(Foldout 7,A). Remove eight bolts 28 and the lock-
strips.
(12) Remove hub 30 and gasket 31 from con-
verter pump 35.
(13) Do not remove bolts 36 unless new bolts
are needed.

c. Replacement of Needle Bearing
Assembly in Stator Assembly
(1) Place the stator assembly on a work table
front side upward. Tap the bearing gently from its
bore. Do not nick or scratch the aluminum bore during
removal.

Pump Bearing and Race (AT 543)
(2) Place a new bearing assembly into the
aluminum bore of the stator. Using bearing installer
tool J 23549 and handle J 24202-4, install the thrust
bearing (Figure 6–9).
(3) Drive the bearing assembly to a height of
0.025–0.035 inch (0.64–0.89 mm) above the shoulder
in the side plate (Figure 6–10). The installing tool will
seat on the stator area surrounding the bearing when
the bearing is properly installed.

the corners of the lockstrips against the bolt heads.
(3) Replace any converter pump flange bolts
36 necessary and make sure any weights are in their
original positions if pump bolts have been removed.
