Babolat Sensor Base Clamp

Hello Everyone,
New to the page here and looking for some wisdom! Just got a used Babolat Sensor stringing machine. It’s in great shape, but I have discovered that one of the base clamps “auto release functions” was not working. Upon investigation I discover the small silver arm that holds the rod in place was moving freely when the base clamp wasnt depressed (not locked)..the rod falls right out of the bottom of the base clamp..but it works perfectly fine when the clamp is locked. I have no clue how to fix it.

@DylanNelson219 - I did contact Babolat to get a couple of new bases. I had one which would not stay in the down position (Locked). They had about a dozen left at that time. You can call Babolat @877.316.9435 extension 293. IIRC the bases were $300/each. I went ahead and bought two since once they're gone, they're gone.

As to how to fix, I have no idea; but @abllee2198 might.

About how long ago was that?

Sorry i cannot help you as i dont have this machine.
Anyway seems to be something simple. Compare it with the other one that works to see differences

I have removed that little screw on the right but that pin that goes across wouldn’t budge.
You probably want a "roll pin punch" set. I just looked at my sensor (it's a bit dusty...) and it looks like one side of the pin is mushroomed. You'd want to tap it out from the non-mushroomed side, obviously. I would probably wait 'til Babolat got back to you first, though, it looks like it's the main pivot point for the entire lever assembly... If there are other moving parts in there, it may be non-obvious how to get it all back together if that pin is holding it all in one piece.

I speculate that there was (is?) a spring underneath the set screw in the right red-circled area that spring loads the lever arm to keep the clamp head up. You could confirm this by disassembling the other base, but then you might end up with two dead clamp bases instead of one ;) If I had more time, I'd take apart my clamp base assembly to confirm.

If you look inside, does it have 1 spring or 3? If it's the one with 3 springs way in the back, they will, or at least used to just replace them for free as they are defective. In any case, you can take a look inside while the tightening clamp is open and look at the springs.. springs should be up right, if there's an issue, like I had with mine, at least one will be missing or look a little off.
