To remove most gas cylinders you need a rubber mallet with a wood buffer to bang out the 5 star base from the bottom. To remove the shaft from the mechanism under the seat, use a pipe wrench with a "twist and pull" motion. For a stubborn cylinder shaft in the mechanism, you can try applying a little lubricant.
