Subject: Re: Headlight issue, what do you think. by BillH on 2011/6/25 1:24:02 OK, this peaked my curiosity. There is an adjustment on the worm gear shaft. This is not much different from the C2 drive/worm. If you look at the last 2 pics here, the last pic shows the adj. screw and locknut (lefthand side of the gear housing). that set screw pushes on the wormgear shaft and controls the degree of mesh. http://www.corvette-guru.com/modules/ ... p?topic_id=12705&forum=31 There is the same slotted screw and locknut on the C4. But first, check for play in the motor knob. You'll have to turn the knob 1/2 to 1 turn off the stop (when the headlight is fully closed). Now, is there any play in the knob at all either rotating it or pulling it up & down? There should be zero play rotating it gently back & forth. I don't think I'd try to adjust that with the motor on the car, I'd do it on the bench. What I would do is lightly tighten that slotted screw down until you can feel it hit the shaft. Then back it off an 1/8th turn and tighten the locknut. Note, I do Matt's linkage check first. In the pic, the screwdriver's pointing to the adj. screw. |
