Replacement Headlight Gear For 97+ C5 Corvettes
These kits are complete. There is nothing else to buy!
Do not waste your time and money on the aftermarket plastic gears! They are very poor quality and typically last a very short time. Do it right the first time!!
Re-Engineered for even longer lasting life! Now upgraded to include a newly engineered special steel brace with a special plastic support bushing. I have noticed glue joint failures in the late 2000-2004 C5 plastic housing motors. Glue joint failures happen because the plastic that these headlight motors are made of does not take any adhesive well. The glue joint surface is small and once installed it has to take a tremendous force that occurs when the headlight gets full open and full closed and stops abruptly. For the late 2000-2004 C5 headlight gear kits I have added a special stamped steel brace with a special plastic bushing. This brace and bushing do two things. It applies a slight pressure against the side cover helping to eliminate side cover glue failures. But most importantly it adds a new bearing surface to support the shaft thus removing all the pressure of the shaft from the side cover and transferring it to this new brace. Once installed this repair should last the life of the car. The early (97-99 and some early 2000) C5's have an aluminum housing and do not need this special brace. Those headlight motor assemblies are very heavy duty and only require a new gear and rubber bumper.
Symptoms of a failed gear in the headlight motor:
The OEM plastic gear and the rubber bumper are the weak parts in these headlight motors. Once rebuilt with my new heavy duty gears the headlight motors should last the life of your car. The rubber bumper will not last forever but is made of a quality rubber. Like any rubber product it can wear out.
Some are not always sure where the thin white plastic washer goes. So I'm putting a picture here. It goes on the output shaft like this on both sides:
NOTE #1: There are 2 variations of the headlight actuator motor assemblies used on the 1997 and up C5 Corvettes. The 97-99 motor assembly (and some early 2000 models) is all aluminum and has a removable side cover that is held on with 3 machine screws. The gear kit for the 97-99 motor assembly includes a new side cover gasket. The late 2000+ motor assembly is partially plastic (the gear case is plastic - the motor is steel) and it has a glued on plastic side cover. This cover needs to be pried off (broken at the factory glue joint) to replace the worn gear. The cover is easy to pry off and I include a packet of urethane glue to reglue it back on. Included with each replacement gear is a packet of high temerature grease that will not dry out quickly like the grease used by the original manufacturer. Also included: Complete step by step detailed rebuilding instructions and how to remove the headlight motor assembly from the car. Note from a C5 owner who is a chemist: "If you do accidentally get grease on the joint, one C5 owner says you can successfully clean it off with acetone, and the urethane adhesive will then bond to the housing."
NOTE #2: If you have a 97-99 C5 Corvette there is the possibility that one or both of the early aluminum type headlight motor(s) have been replaced with the newer 2000+ style plastic type headlight motor(s). To ensure you receive the correct kit please check to see if the headlight motor(s) in your 97-99 (and early 2000) C5 are plastic or aluminum. The aluminum housing style is the original equipment used on the 97-99 (and some early 2000) C5 Corvettes. They will have 3 screws holding the side cover one while the 2000+ headlight motor assemblies are plastic and the side cover is glued on. This newer style headlight motor change can occur because the 97-99 style motors are no longer available through GM. If a previous owner or a GM dealer has replaced a headlight motor in a 97-99 they may have installed the newer 2000+ style. A quick check will ensure that you order the correct rebuild kit.
Upgrade your older brass headlight gear kits with the new steel brace and better urethane adhesive. Click here for these parts.
Also fits the 1993-2002 Firebird and Saturn SC Coupe 1991-1996. Replaces damaged gear inside motor. OEM#'s: 16516653, 16516654, 16524229, 16524230.
Note: The pictures above show one side of the headlight motor. The opposite side is similar. On the early aluminum type headlight motors (picture on the left above) you can see the 3 small screws on the passenger side motor but on the driver side motor the 3 small screws are facing away from you and can not be seen.
This is a picture of the 2000-2004 plastic type housing with the headlight motor still in the car in the 2000-2004 C5. The ribs in the cover tell you it is the late plastic type. If the cover is smooth is is the early aluminum type.
