how do you retain output shafts in torsen

[Marshall Grice]

I'm curious how most people retain the output shafts in the diff. We used the brake rotors before...kinda don't want to do that again. We were thinking something like a c clip but it doesn't look like there's much space for that.

We used a retaining clip similar to what the inboard cvs on an atv use, you taper the torsen splines so it compresses then pops back open once the shaft is thru, kinda of a PITA to get them out at times. brake rotors sounds like a good idea if your running duel inboards. How are you attaching the rotors to your shafts?

[Marshall Grice]

did you actually have to machine the gears on the torsen or are they already tapered?

We are running dual inboard rear brakes. the rotors were bolted to the inboard tripod housing and the float came from the output shaft moving in and out of the torsen. it seems to work quite well on the long side output shaft but the short side is a different story.

I don't use anything to hold the output shafts in. We put a stiff spring in the axle for plunge that doubles for holding the output shafts in. I've done it this way for 3 years and haven't ever had a problem with it.

two words...

"duct tape"

Hey Marshall,
Hope the car is going well. I bet you guys are way further along than us. We have always used c-clips to locate the output shafts in our bearing carriers which are bolted to the chassis so it pulls double duty.

We used a spring to hold the stub shafts in. It was a modified version of the tayler race setup. We havent had any problems with it.

We have used simply the press-fits between the bearings and stub shafts to hold them in. It works well as long as you can machine to a decent tolerance. It also helps that we have dual inboard brakes that would hold them in were the press-fit to fail. For those of you who use the springs, do you do this in addition to press-fits?

circlips. more than enough room.

We have a slip fit into the diff. We are using the Tayler tripods inboard and outboard so even if we used a press fit or a circlip we would still have to keep the halfshafts from moving axialy. Using a spring holds both the halfshafts and stubshafts in place. It is realy easy to assemble and disassemble as well.

We do use circlips to keep the stubshafts from going too far into the diff though. This prevents the possibility of one shaft engaging both side gears in the Torsen.

We didn't do any testing to see how much the stubshafts move while driving but so far we havent had any problems.

well cool. thanks for all the replies. time to go come up with something now...

So your diff becomes locked... Great for acceleration. http://fsae.com/groupee_common/emoticons/icon_smile.gif
