Who's using a limited slip?, Anybody got one.............. Options

They list one for the 915..  should be the same...

they are probably not aware that 901s and 915 use some of the same components.

QUOTE (Mueller @ Feb 6 2006, 10:37 AM) Rick, I took apart a good working 901 transmission just for the diff. to send to Phantom (not directly, thru that kid that lived in the desert that had 924's that Sammy is pissed off at for stiffing him on a radio) According to Phantom, no dice, they couldn't make one to work and on top of that, wouldn't return the diff..... That's wierd.. (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) They list one for the 915.. (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) should be the same...

dunno, maybe the guy lied to me, I had been told I would get a Phantom diff at cost or less if I supplied the parts for R&D...once he said no dice I left it at that and didn't question anyone about it....

I have a 915 ZF limited slip in my 901 (914-6) gearbox.
You need the entire ring gear carrier, and output flanges form the 915. This mates up with 911 (6 bolt ) inner CV joints. These CV joints have to be taken appart and the ineer ball (spline) section shortened so that it will fit on the 914-6 half shaft spline. Actually using the 911/915 ring gear carrier (901 ring gear bolts right up) off-sets the output flanges by about 10mm. But due to designed in axial in the CV joints, this is no problem. I use Swepco 201 and use a (bilge) pump and tranny oil cooler when om track. The limited slip is preloaded at "80%".
Works very well on the track, in that when in the turn, letting off slightly on the thottle will tighten up the line. all in a very controlable manner. The motor is a hot 2.4 S. I was pleased with the result and teh used 915 ZF was a lot easier to find and less expensive.

Ok, one more time on this thing, Does anyone know if the 901 and 915 OPEN diff use the same carrier?

Q. 1) Can some check part numbers?

Q. 2) Does anyone have both units apart in there shop?

This is what I'm looking for.


Q. 3) I need to know if the space between the spyder gears is the same.


Q. 4) And if the spyder shaft is the same diameter.

I doubt it.. I have a 914 carrier on the bench at home, and it has a 914 part number. I can post it when I get home.

I suspect the phantom grip will work in a 914 trans, but only if a 915 carrier is used.

How much does a 915 ZF cost?

What pump are you using? I've set up my 901 for a cooler but I have yet to source an affordable (but sufficient) pump. I've been thinking of a convertible top hydraulic pump, but I'm a little worried that they aren't capable of continuous duty.

When you say "offsets the output flanges by about 10mm", do you mean the output flanges end up 10mm farther apart, effectively making the ideal axle length shorter?

I guess that's why the second part of the question.

If the shaft is the same diameter, and the spacing between the gears is the same, the carrier won't matter.

I'm attempting to save the cost of setting up a different (915) carrier in my case.

Ok, well I'll get you the measurements and part number that I can, and hopefully someone with a 915 can cover that side of things.

Thanks,

I think I'll start a new thread to get some more attension. (IMG:http://www.914world.com/bbs2/html/emoticons/mgw.gif)
