MAINTENANCE & REPAIR

PAGE E - 11

Be sure the pump and power source have been
properly lubricated, see LUBRICATION.

Remove the fill plug assembly (5) and fill the pump
casing with clean liquid. Reinstall the fill plug and
tighten it.

Refer to OPERATION, Section C, before putting
the pump back into service.

LUBRICATION

Bearings

The pedestal was fully lubricated when shipped
from the factory. Under normal conditions, add one
shot of No. 0 lithium base grease from a grease
gun through the grease fittings (15 and 22) after
each 250 hours of operation or once each month,
whichever comes first. Do not over lubricate. Over
lubrication can cause the bearings to over heat, re­
sulting in premature bearing failure.

If grease is forced out around the shaft as
new grease is added, the lubrication cavity
is full and no more grease should be added
at this time.

There are no provisions in the bearing cavity to
drain or flush the lubricant. The pump and pedestal
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) pedestal, fill
the cavities through the lubrication fittings with ap­
proximately 2 ounces (57 grams) of grease each.

For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
lubricant.

Seal Assembly

Fill the bottle oiler (10) with SAE No. 30 non‐deterg­
ent oil. Check the oil level regularly and keep the
bottle oiler full.

Power Source

Consult the literature supplied with the power
source, or contact your local power source repre­
sentative.
