Clutch advice

Recommended Posts

I have one of my uprated, buy stcok based units built and ready to go. See below if interested:

 

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 475 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

plate. The gearboxes weight is allowed to swing on the plate centre,

bending the 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.
