Refurbing fixed clamps on Gamma 8500 ELS?

#1
The fixed clamps on my club's Gamma 8500 are pretty shot. It's very difficult to turn the adjustment dial on the back of the clamp, and the clamping levers are very stiff and don't operate smoothly at all. One clamp's lever doesn't even move into that locked position once it gets over center, although it holds the string in place just fine (with much required effort to close the lever). So what can I do here? Can I disassemble the clamps and apply sewing machine oil to those moving parts? Also, is there any way to make the base levers operate more smoothly, although they are less of an issue.

Well, it's a really uncomplicated clamp. If you unscrew the adjustment knob all the way there's basically only 3 points that you can lubricate. You can lube the threads where the adjustment knob screws in . You can lubricate the single ball bearing embedded in the underside of the adjustment knob. And you can grease the track it rides on.

Great, thanks. I quickly strung a racquet on it for the first time the other night, but then I was out of there. I'll take a closer look at things tonight.

Actually, you might want to put a dab of grease in the area where the roller contacts the clamp and if you can it wouldn't hurt to get a drop of oil into the roller but that's more easily said than done.
