    Boom Cylinder Extends But Will Not Retract

    Cat 304CR (NAD00987) I've got a boom cylinder that will extend but will not retract. In other words, boom goes up but won't come down. When I try to boom down, I hear noise from the relief valve, but the cylinder only moves about 1/4". I don't have a way to test flow, but I have adequate...

Nothing on the head of the bolt suggests LH thread but I cannot break this loose using my...

    Grove RT865B tele. cylinder repair

    The bottom cylinder of this grove is leaking pretty bad so we pulled the boom (the three sections are still together on the ground) and put it on blocks. Looking at the cylinder the nut is recessed so slapping a big pipe wrench on it isn't an option yet. Any advice would be a big help.
