Throw Out Bearing Carrier Dimensions

[GTR1993]

Hey, i bought a few GTR boxes (push) and some sr boxes, thanks to the importers they gave me a heap od forks and carriers that "should fit" haha, its ok as they were cheap. Anyway, does anyone have heights of the GTR carriers so i can identify the right one, or can i use anyone with the correct height bearing? I'm converting my GTR from an extreme twin plate pull clutch to a push gearbox with a nice sprung center Blitz clutch, does anyone know the dimensions of the bearing i am meant to use with this?

Thank you

cool. well 99.9% of multi plate clutches all use the 12-14mm carrier. mesured from the base of where the bearing sits on it to the surface the fork rubs on

no idea what car they come from..

ps.. you must use the small "datsun" bearing. (the standard one is wrong for a multiplate., a very common mistake)

they go right up to 25mm or so for the stock clutches.

thank you, i have found on the ORC site a PDF with all the nissan numbers with there respective measurements! Also i went to a reputable clutch place here and bought a small throw out bearing as you described its very thin. I just ordered a new push slave cylinder to suit the new g box and ill dummy it up and take some measurements and see where im at, but it looks good to go atm.

Thanks

cool just so long as the fork is in the front half of the hole in the gearbox youl be ok.

oh, make sure its got the long pivot ball on the box..

yo

just having a read threw here.

about to put my 30det and 25t box together with a nismo twin plate clutch.

measured up my throw out bearing carrier and mine is more like 22mm???

and im unsure if its the factory throw out bearing.

it came with the clutch kit that was brought brand new from a private seller..

how do you go about getting the smaller throw out bearing carrier and such

cheers tom

well it all depends, what i did was use a 16mm carrier with a 16 mm bearing (small usually like 22ish) then it was a little bit too small, so i spaced the pivot ball out 2mm. You can change pivot ball spacing, bearing and carrier.

goto nengun, they have the ORC bearings and a link to the ORC web site, on the last or 2nd to last page of the catalogue it has all nissan part numbers for the carriers. I just ordered a brand new nissan 14mm carrier and dont need it so if u want it i will sell to u for what ever it cost me (they week wait special order from japan)

is the 14mm carrier a must have with the twin plate clutch??

i have a kts strenghened pivot ball in their aswell if thats relavant

[GTR1993]

u do need a smaller one, most i have for sr20s etc is the 22 mm carrier i think its heaps too big. I dunno the size of the KTS pivot to advise.

[T04GTR]

the ball, short is a 14mm bar with a ball on it. the lon one is just longer. like 30mm or so. make sure you use locktite on the ball as it will leak oil if you dont.

of and the bearing is heaps smaller in diameter ie: the rubbing surfave is just bigger than the sleeve its pressed onto. where the stock one is alot bigger.

nismo use the small one.. youd be supprised how many people sell there twin plates because its to hard to drive....all because they have wrong bearing. nismo also needs a 16mm~ carrier. i used a 12mm one with my g-max3.
