Thanks for the input guys.

If I was to use #140 GL-5 how is this introduced into the joint reservoir?

I'm thinking of a process of cleaning the area around the 'zerk' . . . real well, remove the 'zerk' and install a pipe nipple, rotate the shaft until the nipple is pointing upward, and then fill the nipple with oil using a squeeze bottle. As long as the nipple extends above the highest bearing cup oil might be feed into all four cups and the central reservoir. Perhaps the trapped air will leak past the cup seals slowly, so maybe 'soak' time will be important. Moreover if the oil just pours out of the lower cups due to seal failure then I'll go back to thinking about grease.

Is there a 'grease gun' out there designed to pump heavy oil?
