ASSEMBLY - CONTINUED
23.
Install two new guide halves (28) by hand in rack piston (22).
WARNING
Guide halves must be held in place during installation of balls. Failure to do so will result in balls being
trapped outside closed ball track, causing steering lockup and possible injury to personnel. Failure to install
all 32 balls in guide halves will also result in steering lockup and possible injury to personnel.
NOTE
•
Rotate input shaft slightly, if necessary, to ensure guide halves are properly seated.
•
If guide halves are unseated during or after ball loading, remove all balls and input shaft from rack pis-
ton and repeat steps 21 and 22.
•
Ensure all 32 balls are installed.
24.
Install 32 balls (29) in slot in guide halves (28).
25.
Apply a light coat of grease to new seal (27) and install in return cap (26).
26.
Using torx socket, install return cap (26) and two new screws (25) in rack piston (22). Tighten screws alternately to 168-
264 lb-in (19-30 Nm).
WARNING
Do not allow valve housing to move more than 2.72 in (69.1mm) away from rack piston. If this occurs, balls
will be out of place, resulting in possible loss of steering and injury to personnel.
CAUTION
During step 27, do not allow poppet (54) to touch valve housing (20). To do so will result in incorrectly pre-
set poppet.
27.
Rotate input shaft (2) into and out of rack piston (22) several times while checking for smooth movement.
28.
If input shaft (2) does not move smoothly, remove balls (29) and rack piston (22) and repeat steps 21 through 27.
