I've been pretty lucky that my bimmer hasn't had a lot of issues, but most of them I've been able to handle with the insight of the members of this forum. I think I have checked all the posts regarding cruise control actuators, even downloaded the cruise control actuator technical spec pdf from another website, and checked out pingu's post on actuator repair. The issue is: I took my actuator off to clean the contacts and lube the gears, when I put it back together, it doesn't work. I am under the impression that the strap should pull out at far as possible (based on how far I was able to pull the strap to disengage the throttle cable from the clevis). But the control belt drum gear has a "lip" that acts as a stop when the retraction spring holder is in place. So when it's re-assembled, the strap can only be pulled out about 2 inches prior to retracting. How much tension is the right amount of tension for the spring? And how much slack should the strap have under no load? I have the clevis right up against the edge of the actuator, yet the pdf shows it with a little more slack.
I'm pretty sure I re-assembled it wrong, but I'm at a loss to figure out how. I'm enclosing a picture, and thanks in advance for your help.
