Maintenance
Interval Task Procedure Notes
Weekly or
Bi-Weekly Grease lubricated bearings
(moderate to dirt, dry conditions*)
Apply grease to the inlet and
outlet bearing grease zerks while
the fan is operating. Stop
application when grease is seen
being purged through the bearing
seals. Once the purge level is
determined, use the minimum
amount of grease that is possible
to reach purge (purge = point at
which grease is visually seen
escaping from the bearing seals).
For most ambient temperatures
(0 to 150° F), use a high quality,
all-purpose, Lithium/Lithium
complex based, #2 EP grease
(Mobilith AW-2, Texaco Starplex
2, Shell Alvania #2, or
equivalent). For “extreme”
ambient conditions (less than 0° F
and more than 150° F), a
synthetic or specialty purpose
grease may be considered. For
specific recommendations,
contact your closest Trane
Sales/Service office.
