Sealing

The sealing consists of a rotary shaft seal running on
the bushing which is glued on the auger hub. In addi-
tion  a  slide  ring  pretensioned  by  O-rings  is  mounted
on the auger hub. This slide ring serves as additional
protection  for  the  rotary  shaft  seal.  It  is  turning  with
the  auger  and  is  sliding  on  the  wear  plate  which  is
bolted to the housing.

When dismounting the auger, the O-rings and the
slide ring remain on the auger hub and can be pulled
out of the machine together with the auger.

When  reinstalling  the  auger,  make  sure  that  the
complete  auger  hub  (especially  the  glued  bushing)
and the slide ring are free of dirt in order not to dam-
age the rotary shaft seal.

The surface of the slide ring which is in contact with
the wear plate during operation and also the bushing
must be greased before installation, the other surfac-
es of the sealing must be free of grease
