Help with FX3 actuators/faults

[Thomas ZR-1]

Hi Charlie, the rear actuator you purchased from me some days ago works fine...I checked this before selling to you. And as I explained to you: the plastic gears in the head of the actuator may crack after 30 years...and that`s the reason why they don`t do the reversing. They run in one direction without stopping...until time out. As I told you send me the faulty actuator and I replace the cracked pastic gears into HD aluminuim gears and they will work fine again.
