, set automatic transmission vehicles to Park and activate emergency brake, set standard transmission vehicles to Neutral and activate emergency brake. 2. Multiple wheel chocks should be used in front of and behind trailer tires.
Removal And reinstallation For your convenience the Q20 5th Wheel Hitch may be disassembled to ease removal. This section will discuss the three different way the Q20 hitch can be removed.
Reinstallation Reinstall the Q20 5th Wheel in the reverse order it was removed. If removal method was per option 1, please follow the steps below: a. Place the Mid-Section still securely bolted to the legs into the Mounting Rails b. Insert the (4) Mounting Rail Pins. c. Install the (4) Hairpin Clips. d. Retorque (4) Pilot Hex Bolts to 100 ft-lb. IMPORTANT: When installing the 5th Wheel Head into the Mid-Section, the LONG END of the Bearing Shaft is inserted into the Lower Bearing Assembly.
Maintenance Requirements Years of troublefree service may be achieved by adhering to a few simple maintenance points. Jaw Pin Grease Fittings Each Jaw Pin is supplied with grease through a grease fitting located in each Jaw. These grease fittings are visible from each side of the Q20 5th Wheel. Right grease fitting Left grease fitting Lower Bearing Grease Fitting The Lower Bearing Assembly is supplied with grease through the grease fitting centered in the Cast Base Plate.
Skid Plate Greasing The last lubrication point is the Q20’s Skid Plate. Liberally apply Grease to the Skid Plate surface if NOT using a Lube Plate. A highpressure wheel bearing grease is preferred. Apply as required between coupling and uncoupling the trailer from the Q20 5th Wheel. Apply Grease to Skid Plate if NOT using Lube Plate Maintenance Schedule Lubricate before each individual use and every 1000 miles thereafter.
