Hey peoples, my clutch is up for sale... it was going to modified for use in my GTR, but having recently bought a house, the whole GTR project has gone down the crapper (or at least put on hold for a year or more).

As such, I'm selling off bits and pieces which have just been sitting in the cupboard for 6+months... no point in keeping them around, for a project that may actually never see the light of day.

So, my clutch is for sale. Got this off a mate about 6-8 months ago... it's *ultra* light, weighing in at 4.5kg, and is only 7.25" in diamter (185mm). Put simply, it's tiny, with a tiny rotating mass.

The clutch uses sintered metallic discs (3x), and I have measured all disc thicknesses, with all coming in at 0.102" thick. Brand new these clutches are 0.104" thick.

Taken from tilton's site:

Clutch discs start new at .104" thick. Discs should be replaced when total pack wears .030".

This means the individual disc thickness should not be less than:

• Single disc = .074" • Two disc = .089"

• Three disc = .094" • Four disc = .097"

The friction material used on these discs is extremely wear resistant. It will typically wear

quickly for the first .002" of disc thickness, and then wear dramatically slower after that.

As you can see, the clutch is in great nick, having only worn 0.002" on each plate (which will wear quickly), and each plate has another 0.008" of useable wear (which will wear slowler than the previous 0.002").

Clutch plates are 29 spline, 1 1/4"... I was going to have it re-splined for GTR use, but as stated before, I've bought a house, and the interest rates (up until just lately) have been f**king me in the ass, put simply, and I can't afford to do the project right now. Brand new clutch plate packs can also be sourced from tilton quite cheaply in multiple spline/teeth and size, for chevy's, supra's etc. As an indication of cost, I asked a local aus dealer for tilton on a price quote for 3 brand new clutch plates, suit RB's / GTR (24x 1"). Total cost was $544.50 inc GST, that was from Earl's Australia (the fittings guys).

Still waiting on a response from Xtreme clutch, they're also dealer for tilton here in aus...

As for the exact torque holding capacity, I'm not 100% certain on. Minimum torque holding capacity for a Tilton OT-II triple plate is 612nm (450lb-ft), while maximum is 1713nm (1260lb-ft). Looking on the diaphragm,I can only see the stamping "G", of which they offer two models - HG and UG (H referring to high for the pressure plate ratio, and U for ultra-high). The specs on these are 1266nm and 1509nm respectively. Again, I can't be 100% on this, however, the person I did buy it off is running an identical clutch to this behind his rebuilt 1UZ-FE (turbo... t88-34D) powered supra... he was putting down in excess of 500rwhp on 12-13psi. His original OS Giken twin plate (from memory rated to "700hp") slipped horribly, to the extent that the clutch plates fused onto the floater plates. He's had no issue with the tilton so far... (no surprise there).

The clutch uses UN-SPRUNG discs with a push-type release bearing, and is similar to drive like that of a HKS unsprung triple...

These clutches are also individually balanced and marked from the factory.

If there's anything else you want to know, just ask

Asking $550, however this is negotiable, I need the money hey... If postage isn't too much, i'll throw it in for free.

Cheers,

Christian
