Can anyone point me to a specific procedure for a 1983 California-spec car?

Thanks!

 

Remove the "Bucket".3 screws. Don't drop them.

Adjusters are in there.

Adjust them. General rule is to have high beams point straight ahead (measure how high the lights are, park on a level surface, get the "hot spot" of the high beam to the same level, straight ahead of the car).

Put the Bucket back. Don't drop the screws.

 

Thanks, but this car is odd.

I read about a hydraulic adjustment system that crumbles over time, an electric system of infinite complexity, and now one that's inside the bucket. But these are all wrong for this car. Exploring, I removed the bucket and discovered that this particular 928 has the same adjustment mechanism as several American cars I've driven. Is my car the only one?

Nothing must be removed.
There are two holes in the chrome ring. A captive screw inside the top hole adjusts the light beam vertically, a screw inside the side one moves it laterally. It's that simple.

Now the trick is to get the bucket back on the car without ... ... dropping a screw!

 

Ahh. I have H4s the adjustment is inside the bucket.

The electric and hydraulic adjusters are Euro-spec. It's a feature that allows the driver to raise or lower the beam a bit to adjust for varying weight in the back. You'd have a little **** by the parking brake, next to the fader **** and the hatch release (that you don't have).

 

Not odd at all. Just the same as every US pre-S4 that hasn't been upgraded to H4s.

 

What about the "bars" that hold the bucket assembly.? The pieces that attach to the end of the long rod..
I was jacking w this on pass side of the 94 last week as a bolt was missing.
Action does not seem as smooth as the 79.
Thx!

 

I have a switch like the one in the pic. From what I remember reading on Rennlist it's an hydraulic system that works with silicone oil!!!
Mine never worked since I got the car....

 

Yup. That's it. I have a non-operational one too. I tried using the oil used in R/C shocks, as suggested in a thread that was posted, but I had no success.
Depending on my motivation, I may try to replace the lines. Fish tank aeration line was suggested as a possible replacement.

It's a really cool thing to have, if it works. With H4s, the beam cutoff is so sharp that I will light up the back bumper, but not the rear window of the car in front of me. If I have a bunch of stuff in the back, the bright part of the beam goes a little higher than I'd prefer.
