Maintaining the Joystick

1. Turn off the power to the game.

2. Open the control panel and disconnect the harnesses connector. See Figure 3-1.

3. Disconnect the four-pin connector from the PCB on the bottom of the joystick. Take off the PCB.

4. Remove the three hex-head screws holding the PCB to the positioner plate.

5. Remove the four long screws through the lower housing, positioner plate, and upper housing assembly; these screws hold the joystick together.

6. Remove the actuator and the two slides.

7. Check the actuator half-ball, the pivot ball, and the shaft for dirt and wear.

8. Put lithium-base grease (Atari Games part no. 107027-001) on the actuator, the actuator half-ball,

CAUTION

Do not turn the long screws that stick out over the side of the PCB unless you are reassembling the joystick.

CAUTION

Do not turn the long screws that stick out over the side of the PCB unless you are reassembling the joystick.

Figure 3-1 Maintaining the Joystick and the two slides. Also, press down the joystick control knob, expose the pivot ball and plunger, and grease the pivot ball and plunger.

9. Install the lower housing over the shaft so that the ends of the roll pin in the pivot ball fit into the slots on the inside of the housing. Turn the lower housing so that screw casings align with the holes in the upper housing.

10. On both of the slides, apply a small amount of lithium-base grease (Atari Games part no. 107027-001) to the corners and centers. Also put lithium grease on the two small round tabs on the slide with the ■ marked on the side and on the two long tabs on the top of the slide with the ▲ marked on the side.

11. Lay the slide with the ■ marked on the side on top of the lower housing. The ■ on the slide must be above the ■ on the lower housing.

Make sure the two small round tabs on the bottom of the slide fit into the two slots in the lower housing. See Figure 3-2.

12. Lay the slide with the ▲ marked on the side on top of the other slide. The ▲ on the slide must be above the A on the lower housing. The magnet and the two long tabs opposite it should point up.

13- Put lithium grease on the outside of the actuator. Install the long end of the actuator over the shaft and through the two slides.

14. Install the positioner plate over the slides so that:

■ The two long tabs fit through the two parallel slots on the bottom of the positioner plate.

■ The two magnets fit through the other two cutouts in the bottom of the positioner plate.

■ If you installed the positioner plate correctly, then the screw holes in the positioner plate will line up with the screw holes in the lower housing. If they do not, then you probably have installed the slide incorrectly.

15. Insert the four long screws into the screw holes in the positioner plate. Tighten the screws until the head of each screw touches the positioner plate.

16. Tighten the screws so that the assembly is held tightly together and the joystick handle returns freely to the center position. If the handle does not return, loosen the screws until it does.
