circumference of the check valve body,
do not
cover the holes with the rebuild
clamp.
17.
Loosen and remove the cage.
18.
Remove the compression spring, discharge poppet guide, discharge poppet and discharge
poppet seat. Discard the poppet, poppet seat, poppet guide and compression spring.
These components will not be reused.
19.
Repeat these steps for the remaining discharge check valves.
Lapping the Discharge Check Valve Body
The check valve body is lapped with the discharge poppet and seat removed to
prevent contamination when lapping.
1.
Use the glass lapping plate from the tool kit and 320 grit lapping paper from the repair kit.
2.
Lightly wet the paper with water. Place the inlet face of the check valve body against the
lapping paper. Use even, deliberate strokes, rotating the valve body approximately 10-15
degrees after each stroke.
Be very careful not to rock the valve body while lapping the surface. Flatness is
very critical.
3.
Lap the valve body until it is flat and smooth. Be careful not to cause additional damage
by tilting or tipping the part while lapping.
4.
Thoroughly clean the openings in the check valve body to remove particles from the
lapping process.
