Quaife LSD - help?

[Mr. Win]

yea i checked the manuals and didnt see s*** for him... he picked 32 as a guess so hes all good.

 

[Kooldino]

Yeah, I decided on 32 right before I noticed that you left me a message. Great minds think alike.

So i have good news and bad news.

The good news - The car is up and running, and it grips like hell. I still have wheelhop, but oh well. The straights are great and the turns are even better.

When the two front wheels were off the ground, I spun one forward and the other one moved forward with it.

The bad news - About 15 minutes before we were finished, I noticed a shim that goes under a race sitting off to the side of the garage floor. Anatoly had found it a little while before. Apparently, this fell out of the trans when one of the races fell out. I think it's one of the races that holds the diff in place, but I forget.

Am I screwed now? Is my tranny gonna explode in a week? I'll have it measured tomorrow, but if I had to guess, I'd say that it was 8 thou or so.

 

[Kooldino]

Idea: If the shim does in fact go into the driver's side of the diff, perhaps I can pull all of the 14mm bolts off the the trans that holds the two halves together IN the car and do it that way? Is that possible?

 

[LinuxRacr]

Oh damn, I hope it works out for you. That would be bad news!

 

[Focus]

Don't take a chance. Pull the tranny out and re-do it.

[CustomMSP]

I'm pretty sure that shim was behind the main gear shaft race that sits behind fifth gear. It looks to small for the diff. race.

 

[Kooldino]

I just had it measured. It's 22 thou. That sounds like a lot.

 

[TurfBurn]

22 thou is quite a bit.... a crank bearing clearance is about 1.9-2.2 thou.... thrust allowance on the crank is about 5 thou if I remember right... turbo end play is usually supposed to be under 10 thou... so how that fits out to the tranmission I don't know... but as you can see compared to other instances it is a fair amount.

Yeah, I'm thinking the same thing. I'm really worried now.

If we have to do this again, I might just kill a few birds with one stone.

1-replace this thing
2-change my clutch (The 6 puck is too harsh for stop and go traffic every day)
3-Make a trans cooler.

 

[TurfBurn]

I've been happy with the Spec Stage 3 ST3+ disc combined with my ACT pressure plate... so that's been good and is super streetable.. hasn't slipped at all yet either.... granted I"m only at about 260 at the wheels.. but that's decent...

I have the cooling system all designed up, I need to figure out if i can do one part a lot easier, but otherwise it is done... and I'll have a version of it on my car in the next few weeks once I get these last other gremlins (oil and water issues) taken care of.

Later!

[Kooldino]

Ok, I put the 22 thou shim back behind the race, but I can spin the race inside the trans housing. Is that ok? If not, how do I fix it? Could I put rtv behind it?

 

[TurfBurn]

yeah... the races spin... so don't worry about that... I wouldn't put the RTV behind... but when seated some of them still spin... no worries there.

 

[Kooldino]

Ok, phew.

Well, we got it all together in enough time to make it (late) to yesterday's meet...I have a few hundred miles of break-in to go on the clutch.

 

[CustomMSP]

Which clutch did you get again? Do you feel any difference in the way the tranny shifts/drives?

 

[Kooldino]

I got the hybrid. I think it's actually called the stage 2 hybrid, but people call it the stage 3 hybrid? Either way, it's a 6 puck on one side, and a full face on the other.

 

[TurfBurn]

Yeah... you have the ST2+ disc... which everyone on here calls the Stage 3 Hybrid... but it is actually a hybrid of the stage 2 and the stage 3... the actual stage 3 "hybrid" or ST3+ isn't really a hybrid at all, it is a full face solid ceramic sprung disc and is the single most expensive disc that Spec has, and is what I run... The disc alone costs more then 350 dollars... WITHOUT a pressure plate! And that one is called the ST3+ disc.

Glad the disc made it in time and so forth... I'll see if they sent the final shipping bill through to me now, and I'll get you that final total Dana.

thanks!

Did you keep the old Spec P.P.?

 

[DiS]

Did you keep the old Spec P.P.?

Im 99% sure that Dana kept the old spec p.p. on there, as I was doing something along with dozing off (falling asleep) while Dana was putting clutch back together while trying to wake me up numerous times, lol.

 

[Kooldino]

Yeah, kept the PP and had it "remachined".

 

[DiS]

Yeah, kept the PP and had it "remachined".

yea lol "remachined" haha. My half ass job while i was dozing off and you took over.
