Hey Mark, How did you get the little black horseys to stumble into & leap out of the gears (:P) LOL? | ||

Thanks Mark, can I trouble you for one more of the bottom of the nut, in other words the part that come into contact with the gear. Thanks! | ||

Hi Jay, They both look similar in design (both have a collar) but the overall depth of #106095 is 13.15mm and the overall depth of #125534 is 17.15mm. I would post pictures but our camera is broken at the moment. Best Mark | ||

Mark, what is the difference between the two nuts? Does one have a "collar" on it or are they both "flush"? | ||

Thanks Mark, but I have both shafts and neither one allows the nut to be tightened sufficiently. Are there two part numbers for the nut? | ||

>>>For Driving Gear #119721 is for use with Clutch Shaft #109400 For Driving Gear #125531 is for use with Clutch Shaft #125532 << This makes sense now why the gear/shaft/nut problem exists. For some reason the dimensions were changed between the two sets. Thanks Mark, another mystery solved (partially). | ||

Our system is showing that it only fits a QV. No record of it being on a TR. Clutch Shaft #125532 was to be used on exhaustion of Clutch Shaft #109400 | ||

so Mark 125531 is also from a QV? | ||

No there was no shim. I even took the QV bell housing and shaft and tried putting the gear back in it's original place...there is still slack between the gear and the nut on the original case! I had visions of simply changing the bell housing, but to no avail. It seems that Someone was driving around with a loose transfer gear all that time! I really don't want to make a shim but it is begining to look like I will have to. I am not spending $1000 Canadian for a gear! | ||

Jay, Since you saw the set of gears come out of a QV, I'd guess that there was a ~3mm washer shimming this particular gear up to std width. Any chance it's still lying around where you got the gears? | ||

You wouldn't happen to have a 119721 lying around would you?  | ||

Jay, glad you found the problem and thanks for "the heads up" on this gear/shaft re-marking issue. I'll definately file this info away in case I run across this prob lem in the future. Regards, JRV | ||

Found out the problem, you guys are gonna love this one! It appears that Ferrari ran out of #125531 gears. They are identical to the QV gear with one exception. The "hub" is taller (about 3mm) on the QV gear and shallower on the TR gear. I'm talking about were the nut seats itself against the gear. I guess they shaved it down at the factory and rebadged the # for the newer car. I now have to either make a spacer or find a new top gear #119721. I tried using the TR nut but it is a different thread and is of the same style as the QV nut, so that won't work. I only found this out by comparing my gear with a friends QV gear. You gotta love hand made cars! | ||

Here's the top gear on my 83 euro 308 if it helps. I never removed it for the clutch job- but the other two are 119722, and 119723 just like you wrote.  | ||

Jay, are you sure you have the face of the gear on the correct side? There is a bearing side and a nut side. Is it possible to post a pic? | ||

There are differences in the shaft. On the QV shaft it allows the gear to seat further down, leaving even more space between the end of the threads and the gear maybe a 1/4". The GT4 shaft leaves much less space maybe 1/8". I've talked to several others who have done the update without any problems, just this extra part number on the top gear is throwing me for a loop! | ||

Wow...Jay...honestly I never tried to compare the two to see if there are differences...but I'll take your experience here as validation there is. Truthfully the vast majority of the time I just tell my parts guys year and model and they handle the details. A good start would be to call the guys at Algar in the morning and have them cross everything over for you and maybe even pick the bins and spec out any differences so they can get you headed back in the right direction.

Okay, a few months back I was asking about interchanging transfer gears on a GT4. I've since purchased a set of QV gears part #'s 119721,119722,119723. I also got the QV input shaft. After putting it all together the nut #106095 (same for QV and GT4) runs out of thread on the shaft before it can tighten up on the gear. Upon closer inspection I noticed that the top gear #119721 has it's original number sanded down and a new number #125531 scribed onto it. I know that all 3 gears came out of a QV because I watched them come out. They were all in the transfer case together. I've been told that #125531 is a transfer gear for a TR but I can't confirm this. My question is this...Are the TR and 308 gears the same? If it is in fact a TR gear will the TR nut hold down the gear? I remember the nut looking different when they were removed but it was damaged and thrown away upon removal. Any help would be appreciated. |
