 New guy here. I am doing the shake down inspection on
 my new 360 and can not get the main gear to lock when
 I open the dump valve. The nose works fine and the
 left worked OK until I put new seals in the cylinder.
 Everything swings very smoothly if I disconnect the
 hyd lines. It seems to me that the overcenter springs
 have no strength. I can easily move them and they seem
 shorter than the ones that I see in some of your
 pics.The hydraulic system works fine under power.
 Everything comes and goes as it should in the
 barn.Thanks. Jim@pt22_02557@yahoo.com
