Clutch slip?

[OctaneBooster]

I have occasionally experienced what feels like clutch slip at high speed in top gear when accelerating. Is this a sign of clutch wear or the clutch not being up to the job, or both? Any worthwhile upgrades or recommendations for replacement? Car is a Griffith 430bv with 40k from new, very probably on its original clutch.

Thanks in advance

Mine has the same symptons. Perhaps it is a common problem - or is my clutch knackered!! Whichever, there seems to be no detrimental effect to the driving experience.

No detriment to driving 99% of the time here too, just an uneasy feeling of impending failure.

You will both be buying new clutches in the future. Mine slipped for a couple of months before I replaced it, you will find a gradual deterioration until one day it doesnt work anymore.

Ditto, one day occasional slipping at full welly, the next, max 50 mph at low, low throttle and a slow drive to Neil Garner.

Mine turned out to be wrong clutch fitted, , by previous owner.

My brothers Chim is currently doing the same thing think you will find its the pressure plates inability to keep the driven plate clamped tight enough under power/load subject to the driven plate not being knackered or contaminated the final outcome will be a new 3 part kit anyways.

I had this a while ago. Changed the clutch and no probs since.

IIRC you can tell if your clutch is on the limit by the position of the bearing (release bearing?) that is visible..somewhere... I'm not mechanical.... but Topcats showed me up on the ramps this silver bearing that gradully moves along its shaft as the clutch wears until it hits the end, IIRC it takes up the slack as the friction plates wear. When it hits the stop there is no more adjustment and the clutch will wear a bit more then slip as the plates arent push together properly. I suspect i havent described this properly at all , someome will hopefully know what I am talkign abotu and explain it better,

I had mine changed about 4k miles after this bearing reached the limit of its travel, the plates that came out were almost bare of material ! Clutch never actually slipped.

That sounds like a good desciption as the driven plate wears the fingers move out towards the relaese bearing pushing it further back on its support sleeve mine is right back and heavier than it should be but no slip.......yet
