tooquicktostop Posted January 25, 2012 Share Posted January 25, 2012 I just brought a clutch kit from Toyota, pressure plate, bearing etc, it was about £400 IIRC Quote Link to comment Share on other sites More sharing options...
Guest smithy Posted January 25, 2012 Share Posted January 25, 2012 was that a oem clutch kit? Quote Link to comment Share on other sites More sharing options...
CanisLupus Posted January 25, 2012 Share Posted January 25, 2012 OEM Clutch parts aren't that expensive(bar the flywheel which is ^^). You will definitely need the clutch plate itself, new bearings and i would recommend the 2 snap rings. Pressure Plate could be worn too. 350-400 sounds about right for all of the parts(including pressure plate) you need for that job. Quote Link to comment Share on other sites More sharing options...
Robzki Posted January 25, 2012 Share Posted January 25, 2012 Better to change it all while you are in there Quote Link to comment Share on other sites More sharing options...

Guest smithy Posted January 25, 2012 Share Posted January 25, 2012 is an oem clutch the best to put in or it would it be better to get a aftermarket clutch? Quote Link to comment Share on other sites More sharing options...
CanisLupus Posted January 25, 2012 Share Posted January 25, 2012 What kind of power are you running? Until BPU the stock one should be ok. As an alternative you could use Chris Wilson's clutch which is based on the stock parts or a single plate TRD one. Quote Link to comment Share on other sites More sharing options...
Nic Posted January 26, 2012 Share Posted January 26, 2012 is an oem clutch the best to put in or it would it be better to get a aftermarket clutch? A stock clutch will be the smoothest and quietest option, they are good for around 400hp. If the clutch is slipping as much as you say ie. revving in gear with no drive, you may well have also damaged the flywheel. Quote Link to comment Share on other sites More sharing options...
neo2810 Posted January 26, 2012 Share Posted January 26, 2012 What's a stock flywheel cost these days? Quote Link to comment Share on other sites More sharing options...
dude Posted January 26, 2012 Share Posted January 26, 2012 What's a stock flywheel cost these days? over £400 !!! If the clutch has been slipping that much the flywheel could well be junk I have seen them compltley blued with heat. Quote Link to comment Share on other sites More sharing options...
neo2810 Posted January 26, 2012 Share Posted January 26, 2012 I replaced the clutch plate recently but it's still chattering at low pressure after 1500 miles so I'm thinking the flywheel will need replacing at some point. Not sure if the chattering will damage the clutch plate over time so I may have to replace the whole lot at what appears to be about £800. Ouch!

dude Posted January 26, 2012 Share Posted January 26, 2012 There is a test you can do on the flywheel to see if its in tolerance, you mark it and see how much movement between outer and inner on the rubber damper there is. Quote Link to comment Share on other sites More sharing options...

Nic Posted January 27, 2012 Share Posted January 27, 2012 its only be doing it couple of days i stopped driving it! A slipping clutch generates a lot of heat which can quickly trash the flywheel. Hopefully it'll be okay but you won't really know until you drop the gearbox to inspect it. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 27, 2012 Share Posted January 27, 2012 Available now: Uprated MKIV TT clutches. 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 455 pounds plus VAT , 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 a lot of clutches damaged by people without the right gear (a ramp and transmission jack, plus correct circlip tools and fitment) or clutches fitted to patently *uggered flywheels. I will do a supply only if you feel competent to tackle the job or are using a bona fide garage to fit the clutch 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 £400 + VAT for a new one, they look more like they should be over 500 to me, but don't say anything :-) The very similar LUK dual mass flywheel on Maseratis is nearly £1000 + VAT.... So if the flywheels old enough or abused enough to be scored it should be replaced. Fitting by myself will cost £175 + VAT. Reply privately if interested please.
