surface which contacts the pump casing. This ac-
tion will reduce rust and scale build-up.
Secure the back cover assembly by tightening the
cover clamp screw (58) against the clamp bar (59).
Do not over-tighten the clamp screw; it should be
just tight enough to ensure a good seal at the back
cover shoulder.
Final Pump Assembly
(Figure 1)
Install any leveling shims used under the pump
casing mounting feet and secure the casing to the
base (48) with the hardware (49, 50, 51 and 52). Be
sure the pump is secured to the base and engine.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.
Be sure the pump end and engine have been
properly lubricated, see LUBRICATION.
Remove the fill cover assembly (12). Fill the pump
casing with clean liquid. Reinstall the fill cover plate
and gasket (16), and tighten the cover.
Refer to OPERATION, Section C, and start the
pump.
LUBRICATION
Seal Assembly
(Figure 2)
Fill the grease cup (27) through the grease fitting
with No. 2 lithium base grease until grease es-
capes from the relief hole. Turn the grease cup arm
counterclockwise until it is at the top of the stem;
this will release the spring to apply grease to the
seal (see Figure 6).

The intermediate was fully lubricated when
shipped from the factory. Check the oil level regu-
larly through the sight gauge (41)
and maintain it at
the middle of the gauge. When lubrication is re-
quired, add SAE No. 30 non-detergent oil through
the hole for the oil hole cover (31). Do not over-lu-
bricate. Over-lubrication can cause the bearings to
over-heat, resulting in premature bearing failure.
