ive got this neat bonnet for greasing bearings,(front too), a couple of pumps on the gun and you have grease thru the bearing,(and yes i like to put my own grease in such things as front bearings). other wise it can take a good 10mins of constant hand greasing to get grease in small outter bearing, the big inner can take 20min or more by hand, and tiresome at that point too. this way i can have rear drum off, grease, clean up, and reassemble, only takes a few mins.
