well it's not loosing grain inside the access area, it's on the out side,dropping down in front of the axle, close to where the swing plate is that keeps the trash out of the fan area I think another poster is close, it's above the axle somewhere didn't get a good look at the area I was done and cleaning and noticed corn after I shut it down, will try to get a better look later,the machine only has 800 hrs on it so I don't think it's worn trough yet. Thanks Bob
