Note that on ANSI 3A™ power ends there is no
constant level oiler. As stated above, proper oil level
is the center of the “bull’s eye” sight glass [3856].
(See figure 5-1.)
Figure 5-1
In many pumping applications lubricating oil becomes
contaminated before it loses its lubricating qualities or
breaks down. For this reason it is recommended that
the first oil change take place after approximately 160
hours of operation, at which time, the used oil should be
examined carefully for contaminants. During the initial
operating period monitor the bearing housing operating
temperature. Record the external bearing housing
temperature. See figure 5-5 for maximum acceptable
temperatures. The normal oil change interval is based
on temperature and is shown in figure 5-6.
