MOUNTING PLATE Is not included. 2. BEAD RING BOLT May be one of four varieties. 3. NUTS AND LOCKWASHERS are included with the part. 4. BELLOWS Wall gauge is approximately 1/4". 5. GIRDLE HOOP Wire wound type shown, molded into the bellows. 6. BEAD RING Upper and lower. Countersunk steel type shown. May also be of a second stamped steel variety or made of aluminum. 1. AIR INLET 1/4" NPT is standard. 3/4" NPT is also available for most parts. 2. BLIND NUT 3/8-16 UNC thread x 5/8" deep (two or four each plate depending on part size). Used for mounting part. 3. UPPER BEAD PLATE (9 gauge carbon steel, .149"). Permanently crimped to bellows to form an airtight assembly which allows for leak testing before the unit leaves the factory. Zinc/chromate plated for rust protection. 4. GIRDLE HOOP Wire wound type shown, molded into the bellows. 5. BELLOWS Wall Gauge is approximately 1/4". 6. LOWER BEAD PLATE Usually the same as upper bead plate, except without air inlet. 1. AIR INLET 1/4" NPT is standard. 3/4" NPT is also available for most parts. 2. BLIND NUT 3/8-16 UNC thread x 5/8" deep. Used for mounting the part. 3. BEAD PLATE (9 gauge carbon steel, .149"). Permanently crimped to bel- lows to form an airtight assembly which allows for leak testing before the unit leaves the factory. Zinc/chromate plated for rust protection. 4. BELLOWS Wall gauge is approximately 1/4". 5. BELLOWS END CLOSURE (steel) Permanently molded into the bellows. 6. PISTON May be made of aluminum, steel, plastic or hard rubber. Held to the bellows by a bolt which screws into the bumper stud. 7. BUMPER STUD A permanent part of the bellows end closure. 8. THREADED HOLE May be used for attachment to mounting surface. CRIMPED BEAD PLATE AIR SPRINGS Use the blind nuts for attachment. This is accomplished by bringing bolts (two or four depending upon air spring size) through the customer supplied mountIng plate and tightening into the blind nut. If this bolt is too long, it may fracture the bottom out of the blind nut. 3/8-16 UNC Blind Nut, 5/8" Deep 5/8" To Air Supply Customer Supplies Mounting Plates Bolts & Washers Tightening Torque on the blind nut: 15 to 20 ft.-lbs. Customer Supplies Mounting Plates Nuts & Washers STUD ADAPTER 1/2-13 UNC Thread 3/8-16 UNC Thread 1.35 If a protruding bolt rather than a blind nut is preferred to attach the air spring, a STUD ADAPTER is available from Firestone: 1.35 TANK VALVE One method for inflating air springs (primarily used in Airmount isolator applications) is with a tank valve: An air hose chuck is used (as inflating a tire with an air line). Care must be taken to periodically check the pressure within the air spring, because air will slowly permeate through the rubber/fabric bellows.
