Where should clutch release?
Just wondering folks, where is 'normal' for the clutch pedal to be when the clutch releases? Mine seem to be more to the top. Is that normal?
Thanks! |

Typically that is a good sign. When it grabs low, that's more indicative of a problem.

Yes, high is better than low, as long as the clutch does not slip. I have been struggling getting all the air out of my hydraulics for months. Just last weekend I got it feeling right. It had been releasing about 2 inches from the floor with what seemed like a lot of dead pedal to get there- now it is much closer to the top and firm all the way down.
There is a cam adjustment on top of the M/C, but that shouldn't be used until you are sure you have all the air displaced.

Have you used the 'go no go' gauge to see if the actual clutch is worn ?... which would produce this same position indicator in some instances...

as a general rule with hydraulic operated clutches it should grab fairly quickly but not too quickly. Some manufacturers have a spec for how far it should it travel.

There is an adjustment procedure and spec in the FSM, but it seems like way more trouble than it is worth. One of the factory methods is to induce water into the system and perform some sort of measurement- were they nuts?

Agreed - the higher the better. Just make sure you are able to push the pedal about 1 1/2" down before disengagement. This way you are assured the clutch disk is making 100% contact with the pressure plate.
