Twin Plate Orc Thrust Bearing- R32 Gtr

[IOWNU]

Hey guys,

Can I use the standard thrust bearing for an R32 GTR with ORC twin plate?

Reason I ask is because the clutch was working fine, started grinding on take off and would not launch properly (would bog down and yes I know how to launch a GTR.) Intestingly, the car would take off fine if on a slight upward angle (say 20 degrees.) I decided to drop the box.

So the mechanic has replaced the spiggot bearing, but is saying the standard thrust bearing is too short, need an ORC one. Is that right? Or could the issue have just been the spiggot bearing, or something else?

Do I use the standard bearing and hope for the best? What else shoudl we try? I would hate for the grinding on take off to come back, or for the car to bog down on launch again!

Thanks

Ali.

it's usually the other way around? the standard bearing snout is too long. when using aftermarket multi plate clutches you need a shorter bearing carrier. btw the bearins are all the same, it's the bearing carrier that needs a longer or shorter snout.

Do you have the installation manual for the clutch?

The 709d in my car came with a listing of all the nissan part numbers for the throwout bearing and carrier combinations.

Which ones were put in?

nissan have given you a real "gift", there are like 8 different height carriers, 3 different pivot balls and a few different bearings. I use the "datsun" bearing because its the smallest diameter where it touches the fingers, meaning the largest moment arm, therefore less effort needed to actuate the clutch. I then shim the pivot ball to suit what carrier i have (generally can make a 16mm work)
