8.13.7 Install the retaining ring (87) onto the output shaft (20).
8.13.8 There is a recess (a) in the worm gear (18) in which the retaining ring
fits. Be sure to position the worm gear so that the recess faces the
short side of the output shaft. Install the key (86) and press the worm
gear onto the output shaft so that it fits tightly to the retaining ring.

8.13.12 Before final installation, set the output shaft roller bearings. To do so,
install the top cover (6) and secure it with the screws (54). Torque the
screws to 25 Nm (18 ft.lbs.). Set the roller bearing by striking the output
shaft with a rubber mallet. You should be able to turn the output shaft
by hand and there should be virtually no end or side play.
8.13.13 Remove the top cover.
8.13.14 Install the input shaft. Rotate the input and output shafts as necessary
to align the gears.
