DISASSEMBLY *It may be easier to complete one side (Disassembly & Installation) then move to the other. 1. With the vehicle raised by the frame and supported so the tires just clear the ground, remove wheels/tires from the axles. (See Picture 1) 2. Disconnect any electrical wiring or hydraulic brake lines from the axles to avoid damage. (See Picture 2) 3. Place floor or bottle jacks under each axle. Lift both axles slightly so that the shackle link bolts can be driven out with a hammer. Remove existing spring mounting bolts, shackle link bolts, and center link. (See Pictures 3 & 4) 4. Remove OE plastic Bushings from leaf spring eyes. This is easiest with a punch or blunt object and hammer. (See Picture 5) These Will be replaced with new premium Bronze bushings. 5. Maintain jacks under the axles for re-assembly.

ASSEMBLY 1. Do Not remove the clamp brackets or clamp bracket bolts (The bolts need to be loose and should come this way from the factory. Remove the mounting bolt. (See Figure 4) Install The Flying Tiger unit into the frame hanger. (Figure 5) Lifting the unit into position with a floor jack may be advantageous as the unit is heavy. Clamp Brackets Position 2 Position 1 The Unit Can be mounted in 2 positions: Position 1: Use This Position In Most Cases. Install the mounting bolt in the bottom hole of the unit while positioned in the frame hanger. Position 2: Use this position with short center hanger brackets that will not accept the unit in position 1. This position may also be used to increase the ride height of the vehicle by approximately ¾ -1 if this is desired. Example of Position 1 Mounting Bolt Figure 4 NOTE: In specific cases where the side clamping plates cannot be used with a non-standard size center hanger, an alternative mounting is possible. If the unit will fit inside the center hanger and the hanger is tall enough, the unit may be mounted by removing the clamp brackets if (2) mounting bolts are used. (An additional pair of 9/16-18 X 3 GR 8 bolts with nylon locknuts will be needed) It may be necessary to drill an additional hole in the center hanger corresponding with the hole shown for position 2 above. 2. Once the unit is in place, install the mounting bolt. Starting with the bottom clamp bracket bolt, torque both clamp bracket bolts to 100 ft-lbs. Next, torque the mounting bolt to 100 ft-lbs. (In the afore mentioned case where the clamp brackets are not used, torque (2) mounting bolts to 100 ft-lbs.) Check that no water lines, electrical lines, etc. interfere with the suspension unit. Attempt to relocate any items that interfere with the operation of the suspension unit. Picture 6 Figure 5 3. Install bronze bushings in the leaf spring eyes. Using a lithium spray grease will ease the installation of the bushings. The included ½-13 X 1.75 bolt is supplied to drive the bushings in place without damage to the bushings. DO NOT hit the bushings directly with a hammer as this will damage the bushings. Insert the Picture 7 bushing in the spring eye, insert the ½-13 bolt into the bushing, drive the bushing into place by tapping the bolt with a hammer. (See Picture 6 & 7) FTS200IN REV.

ASSEMBLY 4. Install the grease-able bolts with the grease fittings is to the inside of the frame, this will allow access to the grease fitting without removal of the tires. (See Figure 5) Using a hammer and piece of tubing or ½ drive extension and hammer, drive the bolt in until the head is seated against the frame hanger and/or shackle link surface. Tighten the nut until it bottoms out on the bolt shoulder, 45-55 ft-lbs. 5. When installing the shackle links there are 2 positions available. Position 1 & Position 2, refer to figure 6 to choose the position right for your application. Lift the axles with the jacks into their normal operating position so that the spring eyes are higher than the eyes on the Flying Tiger unit. Attach the new shackle link assemblies, shackle links, grease-able bolts and mounting nuts. Tighten mounting nuts to 45-55 ft-lbs making sure the bolt head is seated against the shackle link surface. 6. Once both sides are complete, reinstall the wheels/tires and torque to the vehicle manufacturer s recommendations. 7. Grease all shoulder bolts with standard automotive axle grease or similar wheel bearing grease. Position 1: This position is used if shorter shackle links were removed from the vehicle or to raise the vehicle ride height. Position 2: This position is used if longer shackle links (3 or Greater) were removed from the vehicle or to lower the vehicle ride height. Figure 6 Figure 7 AIR KIT INSTALLATION The first step in installing the air kit is to determine the location of the air fill access valve/air pressure gage. It is recommended to install the fill/gage panel on the passenger side of the coach; this provides safety while checking the air pressure on the side of the road, however this can be mounted in many locations on the vehicle. Some prefer to mount this panel inside of a compartment or near the entry/exit of the coach for quick inspection of air pressure level. Be sure to check for potential interference and possible damage to other components before cutting any access/installation holes. Figure 8 Basic Air Line Routing (Gage/Fill Shown on Driver Side) LITHO IN USA CEQUENT TOWING PRODUCTS Page 5
