Title: Clutch pressure plate Post by: jreacock on January 11, 2017, 11:00:12 PM Hi. Just wondering whether anyone has an opinion on the groove that has been worn into the pressure plate on my Spyder.
The clutch disc seems to be almost as new, and the bearing rotates freely (maybe a little too freely) - so I'm wondering why this scoring has happened. Is it normal - or is it knackered? Thanks.

Either way that needs replacing - the wear is too much. Title: Re: Clutch pressure plate Post by: rossocorsa on January 12, 2017, 12:07:48 AM Looking at that I'd suspect that the driven plate is more worn than you think, it is difficult to tell by eye how worn it is you'd need to micrometer it. Not very expensive to change if it's already apart.
Title: Re: Clutch pressure plate Post by: jreacock on January 12, 2017, 01:06:18 AM Thanks guys. I thought that may be the case.
Does anyone have a source for a full kit - rather than just the 2 piece? Guy Croft seems to do the bearing, and BetaBoyz have the plate and disc - but you used to be able to get complete kits fairly easily. I've been looking for some time now, but can't really find anything. Thanks again. Justin.

Title: Re: Clutch pressure plate Post by: jreacock on February 19, 2017, 10:03:10 PM I don't think it had the return spring on it.
It's all apart now, (just about to go back together) but there's no spring visible in the pictures that I took before disassembly. Title: Re: Clutch pressure plate Post by: squiglyzigly on February 20, 2017, 08:47:32 AM I haven't got my car here to take a photo, but there is a small hole cast into the clutch arm. That's for the missing spring that keeps the bearing just floating above the pressure plate fingers rather than the stiction/friction of the cable not quite releasing after each pedal push and hence the bearing is always having a little pressure applied.
Title: Re: Clutch pressure plate Post by: WestonE on February 20, 2017, 01:11:53 PM You will probably have to buy the bearing and clutch plate & cover separately these days.
Eric Title: Re: Clutch pressure plate Post by: jreacock on February 20, 2017, 11:01:17 PM Hi Eric. Yes - I got the bearing from Guy Croft (£39), and the Valeo pressure plate from Mister Auto for £85, which now seems to have increased to more like £167 from a few weeks ago:
