Having trouble with your nose gear door hydraulic cylinder? So is everyone else. Consider:
Mishler Mechanical Replacement
or
Landing Gear Actuator's Rebuild Kit Packing's
Packing's can be ordered from HD distributing over the Phone (877) 838-7325 , Online www.hddistributors.com , or located at (if you would prefer will call):

Cylinder Rebuild
I don't know where you can find a rebuild kit. They seem strangely difficult to locate. I did find some good info in the Lancair community. They use the same pump/cylinder system that Velocities do. According to their experts, the only non-standard part in the pump rebuild kit is the poppet valve, so you only need a rebuild kit if the poppet valve is leaking. Usually, you just need these standard O-rings from McMaster:
013-90, Spool Seal (013N90)
014-90, Check Valve Body seal (014N90)
908-70, Hex Plug Seal
908 Durometer 90
For more info, see Lancair builder Chris Zavatson's site: http://www.N91CZ.net
Linked below are his diagrams, explanations, and instructions for rebuilding the hydraulic pump and cylinders.

notes
MIL 5606 uses Nitrile packing's
Pay particular attention to the orientation of the Poly Pak's the open portion faces towards pressure. Looks a little odd buts makes sense if you think about it. The more pressure you put on it causes it to flare out and increase sealing pressure.
