I’m in the process of putting my BP series one step pulley back together and have a question about the zerks on the saddle. I’ve flushed the lines and cleaned the zerks but can’t get the way oil to transfer through. I’m using the the “push lube” system from H and W. Previous owner had of course used grease but I’ve managed to get that out. In fact if I take the zerk out and put way oil in the threaded hole it comes out all the distribution holes freely. The problem seems to be the push lube pump cannot generate enough force to depress the ball. I can do it manually with a small pick. So I don’t think the zerk is stuck or clogged (I’ve soaked and flushed them with compressed air). How do you guys oil the ways? Thanks
