Subject: Re:<E30> Stiff Clutch

If the clutch has changed to become stiff, the problem is, as Chris suggested in digest #604, related to the throwout bearing or pressure plate. However, if this probelem has always existed, another possibility is that the pedal spring needs to be ajusted. The clutch on my '88 iX is just great, but the clutch on the '89 had very little takeup range and was what I have described as "heavy."

There is a spring under the dash behind the clutch pedal which can be loosened or tightened to change the feel and the overcenter force of the clutch pedal which pushes back against one's foot as the clutch is depressed.

There are two nuts (one is a locking nut) on the shaft which runs through the center of the spring. These are very awkward to reach. On my '89iX, I backed the two nuts out all the way to reduce the spring tension using a 13mm open end wrench. If you want to try this, you'll find that this is a very tight fit. You'll need a wrench with a very narrow shank and you'll need an assistant to depress the clutch pedal while you turn the nuts 1/8 of a turn at a time!

By relieving the tension on this spring, I was able to significantly improve the feel of the clutch on the '89. The force trying to return the pedal to the at-rest position is reduced, but in addition, the over-center action is spread over a broader range of pedal movement. If you feel you have the same problem as I had, it is worth the effort to make this adjustment.
