Wedge TR8 Headlamp lift motor repair

Now that daylight savings time has come, I drive the car home from work in the dark. Both my Ferrari & TR8 were making some pretty grunty sounds when the headlamps were raised & lowered.

I dis-assembled and fixed the Ferrari ones after the used replacements I bought were worse than my original ones.

I turned my attention to the TR8 this Saturday. For the record, the TR8 headlamp lift motors are WAY better in build quality than the Ferrari ones.

To fix the right hand unit I decided I needed to remove it from the car. The noise was somewhere in the motor and not in the linkage.

In case someone else heads down this path....here is what I did:

With the headlights raised, I disconnected the battery.

I removed the 4 attache screws for the rubber shroud and pulled that away.

Next I removed the four screws holding the light assembly and went to remove that. Pigtail is there and the disconnect is...um...inside the engine bay underneath the airbox! darn.

Removed the airbox and disconnected the wires and pulled the headlamp assy out.

Next I marked the four nuts/washers holding the empty headlight pod and removed them & the headlight pod from the car.

With the airbox removed I could see the four attachment bolts on the inside of the engine bay that held the lift mechanism in place as well as all the electrical connections.

With the electricals disconnected and pushed through the grommet I removed the four retaining nuts & two plates and removed the whole assembly out through the top of headlight hole.

The motor comes apart in two areas:

1. The drive gear side with was held in by three 7mm bolts
2. The motor house held on by two 1/4 bolts.

Once apart, some WD-40 to clean things up and some new grease on the drive gear and it all went back together without any issues.

Should have taken some pictures but I did this kinda quick.

Time: 3 hours

Silent now as they go up and down nice and smoothly.... :smile:

The internal electrical contacts and connections were far better than the Ferrari ones. I was simply amazed at the difference in weight, quality & design....

Lucas isn't all bad!
 
After sorting out the ones on the TR8 I had, I was impressed with the engineering that went into their design. The key, as with all electrical bits, is keeping contacts clean and the linkages lubricated. Kept up with, they are great.
 
I liked the ones that were on my Saab Sonnet the best. There was an aluminum rod similar to a cheap broom handle with a couple of offset bends in it and a T handle on the passenger compartment side similar to a hood release. The headlight mechanism was a hinged thingy that lifted up and locked when you pulled the handle and went back down an locked when you pushed the handle back in. Light, simple, effective. No chance the prince could leave you in darkness with this design.

3 hours? Quick?
Need to revise your clock there sport!
 
One of the rubber trim pads on mine decided that it didn't like being attached to the frame one day and decided to come loose and drop down AFTER the light was up. I was thankful for that. I simply wiggled it out until the next time that I had a chance to work on it.

Luckily Todd had some spare parts and when I went to pick them up I saw that the washers had fallen out of mine, so I got a couple of spare rubbers and went back home. On the way I stopped at Lowes and bought some fender washers of the same size and some of the new Super Glue made for rubber to metal. After taking the best of the rubber units and removing ALL of the washers, as several were loose, I cleaned the rubbers well and used the new SG to glue them together, with clamps on each one for an hour. Those things are on as tight as can be now and are not coming off for a long time.

While I was in there and I looked at everything and it seems pretty quiet and works well, so I left it alone.

Randy, thanks for posting this and I will bookmark it in the event that I ever have an issue with mine.
 
Paul, I think Clay has a good right up on that fix

I was also running back and forth to my neighbors house helping him swap out his brake calipers on his Vette while doing this in my garage :smile:

Vettes, Ferraris and a winning football team: Good neighborhood!
 
Ha! Sounds way sexier than this neighborhood looks! We are the stupid people that live within our means... I think the cars are worth more than houses!

..as for the Packers....time will tell......

From a drive up north last weekend:

That is one lovely picture Randy. I am partial to the Ferrari though......
 
I'd be afraid of Ferrari cooties.
Those will never rub off that Vette.
 
If you're Italian, you have nothing to fear.............and I am....
 
Ha-ha-ha-ha-ha..............I can laugh, I'm a former Vette owner, albeit with a warped sense of humor that most of them do NOT have............
