1 take the FITTING out of the rotating rotary union. If it slows down it is hyd. If not it is mechanical. 2 If hyd it could be coupler not making good contact and pushing the tips of the couplers in or the soliniod not receiving fire -12v and magnetizing (put knife blade on sol. and see of mags) and releasing poppet or stuck poppet. 3 If mechanical it is probably stuck lower spring canister _ torque cams. Remove clean polish grease and reinstall.
