I've got a new gimbal bearing that I'm getting ready to install (as soon as the tools arrive). Anyway, the manual says to line it up with the grease hole, if it has one... well, mine doesn't seem to have one (Pre-Alpha drive). There appears to be SOME grease in the bearing already, but I'm guessing I'm supposed to put more in before I install it. Anybody got any secret ways of greasing these things, without spending more money on tools? Or am I going to have to buy some special gimbal bearing greasing tool?
