The pump is made up of two basics sub-assemblies. They are the Wet End Assembly (Items 1-10); and the Drive Magnet, Bracket and Motor Assembly (Items 11-15). To separate the 2 assemblies, simply remove the 4 round head screws (Item 1). The pump will then separate into the 2 sub-assemblies. The water will still be contained within the Wet End assembly unless you loosen the screws (Item 10) on the rear of the Wet End assembly. LUBRICATION: The motor should be oiled at least once a year at the star
