REFLECTOR: Nose gear gas strut

[Alex Balic]

It is due to geometry- the 5 pounds or so applied normal to the pivot point
is probably about the same as 50# inches of torque applied at the gas strut
attach point.

I guess I don't understand what is going on?

Your saying just a finger push will overcenter it, but 50lbs from the gas
strut won't?  Does that make sense?

Dump valve works perfectly.

Once the nose gear is down, one finger is all it takes to get it over
center. 

So the extra 10lbs would be enough. I may go with 65-70lbs depending on
what's available.

Actually it sounds like the strut is fine.

gas strut pushes 50 lbs? thats pretty close to spec on those things.  10 lbs
would push it over center if the pressure was released. 

I think something is binding or possibly a hydraulic issue.  Maybe your
release valve is plumbed incorrectly?

Okay. Now I'm getting somewhere. :-)

With the nose gear hydraulic cylinder disconnected, the nose gear goes
overcenter every time. So I don't think it's a binding issue.

I pulled the gas strut and checked it on the bathroom scale and it's only
showing 50lbs during the compression stroke. 

So I guess it's off to NAPA. :-)

Thanks everyone!
