        Welcome to CTOA Post,

        I used to own a LW-6.

        The swing cylinders are single acting. The brass fitting in the end is an air filter to keep dirt and debris out of that end of the cylinder.

        What has happened in your case is the cup seals on the piston have blown, letting oil by, and collecting in the unused portion of the cylinder.

        Time to repair or replace that cylinder. My guess is that you were using boom swing to move dirt with the side of the bucket – that's a no-no with these particular hoes. Kits are available through Circle-G and various other dealers that support this site

          Thanks Bob,  that sounds totally logical.  And I never intentionally move dirt sideways but I am not very coordinated with the bucket it does take alot of sideways force.   I have a heck of a time getting the cylinder off but I have just dismantled it in place.  I see a disintegrated seal.  I ordered several seals (cirgle g, sorry keno)  that I think are right and a few slightly larger and smaller just so I have it right.    we can close this ticket. problem solved.  thanks again!

            I know how violent those controls can be. Try slowing your engine down some. Another trick you can do is put restrictors in the hydraulic hose couplings, you don't lose any power, just the erratic movements. Many have done this and enjoyed the success.
