1. The tilt away steering consists of a vacuum motor, release cable, electric operated vacuum solenoid and drivers door switch. To start the car, drivers door must be closed, steering wheel must be locked down and automatic transmission must be in park or netural.
2. Removing the dash pad will provide access to the top and other wiring. Remove the left and right corner pieces (2 screws each), screws at steering column molding and botom of instrument cluster screws above glove box and 3 screws below window to front of dash pad.
3. When removing the dash pad take note of the wiring connections for ease of reassembly.
4. To remove the instrument panel, you will need to remove the remaining screws, speedometer cable, tachometer wires and the main wiring harness to the printed circuit at the back of the dash.
5. It will now be wide open for you to work on the wiring from the top. Note that the car will not run if the tachometer wires are not connected to the tachometer.
6. The vacuum motor is located below the dash to the right of the steering column, disconnect the wiring and vacuum connections and the pin connecting it to the steering wheel release cable.
7. It should be noted that the two red wires are required to extend the wiring harness and allow connecting the safety switch into the circuit. This is very important as it is part of the safety system of the tilt away steering wheel.
8. This shows the electric operated vacuum solenoid. When vacuum is available past this solenoid, the vacuum motor piston will be pulled to the rear, compressing the internal spring and releasing the steering wheel.
9. This is a front view of the vacuum motor, remove the two screws and the attaching bracket. Rotating the front cover clockwise will allow dissassembly of the vacuum motor to examin condition of internal parts.
10. The return spring is not shown, it would make contact with the left rear base of the piston assembly.
11. The lock down safety switch can be seen against the inside face of the front cover. When the piston moves to the right as the steering is locked down the button will be depressed and the contacts closed on the safety switch.
12. The piston seal has been removed, although this is not necessary. The wide part of the seal must face the rod side of the piston. Vacuum on the barrel end of the piston will pull the seal in contact with the vacuum motor barrel. I applied small amount of grease to insure a good seal.
13. Should you need to remove the steering wheel, the following pictures will guide you through the process.
14. There are 3 screws on the rear of the steering wheel that hold the cover in place.
15. With the cover removed and the horn wires disconnected, the nut holding the wheel in place will need to loosened.
16. Because the steering shaft is tapered, back off the nut only enough to allow the wheel to pop off the shaft.
17. Install a steering wheel puller, make sure the puller bolts fully engage the steering wheel threads. When the center jacking bolt is tightened and pressure is applied to the steering shaft, the steering wheel will pop off the shaft and be loose. Remove the puller and make note of the steering wheel position (there is a mark on the wheel and the shaft), on reassembly you will get it in the right position the first time. Remove the nut and lift the wheel from the shaft.
18. Cancel switch mechanisum and other wiring is exposed There are screws that keep the mechanisum in place, remove it only if required.
19. Check condition of wiring and repair as required.
20. The tilt away vacuum reservoir is located under the right front fender.
