Message: <blockquote data-quote="Tazza" data-source="post: 47391" data-attributes="member: 82">There is a tiny spool that slides back and forth inside that unit. It allows fluid through when the magnetic coil is activated.The hollow is nothing to worry about. They basically control fluid to a larger spool inside the control block that operates your aux hydraulics. Almost like power steering, little effort here produces more power in another point.If they are indeed stuck, the way i did mine was to use two pieces of alloy in a vice for soft jaws. Looking at the image you posted, holding the stem in the soft jaws by the end with the O rings, i held it with eht far right hand arrow part. Use a spanner and un-screw the stem that goes inside the coil. Note where everything goes, clean with air and solvent and re-assemble with oil. Remember, the stem part is very fragile, don't knock or bend it!. The plunger should move freely inside, if it doesn't, you need a new one.Hopefully that makes a little sense....</blockquote>
