I've had a 7435 spinning reel for 6 yrs. Was still working good until recently when it suddenly locked-up while retrieving. One of the 3 screws (the front one) that attach the arm (or foot) to the housing fell out and wedged between the housing and the rotor. It would have been real easy for me to check the tightness of that screw when having the rotor off for routine cleanings, but i don't think i ever did. Unfortunately that screw also got caught up in the anti-reverse mechanism spring and dislodged it. I tried to reinstall that small spring but couldn't get it back on..... my hands aren't real steady anymore, and maybe a special tool/pliers is needed. Bottom line: check tightness of that arm screw whenever you have the rotor off.
