    It is recommended that the pressure relief valve assembly be replaced at each overhaul, or any time the pump overheats and activates the valve. Never replace this valve with a substitute which has not been specified or provided by the Gorman-Rupp Company.

    Periodically, the valve should be removed for inspection and cleaning. When reinstalling the relief valve, apply ‘Loctite Pipe Sealant With Teflon No. 592’, or equivalent compound, on the relief valve threads. Position the valve as shown in Figure 1 with the discharge port pointing down.

    Bearings (Figure 2)

    The bearing housing was fully lubricated when shipped from the factory. Check the oil level regularly through the sight gauge (19)and maintain it at the middle of the gauge. When lubrication is required, add SAE No. 30 non-detergentoil through the hole for the air vent (11). Do not over-lubricate.

    Over-lubrication can cause the bearings to overheat, resulting in premature bearing failure.
