2 Clean the debris from the check valve, especially at the O-Ring seats.
3 Lubricate O-Ring before installing check valve assembly.
4 Insert the check valve assembly (16) or check cap (30) into corresponding pump bore as
shown (see
Figure 2 ) . Press the assembly squarely over receiving cylindrical surface until O-
Ring seats firmly over the surface and holds assembly in position.
5 Insert new or cleaned strainer (17) into bore, over check valve assembly.
6 Clean debris from strainer cover O-Ring groove and install O-Ring (18). If O-Ring does not
stay in place, use a small amount of all purpose grease to hold the O-Ring in groove.
7 Install strainer cover (19) with screws (21). Hand tighten, alternating between each screw to
keep the cover parallel to the casing face. Torque the screws to 150 in. lbs (17 Nm). Do not
overtighten. Overtightening may cause damage to screw or casing.
8 Replace the plug (11) in the hole located to the right of the strainer cover (see Figure 1 on
page 8 ).
