Canned pump carbon bearing setting

In replacing carbon bearing(B012),fix the  carbon bearing into bearing housing after putting the sheet(S26) into a cutout on the outer side of the carbon bearing.

 Tighten the setscrew(231) until it contacts the sheet. At this time, it is recommended that carbon bearings rotate to the right-hand and left-hand slightly.

 If the setscrew tightening too much that may cause carbon bearing crack & tightening too loose that may cause carbon bearing turning when star up.
