Question about Skymaster landing gear system

[wslade2]

I have tried to upload some pictures. Hopefully it works.
you will see the hook mechanism engaged with the end of actuating cylinder. The bolt hole is for a bolt that goes through the mechanism into and attaching to the trunnion. The rod (with the lock nut) is what moves with the hydraulic pressure. You can see the plastic spring guide.
Even off the airplane with the bolt out it is still locked on. That's what I consider interesting geometry.
