. 6. Using a safe lifting device, stator handling tongs, or chain and lift hooks, lift stator assembly from gear case adapter. If necessary, lift unit off bench about one inch and tap adapter housing with a soft faced hammer to free stator from adapter, Figure 59. FIGURE 59. STATOR REMOVAL 7. While stator is stiil on lift tongs or hooks, revolve stator to horizontal position and set it down on its side, Figure 60. FIGURE 60. REVOLVING STATOR FOR REPAIRS 51 the windings. DO not set stator down on open end, top or bottom, because stator weight can damage 8. Remove air baffle by loosening four locking screws, Figure 61. FIGURE 61. AIR BAFFLE REMOVAL c
9. Remove rotor and fan .by using a soft-faced hammer to tap on the adapter while holding the rotor assembly about one inch above bench with a hoist and rope sling, Figure 63. 10. A FIGURE 62 ROTOR HANDLING SLING A rope sling is the most suitable device for handling rotors, Figure 62. Iz3 CAUT~ON Uie care to prevent damage to the fan blades. Broken bladeswill throw the fan out of balance and reduce the air flow rate. If it is necessary to replace a damaged fan, sup- port rotor assembly horizontally and remove fan from rotor with a gear puller. Use the holes pro- vided in fan to attach gear puller tongs. 52 FIGURE 63. ROTOR AND FAN REMOVAL Use care to prevent damage to thefan blades. Broken blades will throw the fan out of balance and reduce the air flow rate. 11. Hold rotor in a suitable clamp and loosen nut on rotor-through-stud bolt as shown in Figure 64. FIGURE 64.
