Yanmar 32HP track hoe. need repair help

There should be a relief valve you can loosen to allow any excess psi(grease) out of it.
Rotate machine perpendicular to the track that has problem so you can use the dipper to prop/jack that track up off the ground. BE CAREFUL!
Not sure if track needs to be removed to remove cylinder? I bet the seal on the cylinder is shot.
Could be something as simple as lousy grease nipple but I figger you would have checked that?
