Hey Guys, so been busy working on my project and I installed the Quaife over the weekend but am having a pretty big problem. I put the Quiafe together with the 3.84 ring and the speedo gear and the new bearings. I installed the new bearing cups and the Quaife had some play so I got the SMALLEST shim that I had in shim pack which I measured at .040", put it in, bolted up the tranny, torqued it down. And it wouldn't spin what-so-ever. So I took it apart and one of the bearings had not fully seated for some reason, bottomed it out, bolted it in, and it spun like butter even with the bearings dry. I measured about .003" of side play in the differential, and was happy with that since I don't want it to bind up when things start to heat up.

So, happy with that I bolted in the input and output shafts and my new fangled shift forks and put it back together along with putting some ATF on everything. Didn't fill it up, but enough lube for testing.

After putting in the input and output shafts though I now have a problem. I can spin the input and output shafts no problem by hand when the tranny is in neutral, but if I engage a gear with the shift tower. Everything binds up. So no having the spline socket, I put my clutch disk on there for a little more leverage and got it to spin, albeit grudgingly. And, when it does spin, there is a DEFINITE clicking/thunking/binding sound between the differential and the output shaft, and it spins in "steps" as though it's binding between gear teeth.

Is it possible that the 3.84 gear is binding up with the output shaft? Anyone have a similar problem. Also, on a side note, there was a shim already on one of the differential bearing cups, that although I didn't measure, would guess to be around .025", which of course, I lost somewhere in the trash.
Help me out here guys, please. Thanks a million.

I know nothing of transmissions, but I hope you get that worked out, bro.

Good luck!

Refresh My Memory...Did The 3.84 Gear Come Out Of The Zetec Tranny??? If So It Seems Odd That You Would Have A Problem There, Many People Are Running The Zetec Final Drive W/O Problems Of This Nature...It Is Still Seeming That Your Shims May Be A Bit Out Of Skew...Or Possibly That One Of The Press-Fit Bearings Is Hanging Up Or Not Seating Properly...I Did Not Personally Install My Quaife (Shimming Scares Me On A Part As Vital As A Differential) But I Watched Mine Being Done And It Did Take The Technician A Few Times To Get The Shims To The Correct Tolerances...But The End Result Was No Endplay and my axles spun freely with no Problems...But Again I Am Not Using That Ring Gear....
Not Sure If This Helps Any But Hopefully Brings To Your Attention An Oversight Or Idea Of The Problem!!!

this is the reason i got the torsen from keith at streetflight. he already pressed the bearing and speedo gear on...i did'nt have to find a shim kit...and i was, to tell you the truth, scared to mess with the shims. I am not a very experienced mechanic but i did'nt have the money to pay anyone to fix my tranny. I guess experience is needed as long as you do it right...cause she's still runnin(as far as the diff. install goes!) Good luck with your problem!

hey guys here is what terry told me on the deal with the zetec gearing...

You need TWO gears to change an FDR..the ring gear(it gets smaller less teeth)AND the new OUTPUT SHAFT AND GEAR...that gear gets BIGGER..trying to make a Zetec ring gear mesh
with a V6 output pinion ..won't work wrong size,wrong
teeth count,wrong teeth pitch!...you need TWO gears to change an FDR on an MTX75 NOT JUST THE BLOODY RING
GEAR!...Have a good day!!! TH

so i would take terrys word for it. the brit knows his transmission.
