Hi bruceoz and other Twenty Two experts. Other than the graphite-impregnated gland packing, are there any other parts in the water pump that would be replaced during a rebuild? My cousin's unit leaks and while I have tweaked up the gland some, I'd prefer to pull it off and inspect it and replace parts that are in less than good condition, so recommendations for bushings, wear surfaces, etc. that would be best replaced while I have the "hood open" would be much appreciated. And is there a recommended lubricant other than generic grease?

If I had the option on packing, what would an alternative to graphite impregnated be? Just regular hemp soaked in plumber's green grease? That's what I used when plumbing although the components were all brass in that scenario
