13. Install a commercially available bearing separator

(A) on the gearbox housing as shown.

14. Place an appropriate size deep socket wrench (B)

on the steering rack (C).

15. Set the steering gearbox in a press so the gearbox

housing points upward, then press the cylinder end
seal (D) and steering rack out of the gearbox. Hold
the steering rack to keep it from falling when
pressed clear. Be careful not to damage the inner
surface of the cylinder housing with the tool.

16. Remove the cylinder end seal from the steering

rack.

17. Carefully pry the piston seal ring (A) and O-ring (B)

off from the rack piston. Be careful not to damage
the inside of the seal ring groove and piston edges
when removing the seal ring.

18. Install a washer (O.D. 27.5 mm, P/N 94103-10400)

(A) so it will fit through the rack guide hole of the
gearbox housing, then position the washer on the
cylinder end seal (B). Make sure that the washer is
centered on the cylinder end seal edges.

19. Install the socket wrench with a 27.5 mm O.D. (A)

onto the 24 ’’ long 3/8 ’’ drive extension (B), and
carefully place it on the washer (C).

20. Set the steering gearbox in a press so the gearbox

housing points upward, then push the cylinder end
seal (D) for 5

6 mm (0.20

0.24 in.) by pressing on

the 24 ’’ long 3/8 ’’ drive extension end.

21. Remove the steering gearbox from the press, and

remove the washer from the gearbox inside.

22. Turn the special tool so it will fit through the rack

guide hole of the steering gearbox, then position
the special tool on the cylinder end seal (A). Make
sure that the special tool is securely positioned on
the seal edges.

23. Insert a 24 ’’ long 3/8 ’’ drive extension (A) and

place it on the special tool. Set the steering gearbox
in a press, then remove the cylinder end seal (B)
from the gearbox by pressing on the 24 ’’ long 3/8 ’’
drive extension.

Note these items when pressing the cylinder end
seal:

• Keep the tool straight to avoid damaging the

cylinder wall. Check the tool angle, and correct it
if necessary, when removing the cylinder end
seal.

• Use a press to remove the cylinder end seal. Do

not try to remove the seal by striking the tool;
striking the tool would break the cylinder end
seal, and the seal would remain in the steering
gearbox.

24. Before removing the valve housing (A), apply vinyl

tape (B) to the splines on the pinion shaft (C).

25. Separate the valve housing from the pinion shaft/

valve using a press.

26. With your finger, check the inner wall of the valve

housing where the seal ring slides. If there is a step
in the wall, the housing is worn. Replace it.

NOTE: There may be sliding marks from the seal
ring on the wall of the valve housing. Replace the
valve housing only if the wall is stepped.

27. Check for wear, burrs and other damage to the

must be replaced, replace both parts as a set.

28. Remove the snap ring (A) and sleeve (B) from the

pinion shaft.

29. Using a cutter or an equivalent tool, cut and

remove the four seal rings from the sleeve. Be
careful not to damage the edges of the sleeve
grooves and outer surface when removing the seal
rings.
