PAGE C − 5 OPERATION
It is not necessary to drain the oil from the seal cav-
ity unless the pump casing will be separated from
the motor housing.
Lay the pump horizontal on a flat work surface with
the seal cavity drain plug facing up. Remove the
drain plug slowly to release any pressure. Install a
short pipe nipple in the hole. Place a clean contain-
er under the plug and roll the pump on its side to
drain the seal housing.
Condition Of Oil
Check the condition of the oil drained from the
pump. Clear oil indicates that the pump seal is
functioning properly. If the oil is milky or contains
a small amount of water, it must be changed.
If the oil contains a large amount of water, it must
be changed, and the seal must be checked before
the pump is put back in operation (refer to the
Maintenance and Repair Manual).
Adding Oil
Refer to Table B−2 in INSTALLATION for pump oil
capacities.
The grade of lubricant used is critical to the opera-
tion of this pump. Use SAE No. 10 non-detergent
oil. Oil must be stored in a clean, tightly closed con-
tainer in a reasonably dry environment.
When lubricating the seal cavity, remove the lu-
brication plug as indicated in Draining Oil. Add the
non-detergent oil through this plug hole. With the
pump positioned horizontally, sight down the plug
hole and check that the oil level is high enough to
cover the seal spring.
Install and tighten the lubrication plug.
