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.
