Self-adjusting Clutch Mechanism
The self adjusting feature of the hydraulic clutch operation has been around for quite some time now. For this reason, and because
the service intervals are
becoming longer and longer, it was only a matter of time, until it was introduced for the cable operated clutch as well. Particularly because this is cheaper, and it's not certain just how long the brake hydraulics are still
going to be around. The one without the other, is indeed possible, although it doesn't make much sense. Just imagine if there were service intervals for the hydraulic clutch operation. Especially, in the case of smaller
vehicles, the manual gearbox would still be around for some time.
First of all, in the above figure, a cable operated clutch can be seen. Should the pedal be pressed, the spheres are tightly clamped in the outside casing by a cone on the cable-casing. The remaining amount of cable
pulls on the clutch-release lever below. If in the disengaged position, this lever is moved further downwards, because of wear and tear of the clutch-plate, the red clamping piece pulls the casing downwards. Thus the
cable, from the pedal to the self-adjustment mechanism, also becomes shorter. If the clutch pedal travel is longer when disengaging, the spheres clamp the cable-casing further down. For the clutch release lever
there is now more cable available.
The, probably easiest way, is simply to replace the clutch cable, even though only the tounge of the clutch lever is defective. Indeed, the replacement part isn't cheap. What we're talking about, is the hanging in of the
clutch cable again. When hanging the cable out, it has the habit of pulling the cable right into the casing. Should it, nonetheless still be hung in, the clutch will slip miserably. That it can only be done with special tools,
or with the help of a second person, is not quite true. However, one can never be sure, when the pulling on the cable and the never ending (and seemingly senseless) twisting and turning of the casing, will be
crowned with success and the cable will protrude far enough out of the casing. Now, whatever you do, don't let go of it. Either the plastic part, whose lower section has two buds which can be joined to the cable, is
dangling there, or you have prepared a wire construction which holds the adjustment position, until the cable is mounted on the clutch side. 01/10
