LoadLifter 5000 ATTACHING THE UPPER BRACKET 1. Set a roll plate on both ends of the air spring. The radiused (rounded) edge of the roll plate will be towards the air spring so that the air spring is seated in both roll plates (Figs.
LoadLifter 5000 ADJUSTING YOUR KIT 1. Align the assembly vertically and horizontally (Fig. 7). There must be sufficient clearance between the air springs, the frame, and the tire and brake drum at the maximum inflated diameter (7.0”). Tighten the upper bracket and mounting bolts for the bellows to 20 lb.-ft.
LoadLifter 5000 6. Center punch and drill one 3/8” locator hole through the frame at one bolt location and install one 1.5” washerhead frame bolt, over-sized washer, and lock nut. 7. Check the alignment of the upper and lower bracket once again to be sure that the distances between points X and points Y are equal and between 5 and 7 inches.
4. Cut the air line assembly (AA) in two equal lengths. NOTE When cutting or trimming the air line, use a hose cutter (Air Lift P/N 10530), a razor blade or a sharp knife. A clean, square cut will ensure that the line will not leak. Do not use wire cutters or scissors to cut the air line.
LoadLifter 5000 FIXING LEAKS 1. If there is a problem with the swivel fitting, then: a. Check the air line connection by deflating the spring and removing the line by pulling the collar against the fitting and pulling firmly on the air line. Trim 1” off the end of the air line.
LoadLifter 5000 Before Operating INSTALLATION CHECKLIST (To be completed by installer) Clearance test — Inflate the air springs to 60 PSI and ensure there is at least 1/2” clearance around each bellow, away from anything that might rub against them. Be sure to check the tire, brake drum, frame, shock absorbers and brake cables.
4. Look for a kink or fold in the air line. Reroute as needed. If the preceding steps do not solve the problem, it is possibly caused by a failed air spring — either a factory defect or an operating problem. Please call Air Lift at (800) 248-0892 for assistance. MN-391...
Q . Is it necessary to keep air in the air springs at all times and how much pressure will they need? For LoadLifter 5000 Ultimate, the recommended minimum air pressure is 5 PSI, but it can safely be run at zero air pressure.
LoadLifter 5000 GUIDELINES FOR ADDING AIR 1. Start with the vehicle level or slightly above. 2. When in doubt, always add air. 3. If the front of the vehicle dives while braking, increase the pressure in the front air bags, if equipped.
— from inside or outside of the vehicle . • For convenient, on-the-go control of your air springs, add an Air Lift on-board air compressor system. • Air Lift on-board air compressor systems eliminate the search for gas stations that have a working compressor, saving you time, energy and money.
