Jonathan, Take a look at this post from the archives: http://www.ferrarichat.com/discus/messages/256120/8258.html It could account for those washers that BSC found between your pressure plate & flywheel! | ||

Guys, I actually enjoy spending the small amount of money I have on the Ferrari. I trust me as a failed musician I am sure that I am one of the least able to do this BTW. It has given me so much enjoyment I treat it as well as my wife! :-) Love must be blind!!!! John, I always use new nuts on a project but if you tap in the installed one correctly with a chisel at each side of the slot it is not going anywhere! :-) It took me about 2 hours to get my original one off and I think I messed up about 4 different tools!!!! Although I cannot disagree with erring on the side of caution. John, Glad everything is back and working, I took dozens of photos of this and other gt4 projects if anyone needs any specific photos let me know and I will look to see if I have one! Aren't digital cameras great!!!! Rob | ||

Cheap skates?? Na. Just enjoying a challenge not to be gouged $80 for a socket. I did it too. THe only thing I did buy was the 4 sprong socket for the timing gear. I could not make one. | ||

I may be the world's most arrogant cheapskate (a dangerous combination if you own a Ferrari), but I made a tool to remove/reinstall this nut. I bought an S-K 1-3/8 1/2in drive socket (P/N 40144) for about $5, then went to work on it with a disk grinder and a file. It's worked fine every time I've used it, including torqueing the nut. Please excuse the picture - cheap camera (see above).  | ||

Lock-tite is just a precaution- you do not want this nut to loosen up over time. With a new ring nut, you should be fine. It's just extra precaution. If it can't hurt, I will usually do it. I just finished my clutch on a 84 QV and was told this info after I put it all back together. I used the old nut and no locktite. I'm now ordering the new nut and will pull the transfer case again and replace. Just piece of mind. It will only take an hour or so now that I've done it once. Buying the Baum tool really helped. Worked perfectly. Robert- thanks for the email last week. I replaced the clutch, throw/out, pilot, pp, and o-rings. The noise is now gone. My clutch was not in dire need of replacing, but it's new now. | ||

Thanks. You are making the job a bit easier. I am actually going to try to mill the new nut to a standard hex so I can use a regular socket. Even if I paid someone to do it, it would cost less than buying the special tool from Baum. Jay | ||

jay, you do not need loctite as the castle nut is retained in position by the deforming of its rim into the slots in the transmission input shaft. rob  | ||

You might want to check that you have the retrofitted (several years ago) snap ring retainer. The original (P/N 105141) was replaced (I don't have the new part #). The original was flat on both sides, the replacement is like a flat cup, where the edges cover and retain the snap ring (P/N 105138). The assembly sequence is (1) snap ring; (2) snap ring retainer - cup side in, over the snap ring; (3) bearing (4) Lower transfer gear (5) castle nut. The part numbers for the parts you may want to consider replacing are: 105138 inner snap ring ??? new style snap ring retainer 11061075 outer snap ring 105137 castle nut | ||

Malcolm is right. Also- I've just been told by a Ferrari mechanic to always replace that lower gear nut and use a little red lock-tite on it. Try http://www.cameragear.com/ec/clutch.htm for a procedure. My $.02 | ||

Jay - correct you donot need to undo the top nut, however they are known to come loose especialy if the nut has been removed and not tightened up with the correct tool so it's worth checking. When re-assembling don't forget to put a small amount of oil in drop gear casing. MW | ||

It appears that I only need to remove the special nut from the lowest "drop gear". At some point in this cars life, the upper nut (actual clutch input shaft) has been removed. I don't believe that was necessary. I could not find a good procedure on this, the 308 FAQ is a bit vague on this subject. Any other write ups on this? Thanks, Jay |
