Just short shift, in the future.....wow, to the parts cost, but no surprise. Go check out the F40LM resto thread, his REVERSE gear was trashed (WTF??, How does THAT happen?) ) and he had to have a new one 'cut'...none available, in the world. These are rather special cars, compared to Chevrolet.
this gearbox has been already in the 365 GT4/BB, so now 40 years old. at that time more than up to date technic
the speed of shifting has nothing to do with the wear of the gears, only the extreme acceleration is bad for the gears. so you may use only good synthetic oil there are some gears manufacturer that can make them, also for a F40, gear is gear, you only need very high quality material like for example 18 Cr Ni Mo 7-6, but you have to heat-treated it before use. also I think this would be cheaper then buying from F. they even are not doing those by themselve. most comes from ZF what please means WTF ?
It means "scratching your head in wonder" Literal translation is "What, the ^$%^%%!!!" A curse of sudden ill temper, using some bad words... It's a common computer abbreviation, among the English speaking young ones, I have three children.
but then only a teenager with english as home- or mother language and those are not around at my place here
I've been away dealing with Honda issues. Ouch - right (And some Aweful frustrating Ferrari stuff - not really the fault of the car - more like old age meets uncompromising cool Italian sports car). I see you got it apart! Way to go. You did make it look EZ, and you were very kind to the hardware. Love the use of the license plate! The mainshaft locking groove issue I mentioned a couple of pages ago was I used a caefully ground chisel to surgically uncrimp the ring nut, and I didn't clear it 100%. I figured the tiny interference wouldn't be an issue given the ultra hard and tough steel those trans parts are made of. Anyway - it caused an ever so tiny chip in the edge of the locking groove. Not enough to hinder retention or compromise any strength or functional properties of the shaft, but I was bummed none-the-less! I also wanted to suggest GT care parts for possible shims. Bill Young is a pretty talented and enthusiastic Ferrari guy who knows parts well and sells them for sub-stratospheric prices. 623-780-2200. If you talk with him, I think you'll find more great support along with the buds on this site. Fingers crossed for you.
Ahhhh, so nice to have so much support and input here. You guys rock. (Romano, that means you're good.) Wecome back Mr. 2dinos. Don't ya just hate working on any car other than your B*tch? I have John from Trutlands trying to find the shim for me now. If no luck, I will go to my local bearing house! (Wild! They're on Maui yet they have every bearing imaginable. SKF, Timken, you name it. Maguire Bearing Co. I never tell them it's for a Ferrari and they never charge me the Ferrari prices ) Hopefully they can help me find the shim. As a last resort I will have to make it along with the RHS cover shim. Shouldn't be a big deal since it's just round. Ya, I can grind a notch. No big deal.
OK, now for an assembly question: I can't seem to figure out the answer on this after reading the WSM over and over. If I change the shim on the pinion, is it going to cause stuff on the layshaft to move requiring me to re-shim it or the mainshaft? Or does the pinion shim not have an affect on that. From the way I look at it, there should be no change. Am I wrong?
lol my former girlfriend often told me the same to your other question: the mainshaft has absolutely nothing to do with the pinion shaft for adjusting this pinion shaft. when you put in thinner shims for the pinion shaft ( no 21 on table 33 ) then you have to put in thicker shims ( no. 8 table 33 ). but before you start shimming you may check the preload ( bias ) of the bearing no 19 and 23 table 33.
Just got an email from John at Trutlands. He doesn't have either shim. That's bad. The pinion shim isn't a problem but this shim is a big problem. I don't see fabricating it. Guess I'll keep looking. Image Unavailable, Please Login
It's near impossible to remove that mainshaft nut without buggering up the shaft - take a look. As you said, it's not pretty but it won't hinder the new crimp. I just called your guys and they will have to go dig for the shims I need. I don't expect to hear back from them but I'll be grateful if I do. This layshaft shim is turning out to be a real pain in the .... Image Unavailable, Please Login
no scott, I mean table 33, no 8 and 21, if you mean the preload shims Image Unavailable, Please Login
this shaft looks not so bad scott. don´t worry ! ! ! the shim is a really great problem. but you need a thicker shim when the end shim of the pinion gets smaller. so as soon as you have the smaller shim you put the pinion in and adjust the preload with this original shim. then you take a feeler gauge and meassure the size you need. it is not a need to use a shim exact the size you need. you also could put in a normal shim with the additional size you need.. so you have then 2 shims inside, but that is not a problem. only problem is to get them in good luck again
AAAARRRRGGGHHH!!! Ferrari standard practice=no longer produce the parts I need. #8 in the list. I'm looking for thicknesses 6.1mm and 6.2mm part numbers 110178 and 110179 respectively. Guess what?? Ferrari only makes 5.9, 6.0, 6.3, 6.4, and up. It's as if they knew I was going to go through this and need exactly those shims. By the way, some dealers show these part numbers to be the same shim only different thicknesses. In fact, the 110178 comes up as a 6.5mm and 110179 comes up as a 7.0mm BE CAREFUL IF YOU HAVE TO ORDER THIS! Overheard in the Ferrari factory lunchroom - "Hey remember that gearbox I built in 1988 that the C&P were shimmed wrong?? I bet that owner is trying to fix it now because those diffs are breaking right and left. We should stop producing the correct shims just to mess with him" (((Evil italian laughter))) So me and my machinist are going to be good friends real soon. Gotta buy a 6.3 and have it cut...what a cluster...
Scott, I'm retired now, but when I was a working machinist I could make that shim. You should be able to get it machined. Ago
Ya, I'm going to just buy the 6.3mm and have it machined. Why don't you come out of retirement and do some charity work!
