diameter of the tire in order to spread the beads until they are seated properly. A length of rope wound snugly around the circumference of the tire before inflating will help to seat the beads. f. Remove the inflating needle from the valve, replace it in its carrying case and store the case in the Zip-Lip Bag for protection. SIDEWALL VALVE REPLACEMENT. a. b. NOTE With normal care and proper inflation, the tube- less tire valve will last the life of the tire. However, if a valve should be found to be leaking it can easily be replaced. Deflate the tire by inserting the inflating needle into the sidewall valve (according to instructions given in paragraph 2-2c and d above) and remove the valve core from the inflating needle to insure complete deflation of the tire; then remove the tire from the wheel. Cut off the inside shoulder of the sidewall valve to be removed with a pair of pincers or side-cutting pliers. (See Figure 1.) CAUTION Use extreme care to avoid damaging either the tire liner or the sidewall rubber under the head of the valve. Any kind of cut or damage of the rubber in these areas may impair or destroy the air retention properties of the tire. -3- C. From the outside of the tire raise the blue valve head and use a pair of pliers to pull the valve out of the tire. d. e. Place a small amount of cold patch rubber cement into the valve hole of the tire and on the thicker part of the tapered portion of the replacement valve. Insert the small end of the tapered replacement valve through the valve hole in the tire wall from the outside. (See Fig- ure 1.) f. Wipe the cement from the part of the replacement valve pro- jecting inside the tire%;B grasp the tapered end of the replacement valve with thumb and forefinger and exert a strong steady pull (slowly rotating the valve so as to spread the rubber cement between the body of the valve and the valve hole in the sidewall of the tire) until the head of the valve is seated in the recess. provided for it on the outside of the tire. g. h. CAUTION Be careful. Avoid pulling the entire replacement valve through the hole in the tire wall. Cut off the tapered extension of the replacement valve (just below the shoulder) on the inside of the tire with a pair of pincers or side-cutting pliers. (See figure 1). The tire may be mounted on the wheel and used immediately after inflation. 2-4 TUBE TYPE TIRES NOTE Goodyear Nylon, Rib Tread, Tube Type Tires are used with Wheel Assembly 95-300001-67 and 9532926. CAUTION To avoid possible injury to service personnel, the tire should becompletely deflated by removing the valve core before the wheel is removed from the aircraft. 2-5 MOUNTING TUBE-TYPE TIRES NOTE Before placing the tube in the tire, it is dusted with a small amount of tire talc. Do not use excessive amounts of tire talc. Soap or other solutions should not be used on the beads of the tire as these may cause slippage during service. 2-6 TIRE BALANCE 2-7 a. To obtain the proper balance of the assembly, the inner tube should be placed in the tire so that the yellow stripe is located at the red dot on the tire. Mating of the tire and tube in this manner will bring the unit into the balance tolerance prescribed by the manufacturer. INFLATION a. b. C. After mounting the tire and tube assembly on the wheel, divided type wheels should have the wheel half bolts drawn up evenly and torqued to the value marked on the wheel, before inflation. The dual method of inflation should be used when mounting all airplane tires. This consists of inflating the tube just enough to seat the tire beads on the wheel flanges, then removing the valve core and permitting the tube to completely deflate. This operation will permit the tube to equalize itself inside the tire and eliminate excessive stretching and thinning of the tube in the rim base section. Reinstall the valve core and inflate the tube to approximately one-half the operating pressure. CAUTION The tube should not be inflated to full operating pressure until the tire, tube and wheel assembly is mounted on the aircraft. -5- SECTION III OVERHAUL OF WHEELS 3-1 MAIN WHEELS 95-300001-1, 95-300001-73 and 95-300001–67. 3-2 DISASSEMBLY a. Completely deflate the tire. b. C. d. e. Remove the wheel assembly and deflated tire from the airplane as a unit, taking care not to damage the bearing seal or the bearing cone. Break the tire beads away from the wheel flanges by pressing with the heels of the hands or carefully stepping on the tire while the wheel lies flat on a clean area. CAUTION DO NOT USE TIRE TOOLS. They may damage the wheel flanges or tire beads and prevent proper air retention. Remove the self-locking nuts (2) and washers (3) from the wheel bolts (4). Separate wheel halves (6 and 8), ring disc (5) and remove the tire. NOTE Bearing cups (7 and 9) are shrunk fit into the wheel halves (6 and 8) and should not be removed unless replace- ment is necessary. If a bearing cup. is to be replaced, the wheel half must be heated, either in boiling water for 30 minutes, or in an oven not to exceed 149°C (300°F) before attempting to remove or install a cup. 3-3 CLEANING, INSPECTION AND REPAIR а. Clean all METAL parts in dry cleaning solution and dry with a lint-free cloth. NOTE Wash the bearing cones (1) last to keep the solution clean and place all parts in a clean place to avoid picking up foreign matter. b. Inspect the wheel halves for damage or cracks. If a casting is cracked or shows excessive corrosion, it should be replaced. Small nicks or gouges in the castings should be blended out and polished with fine (400 grit) sandpaper. Areas from which the protective coating has been removed or which show slight corrosion should be thoroughly cleaned and repainted with two coats of zinc chromate primer and two coats of aluminum lacquer -64 ·7 10 3 1B 1A 1B 1A Figure 2 Main Wheel Assemblies 95-300001-1, 95-300001-73 and 95-300001-67 MAIN WHEEL ASSEMBLY 95-300001-1 For Tubeless Sidewall Valve Tires) PARTS LIST FIG & INDEX NO PART NUMBER 2- 95-300001-1 -1 DESCRIPTION UNITS PER ASS'Y 13685XL AN363-524 AN960-516 Wheel Assembly Cone Bearing Nut Washer 1 2 3 3 AN5-34A Bolt, Wheel 3 95-300001-3 Ring Disc, Subassy 1 -6 9525531 Wheel Subassy Inbd Half 1 -7 13621XL Cup Bearing 1 -8 9525532 Wheel Subassy Outbd Half 1 -9 -10 13621XL AN6230B30 Cup Bearing 1 Seal, Wheel O-Ring 1 -7- 8 MAIN WHEEL ASSEMBLY 95-300001-67 (For Tubeless Sidewall Valve Tires) PARTS LIST FIG & INDEX NO.
