Hi, as shown I have an adjustable cup with cage bearings. I haven't seen this arrangement before yet it's probably common; it appears there is a press fit retainer that seats into the cup and which prevents the bearing set from being removed. It's made of steel and states "pre-lubed" on it as well as "Hatta" (the brand I guess). This thing looks pryable. Anyone remove one of these retainers before? I want to clean things in there a little more thoroughly before repacking.
