MAINTENANCE & REPAIR PAGE E - 14
Install the casing gasket (30) and secure the cas­
ing to the seal plate and intermediate with the nuts
(28). See Figure 1, reinstall any leveling shims un­
der the casing mounting feet, and secure the cas­
ing to the base (44) with the previously removed
hardware (45, 46 and 47).
Final Pump Assembly
Be sure the pump and engine are securely
mounted to the base.
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, intermediate and engine have
been properly lubricated, see LUBRICATION.
Fill the pump casing with clean liquid. Reinstall the
fill plug (47) and tighten it.
Refer to OPERATION, Section C, before putting
the pump back into service.
LUBRICATION
Seal Assembly
The seal assembly is lubricated by the medium be­
ing pumped and no additional lubrication is re­
quired.
Bearing
(Figure 2)
The intermediate was fully lubricated when
shipped from the factory. Under normal conditions,
add three shots of No. 0 lithium based grease from
a grease gun through the grease fitting (12) after
each 250 hours of operation or once each month,
whichever comes first. Do not over‐lubricate. Over‐
lubrication can cause the bearing to over‐heat, re­
sulting in premature bearing failure.
If grease is forced out around the shaft as
new grease is added, the bearing cavity is
full and should be disassembled and
cleaned immediately.
There are no provisions in the bearing cavity to
drain or flush the lubricant. The pump and interme­
diate must be disassembled to completely clean
and maintain this cavity.
Under normal conditions, change the grease after
each 5000 hours of operation, or at 12 month inter­
vals, whichever comes first. Change the grease
more frequently if the pump is operated continu­
ously or installed in an environment where variable
hot and cold temperatures are common.
When lubricating a dry (overhauled) intermediate,
fill the cavity through the lubrication fitting with ap­
proximately 2/3 lb. (0.3 kg.) of grease (approxi­
mately 1/3 full).
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
lubricant.
Engine
Consult the literature supplied with the engine, or
contact your local Deutz engine representative.
