Need some help. I am reassembling the 3 gears that need to come out during a clutch replacement. The top a bottom gears have the ring nuts that require a special tool. The bottom gear ring nut was torqued snugly but the top ring nut was totally slack. I could rock it back and foth with my fingers. The "locking tabs" were, however, engaged so the the nut could not have loosened by itself. It this correct? Should there be no torque on the top nut? If this is wrong, how much torque should I apply? Thanks.
