Hey.
I just had my motor out to install a new headgasket and arp headstuds, and also to install an ACT clutch, ACT pressure plate, and ITR flywheel.

Before I put the motor back in the car and after I put the tranny back on, the motor would turn fine from the crank pulley. Now its back in the car and ready to be started, but theres a big problem. I have a stock JDM B16 tranny with an LSD, and before I could spin the tires effortlessley when it was on the lift, but now I can HARDLY move them at all, and the little bit that I can force to move causes the tires to spin in OPPOSITE directions, which as you know on an LSD tranny the wheels spin the SAME direction.

The clutch feels good and firm and when I push the clutch in, the tires spin like normal in the SAME direction just like they should when the clutch pedal is out.


What could possibly be wrong? Everything is torqued to spec and this is depressing because its my daily driver and its totally hooked up ready to start for the first time in 2 weeks. ANY help whatsoever is greatly appreciated, it took me and a buddy about 30 minutes to line up the tranny when it was on the ground and I really am not looking forward to pullying it off or pulling the motor again

Cliftnotes: After clutch and flywheel install, tires do not rotate hardly at all, and when they do they spin in opposite direction (this is wrong b/c of LSD), but they rotate in the same direction when the clutch is engaged.

Thanks

 

no one has any idea?

 

I read thru that a couple times, but I'm not sure I understand what's wrong...

When the transmission is in neutral, you should be able to spin the wheels, and the opposite one will spin the same way. Just the same way as when you have the clutch pedal down. (You know you press the pedal down to DISengage, right?) So far that sounds normal.

Now with the transmission in gear, and the clutch engaged (pedal UP)... There should be resistance when you try to spin a wheel. The opposite wheel should turn the opposite direction. Just like with an open diff, except for all that resistance. After all, it's still a differential... all that resistance is from the LSD.

So what's not right?

 

Thanks for replying, I appreciate your time.

Its really interesting and I've been giving it thought today and I do think I might just be retarded.

But here's what is still questionable about it... I could always turn the motor fairly effortlessly with just 19mm socket and 1 ft wrench, but even if it is in gear, and the tires off the ground, does it make sense that I can hardly budge the tires when pulling on them, and that if the car's in gear I cant push it even an inch?

Actually, Im thinking as I write this (good thing right?! heh) and **** I used to never use the e-break and just leave the car in gear on hills and I never had it move.

Also, I always thought that regardless of what the active gear was, the LSD caused both wheels to spin in the same direction. Thanks for clarifing that

hmmm, interesting, I'll bolt up the shift linkage first thing after school tonight and put it in neutral because I do remember pushing in the part the shift linkage connects to when the tranny was off the motor.

Thanks and now feel stupid because I made this topic at 3am after a full school day and 8 hours of working on the car so I was tired as hell and not thinking right.

 

It's a lot easier to turn the crank when the spark plugs are removed. Maybe you're remembering that?

When you park on a hill, I bet it'll hold if you're in 1st, but it'll roll down if you park it in 5th...
