Need help figuring out what to MEASURE when adjusting a self-adjusting
clutch pedal bolt. http://www.bild.me/bild.php?file=3835507bolt.jpg I've adjusted the bolt all the way in, half way, and all the way out: http://www.bild.me/bild.php?file=8057083bolt2.jpg No matter whether I adjust the bolt all the way inside the clutch pedal (turning it CCW facing the pedal like a foot would). Or if I turn the adjusting bolt all the way out of the clutch pedal (turning it CW). Or halfway between... I don't feel any "slop" anywhere (e.g., between the rounded tip and the master cylinder piston cup). The *feel* of the clutch pedal engagement changes drastically between all the way in and all the way out though. But clutch pedal feel is not the question (mainly because I don't know how it "should" feel). So the question is only about what to measure, and how. The question is only about WHAT to measure with a ruler and how to measure it. |

The throw out bearing needs to release from the clutch plate in the bell housing. You can't adjust it by a ruler. You need a little slop in the pedal so the plate is not always engaged at the risk of burning the plate. ....at least back in the day. Two cents. |

![]() The rod (bolt) needs to be adjusted so that there is about 0.1" clearance between the end of the rod and the clutch master cylinder piston with the pedal 'up' (not pressing it). You can't see the piston or where the rod contacts it, so you have to do it by feel. Push the pedal gently by hand* until the space is taken up. If you can't feel any space, you might have it too tight. Back the rod out of the master cylinder until the clearance is obvious and then gradually extend it. When it's correct, tighten the jamb nut to keep it in place. The idea is that the clutch master cylinder has to be able to 'relax' all the way rearward when not pushing on the clutch. At the last point in it's travel, the piston opens up the port to the fluid reservoir and lets fluid in to make up for leakage. *Feeling the rod clearance is easier by hand. Your foot isn't sensitive enough to judge the small amount of play. -- Paul Hovnanian ------------------------------------------------------------------ Never put off till run-time what you can do at compile-time. -- D.

Thanks for the advice as, well, as I NEED advice. I can't disagree about the measurement, but I'm not sure how to measure that. The problem is that I don't *feel* any slop with my hand pushing along the axis of the bolt away and then toward the master cylinder. You can't see the piston or where the rod contacts it, so you have to do it by feel. I know what it looks like as I rebuilt the master cylinder, so I know what you're talking about. I just don't feel any slop at all no matter how I adjust the bolt. Push the pedal gently by hand* until the space is taken up. I'll have to try this again. Hopefully I can hear a click or feel the "space" being taken up. If you can't feel any space, you might have it too tight. I'll try again. Back the rod out of the master cylinder That means to turn the bolt INTO the pedal (and away from the master cylinder), which is, in effect, a shortening of the bolt. until the clearance is obvious and then gradually extend it. OK. That sounds like a plan. It's a normally threaded bolt which is threaded into the clutch pedal. Is this a good plan? 1. Shorten the bolt by screwing the bolt into the clutch pedal assembly. 2. Then feel for slop (there "should" be plenty of slop, I would think) between the end of the bolt and the master cylinder (this is on the other side of the firewall so it has to be done by feel) 3. Once I get a feel for the slop, then lengthen the bolt by twisting the bolt OUT of the clutch pedal, which "lengthens" it. When it's correct, tighten the jamb nut to keep it in place. That part I understand! ![]() The idea is that the clutch master cylinder has to be able to 'relax' all the way rearward when not pushing on the clutch. At the last point in it's travel, the piston opens up the port to the fluid reservoir and lets fluid in to make up for leakage. That makes sense. Thanks. *Feeling the rod clearance is easier by hand. Your foot isn't sensitive enough to judge the small amount of play. I'll try again now that I understand it a bit more. I agree that even my hand isn't sensitive enough, so a foot will never do it. |

If only I knew what to measure as I think it's for a millimeter or two of 'slop' between the rounded end of the bolt and the master cylinder piston cup. But I don't feel that slop in any case. And I don't know where to measure it either. Hence the question. |

Normally, there should be about 1/2 inch between the resting position of
the pedal annd its thrust position (completey up. This is for preventing continuous fricton inside the clutch.

Pedal freeplay B. Pushrod play The reason they seem to be the same thing is that, with one finger on the pedal, you can push the pedal down about 5mm until you hear and feel the pushrod hit the master cylinder piston cup. I can't yet distinguish between the two (freeplay & pushrod play) with my finger or measurement at the top of the rubber part of the pedal position. |

If you can't feel the play, it doesn't have any. If it is meant to have play, then fix it so it does. And I don't know where to measure it either. For master cylinder clearance - At the pedal pushrod in most cases. For slave cylinder clearance - at the slave cylinder in most cases. Hence the question. Better than 90% of vehicles with standard transmissions today have NO MANUAL ADJUSTMENT PROVISIONS. Mad MaX is an IDIOT. Yep, manufacturing tolerances have improved out of sight in recent years. It's got very little to do with "manufacturer's tollerances" - althought they ARE a lot better. The main thing is they are "self adjusting" |

He doesn't know the olde heat and bend the rod trick... maybe use some all thread and burn an adjustment hole in the floorboard. -- Tekkie |

The poor lad reminds me of the Irisnman I shared the house with in Zambia. Anything more complex than a retractable ball-point pen had him totally flummoxed. To keep his level of frustration below the point of "blowing smoke" he was restricted to using Bic stick pens (pencils were no good because a pencil sharpener was beyond his level of comprehension) Sharp as a marble aye? -- Tekkie |
