I spun both wheels, the opposite wheel doesnt move at all. Turned the car on and put it in gear. Both are moving.

I know this isnt the best way to check for LSD...but shouldnt the opposite wheel being spun move?

 

both wheels spin the same way in posi..if it's open...the one spins one direction, while the other spins the opposite. Posi/LSD, both wheels spin in same direction. You are correct to jack it up( both wheels and watch tire rotation.

 

Thing is...I spun each wheel...and nothing happened to the other one.

 

did u just install, or get the motor ? How many miles on the diff/tranny? the more miles, the weaker the springs can be, also this depends on the type of diff used.

 

go lay a patch, see if it's one wheel or two

 

The motor is a jdm b16a from hmotors with less than 50,000 on it. The trans was bought brand new in November and has about 3,000 miles on it.

This has been proven to be inaccurate. My old 89 civic si with a sohc zc swap would lay two strips.

 

damn, brand new... dealership order? ..not sure why it wouldn't spin both tires then.

Yeah, from the dealership.

 

well, you are correct on that, but I just tore apart my ls tranny to put in a lsd unit two weeks ago. I have the open diff in my shop. Like I said before, one side turns one way, the other turns the opposite. The lsd, both sides move in same direction. This tranny hasn't been installed yet, waiting on some motor parts...but this was with the tranny on a bench.

Gear type lsd? That's the way my obx works.

I do not know. whatever the LSD in the USDM ITR trans is.

exactly..there are two types, gear / or cone/clutch type..i'm not too familiar with honda lsds. Either way, both wheels should still spin. The second type needs pressure to active, therefore you should spin one, and the other might not turn.

 

car needed to be in gear for it to work.

car has lsd.

 

Your situation is normal for a helical (ITR) LSD.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Dogginator &raquo;</TD></TR><TR><TD CLASS="quote">Check it like you would check an ITR LSD (from the Helm manual):

Operational Check
Set the parking brake and block the rear wheels.
Raise the front of the vehicle, and support it with
safety stands in the proper locations( see section1 ).
With the engine off, shift the transmissionin to 1st gear,
Rotate either front wheel bv hand and check that
the other wheel rotates in the opposite direction.
lf the opposite front wheel does not rotate, or if vou
cannot spin the front wheels at all, the limited slip
differential is faulty and should be roplaced.

Rotating Torque Check
1. Setting parking brake and block the rear wheels.
2. Raise the front of the vehicle, and support it with
safety stands in proper locations( see section1 ).
3. With the engine off, shift the transmission into
Neutral.
4. Measure the rotating torque with a beam-type
torque wrench in the direction shown (top towards the rear of the car), Rotate the
torque wrench more than two complete turns and
take the maximum reading.
5. Shift the transmission into 1st gear and measure
the rotating torque again.
6. Calculate the rotating torque:
Service Limit:
(Measurement from step 5)/(Measurement from step 4) &gt;=2.5

7. Repeat steps 3 through 6 for the other wheel.</TD></TR></TABLE>

another member JUST posted that about 10 minutes ago. I was testing with it neutral. Put it in 1st and no problems.

thanks for finding the link though.
