good Lord have mercy,
do any of you people actually believe the grease your slinging in here..
word.
grease is a hydrocarbon thats solid at room temprature, but does liquify when heated, so thats what keeps the bearing lubed..not the giant blobs of grease.
saying that, as the grease used up by the bearing, new grease has to be there to replace it, so that where the big globs come in, thats also why pumping grease into the zert fitting on a regular basis pays off saving your bearings.
and it's almost impossible to over grease a axle, because the outer bearing doesn't have a seal, so pump grease in till it oozes out the edge of the outer bearing and put the dust cap back on, you'll be set for life.
how do I know this.?
I used to be a flight engineer on a CH-54A skycrane..it has 6 rotor blades hung from a articulated hub..the hub is full of bearings..I had to pump a 5 gallion bucket of Grease, osolating bearing, into the rotor head, and also the tail rotor head, and the servo's and just about every zert fitting it had..
after a good long flight, liquid grease just dripped out of the thing..it was ugly.
