Main Gear Actuator

[Burt]

Update: Discovered the part number of one of the parts in the actuator is the wrong part number in the IPC. Cessna tech support was able to find the engineering drawings and identify the correct part number. The part in question is index number 23 on drawing number 120 in the IPC for a 1966A model 337. The wrong part number in the IPC is MS28778-4. It is an O-Ring that the book calls "Packing". The correct part number is MS28778-015 and I was able to get it from Aircraft Spruce.
