Ferrari 330 Door Windows



The first step with assembling the windows on the 330GT restoration project was to make sense of the window motors. Each Vintage Ferrari model seemed to have different window motors the way they’re wired. Some come with permanent magnets with two wires, while others use four wires. They also connect to the gear boxes differently. This car had integral motors to the gearboxes that were not replaceable with a new motor, so I had to make sure they worked on the bench before installing them. I originally left them in the car, hoping the doors would not have to come apart, but the body shop had to remove them to redo the door skins. Unfortunately, they returned in a box with their winding cables in tangled in a box! I took them apart cleaned up the commutators and checked the brushes.

The Ferrari cable operated window winding mechanism leaves a lot to be desired, and each way the cable winds through the inside of the door is different. The first task for me was to string out the cable on my bench and clean up the internals of the motor. I was lucky to have a wiring diagram printed on one of the cable bodies so I could at least figure out how to make the winder motor work!

A box of very expensive weather stripping arrived in the mail.

The first piece of rubber that needed to go on the door was the wiper seal that fits up against the roll up window.

Each piece of weather stripping was carefully installed and cut to fit as perfectly as I could get it. This simple picture represents hours of fitting, polishing, cutting, and gluing. I still have to clean up my dirty fingerprints, but one door is coming along!

The 330 window frames remain attached to the door, so the u shaped felts that hold the roll up windows had to be installed in situ, so getting the miters perfect was a little more of a challenge.

Looking at these pictures as I posted them didn’t seem to show much, but don’t be deceived! You can just make out the cables for the window motor assembly were installed. Before this, I had to check all the guide rollers to make sure they were free. After spending a year at the body shop, a lot of dust and debris worked their way into the rollers. I washed them out and lubricated every joint to make sure the cables would work freely. The electric motors struggle to move the windows on their best days, so making sure there wasn’t any excessive friction was paramount.

The same description went for this picture. The quarter window seal was installed, along with the associated trim pieces after polishing. The crank mechanism was also installed and checked for operation. I guess I really should clean these parts before taking pictures, but it’s all a work in progress!
