Thrust Bearing Cooling Fan (Optional) - ITT 3610 i-FRAME Manual

• 1/2 in. NPT connection on the outboard side (551E)
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.
Pure-oil mist lubrication provides constant oil mist in the bearing housing. This system does not use the
oil sump, oil ring, or constant-level oiler. The drain connections in the bearing housing are used as part of
the oil recirculation system.
1. On each the radial housing, replace the 1/4 in. NPT plug (133H) with an oil-mist fitting provided by
the oil-mist system manufacturer.
The 1/2 in. NPT connection (551E) remains plugged because it is not required in the oil-mist sys-
tem.
2. On the thrust housing, replace the 1/4 in. NPT plug (133H) with an oil-mist fitting. Replace the 1/2
in. NPT plug (551E) with a 1/2 in. to 1/4 in. bushing and insert an oil-mist fitting provided by the oil-
mist system manufacturer.
3. For pure-oil mist, connect the drain lines (408A) to the outlet connections. This is not required for
purge-oil mist.
