I have a 450b crawler and it needs a steering clutch. Tried to remove track tension by removing the square head bolt with jam nut and nothing happened. So I cut the track pin and removed the track. Track frame had a broken bolt where the front cross member attaches and I wanted to fix that. Well in order to get frame off I need to remove the tensioner piston... how can I do this? Tried wrapping a chain and pulling it with a ratchet binder to blade, and tried turning with 4 foot pipe wrench. Any tips/tricks to getting it away from spring holder? Posted on crawler board but lots of knowledge here also. Thanks Matt
