Headlight Activation Mechanism

NOTE: I have slight changed the order of these assembly steps from the printed instructions.

Step 1

Slide the D-shaped hole of the Gear onto the matching end of the Headlight Drive Rod with the pin of the Gear facing inwards, as shown.

This Gear needs to be fully seated on the Rod, until this small hole is exposed:

Step 2

Retain this Gear into place by installing one (1) AM screw just outside of it.

This is your friendly reminder to try using 3-in-One Oil on all screws going into metal:

Step 3

Press the Drive Rod End onto the open end of the Drive Rod until fully seated.

I had to use my crafting hammer to gently tap this Rod End into place:

Secure the Rod End to the Rod with one (1) more AM screw:

Step 4

Retrieve your Body assembly from the previous stage and place it upside down on a soft surface. You may want to apply a bit of lubricating oil or grease to these curved recesses of the Motor Bay Frame:

Step 5

Fit the Headlight Drive Rod assembly into the curved recesses, orienting it as shown:

Make sure the two ‘rings’ of the Drive Rod are sitting on either side of this right mounting recess, as shown:

Steps 6-7

Cover this Drive Rod with the Left Drive Rod Lock (marked ‘L’) over the left mounting recess and the Right Drive Rod Lock (marked ‘R’) over the right mounting recess, aligning the screw holes in both.

The smooth side of these Rod Locks should be facing up, as shown:

Secure these Drive Rod Locks into place with four (4) GM screws – two on each side, capturing the Rod in place.

Make sure the Drive Rod can easily rotate within the recesses. If it does not, slightly loosen these screws until it does:

Step 8

Secure one end of a Spring to this post of the Left Headlight Base with one (1) AP screw , as shown.

I did this a bit differently from the magazines to make installing these Springs easier. For instance, you may find it easier to put the AP screw through the end of the Spring first:

Then, loosely secure the Spring to the Headlight Base. The ‘body’ of the Spring should be facing away from the Base and be able to rotate around the screw, as shown:

Step 9

In the same way, secure another Spring to the same post of the Right Headlight Base with one (1) AP screw , as shown.

A spare Spring is included in case one is damaged or lost:

Step 10

Secure the Left Spring Lever (marked ‘L’) to the Motor Bay Frame near the Left Headlight with one (1) GM screw, orienting it as shown:

Likewise, secure the Right Spring Lever (marked ‘R’) to the Frame near the Right Headlight with one (1) GM screw, orienting it as shown:

Step 11

Secure the free end of the right-side Spring to the end of the Right Spring Lever with one (1) AP screw, as shown.

Again, do not fully tighten this screw as the spring should be able to rotate around the screw:

Then, pull the body of the Spring around the end of the Headlight Drive Rod so it is routed behind it, like this:

Step 12

In the same way, secure the free end of the left-side Spring to the end of the Left Spring Lever with one (1) more AP screw, as shown:

And as before, pull the body of this Spring around the end of the Headlight Drive Rod so it is routed behind it, like this:

These Springs act to pull the Headlights closed when they are turned off. It is important to check that both of them close easily on their own. If not, you may need to loosen the screws at the pivot points or shorten the Springs to increase their strength.

UPDATE: On my model, they closed *most* of the time, so I chose to shorten them by reattaching it further down the spring, as shown. This worked perfectly every time:

Thoughts


This headlight mechanism is an interesting one. I am curious to see how it works in the end!
