Ouch! Ferrari 360 Gearbox

[blueg33]

I'm interested to know if other 360 owners have had this problem

I put my foot down to make an overtake and there was a small bang and I lost all drive. I assumed that the clutch has suddenly gone (I was expecting it to go soon)

Turns out that the fault was not the clutch, but a sheared input shaft in the gearbox which as well as being an issue in itself has damaged various gears by spreading chunks of metal around the box. Looks like it may have been caused by a collapsed bearing but we can't be sure.

So its a new (rebuilt) gearbox for me. Anyone else experienced this issue and if so what were the symptoms?

I haven't driven the car since the summer as work issues meant that I couldn't get around to fixing it. I'm looking forward to getting back working even if I am not looking forward to the bill. Doing the clutch as well, and a belt service and a few other odds and ends.

PS. As always, amazing service from Aldous at AV.

In all the years I had my 360 (about 7 or 8 I think) I've never heard of that happening before.

Mind you - I'd also never heard of them snapping cam variators and smashing the top end of one block to pieces - until mine did it and I found out it was a "known" issue!

Aldous hadn't seen it before either. Its annoying as I had the cash earmarked for some other improvements!

Thanks for the links.

I remember having something like this happen on a 355. Very similar was driving up a hill, bang and loss of drive.

Car was trailered in to the specialist I used at the time and repair was around £4k but that was 20 years ago.

It’s a lot more than that now!

It’s 23 years old m, 46k miles.

Apparently it’s a different shaft from the ones that fail in a 355.

More info to come

Oh interesting, please let us know which shaft it is exactly when you discover.

It’s the main input shaft. Looks like previous work was done on the box and it was assembled incorrectly allowing the shaft to float around. Also incorrect tools used as there are chisel marks on large nuts that seat the shaft.

New box is now installed and has been tested.

MOT failed Headlight bulb replaced, MOT passed

I collect next week.

Total bill including belt service, clutch, flywheel, thrust bearing, some coolant pipes, engine bearing seal etc just into five figures.

I think Item 6. It’s about 30mm diameter, a lot thicker than the other one which fails in 355’s

I have a vid where AV explain it.

I can’t fault their service.
