MAINTENANCE & REPAIR

larly through the sight gauge (10A)

and maintain it

at the midpoint of the gauge. When lubrication is
required, remove the air vent (13A) and add SAE
No. 30 non‐detergent oil through the opening.
When lubricating a dry (overhauled) intermediate,
fill the bearing cavity with approximately 50 ounces
(1,5 liters). Clean and reinstall the air vent. Do not
over‐lubricate. Over‐lubrication can cause the
bearings to over‐heat, resulting in premature bear­
ing failure.

NOTE

The white reflector in the sight gauge must be posi­
tioned horizontally to provide proper drainage.

Under normal conditions, drain the bearing hous­
ing once each year and refill with clean oil. Change
the oil more frequently if the pump is operated con­

tinuously or installed 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.

Engine

Consult the literature supplied with the engine, or
contact your local engine representative.
