(immediately above the single row radial bearing). You must connect to both connections
on the thrust bearing housing, because there are two rows of bearings.

NOTICE:
Make sure that pipe threads are clean and apply thread sealant to plugs and fittings.
You can convert from ring-oil lubrication to oil-mist lubrication in pumps with ball bearing
construction. The radial and thrust end bearing housings (134) have pre-drilled connections for
oil misting:
• 1/4 in. NPT connection on the inboard side of the housing
• 1/2 in. NPT connection on the outboard side
Purge-oil mist lubrication provides intermittent oil mist in the bearing housing. This system uses
the oil sump in the housing, and requires the oil ring and the constant-level oiler.
