yes sir. its very important too. so after you re-build it a few times, you may notice that it has disappeared. when that happens, its usually due to lock tight buildup on the M3 washer that the bolt goes though to hold the grip onto the hub. if that happens, remove the bolt and washer, and clean it up to look brand new, or simply replace it with a new bolt and washer, and the it will likely come back just fine. took me a few times of looking into it to figure that out.
