swb, no I dont change the bearings, tho I usually know by the logs when they were done. And am usually the one letting maintanance know when they start going bad. I know the overgreasing causes problems, that was why I posted. And after telling the guys in the shop of your post, they gave me their standard answer; if sanitationn has already taken out the seal with the high pressure hose, all you can do is pump grease in til all the water's out. And I thought the shields were a good idea, but I guess that leaves plces for bacterial growth according to Q.A.. Thank you, and sorry it took so long to get back to you.
