Cruise Control Actuator Rebuild Thread (pics soon)

[jkoebel]

I went to the Pull n Pay today and grabbed 3 VDO cruise control actuators from W123s and W126s and am planning to work on rebuilding. Plus my own. Total of 4

Three of them have motors that spin, one doesn't have any but I can probably use it for parts in some other fashion.

What I've discovered is that the three that do spin, the motor spins like its turning but the actuator arm that controls the throttle linkage does not move. This is because there's a spring tensioner inside of the motor which has worn out and is no longer keeping two of the gears together like it should. I'm going to try adding a shim or re-crimping the spring and seeing what comes out of it.

I'll post pictures of the whole process when I actually get into it soon, or at least a walkthrough of the inside of your VDO cruise unit, even if I can't fix it. I figure, the ones with good motors but no turning are good candidates for rebuilds.
