VKB T Rudder Mk. IV different tension between left and right sides

Postby Ranma13 » Fri May 12, 2017 15:10

Hello, I'm having an issue with my T Rudder Mk. IV's. The tension between the left and right sides is noticeably different, with the left side requiring more force to stomp down on vs. the right. I've tried the cam setting in both hard center and soft center positions and the problem occurs with both, though it's slightly less noticeable with the hard center. I've also tried adjusting the spring force between normal and high, and on normal the tension difference between the two sides is slightly noticeable, and on high, it's very noticeable. In all cases, I have the tension screw unscrewed all the way so that it doesn't apply any pressure to the cam arm.

Is this behavior normal, and if not, is there any way for me to fix it on my end?

I have Mk.II and is slight more heavy in left side, think that is inherent of one lever CAM.

Just to confirm - Sokol is right.
Also, the difference is rather slight, and since you're pushing these pedals with your legs, barely noticeable.

Changed to the heavy spring setting and I got really noticeable, to the point where I will probably go back to the lighter one.

Shouldnt this be fixable though? I mean, the springs should be linear, and even if they wouldnt, there would still be function that describes the relation between spring force and elongation of spring. This would make it possible to design cam that offsets this (with nonlinear spring only for one tension setting though). Or is my mind totally screwed right now :?: :?: :?:

Probable not related to spring - since is used only one, but in CAM profile.

Anyway their profile is already not symmetrical:

Left side angle is less pronounced than right side - in both profiles.
