Yep! As these guys said, a little drip is ALWAYS good........

As stated, that is packing, and unlike hydraulic packing, it is water lubed. watch a backhoe, trackhoe, bulldozer, skid-steer or bobcat work and wou can wipe a film of hydraulic fluid from the hard chrome hydraulic pistons. Kinda the same thing, but you need a little more "leakage" in this case to keep them cool.
