Hi Bucky,
   
  Both of my mains would not free fall all the way.  They would come out about 5 inches and stop.  I had NO internal leaks anywhere in my system - after you helped me with that rebuild kit - THANKS!!  
   
  I replaced both over-center link springs and shortened the 2 long springs on both wheels - results? better, but still would not come down and lock.
   
  I checked my hydraulic fluid level.  It was almost to the top - about 3/4 inch HIGHER than MAX.  I suspected there was not enough room to push fluid back when free-falling.  Some people told me the fluid level didn't matter but it did - A LOT.
   
  I reduced the fluid to mid-point between MIN and MAX and tried again.
   
  Gear came down and locked without any hesitation or problem.
   
  I have heard of over-center link springs breaking but I CAN tell you that the new over-center springs are about 3/4 inch tighter (not installed) - (meaning the protuding part that enters the main gear leg is 3/4 inch closer in) so I conclude that after 6 years, the springs DO relax and could possibly even break.
   
  I'd suggest replacing over-center link springs every annual.  They are only $20 each and worth knowing the gear will free fall if needed.
   
   
  Matt

  I just installed my new nose gear drag link replacement from Randy Snarr.  It fit perfectly and appears to be built of top quality materials and workmanship.  I guess I couldn’t expect less from a champion builder. Thank you Randy for your time and for sharing the retrofit with other builders.
  When I did a gear retract my right main would not lock when I did the freefall.  I cycled the gear and tried another free fall with the same results.  I found the problem which was a broken over-center link spring (torsion type).  I have 430 hours on my plane and was wondering if any one else has had this problem.
