864T Stuck Track Adjuster! Help!

[Kb1ltg]

Hi, I have a 864T whose right side track will not adjust, I have attempted to put grease in and let grease out, nothing. The zerk is clean, does anyone have any idea on how to get this thing to extend and tighten up? I haven't lifted it fully off the ground yet but plan on putting it on stands today, maybe try to compress the adjuster with a bottle jack and a board, perhaps moving it inward will allow it to break free and then be able to pump up? Ideas? Thanks in advance! Jerry

I use a high lift jack in the track to jack the track up to compress the tensioner
