Installed Twin Plate And Clutch Wont Disengage

[xris]

still not working. put the nismo slave back on and it has throw but not enough to disengage....spoke to anthony from maztech and he said this happens all the time with these clutches. FFFSSS!

so back on goes the 1-1 slave heavy but hopefully this gives that extra bit of throw i need to push in this bad boy...

Sorry for the resurrection but it hasn't been dead for that long..

Anyone know where I can source one of these smaller diameter release bearings/carriers? or have a part number?

Cheers!

Nope still didnt fix the throw problem. have full throw of the slave and it still does not disengage this POS clutch. Now i have to go back to spacing out the Pivot ball to bring it 10mm closer again....hopefully without having to remove the gearbox/engine again... but from past experience i may have to. Possibly look at cutting a hole in the side of the box and retigging it back up when its done...

so i tried spacing the pivot ball and this did not help the clutch now goes into gear but still has issues with the wheels turning while the clutch is in.

anybody with an idea care to give me a clue?

Dude make sure the plates are the right way, if they aren't it WILL NOT disengage properly

hey guys i have this exact clutch, how did you guys fix this issue?? the tuner is finding that itl go into gear with alot of force, and foot to the floor. but its REALLY not nice!

resleeve the slave

extend the pivot point

longer bearing holder

which one fixes the issue??? any further info on you you got it to work would be great!!!!!

Lesson to be learnt from all of this is DO NOT BUY A CLUTCH FROM DCA /Direct Clutch. I ended up sending mine to NPC to asses and let me know what was wrong with it. Apparently the Pressure plate was wrong the teeth were over extending causing the rivets to wear and come loose making it harder to disengage. So i had them fix it for me cost $160 lol.

So now engine is out again and im finally going to get this to work (i gave up on it and went a jap clutch threw it in and it worked straight away) but now i want to push some decent power i need the twin plate

So they have sent it back and asked me to do the following

Measure bearing to bell housing outer currently sitting at - 80mm

Then measure ring gear to top of clutch. - 85mm

Ive also taken a few other measurements like back of engine to top of clutch/teeth when tightened - 75mm

So i'll give the guys at NPC a call today with these details and im sure they will tell me i'll need to buy a new bearing carrier X length so i have X amount of throw for it to work.

Will update this thread once i call them and give them the details.

And for the person who said are the plates backward LOL no they will only fit one way and then on top of that they have stickers saying to flywheel to pressureplate etc. so yeah ive had this thing apart and back together that many times its retarded. i even swapped it for a rb25 box and the guy also had problems with a stock setup so i knew then it wasnt just my setup causing this so gave the box back and now im here again lol

Ok so ive spoken to Doug at NPC and he asked for the following

Bearing Carrier to bellhousing length is 80mm (70mm +10mm for adaptor plate)

Clutch from Block to face - 88mm

Teeth to clutch is 10mm

So we have a throw of 2mm. He told me it needs to have at least 6mm. But suggested i get a bearing carrier 6mm shorter than the one i have atm giving us a throw of 8mm.

So going by these part numbers i'll measure the one i have atm and get the one 6mm (or closest) to that size.

30501-A3800 12mm,

30501-N1601 14mm,

30501-U0200 16mm,

30501-S0200 18mm,

30501-B6000 20mm,

30501-S0160 22mm,

30501-K0404 24mm,

30501-K0510 26mm,

30501-N1600 28mm,

30501-N8400 30mm

So here ends my dcs clutch. worked with the above 6-8mm of throw for 1 lap then the twin plate sound went away. (and yes i had 8mm of throw on the clutch so it didnt over extend)

think i found out why......

lesson to be learnt, use a quality jap brand you can trust.
