d. “Provisions for oil mist lubrication” – These motors are packed
with grease. Storage procedures are the same as paragraph 5b.
e. “Oil Mist Lubricated” – These bearings are protected for
temporary storage by a corrosion inhibitor. If stored for greater
than 3 months or outdoor storage is anticipated, connected to
the oil mist system while in storage. If this is not possible, add
the amount of grease indicated under “Standard Condition” in
Section 3, then rotate the shaft 15 times by hand.
6. All breather drains are to be fully operable while in storage (drain plugs
removed). The motors must be stored so that the drain is at the lowest
point. All breathers and automatic “T” drains must be operable to allow
breathing and draining at points other than through the bearings around
the shaft. Vertical motors should be stored in a safe stable vertical
position.
7. Coat all external machined surfaces with a rust preventing material.
An acceptable product for this purpose is Exxon Rust Ban # 392.

Regreaseable Motors:
Non
−
regreasable motors with “Do Not Lubricate” on the
nameplate should have the motor shaft rotated 15 times to
redistribute the grease within the bearing every 3 months or
more often.
b. All Other Motor Types
Before storage, the following procedure must be performed.
1. Remove the grease drain plug, if supplied, (opposite the
grease fitting) on the bottom of each bracket prior to
lubricating the motor.
2. The motor with regreasable bearing must be greased as
instructed in this manual.
3. Replace the grease drain plug after greasing.
4. The motor shaft must be rotated a minimum of 15 times
after greasing.
5. Motor Shafts are to be rotated at least 15 revolutions
manually every 3 months and additional grease
added every nine months (see Section 3) to each
bearing.
6. Bearings are to be greased at the time of removal
from storage.
B1. Removal From Storage
1. Remove all packing material.
2. Measure and record the electrical resistance of the
winding insulation resistance meter at the time of
removal from storage. The insulation resistance must not
be less than 50% from the initial reading recorded when
the motor was placed into storage. A decrease in
