1747: the Transmission and Driveshaft

Now that I’m back from Cavallino, it’s time to get back to work on the cars. I’m in the process of getting the score sheets back from David Carte, the Class Judge, so I can see what points I missed, and how to improve for next time. I made a list of things I would improve on 3553, but am still proud of the car and the work we did so far. There’s always room for improvement, and I’m up to the challenge!

While I was in Florida, François reinstalled the freshly balanced flywheel and clutch assembly in the PF Coupe. The old pilot bearing was seized pretty well in place, but was removed and replaced with a new one. My job was to put the transmission back in and reconnect everything from that point back.

The transmission mounts were pretty worn out, so I’ll have to source new ones. These are similar to the ones used in British cars using the same overdrive unit, so with some slight modifications, they will work. It looks like the Ferrari factory modified these already by grinding away the mounting tabs to fit in the PF Coupe.

This overdrive unit has a third center rubber mount that I’ll have to locate. It’s not as worn as the other two, but I’ll see if I can find a good replacement.

I’ll still be able to get the rubber mounts in place later, so I reinstalled the drive shaft, u-joint, and rubber doughnut. With the cotter pins in place, the drive line is just about buttoned up.

There has been a lot of discussion about FIAMM Horns on the Vintage Forum, but nothing on an earlier set up made by Marchal. 1747 was equipped with a Marchal unit, but it had later hose clamps and vinyl hoses for the horns. I’d love to install the correct hoses, but was wondering if anyone knows what was right? The FIAMM horns have read hose, but I’m almost positive the Marchals used something else.

Parker Hall sent me pictures of his PF Cabriolet years ago, and they look to be a different Marchal horn, but the hose color looks to be clear beige.

The tops and tags look different to 1747, but perhaps the hose color is something I can match for 1747. Thoughts anyone?

Just a reminder, I’m looking for a new Vintage Ferrari Project. If you have, or know of a restoration project, please let me know. It would be great to restore another car on this website! My E-mail.
