1. Place the steering gearbox in a press, then remove the cylinder end seal (A) and backup ring (B) from the gearbox by pressing on the special tools.
   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 brake the backup ring, and the cylinder end seal would remain in the gearbox.
