If you mean on the splines that the lever clamps onto, no there should be no play. The lever should clamp tight on the shaft splines but often they don't. If you let it go, it will get looser and looser, and can eventually strip the splines. What you can do to make the lever clamp down more is file out the gap that the bolt squeezes shut on the lever. Often the gap closes right up but the lever isn't tight yet.
