HEADLIGHT MOTORS

[VETTE1966]

My headlight motors on my 66 roadster are giving up the ghost--both are cranky and hardly move, especially in weather below 80 degrees (must have some old gummy-stuff inside or?).

Any suggestions on how to best pull the motors out and where to send them for repair? Do I have to pull the hood off? I don't know if I'm comfortable repairing them myself especially if they need new parts like an armature. I have seen such repair service with the Corvette Centrals of the world for like $150 per motor but I don't know how well they do and what's a fair price--anyone with experience in any of this??? thanks.

...search for threads here on this topic....99% certain that you need do nothing other than tear them apart, soak off the old hardened grease and replace (or swap from side to side) the pot metal driven gears that drive off the armature worm gear........

....i did mine without instruction.........take the hood off, look under the front clip and you will see the motors are attached with a metal strap and a clip as well as an electrical connector....pull off the connector, unscrew the bolt through the strap, pull the clip off the post and wobble the motor back and forth while pulling in toward the center - you may have to wobble the headlight housing also and/or turn the thumbwheel to take the lash out of the motor's geartrain....once you've done one, you can do thousands.....the motor is the same as used on the power electric radio antennas



...when i put them back together, i use white lithium grease....been about 5 years or so for one set and one side is JUST starting to get slow again

...good luck


here's the Long Island Corvette page for headlight motors...everything you need can be bought......http://licorvette.com/pdfcatalogfiles/cat/04.pdf

Nice pictorial of overhaul.

No need to remove the hood. Instructions are in your chassis service manual.

New output gears are about $50 a pair.

...i've done them both ways, with the hood off and on and the motor JUST fits through the space between the hood and the clip....if you have someone who can help you with the hood, why take a chance with the paint?


...yeah, if you can swing a wrench, you can do these motors

many guys swap the pot metal driven gear from one side to another and i've never had that good luck, mine were REALLY gouged out...cheap enough and the ONLY part that i have ever replaced on these motors
