Installed Twin Plate Clutch, Wont Release/disengage

[Bliksem]

Hi All,

I installed a twin plate nismo clutch today (along with new spigot, thrust bearing, and pivot ball)

Problem is that when I engage the clutch pedal, the clutch is not fully disengaging/allowing me to select a gear.

Any answers on what could be causing this?

When mine went in there were no probs at all, check everything is installed correctly and go from there

i had that exact same problem with my os giken twin plate clutch.. not to sure how it was fixed but the mechanics did something to the gearbox to modify it.

[T04GTR]

yeah. the box has to come out.. somethings not rite. i suspect the plates are in backwards or something.

[T04GTR]

or the wrong thrust bearing. did you use the big or little one?

[Bliksem]

just used the standard replacement thrust bearing, could that be it?

Definately cant be that the cluch plate is in the wrong way as it only fits one way.

We also noted that the slave cylinder pin was a bit worn... related??

[T04GTR]

yes. the nismo and all other twinplates use the small throwout bearing. off a datsun 1600 if my memory serves me corectly.

cos its the big one it mucked up the pivot point on the pressure plate

[T04GTR]

this is the corect one

[Bliksem]

thankyou for that!

I'll get another bearing sent out. Is the bearing carrier the standard one?

[Bliksem]

ok i'll reword the above,

Those who have a Nismo twin plate, did you reaplce the bearing only or both the carrier and the bearing? (just a bit confused as the picture above shows the carrier AND bearing)

Thanks

Check that your clutch pedal box aint broken. Happened to me. It might of busted the spotwelds on one side.

[Bliksem]

definately wring bearing is the issue mate.

Just trying to work out if i need the carrier to go with the 1600 bearing??

Cheers

nar the carier is the same. but you need to get a back nismo catalogue and see what thickness you need. it is probablyu needs a thinner one. once you get the corect small bearing just see if the clutch fork isnt locked up. it should have abit of play in it.

[Bliksem]

Ok the 1600 Bearing had an outside diameter of 65.45 with the RB25 72.00 (as best as I can remember) the thickness between them was on .5mm difference.

Would the Diameter be enough to change the pivot point on the pressure plate?

[T04GTR]

its height not diameter your refering to. height changes the pivot point.

look, just get the little bearing. put it on your sleeve, bolt up the box, and inspect the freeplay. if it has any.

(min of about 5mm-max-15mm) placing the clutch fork in the forward most half of the hole in the gearbox.

Sorry to revive such an old thread, but can anyone confirm the proper carrier that is used for the Nismo plate in a push configuration? The manual makes no mention of using a reduced height bearing carrier, however I’ve heard more than once that a reduced height bearing carrier is needed, I believe one from a Pulsar or Bluebird, don’t recall. The only component that comes with the clutch is a throw out bearing, which is a standard unit. Thanks for the help
