Servicing the actuator did work. You are on the right track by running the engine and putting the gear handle down and time the gear handle return to the normal position. Use the service manual for that procedure. If something is about to fail it will fail big time after 4-5 cycles. Getting that actuator in and out will be a lot of labor and getting the system primed will take way longer than it should. Also all the other seals in other actuators in the system that has not been touched will now start to seep because of the added pressure. Order some extra seals and be ready to chase door actuators and things like that. Word of caution. Jack the aircraft to remove the actuator. It must be off the gear or the gear will fold. My project took ten weeks from start to finish. But the gear works great now.
