Jap spec TT clutch info

Recommended Posts

I am looking into getting a new OE clutch for my jap import Supra TT '93

 

I have been told buy a couple of places that the jap spec has a twin plate clutch as standard and for a patent part clutch its nearly £900!!!! :confused:

 

What I need to know is....It the jap spec clutch same as the UK spec? Where is the best place to order it from and do I need to get anything else too? Something i remember reading tells me the flywheel needs something changing too?

 

Thanks for your help guys!!! :)

Thankyou very much for your replay mate

 

So, knowing that i can order any clutch UK or jap spec, Do I also need to order the bearing that goes in the flywheel too? and if I order a clutch kit from Toyota that comes with the release bearing and spring plate too?

 

Sorry for so many questions newbie and all that! and I know I should :rtfm: :read:

 

Thanks again for any replies

Tell them they are talking rot mate

 

When i had my J-Spec TT a couple years back, the clutch went, i got a standard clutch plate, cover and release bearing all from Toyota and it wasnt more than £200 i dont think. I think it was like £180 odd but cant remember now. I certainly remember being pleasantly surprised at the price though :)

 

My flywheel had a "heat spot" on it when i went to change the clutch but as i was selling the car i didnt bother with the flywheel. I think u only need to do that if its badly worn / scraped or distorted out of shape.

I do an uprated, direct bolt in replacement for Jap and UK TT clutches, see below:

 

Available now: Uprated MKIV TT clutches.

 

I have instigated a few new performance parts for the MKIV

Supra TT's. I will announce when things become available,

but one which is available NOW is an uprated clutch assembly.

I use the stock, brand new driven plate, as it is correctly

balanced, doesn't judder and will hold all but mega torque

highly modded engines or cars used for drag racing.

I modify a stock brand new cover to give more clamping force.

The reason I tooled up to do these is some of the aftermarket

US clutches I have fitted SEEM to be built from used cover

assemblies with reground friction surfaces, and a stronger

spring. I have had hellish trouble getting these to fully

release, because due to this seemingly thinner cast iron

friction face, the geometry of the clutch goes to pot, and

being a pull type clutch (the hydraulics pull the bearing

away from the engine, rather than the more normal push type)

it is a lot harder to effect a cure.

 

For 425 pounds, no VAT to pay, you get a brand new driven

plate, a brand new modded cover, and a brand new release

bearing. I would rather fit myself so any complaints are down

to me, I see too many clutches juddering due to someone without

the right gear allowing the gearbox input shaft to bend the driven

plateas the boxes' weight is allowed to swing on the plate centre,

or clutches fitted to patently buggered flywheels. However, I might be

persuaded to sell to people using bona fide fitters to install one.

Toyota use a dual mass flywheel (the flywheel is in 2 parts, an inner and

outer assembly, damped in the middle) which is now showing signs

of wear causing a lot of rattle when idling or on very light

throttle openings. For God knows what reason they are charging

about 270 quid for a new one, they look more like they should be

over 500 to me, but don't say anything :-) So if the flywheels

old enough or abused enough to be scored it's best replaced.

If pressed I will sell the clutch kit, which includes a new release

bearing for a 3rd party to fit.

 

Fitting by myself will cost 175. Both prices do not incur any VAT,

I have a separate company for road car stuff, and it's not VAT registered.
