Valve Plate and Endcap Installation
1. Install the alignment pins (B010) in housing.
2. Clean the valve plate (C025) and endcap (G100).
For proper pump operation, it is extremely important to ensure that there is no contamination
between the endcap and valve plate.
3. Apply a liberal amount of assembly grease to the backside of the valve plate surface to hold it in place
and position on endcap in original position.
4. Install new gasket (G150).
Do not bend or warp the gasket in an attempt to straighten it. This may damage the embossing
which is not visible under the rubber coating.
5. Install endcap. Using a 10 mm internal hex wrench install cap screws (G350) and (G400).
6. Use torque sequence shown at right.
