nents or complete pump replacement will most likely be
required.
If paint has dried on internal pump parts, compo-
pump gasket to pump housing. Slide spray pump onto
drive shaft. Align tab on pump with slot on pump drive
housing.
IMPORTANT: Do not attempt to clean internal pump
components with solvents as component damage
will occur.
9. Secure spray pump to pump drive housing with two
(2) socket head screws and lock washers. Torque sock-
et head screws from 22 to 28 in–lb (2.5 to 3.2 N–m). DO
NOT over tighten screws.
2.
Inspect check valve kit and diaphragm assembly for
deformation, erosion of sealing areas or debris. If indi-
vidual valves are damaged, replace check valve kit. If
wobbler plate/diaphragm is damaged, replace pump.
10.If fittings and/or filter were removed from pump as-
sembly, install new o–ring, slide fitting or filter into hous-

3.
Inspect pump endbell and drive housing bearings.
Bearings should rotate freely with no evidence of wear
or roughness. Bearing seals should be intact and show
no signs of lubricant leakage.
