Rebuild kits are available from the usual vendors. To remove glass bowl loosen the retaining wheel and slip the retainer sideways. Sometimes the bowl will stick to the gasket but a couple taps with a plastic/rubber hammer will get it loose, just be patient. New pumps are also available, with or without glass bowl.
