Boasun- Since the OP and I have a similar "whine", can you give a bit more detail about Greasing the packing gland/ stuffing box. I have fairly new traditional flax, that comes pre-greased. I wasn't aware that you could / should add anymore grease.
If there is no grease fitting, what do you do, Take the nut off and quickly swab some grease in there? What type of grease?
At least in my case, I loosened the nut off until lots of water was flowing out, and the nwent for a motor. It still whined, so I thought that woudl have ruled out the packing gland.
