Case IH 685

[ONJ]

Need some help/advice on steering cylinder repair... We replace the ball joints and ran the tractor about 10 hours and then the O Ring blew on the clevis cylinder end.. well we put a new O ring in and then tried the steering and when it gets turned all the way to where the cylinder gets close to that clevis end it blows the O ring out again... just wondering if anyone had any ideas about that...