AIR KIT INSTALLATION 1. After locating a suitable location for installation on the gage/fill panel: mark either (2) holes, 1 ¾ diameter, 3 3/8 apart from each other /or mark a 5 ½ Length X 2 ½ Height rectangle (Shown in picture 9) With a suitable tool, cut the opening for the air gage and fill valve. (Picture 8) 2. Using the sheet metal screws provided with the air kit, mount the air line attached to the Flying Tiger units by securing the bracket shown in figure 9 to the vehicle frame/underside. (The bracket comes factory installed on the unit). Be sure to leave enough slack in the line for the air spring to cycle, it can cycle up to 5 inches forward and aft. It is also important that the air hose must not contact any moving part of the suspension. Take caution not to run the screws into any electrical or tanks under the coach/trailer. Driver Side Unit T-Connector Picture 8 Picture 9 Figure 9 Passenger Side Unit Display/Fill Panel 3. Using the above diagram, determine the best routing path for the supplied air tubing. Determine a location for the T-fitting and measure the appropriate lengths for the tubing. Be sure to leave slack in the air line and avoid tight radius turns (less than 6 ) while routing the tubing. Cut tubing to length using the supplied tubing cutter tool (picture 11). Special care must be taken when cutting the tubing to avoid potential leaks in the air system: Picture 11 Cut Tubing squarely Max. 15 deg. Angle allowable 4. Install tubing sections in their appropriate locations. Insert the tubing into the mating port of the fittings making sure the port is clean and free of debris. Insert the tubing into the fitting until it bottoms (Push twice to verify that the tubing is inserted past collet and O-ring. (figure 10) Pull on tubing to verify it is fully seated. (To disassemble, press and release button, hold against body, and pull tubing out of fitting. Once tubing has been removed, it is necessary to re-cut the end of the tubing 3/8-1/2 back from the end.) Picture 10 Figure 10 LITHO IN USA CEQUENT TOWING PRODUCTS Page 6
AIR KIT INSTALLATION 5. Install the supplied wire clips and self drilling screws, position the clips in a manner which will keep the airlines tight to the belly of the coach. Take care not to leave the airline in a position to be snagged by road debris and/or interfere with the moving components of the coach/trailer. (Picture 12) 6. Connect the airline to the gage/fill panel (Picture 13), following the fitting guidelines from instruction #4. Install the 4 self drilling screws in holes provided in the panel. (Picture 14). 7. Install the provided decals on the coach, placement of the decal is suggested over the wheel well on both sides of the coach/trailer. (Picture 15) Picture 12 Decal Picture 13 Picture 15 OWNER S MANUAL INSTALLATION Picture 14 AIR PRESSURE ADJUSTMENT Unlike most air suspension products on the market, adjusting the air bag pressure will not raise/lower the ride height of the vehicle. To set the pressure first inflate to 100 psi (this seats the air fittings). Then reduce the pressure to, 5 PSI per 1,000 lbs. of coach weight ex: for a coach weight of 15,000 lbs, the initial pressure setting is calculated by 15000 1000 = 15 X 5 = 75 psi. This will vary depending on the loading of the coach and should be adjusted according to personnel preference. If you experience a harsh ride reduce the pressure of the system. If you feel that the ride is too soft, add air until the ride is satisfactory. LITHO IN USA CEQUENT TOWING PRODUCTS Page 7
HELPFUL HINTS OWNER S MANUAL INSTALLATION If the system is leaking air, set the pressure to 50 psi. Using a solution of dish soap and water, apply solution to all fittings. Inspect for the formation of bubbles. If the leak is at one of the push in fittings attempt to re-cut the air line according to the Instructions and reinstall the connection. Re-apply the soap solution to confirm the leak is no longer present. If the leak cannot be traced to a fitting connection, the air gage and the fill valve are the most likely pneumatic parts to leak. The system may loose pressure over an extended time period and this is considered normal, however leaks which loose pressure in just a few hours should be addressed. The suspension can operate without any air in the system in cases where travel is necessary. It should be noted that prolonged use in this condition can result in accelerated ware to the stop plates and the performance benefits of the suspension will not apply when there is no air in the system. The air spring may return to a position other than center, this is not abnormal. There is no lubrication required to the Flying Tiger Suspension unit, however the greaseable bolts should be part of the routine maintenance on the trailer. There are three natural factors that will affect the air pressure in the system; Temperature, Altitude, and Loading of the coach. A change in altitude of 3000 4000 ft. or more, a change in temperature of 40 deg or more, and/or 500 lbs change in the loading of the coach could result in a 2-5 psi. reading of the system pressure. If these conditions are temporary, no adjustment to the air pressure may be required.
