Desperate Help Needed: 348 Transmission still not back together

Ok so my transmission is still not back together and I have 30 days now until the first track day of the year. There is a good majority of it back together (like the main, and lay shafts) but of course as in anything Ferrari I am in a major cluster-truck at the moment.

I needed to get the following set of gears that sit on the clutch shaft and the pinion shaft because mine were pretty much trashed once I got the transmission apart.

If you look at the below pictures you can see that the splines in the gears dont match up with the splines on the left hand side of the clutch shaft. Now here is the interesting thing...that clutch shaft pictured below and my old clutch shaft are EXACTLY the same part number and I cannot find any reference book that shows them being different however CLEARLY my old clutch shaft has the splines that line up with the gears pictured below (ie 10 splines) where as the new clutch shaft has like 4 billion splines on it.

Needless to say I am about to the point of atomic bombing my car at the moment as I just cant seem to win getting the right parts for this car because the damn thing has clearly different parts that share the same part number.

My guess is that the new clutch shaft I have pictured below is an upgraded one as the multitude more splines would be able to hold more torque (at least in my head than the original larger 10), but that doesn't help one when finding fricking parts.....arghghghghghghgh.

Anyone else out there ever seen this and can tell me if what I am seeing is indeed true or is my new shaft mislabled in some way? I am confused as all hell.

By the way I have to thank Daniel publically for sticking with me through the hassel of getting all these parts. He has been awesome.

I have faith in your Daniel trust me!

FBB you are right the damn original one has square splines on it. When I first ordered the new one from Daniel (pictured one) I basically just looked in my parts manual and order 145427 which was suppose to be the clutch shaft with the square pegs. Hell it even looks that way in the damn parts manual...if you look at the picture in the manual you can actually count the 10 splines. In my own boneheaded mistake when I got the new clutch shaft I opened the package, took it out and said "all by damned it a clutch shaft" and then sealed it back up and put it in the garage.

It never hit me until today when browsing Ricambi's site and looking at all the nifty pictures of parts I had to order that the splines didnt match up until I looked at part 145427 on Ricambi's site and then looked at the gears Daniel searched all over gods green earth to find for me. Needless to say there were a couple f-bombs dropped at that moment in my office.

I guess I am just confused right now as to what the hell part I have. It sure as sh*t is the exact same diameter inside and outside as my old clutch shaft, it has the exact same rear splines, is the exact same size where all the bearings mount, and is the same length. It looks, talks and acts like its from a 348 but sure as hell not mine.

Now once upon a time I had a 95 355 apart and I remember seeing the exact same clutch shaft as here....well I remember it had little splines where the drive gears went which makes me think did the later model 348's switch to this clutch shaft which then was carried over into the 355 until being replaced in 96-97 with a solid gear/clutch shaft assembly.

Needless to say I am stumped...why on earth Ferrari would replace the part and not really make reference to it being replaced is beyond me. Every piece of documentation I have shows 145427 being the exact part but as you can see below its completely not. Unless there is a set of gears specifically for this shaft that are magically not to be found on planet earth but some how exist in a parallel universe where Ferrari manuals are actually useful and unobtainium parts are actually made of hardened steel.

Thanks for the advice FBB and at least confirming that you to have seen the square 10 spline clutch shaft and I am not the only Ferrari in the world with one. I think I would be willing to offer up two cows and thirty bails of hay along with a set of Hoosiers for Erine's clutch shaft to disappear from sunny CA and reappear in my garage.

I know I have been a pain in Daniel's butt with trying to get all these unobtainium based parts here this winter and he has been awesome to me but I think we both are about at our wits end with trying to figure out what the hell these parts are and I figured I would call on the power of F-chat to help solve the mystery so we can finally both sleep better at night.

And finally you know what is really peeving me off...I have these awesome Delta Vee shocks on my car and I haven't been able to test them one single bit!!! I should just mount one of my Chevy transmission up and fab myself a mounting plate.

Thanks again all for the help. I will post a picture of the old clutch shaft tomorrow after work...I am to lazy to go back outside into the 0 degree garage at the moment.

 

FBB - you hit the nail on the head with what happened to the gear. Basically the nut came loose and the gear started to waggle around which rounded off the splines and chewed the crap out of the gear.

I originally took the gear and shaft to some one I consider to know what the hell they are doing and he was worried about rewelding it and reheating it due to the very little material left on the splines. Its really not a pretty site. My next though was just to weld the gear in place but you cant do that either becuase of the bearing right behind it...so thus I was left searching for parts.

As a side question have you ever looked into the cyro deal for your tranny? I have had it done on some karting motors and other things and its awesome...Diversified Cryo who does Frozen Rotors work is up here in Minnesota and will do it for me if I ask. Just wondering what you thought. They said less friction and in P-cars they have seen 15-20F drops in case temps after races.

 

Yeah and just to finish my venting process if this crap wasnt enough today I arrived home to a nice letter from the IRS requesting I pay them 20k in back taxes for the 2004 tax year because the stupid company I work for reported some sales of options wrong and had them show up with no cost basis thus showing full profit on the sale. So I sat on the phone for 2 hours waiting to talk to the friendly IRS officer to try and straighten things out only to learn I have to make about 20 more phone calls to get all the paper work they need.

When the crap goes wrong it goes wrong....

Whew...now I feel better.

 

Holsteins, Summer Hay and heat cycled shaved tires.

I really hate the documents I seem to get from Ferrari that have crap like this in it. I mean come on they should have clearly pointed this out in the later parts manuals because I have to imagine I am not the first one to have run into this issue.

I mean if the damn workshop manual isnt crappy enough the parts manual just giving people the wrong info is killer.

ah well more updates tonight.

 

So Daniel and I just talked and I am about to call Bruce as well here to try and figure out what the hell to do but I have a question that maybe someone much smarter than me with these stupid things can answer.

Does the gear set that would go on the finer spline clutch shaft pictured below required and equally fine splined pinion shaft and shaft gear? What I am getting at here is if I don't go with Bruce's or another square splined clutch shaft am I hosing myself by thinking that in the world of Ferrari they might have only made the clutch shaft the thinner splines and not equally dicked with the pinion.

The last thing I want to do is get a set of gears that fit this clutch shaft but then would require me to replace the pinion.

All I know is this car is the biggest frankenstien 348 out there now...I have parts from all over the place in this baby.

 

FBB I have a square splined clutch shaft coming from Plugzit tomorrow....well we believe its a square spline shaft but am not sure because he couldnt get the gear off.

If it is a square spline then I am money and dont have to change anything and can go back to the original setup. If its not the square spline setup I dont know what the hell to think.

I cant wait for the UPS man to arrive tomorrow!!!

 

Man I didnt know you were such a ba*tard to Ernie! My favorite trick is to fill the non-sealed bearings with sand and then make people think that they really are suppose to grind.

I got the shaft from Plugzit this morning when UPS delivered through the crappy snow storm we are having up here. I have to get the nut off and then pull everything apart here tonight. BUT just to keep everyone happy here are some pictures of the mythical square splined clutch shaft (yet to be confirmed) and the even more mythical massively multi-splined clutch shaft (aka 145427).
