Water Pump Maintenance: 6-2
PERIODIC MAINTENANCE
Change the oil after the first 50 hours of operation, with the pump stopped and the oil still
warm, and after every 300 operating hours or 3 months of operation. When changing the
oil, remove the drain plug on the oil drain hose so all oil and accumulated sediment will
drain out.
The initial oil change is recommended for no other reason than to eliminate impurities that
may be in the oil during the running-in phase. If these impurities are not removed, but are
allowed to remain in the oil, they may cause premature wear to the moving parts and the
oil seals.
If the pump works in conditions with high humidity and with sharp temperature changes,
condensation may appear inside the crankcase. Condensation mixing with the oil can
change the oil’s properties, which is easy to detect because the oil changes to a white,
milky color.
If the pump does not have excessive water leaking from the packings, and the oil becomes
milky, the oil has to be changed more frequently.
