The one that comes down out of the control panel it has a new cork seal in it and I tighten the 1wo screws and it just pulls right out there is no way I can see to get it to seal. 1958 420 W Help Thanks [Reply]   [No Email]

You gotta use the steel ring to help compress the cork. Also try to get the tubes lined up as good as possible. The rubber ring is a good idea tho....... Adrian   [Reply]  [No Email]

I got a 58W and a coincidence just ordered two of those seals thru the local JD dealer. They cam in made of a rubber/neoprene material just like ten years ago. Maybe different parts of the country get the seals make by a different manufacturer? i donno, but have never seen a cork one.   [Reply]  [No Email]

I don't have a schmatic of your system, but I'm thinking the line you're talking about must be a return line and not a pressure line. I have a JD 40 and there are no cork seals in it's fittings. I think I'd try an O ring or a square cut rubber seal.   [Reply]  [No Email]

Ohio tractor guy says I need a steel ring I must have lost or miss placed it that will squeeze the cork ring and make it seal. thanks for the reply   [Reply]  [No Email]

This practice has eliminated my leaks.....   [Reply]  [No Email]
