Help repairing nose gear actuator

[Ernie Martin]

My A&P is about to start repairing the nose gear actuator on my 337G to correct a small leak of hydraulic fluid. He's done it before on the main gear actuators but not on the nose gear, and the manual has little or no information on this. Anything he should know? Any special tricks? We already have all the parts (O-rings, etc.) he may need, but is there anything else he should be aware of?

Thanks,
Ernie
