Hi, you`re better off replacing those toothed washers with normal ones and using Loctite instead.
Those things are ok for electrical connections but not for much else. Most of the toothed or spring washers will already be squashed at only 5% of the bolt`s preload force so they become ineffective long before the proper torque is reached.
Also it makes no sense putting them between a bolt and a washer.
Never mind, just want everyone to be and stay safe.

PS: does the front sprocket still have play ? There should be about 0,3mm if my memory serves me well.
