Maintenance
1. Remove the wear rings from the suction casing (100S) and the diffusers (100H). Use
suitable pry or puller tools to force the rings from the fits. You can also machine the rings for
removal.
CAUTION:
Make sure that the unit cannot roll or fall over and injure people or damage property.
2. Install the wear rings:
a. Thoroughly clean the wear ring seats and make sure they are smooth and free of scratches.
b. Chill the new wear rings (103) using dry ice or other suitable chilling substance and install
the rings into the fit of the suction casing (100S) and the diffusers (100H). Use Loctite 635
between the casing and casing wear ring. Be prepared to tap the ring in place with a hardwood
block or a soft-faced hammer.
