Post Subject: Stern gland greasing

Hi, I have just purchased a second hand boat and so I am new to boat maintenance. I need to fill my stern gland lubricator with grease. It is the screw type with the T bar which needs to be screwed down after each cruise. My question is, should the grease be re filled from the top of the round cylinder? if so is there any danger of air getting into the system and could it cause any damage? I have tried to unscrew the cylinder from the bottom and it doesnt seem to want to move and I am worried that I may damage it if I force it. Best Regards Barrie.

Dear Barrie, do not worry about air - thousands of boaters get air in there every year, all it will do is to pass into the stern-gear and straight out of the back of the boat. Whilst passing it will be easy to turn the greaser down so you would not normally stop turning until it got a bit stiffer. The easiest way to fill the greaser is to unscrew the whole tube assembly FROM THE BASE. Then using one hand to hold the open end over the hole in the baffle that should in the can of grease apply a degree of downward pressure while the other hand unscrews the T bar. You will feel the greaser move down as it draws grease from the can. Tony Brooks
