The Windshield Wiper Motor

Step 01

Retrieve your Firewall assembly from the previous phase. Fit the post on the joined end of Firewall Left Hose A and B into the lower hole at this location on the Firewall:

Secure this hose ‘post’ into place from behind with one (1) EP screw:

Fit the free end of the shorter hose of Firewall Left Hose A and B into this slot on the Firewall.

No matter how hard I tried to push this into the slot, it would not fit. I ended up shaving a little bit off each side of it with a hobby knife until it fit snugly in there:

Step 02

Secure the larger hole of the Wiper Linkage Cam to this hole of the Windshield Wiper Motor (Bottom) as shown, with one (1) AP screw.

Do not over-tighten this screw, the Wiper Linkage Cam should still be able to rotate freely:

Fit the Windshield Wiper Motor (Top) onto the Windshield Wiper Motor (Bottom) as shown, aligning the post and pin. Then, secure these together from below with one (1) EP screw:

Step 03

Fit this Windshield Wiper Motor assembly on top of the Windshield Wiper Motor Bracket as shown, aligning the post and pin:

Secure the motor to the bracket from below with one (1) JP screw.

It sure seemed like this JP screw was too ‘thick’ to screw into the motor. I had to widen the screw hole some with a small drill bit to make it fit:

Step 04

Fit the D-shaped post of the Hood Release Catch into this matching hole of the Windshield Wiper Motor Bracket.

If this contacts the Wiper Linkage Cam, feel free to rotate the cam out of the way:

Secure this into place from below with one (1) DP screw:

Step 05

Push the pin of the Brake Fluid Reservoir Top into this hole of the Brake Fluid Reservoir until it is flush.

This Brake Fluid Reservoir Top should be installed on the end of the Brake Fluid Reservoir ‘without’ the alignment tab. Once again, these printed parts look really great!

Fit the alignment tab on the bottom of the Brake Fluid Reservoir assembly to this matching hole of the Windshield Wiper Motor Bracket:

Secure the reservoir into place from below with one (1) MP screw:

Step 06

Position this Windshield Wiper Motor Bracket assembly into this location of the Firewall, making sure the long hose of Firewall Left Hose A and Firewall Left Hoses B goes over the top, as shown.

There are four holes in the Firewall for this Windshield Wiper Motor Bracket assembly, as seen below. The screw holes are circled in red, while the alignment pin holes are circled in yellow:

This was a little tricky to fit in there, but mostly you just need to be sure the hoses on the right are above the bracket assembly and the alignment pins fit down into the Firewall so it sits flush:

Secure this assembly to the Firewall from above with two (2) CM screws, as shown:

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

Fit the end of the Wiper Transmission Arm (30E) into the open hole of the Wiper Linkage Cam, as shown:

Step 07

Secure the loop end of the wires of the Windshield Wiper Motor (Top) to this location on the Firewall as shown, with one (1) CM screw:

Step 08

Fit the notched end of the Firewall Left Hose C into this matching socket of the Firewall:

Secure the hose to the Firewall from behind with one (1) EP screw:

This step completes the Firewall assembly. It actually turned out very nicely!

Step 09

Retrieve your Chassis assembly. Fit the Firewall assembly behind the engine and under the ‘point’ of the Bulkhead Frame:

Fit the two posts on the bottom of the Firewall into these matching sockets of the Left and Right Side Tubular Frames (15A and 16A respectively):

Slide the pin of the Engine Intake Hose (08A) into this hole of the Firewall:

While holding the Firewall in position, turn the entire Chassis assembly over and secure the Firewall in place with two (2) FM screws:

Step 10

Push the pin on the end of Firewall Left Hose C into this hole of the Main Chassis (14A).

This was oddly difficult to install. The hose itself is hard plastic and has a shape that does not lend to pressing directly towards the hole. I had to slowly wiggle it into place:

Step 11

Fit the pin on the end of the rubber Distributor Cable (09E) into the matching hole in the end of the Ignition Coil (31B).

This was a very loose fit, so I used a drop of super glue on the Distributor Cable pin to hold it in there:

Thoughts


This phase had many things to assemble and install so I enjoyed it greatly! Any time we add a big piece to the car, I feel a sense of satisfaction. All of the parts in this phase are plastic.

Running Total of screws used so far: 216
