the back cover gasket (55) and slide the back
cover assembly (50) into the pump casing. Be sure
the wear plate does not bind against the impeller.
NOTE
To ease future disassembly, apply a film of grease
or ‘Never-Seez’ on the back cover shoulder, or any
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 (47) against the clamp (46). 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 (1) to
the base (48) with the previously removed hard-
ware (48, 49, 50 and 51). Be sure the pump is se-
cured 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 and engine have been properly
lubricated, see LUBRICATION.
(Figure 2)
Remove the fill cover assembly (68). Fill the pump
casing with clean liquid. Reinstall the fill cover as-
sembly and gasket (72), and tighten the cover.
Refer to OPERATION, Section C, and start the
pump.
LUBRICATION
Seal Assembly
(Figure 2)
Fill the bottle oiler (13) with SAE No. 30 non-deterg-
ent motor oil. Check the oil level regularly and keep
the bottle oiler full.
Bearings
(Figure 2)
The intermediate was fully lubricated when
shipped from the factory. Check the oil level regu-
larly through the sight gauge (31)
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 air vent (17). Do not over-lubricate.
Over-lubrication can cause the bearings to over-
heat, resulting in premature bearing failure.
NOTE
The white reflector in the sight gauge must be posi-
tioned horizontally to provide proper drainage.
Under normal conditions, drain the intermediate
once each year and refill with approximately 18
ounces (0,5 L) of clean oil. Change the oil more fre-
quently if the pump is operated continuously or in-
stalled in an environment with rapid temperature
change.
Monitor the condition of the bearing lubri-
cant regularly for evidence of rust or mois-
ture condensation. This is especially im-
portant in areas where variable hot and
cold temperatures are common.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.
