a. On UP1 and AUP1 models, disconnect two
grease tubes (21 and 22) from the inner bear-

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
