clutch

Post by mark »

Well, after a few long trips this summer in the 365 gt, it became apparent that the clutch needs adjustment. Easy enough, except that I found that I am running out of adjustment. A new clutch for xmas?

I think I should plan my attack. So far I have not seen anything in the literature that I have which describes the process. It appears that the torque tube will need to be moved aft. Do I need to disconnect the 1/2 shafts? Is it necessary to remove the center console and the shift tower? Once the bellhousing is separated will I need to support the back of the engine, since it rests on only 2 points? Oh, and I assume the usual while you are at it kind of stuff: Rear main seal, surface flywheel, pressure plate, t.o bearing etc.

Any advice on this procedure would be appreciated.

Cheers

Hi Mark,

I'm pretty sure you won't have to disconnect the half shafts, as there should be enough movement to slide everything back. The engine should be fine on the two front mounts. They're pretty beefy. I'll have a discussion with Francois and get you some more details.

how are your synchros? when I replaced my clutch, I took the opportunity to drop the box and replace the synchros since 90% of the stuff you're having to remove to get to the clutch you would also have to removed to do the tran work.

Thanks for the suggestion, my 3rd gear syncho. is a bit dodgy on the down shift. So are you saying that the trans needs to be pulled in oder to do the clutch? If so then that probably means removing the interior console and front seats.

My memory is that the torque tube had to be removed to get the tran to slide far enough back to access the clutch. I don't think I would have needed to entirely remove the tran to do the clutch, but I believe that 90% of the things that need to be removed to do the clutch job are also needed to be done to remove the tran. Once that 90% is done, dropping the tran is easy. My memory is also that the lower a-arm pans had to be removed, and the exhaust hangers on the back half of the car had to be removed to push the exhaust out of the way far enough to access the differential connections, since it also has to be scootched back. This was three years ago; I'd be happy to have guys like Tom and Zac who do this stuff every day weigh in.

Also, we did not remove the seats; just remove the screws holding the console and the shift boot rings/rubber and carefully put the console upside down on the seat - careful not to pull too hard on the wires for the wondow switches. Depending on your year, you'll either have two or four of them and then the wires for the back ashtray light (this is when you wish you had a race car to work on .. .). If you shove the driver's seat back far enough, you should be able to lift the carpet to access the rubber-plugged hole in the side of the tunnel for removing the tach connection on the side of the tran.

I can't edit my posts, and I keep thinking of things I wanted to say . . .

My first and second gear synchros had been dead for about five years (thus becoming a pro at the double clutch) when I decided that the clutch was also dead; so I never contemplated doing just the clutch. But it seemed to me at the time that most of the things I had to do to get to the clutch made dropping the tran a no-brainer.

Thanks Bryan:

You provided a wealth of information. I was able to follow 90% of it and I'm sure the other 10% will be obvious. Unrelated, I believe I saw your former
"girlfriend" motoring around Carmel last month. She looked and sounded fantastic!

Cheers

Hi Mark,

According to Francois, there transmission has to come out. He says there is very little room to slide it back, so taking the transmission/torque tube out will be the way to go. He also says the half shafts have to be disconnected, so I was wrong!

It's a big job.

ok - that explains why I remember removing the lower A-arm pans - to get to the half shafts! I did this job w/ Michael B on a lift and borrowed a friend's hi-lift transmission jack. Ohland supplied the synchros and clutch replacement kit. It was a big job

The last time we did one of these was Mark D's Queen. We did move the rear end back to gain clearance to remove the torque tube and them removed the trans. Replacing the synchros if you have the transmission out is well worth it as it may be the last time it's ever done. The trans is a heavy unit like you'd find in a tractor, there are some tools you ay have to make in order to dis-assemble it. Do yourself and get a parts breakdown from Geoff Ohland, don't order any parts until you get it apart and see what it needs. Make sure you look at the synchro hubs for wear as well, just replacing the synchros won't necessariliy fix your problem.

agree; when I pulled the top off the tran, there were scary pieces of burnt metal in there, so I took it to R. Garre w/ the synchros I had received from Ohland; we ended up having to order a few extra items before Richard could button it back up.

the tran is indeed a big beast, even with the tran lift - the right tool for the job - it was still a bear to wrestle up into place again.

Thanks Richard, Bryan, Tom and Francois!

Looks like I need to recruit a body builder or two for help. Seems logical though that after going to all that trouble, the synchros and so forth should be looked at.

Cheers
