Ie the way the system is setup currently, the clutch-pedal-pushed; clutch-disengaged is still out at the right distance and at the nut stop. And the clutch-pedal-at-rest; clutch-clamped is still showing what looks like the right gap. Sent from my Pixel 2 XL using Tapatalk |

And doc I'm running one of your spreaders. No circlip from memory. I think issue is a thrust bearing or something. Will look further. And Simon, no fluid in the rubber boot. Sent from my Pixel 2 XL using Tapatalk |

It is meant to be measured without the return spring and with the arm being moved away from the clutch cover to take out any free movement. The gap is quoted at 20 thou of inch, which is much less that shown. Too large a gap means the slave cylinder has to a long way just to take up free movement before actually operating clutch disengagement. |

Whilst you are at it check all clutch clevis pins for wear. JS |

New lever arm, about 50 bucks, new bearing carrier, about 25 bucks, DIY job, labour = zero $'s. (I am assuming you work on your mini like the rest of us, & your time is worth nothing!) ![]() Much cheaper than taking your daily driver in for a dealer service (EG Mercedes Benz oil change, About $350-$500) |

We are offering thoughts/ideas that might be helpful to sort out the problem and find an answer. |

That's fair enough, but from my experience those particular parts are well worn at this stage of any mini's life if they have not been replaced. Also remember the ball end of the arm that slots into the carrier hardly ever get lubricated, and has a dog of a life. Having just replaced a water pump with a new item (a lousy $48.50) because I thought I'd get away with recycling an old one from the back of the shed, I am quickly learning that using new parts will avoid disappointment and wasted time! |

Except those clutch parts, old good condition ones are better than new junk! |

Cheers guys, had an unexpected interstate trip. Home now, so I'll get to problem solving through the week. I checked the arm earlier and the ball was intact, but didint inspect wear closely. I'll check the other things listed too. In hindsight I remember noticing a vibration feel through the clutch pedal under light push taking the slack out of the pedal travel. So my bet at the moment is the bearing is cactus. The mystery shall be solved soon Sent from my Pixel 2 XL using Tapatalk |

It could also be the thrust plate on the diaphragm isn't hardened. There were soft AP ones sold here a few years ago. If buying a new release bearing plunger avoid the cheapo ones they are not hardened, and can't be because they are leadbrite steel or equivalent. But they can be drilled and a hardened bush pressed in. |

Here we go... ![]() I snuck a quick look before work. Once the clutch arm was out, this plunger was freed to pull out......only the inner gaurd was stopping it from pulling all the way out. I wonder what I'll find inside... |

![]() ![]() not a simple fix job like you would like thrust bearing floating around inside the clutch housing |

i would say that Either your throw-out-bearing has collapsed, or your "Thrust-plate" (attached to the diaphram by a spring-clip) has disintergrated |
