  21. 22. Place the cylinder in a press, then remove the cylinder end seal (C), backup ring (D), and bushing from the cylinder by pressing on the special tool end.
    NOTE: Note these items when pressing the cylinder end seal:
    • Keep 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 cylinder.
  22. 23. Carefully pry the piston seal ring (A) and O-ring (B) off the rack piston. Be careful not to damage the inside of the seal ring groove and piston edges when removing the seal ring.

  24. 25. Separate the valve housing from the pinion shaft/valve using a press.
  25. 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.

  26. 27. Check for wear, burrs, and other damage to the edges of the grooves in the sleeve.
    NOTE: The pinion shaft and sleeve are a precision matched set. If either the pinion shaft or sleeve must be replaced, replace both parts as a set.

  29. 30. Using a cutter or an equivalent tool, cut the valve seal ring (A) and the O-ring (B) at the groove (C) in the pinion shaft. Remove the valve seal ring and the O-ring. Be careful not to damage the edges of the pinion shaft groove and outer surface when removing the valve seal ring and the O-ring.

  30. 31. Remove the valve oil seal (A) and wave washer (B) from the pinion shaft.
    NOTE: Note these items during disassembly:
    • Inspect the ball bearing (C) by rotating the outer race slowly. If there is any excessive play, replace the pinion shaft and sleeve as an assembly.
    • The pinion shaft and sleeve are a precise fit; do not intermix old and new pinion shafts and sleeves.
