REFLECTOR: rebuild kit

[Reiff Lorenz via Reflector]

Larry,
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 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
I've attached his diagrams, explanations, and instructions for rebuilding the pump.
Hope this helps!

I need a rebuild kit 634 412 for the Parker 108 hydraulic power unit.  I talked to Velocity and they do not carry them anymore.  Any ideas.
