8.Reach into the drive±end of the motor and dis- connect grease tubes.

a.On UP1 and AUP1 models, disconnect two grease tubes (21 and 22) from the inner bear- ing cap (51). Pull these tubes out through their hole in the frame. The sealing RTV in the hole will separate with sufficient force.

b.On UP2 and AUP2 models, disconnect one grease tube (21) from the inner bearing cap (51). Pull this tube out through its hole in the frame. The sealing RTV in the hole will sepa- rate with sufficient force.

c.On all other models, only one grease tube is used, connected between the inner bearing cap and the framehead. Remove this tube.

9.Place three 0.125 in. spacers (wedge shaped) around the armature in the air gap between the armature and the fields to maintain a vertical atti- tude of the armature and to prevent the armature from contacting the fields.

10.Remove bolts (10) and lockwashers (12) from the framehead (55). Insert bolts into the jackout holes in the framehead.

11.Install a lifting bail, Fig. 14, onto the end of the shaft.

12.Line up the hoist cable with the centerline of the armature before engaging the hook in the lifting bail on the end of the shaft. Engage the hook and lift slightly. With sufficient strain on the hoist cable to take the weight of the armature off the
