14.
Insert the shaft ( 2 ) into the piston ( 3 ). Be careful not to
damage the piston seals. Do not engage the piston gear
teeth yet.
15.
Looking at the actuator from the end opposite the shaft
flange, use the exisitng timing marks to align the gear
teeth on the shaft ( 2 ) with the gear teeth on the inside of
the piston ( 3 ). When the marks align, gently tap the flan-
ge end of the shaft with a rubber mallet until the gear teeth
engage.
16.
Install two bolts in the threaded holes in the flange. Using
a metal bar, rotate the shaft in a clockwise direction until
the wear guides are seated inside the housing bore.
