can see if your timing marks are lining up. When they do,
tap the piston (3) in until the gear teeth mesh together.
Tap the piston into the housing the rest of the way until
it bottoms out.
10. Install the shaft (2) into the piston (3). Be careful not to
damage the seals. Do not engage the piston gear teeth
yet.
11. Looking from the view shown, use the existing timing
marks to line up the gear teeth on the shaft (2) with the
gear teeth on the inside of the piston (3). Now tap the
flange end of the shaft with a rubber mallet until the
gear teeth engage.
12. Install 2 bolts in the threaded holes in the flange. Using a
bar, rotate the shaft in a clockwise direction until the
wear guides are seated inside the housing bore.
13. Install the stop tube onto the shaft end. Stop tube is an
available option to limit the rotation of an actuator.
